Proctalgia fugax can be defined as transitory but recurrent anal pain. Although its etiology remains unknown, an internal anal sphincter spasm seems to be the most likely, so that the different treatments focus on reducing the pressure of the internal anal sphincter. This study is aimed at evaluating the effectiveness of botulinum A toxin in the treatment of proctalgia fugax. Prospective clinical trial of patients with proctalgia fugax treated with botulinum A toxin at the Outpatient Clinic attached to the Coloproctogy Unit, University Hospital of Elche, from January 1999 to January 2002. The patients included in the study underwent rectal digital examination, anuscopy, rectoscopy, anal manometry and ultrasonography, barium enema and pelvic CT scan to rule out any organic cause for anal pain. The treatment consisted of 25 IU of botulinum A toxin, with a supplementary dose of 50 IU in those patients with persistence of anal pain episodes within the next two months. The patients were reviewed on the first week, second month, sixth month and first and second year. Anal pain was measured by the patients, using a linear analogue scale from 0 to 10, and continence was assessed at every visit using the Cleveland Continence Grading Scale. Five patients were recluted for the study, with a predominance of females (4 vs. 1). Mean age was 45 years. Length of symptoms prior to the treatment was 13 months (range: 6-18 months). Only one female patient required a second dose of botulinum A toxin to handle the anal pain. All the patients healed and remained free of pain up to finishing the follow-up. There were no local complications. Anal manometry showed an increased MRP (mean resting pressure) in comparison to a control group of patients (114 mmHg vs. 66 mmHg; p < 0.001) that restore to normal values after the treatment (75.65 mmHg). As for the MSP (mean squeeze pressure), it showed no difference with respect to the control group nor did it vary after the treatment. Botulinum A toxin offers a high rate of healing with no associate morbidity in the treatment of proctalgia fugax.

The diagnostic criteria for irritable bowel syndrome (IBS) have recently been updated from Rome III to Rome IV. Whereas in Rome III a diagnosis of IBS entailed chronic abdominal pain or discomfort at least 3 days per month, in Rome IV the term discomfort has been removed and the frequency of abdominal pain increased to at least 1 day per week. We examined how this change in IBS criteria impacts on clinical characteristics and pathophysiological factors. A total of 542 Swedish subjects with Rome III IBS completed a baseline questionnaire enquiring for the number of abdominal pain days in the last 10 days; this was subsequently used as a surrogate marker to identify Rome IV IBS, in that (a) those with 0 or 1 day of pain were classed as Rome IV-negative, and (b) those with ≥2 days of pain were classed as Rome IV-positive. Comparisons were made between Rome IV-positive and -negative IBS groups for demographics, IBS subtype, gastrointestinal and psychological symptoms, somatisation, fatigue, disease-specific quality of life, rectal sensitivity, and oro-anal transit time. Overall, 85% of Rome III IBS patients fulfilled the Rome IV criteria for IBS, but 15% did not. Rome IV-positive subjects were significantly more likely to be female, have poorer quality of life, greater pain severity, bloating, somatisation, fatigue, and rectal sensitivity than Rome IV-negative subjects. There were no differences in severity of anxiety or depression, IBS subtypes, bowel habit dissatisfaction, or oro-anal transit time. Finally, increasing number of pain days correlated positively with symptoms and visceral hypersensitivity. Most Rome III-positive IBS patients seeking healthcare fulfil the Rome IV IBS criteria. They constitute a more severe group than those who lose their IBS diagnosis.

Anorectal and Pelvic Pain

Bharucha, Adil E.; Lee, Tae Hee

2016-01-01

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 three 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 two 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 pharmacologic, behavioral, and physical therapy. Opioids should not be avoided, and surgery has a limited role, primarily in refractory interstitial cystitis. PMID:27712641

Functional anorectal pain occurs in the absence of any clinical abnormality. It is common and disabling; it has previously been reported in only a few studies involving small patient numbers. This study aimed to report the clinical characteristics and treatment outcomes for patients with functional anorectal pain. Patient demographics, clinical history, and tests results for all referrals for anorectal physiological testing between 1997 and 2009 were prospectively recorded. For patients with functional anorectal pain, further information was gained from clinical notes. Clinical history, anorectal physiology, and radiological imaging data were recorded for all patients; treatment outcome was noted for patients treated and followed up at the present unit. One hundred seventy patients, 99 female, with a median age of 48 years (range, 18-86), were studied. Patients were classified as having chronic proctalgia (pain duration ≥20 min, 158 patients) or proctalgia fugax (pain duration <20 min, 12 patients). The pain was most commonly located in the anal canal (90%) and aggravated by defecation or sitting (66%). A third of patients had a history of psychological disturbance. Internal anal sphincter thickness correlated with resting anal pressures. Patients with proctalgia fugax had a higher internal anal sphincter thickness and resting pressure than patients with chronic proctalgia, whereas patients with a family history of similar symptoms were more likely to have proctalgia fugax and higher resting pressures and internal anal sphincter thickness compared with those without a family history of these symptoms. Patients referred for treatment underwent a range of interventions including biofeedback (29 patients, 17 improved), tricyclic antidepressants (26 patients, 10 improved), Botox injection (9 patients, 5 improved), and sacral nerve stimulation (3 patients, 2 improved). Biofeedback had the greatest treatment effect, especially in patients with defecatory dysfunction. Biofeedback is beneficial in the subset of patients with functional anorectal pain and difficulty with defecation. Tricyclic antidepressants, Botox, and sacral nerve stimulation may also have a role.

Normal Anal Examination After Penetration: A Case Report.

PubMed

Slingsby, Brett; Goldberg, Amy

2018-03-01

Physical findings are rare after anal penetration. Furthermore, children delay in disclosing or are reticent to discuss penetration. A 12-year-old boy presented to medical care multiple times over a several-week period complaining of abdominal pain, bloody diarrhea, and poor appetite. On colonoscopy, he was found to have a cylindrical foreign body (measuring 7 cm tall and 7 cm in diameter) in his rectum, which had been present for at least 2 weeks. He initially denied knowing how the object got into his rectum and later stated that he inserted it himself out of curiosity. One week after the object was removed, follow-up examination using video colposcopy revealed a completely normal anal examination; the patient had a normal anal examination despite known anal penetration and removal of the object. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Children can have a normal anal examination despite anal penetration, and do not always disclose anal penetration. The aforementioned concepts can be applied to situations related to child sexual abuse in the emergency department, where physical examinations are frequently normal and children delay in disclosing the abuse. When there is concern for sexual abuse, even in the absence of a disclosure or examination findings, patients should be referred for a child abuse pediatrics evaluation if available.

Chronic anal fissure (CAF) onset, exacerbation, and impact on quality of life are influenced by a host of psychological, physiological, and social factors. We aimed to investigate the difference in psychopathology and stress between normal and CAF groups. Thirty CAF patients and 20 age-sex matched healthy controls were evaluated for Axis I psychopathology, depression, anxiety, and stress with Hamilton and Hospital Depression-Anxiety Scales, Perceived Stress Scale, and SF-36. With a mean age of 39.47, 83.3% of CAF patients were female. Anxiety-depression and stress scores were all significantly higher and functionality was lower in the CAF group compared to controls (p < 0.001); 36.7% of the patients had a triggering stress factor and 56.6% had an exacerbating stress factor; 56.7% of the patients had an ongoing Axis I psychopathology while 50% had a previous psychopathology. Pain (96.7% had pain (VAS = 6.55)) and bleeding (83.3% had bleeding (VAS = 4.14)) severity showed a negative impact on bodily pain and role limitations emotional subscales of SF36. There is a high comorbidity of psychopathology in the CAF patients and depression and anxiety severities show a negative impact on the quality of life. Stress acts as both a triggering and an exacerbating factor in CAF.

Anal fissure is associated with anal pain and bleeding. Lateral internal sphincterotomy (LIS) has been a common form of surgical management. This can however cause incontinence and hence an equally effective alternative without this risk would be ideal. Anal fissurectomy and an anal advancement flap (AAF) have been used as an alternative to LIS. We carried out a retrospective analysis of the results of AAF and LIS for the treatment of anal fissure. Fifty patients underwent AAF and a further 50 cases were chosen who had undergone LIS over the same time period. Patient and procedural data were collected including post-operative course. Presenting symptoms included anal pain (94%), rectal bleeding (77%) and constipation (15%). Mean (±SD) follow-up was 20 ± 12 months in the AAF group vs 22 ± 12.5 months in the LIS group. Healing of fissure was achieved in 96% of patients after AAF and 88% after LIS (p = 0.27). Resolution of symptoms was achieved in 90% after AAF and 72% of patients after LIS (p = 0.04). LIS was associated with an increased incidence of readmission with infection and pain (8% vs 4%, p = 0.35). Seven patients whom had undergone successful AAF with complete resolution of symptoms had previously had LIS with failure of symptom relief. There was no incidence of faecal incontinence in either group. AAF is associated with a higher incidence of symptomatic relief and fissure healing and lower incidence of complications when compared with LIS. AAF is effective at healing fissures which are refractory to LIS.

Internal sphincter and the nature of haemorrhoids.

PubMed Central

Hancock, B D

1977-01-01

Internal anal sphincter activity has been studied in 84 patients with haemorrhoids and 40 asymptomatic subjects. Activity was estimated by measuring maximum resting anal pressure with a water filled anal balloon probe 7 mm in diameter connected to a strain gauge pressure transducer. There was greater activity of the internal sphincter in patients with haemorrhoids than in controls, but there was no significant relationship between sphincter activity and duration of symptoms, predominant symptom (bleeding or prolapse), severity of symptoms, history of pain, history of straining at stool, or size of haemorrhoids. Straining at stool occurred significantly more often in patients whose main complaint was prolapse than in those whose main complaint was bleeding. Anal dilatation reduced sphincter activity and the best clinical results were obtained in those with the most active sphincter. An internal sphincter abnormality may be an aetiological factor in some patients but there must be other factors as well. Straining at stool may determine whether bleeding or prolapse is the predominant symptom. Images Fig. 1 PMID:892612

An 18-year-old female patient arrived at the emergency department complaining of abdominal pain and fullness after a heavy meal. Physical examination revealed she was filthy and cover in feces, and she experienced severe abdominal distension. She died in ED and a diagnostic autopsy examination was requested. At external examination, the pathologist observed a significant dilation of the anal sphincter and suspected sexual assault, thus alerting the Judicial Authority who assigned the case to our department for a forensic autopsy. During the autopsy, we observed anal orifice expansion without signs of violence; food was found in the pleural cavity. The stomach was hyper-distended and perforated at three different points as well as the diaphragm. The patient was suffering from anorexia nervosa with episodes of overeating followed by manual voiding of her feces from the anal cavity (thus explaining the anal dilatation). The forensic pathologists closed the case as an accidental death. © 2018 American Academy of Forensic Sciences.

Modified perianal/pericapsular anesthesia for transrectal biopsy of prostate in patients with anal rectal problems.

Kravchick, Sergey; Yoffe, Boris; Cytron, Shmuel

2007-01-01

To modify our technique of perianal anesthesia and use it in patients with painful conditions of the rectum and/or anus. A total of 31 consecutive patients with anal-rectal problems underwent prostate needle biopsy. Of these, 17 were referred to our hospital after vain attempts to insert a transrectal ultrasound probe. Patients received a perianal-pericapsular injection of 1% lidocaine. Pain perception was separately assessed for probe insertion and biopsies using a visual pain analog score. Only in 1 patient were we unable to insert the transrectal ultrasound probe. The mean patient age was 65.28 +/- 5.35 years. We performed a mean of 12.25 biopsies per case. At probe insertion, the mean pain score was 2.2 +/- 0.83. During the biopsy punctures, the mean pain level was 2.53 +/- 1.054. We did not find any increase in the complication rate related to the anesthesia method. Modified perianal anesthesia can be used for transrectal ultrasound-guided biopsy of the prostate in patients with anal-rectal problems, because it provides significant pain relief.

In prolapsed internal hemorrhoids exposed outside the anus, manually reducing the prolapse with 48 hours of commencement of anal pain, decreased the progression of thrombosis. The aim of our study was to evaluate the effects of manual reduction of the inflamed piles hemorrhoids. Eleven patients, 7 males and 4 pregnant females (in early post partum) with an average age of 34 years ± 8 (range 23- 52) were enrolled with anal pain cause by haemorrhoidal congestion, but prior to full blown thrombosis. Patients underwent a manual reduction of the external prolapsed haemorrhoidal plexus. In the 48 hours following the procedure, patients were instructed on how to insert any prolapsed hemorrhoid (piles) themselves. Pain intensity was measured using the visual analog scale (VAS) at time of consultation and then 10 days after the reduction. At day 10 following treatment we observed a statistically significant reduction in anal swelling (11 vs 1, n° pzt; p = 0.001), anal pain (11 vs 2, n° pzt; p = 0.001) and VAS score (8.6 ± 0.7 vs 0.4 ± 1.2; p = 0.001). Two patients (18%) underwent surgical haemorrhoidectomy sec. Milligan Morgan and 1 patient (9%) underwent excision of thrombosed external hemorrhoids. 73% of patients did not require surgery. Manual reduction of the prolapsed piles outside the anus decreased pain immediately and it also allows postponement of surgery or any other treatment.

Anal fissures, proctalgia fugax, levator ani syndrome, and pruritus ani are common causes of anorectal pain and irritation. The clinician who obtains a thorough history and performs a complete examination can accurately diagnose these disorders. Ancillary tests seldom are helpful and rarely are necessary. Most patients suffering from these conditions readily respond to conservative therapy provided in the primary care practitioner's office.

Rectal and perianal pain is a common problem. Most people have experienced it at least once in their lifetime. It usually manifests as mild discomfort, but sometimes the pain can be so severe that it is incapacitating. A 59-year-old woman admitted with a 2-year history of paroxysmal perianal pain underwent a full work-up including proctoscopy, sigmoidoscopy, full colonoscopy, and barium enema that were unremarkable. Lumbosacral magnetic resonance imaging with and without gadolinium showed an intradural-extramedullary lesion at the level of L5. The pathologic diagnosis was a neurofibroma. She underwent surgery, and after a few weeks she felt well and medication was no longer needed for her paroxysmal pain. Although one should consider the usual causes of colorectal pain such as hemorrhoids, anal fissure, proctalgia fugax, and chronic perianal pain syndrome, we should keep in mind that some referral pain may mimic local pathologies and should be evaluated properly.

'Arsha' (hemorrhoids) is an ailment that affects all economical groups of population. Though the disease is within the limits of management, it has its own complications like severe hemorrhage, inflammation, and thrombosis, by which a patient gets severe pain and is unable to continue his routine work. Prior to surgical treatment of hemorrhoids, associated conditions like inflammation, strangulation, thrombosis, etc. need to be managed. Thrombosed piles possibly occur due to high venous pressure associated with severe anal pain. Leech (Hirudina medicanalis) application is found to be effective in reducing pain. In thrombosed piles, leech application has shown thrombolytic action, which contributes in re-establishment of circulation. It is observed in the study that, pus and mucous discharge have been reduced after leech application; which may be due to antimicrobial and mucolytic properties of leech. This method of treatment is found to be effective and increase the quality of life in patients suffering with thrombosed piles.

A Case Series of Anal Carcinoma Misdiagnosed as Idiopathic Chronic Anal Fissure.

2017-09-01

Chronic anal fissure is a linear ulcer in the anal canal that has not cicatrized for more than 8-12 weeks of treatment. Most anal fissures are idiopathic and are located in the posterior midline. Squamous cell carcinoma of the anus commonly presents as bleeding and anal pain. It may also present as a mass, nonhealing ulcer, itching, discharge, fecal incontinence and fistulae. Not uncommonly, small and early cancers are misdiagnosed as benign anorectal disorders like anal fissures or hemorrhoids. The clinical suspicion of squamous cell carcinoma of the anus is of paramount importance in patients with nonhealing anal fissures, fissures in atypical positions or with indurated or ulcerated anal tags and in patients with risk factors for the development of anal squamous intraepithelial lesions that are precursors of invasive anal squamous cell carcinoma. The authors present 3 cases of squamous cell carcinoma of the anus initially misdiagnosed as benign chronic anal fissure.

To compare the efficacy and complication of tissue selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) in the treatment of severe hemorrhoids. Clinical data of 542 cases of severe hemorrhoids undergoing TST (258 cases) or PPH (284 cases) in The First Affiliated Hospital of Fujian Medical University from November 2010 to January 2012 were analyzed retrospectively. Operative parameters, efficacy and complication 3 months after operation were assessed and compared. No significant difference in cure rate between TST and PPH (96.5% vs. 95.4%) was found, while the operation time and hospital stay after operation in TST group were significantly shorter urgency [(20.6±4.7) vs. (26.4±6.3) min, (2.9±0.5) vs. (3.5±0.7) d, both P<0.05]. Incidences of postoperative pain, bleeding, anal urgency and urinary retention in TST group were significantly lower than those in PPH group (all P<0.01). No anal stenosis was observed in TST group, and 5 cases developed anal stenosis in PPH group (P<0.05). Hemorrhoid recurrence did not differ significantly between the two groups. The efficacy of TST and PPH is comparable for severe hemorrhoids patients, while TST is associated with faster postoperative recovery and less complications.

Increased anal basal pressure in chronic anal fissures may be caused by overreaction of the anal-external sphincter continence reflex.

PubMed

van Meegdenburg, Maxime M; Trzpis, Monika; Heineman, Erik; Broens, Paul M A

2016-09-01

Chronic anal fissure is a painful disorder caused by linear ulcers in the distal anal mucosa. Even though it counts as one of the most common benign anorectal disorders, its precise etiology and pathophysiology remains unclear. Current thinking is that anal fissures are caused by anal trauma and pain, which leads to internal anal sphincter hypertonia. Increased anal basal pressure leads to diminished anodermal blood flow and local ischemia, which delays healing and leads to chronic anal fissure. The current treatment of choice for chronic anal fissure is either lateral internal sphincterotomy or botulinum toxin injections. In contrast to current thinking, we hypothesize that the external, rather than the internal, anal sphincter is responsible for increased anal basal pressure in patients suffering from chronic anal fissure. We think that damage to the anal mucosa leads to hypersensitivity of the contact receptors of the anal-external sphincter continence reflex, resulting in overreaction of the reflex. Overreaction causes spasm of the external anal sphincter. This in turn leads to increased anal basal pressure, diminished anodermal blood flow, and ischemia. Ischemia, finally, prevents the anal fissure from healing. Our hypothesis is supported by two findings. The first concerned a chronic anal fissure patient with increased anal basal pressure (170mmHg) who had undergone lateral sphincterotomy. Directly after the operation, while the submucosal anesthetic was still active, basal anal pressure decreased to 80mmHg. Seven hours after the operation, when the anesthetic had completely worn off, basal anal pressure increased again to 125mmHg, even though the internal anal sphincter could no longer be responsible for the increase. Second, in contrast to previous studies, recent studies demonstrated that botulinum toxin influences external anal sphincter activity and, because it is a striated muscle relaxant, it seems reasonable to presume that it affects the striated external anal sphincter, rather than the smooth internal anal sphincter. If our hypothesis is proved correct, the treatment option of lateral internal sphincterotomy should be abandoned in patients suffering from chronic anal fissures, since it fails to eliminate the cause of high anal basal pressure. Additionally, lateral internal sphincterotomy may cause damage to the anal-external sphincter continence reflex, resulting in fecal incontinence. Instead, higher doses of botulinum toxin should be administered to those patients suffering from chronic anal fissure who appeared unresponsive to lower doses. Copyright © 2016 Elsevier Ltd.

Chronic idiopathic anal pain (CIAP) remains a diagnosis of exclusion. Its study and management still lack a standardized protocol. The aim of this study is to evaluate the results obtained with the diagnostic-therapeutic protocol established in our service. We performed a retrospective study of patients diagnosed with CIAP at the Colorectal Unit of the General University Hospital of Elche, between 2005 and 2011. We evaluated 57 patients with a diagnosis of chronic anal pain for functional anorectal disease (FAD). After the application of our diagnostic protocol, final diagnosis of chronic anal pain (CAP) was achieved in 43 cases (75%), including 22 cases of descending perineum syndrome, 12 of proctalgia fugax, 2 of pudendal neuritis and 7 of coccydynia. In 14 patients exclusion diagnosis of CIAP was established. Among the therapies used on patients with CIAP, biofeedback combined with conservative measures improved symptoms in 43% of the cases. Sacral nerve stimulation was assessed in patients who did not respond to other treatments. Through proper anamnesis, physical examination and complementary tests, a specific diagnosis of the cause of CAP by FAD can be achieved, reducing exclusion diagnosis of CIAP to 25% of cases. Conservative measures combined with biofeedback achieved an improvement in pain in more than 40% of the cases of CIAP in our study. Sacral nerve stimulation can be considered as a treatment option in refractory cases. Copyright © 2013 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

Anal fissures are associated with hypertonia of the internal anal sphincter and pain. We evaluated the efficacy of local application of a combination of minoxidil and lignocaine in healing anal fissures. In this prospective, randomized, double-blind study, 90 patients with anal fissure were recruited. Patients received local applications of ointments containing 5% lignocaine (n=28), 0.5% minoxidil (n=36), or both (n=26). Healing of anal fissure at 6 weeks was used as the primary end-point. Rates of complete healing of fissure were similar in the three groups (lignocaine alone 8/27, minoxidil alone 10/34, combination 7/22; p=ns). Mean (SD) time taken for complete healing with combination treatment [1.9 (0.6) weeks] was significantly shorter than that with minoxidil alone (3.1 [1.7] weeks; p=0.001) or with lignocaine alone (3.3 [0.8] weeks; p=0.002). Rates of pain relief were similar in the three groups. Stoppage of bleeding occurred more often with combination treatment than with lignocaine alone. No patient had systemic or local side effects. Combination treatment with minoxidil and lignocaine helps in faster healing of anal fissures and provides better symptomatic relief than either drug alone.

Hemorrhoids are a very common condition. The treatment depends upon persistence and severity of symptoms. For hemorrhoids of II and III grade the rubber band ligation may be therapeutic. Our aim is to report the outcomes of rubber band ligation of hemorrhoids, with a follow up of 6 months. A total of 50 patients underwent rubber band ligation for symptomatic hemorrhoids (grade II and III) without prolapse, between June 2012 and June 2014. All patients underwent plug test to rule out presence of rectal mucosal prolapse and were classified according to PATE classification (1). Each hemorrhoid was ligated with one rubber band through a ligator. All patients were evaluated immediately at the end of the procedure, after ten days and six months after the treatment. Patient's demographic and operative data were collected and analyzed. The mean patients age was 47.6±12.3 years (range 24-72). All procedures were performed without complications. Before rubber band ligation, 42 patients had rectal bleeding, 38 had perineal discomfort and 27 had itching. Ten days after the treatment, 12 patients presented self-limited rectal bleeding, but 10 of these had more hemorrhoids and underwent a second rubber band ligation. No patients complained perineal discomfort, and 8 patients had itching; 78% and 16% of patients respectively, experienced feeling of a foreign body inside the canal anal and anal pain. After 6 months, only 13 patients were occasionally symptomatic: 4 patients had rectal bleeding, 2 had perineal discomfort and 4 had itching. Three more patients presented both perineal discomfort and hitching. None had the feeling of a foreign body in anal canal or anal pain. Rubber band ligation is an efficacious, cost-effective and simple treatment for the second and third degree hemorrhoids without rectal mucosal prolapsed. In our hands, no severe complications developed and minor complications could be handled with ease.

Objective To evaluate the effect of the fetal head station at attempted operative vaginal delivery (aOVD), and specifically midpelvic or low aOVD, on urinary incontinence (UI), anal incontinence (AI), and perineal pain at 6 months. Design Prospective cohort study. Setting 1941 women with singleton term fetuses in vertex presentation with midpelvic or low aOVD between 2008 and 2013 in a tertiary care university hospital. Methods Symptoms of urinary incontinence (UI) using the Bristol Female Lower Urinary Tract Symptoms questionnaire, and symptoms of anal incontinence (AI) severity using Fecal Incontinence Severity Index (FISI) were assessed 6 months after aOVD. We measured the association between midpelvic or low aOVD and symptoms of UI, AI, and perineal pain at 6 months using multiple regression and adjusting for demographics, and risk factors of UI and AI, with adjusted odds ratios (aORs) and 95% confidence intervals (95% CI). Results The study included 907 women (46.7%) who responded to the questionnaire; 18.4% (167/907) had midpelvic aOVD, and 81.6% (740/907) low; and none of women with symptoms of UI (26.6%, and 22.4%, respectively; p = 0.31), AI (15.9%, and 21.8%; p = 0.09), the FISI score, and perineal pain (17.2%, and 12.7%; p = 0.14) differed significantly between groups. The same was true for stress, urge, and mixed-type UI, severe UI and difficulty voiding. Compared with low pelvic aOVD, the aORs for symptoms of UI in midpelvic aOVD were 0.70 (0.46–1.05) and AI 1.42 (0.85–2.39). Third- and fourth-degree tears were a major risk factor of symptoms of UI (aOR 3.08, 95% CI 1.35–7.00) and AI (aOR 3.47, 95% CI 1.43–8.39). Conclusion Neither symptoms of urinary nor anal incontinence differed at 6 months among women who had midpelvic and low pelvic aOVD. These findings are reassuring and need further studies at long-term to confirm these short-term data. PMID:27992558

Radiation proctitis, is a relatively frequent complication resulting from the direct or collateral irradiation of the rectum in radiotherapy treatment for genito-urinary or anorectal malignancies. The main symptoms are diarrhoea, tenesmus, proctorrhagia, anal pain, mucorrhoea and faecal incontinence. The evolution of chronic radiation proctitis requires treatment for related anaemia, anal incontinence and micturition disorders. The approach and type of treatment depend on the severity of the symptoms and on the endoscopic aspect, in relation to the response to previous medical therapy performed. In our experience, endoscopic treatment is the best choice in the presence of ongoing bleeding and the possible development of severe anaemia. The surgical option is mandatory in patients at high risk of sepsis, requiring a faecal diversion constructed using the Hartmann technique. We report two cases, observed during the last two years, one treated with endoscopic bipolar coagulation and the other with a double urinary and faecal diversion.

Over the last few decades, incidence of anal cancer among HIV-positive men has been on the rise. In this context, programmes of screening and treatment of anal dysplasia which is a precursor of anal cancer have been developed. The aim of our study was to describe the efficiency, side effects and outcome of anal dysplasia treatment in a population of HIV-positive men who have sex with men (MSM). We performed a retrospective study of HIV-positive MSM who received treatment for anal dysplasia between May 2010 and February 2014 in the Saint-Pierre University Hospital, Brussels. The different treatments used were electrocautery (ECA), infrared coagulation (IRC), surgical treatment and imiquimod. Seventy-three HIV-infected MSM were included in the study, counting 62% of HGAIN. Median age was 41 years. Eighty-one per cent were on HAART. Median CD4 cell count was 525 cell/mm³, and 65% had undetectable viral loads. A total of 139 therapeutic interventions were recorded during the study period, and two-thirds of the enrolled patients received more than one treatment. At 540 days of follow-up, the rate of treatment response was 62%. Fifty per cent of the persistent HGAIN were metachronous lesions. No severe adverse events were recorded but frequent treatment-associated discomfort was reported, such as pain, self-limited bleeding, infection and anal irritation. Treatment of anal dysplasia appears to be safe and to offer short-term efficiency. However, its long-term efficiency remains unknown, especially in the HIV-positive population in which spontaneous clearance is lower and rate of recurrence higher.

Proctalgia fugax (PF) is a benign, self-limiting disease characterized by episodes of intense anorectal pain at frequent intervals in the absence of organic proctological disease. Even though PF was described more than a century ago, its etiology remains unclear. Currently there is no information available. Few papers quoting many ways of management have been published. The aim of this study was to investigate patients complaining of this condition and to treat them with sequential therapy. We devised a descriptive, prospective study of patients complaining of acute perianal pain--duration less than 30 minutes--without organic disease or previous perianal surgery since 1996 to 2002 in our Department. We treated these patients using a three-step treatment (1: information, hip bath, benzodiazepines; 2: sublingual nifedipine 10 mg, or topic 0.1% nitroglycerin on demand; 3: internal anal sphincterotomy if hypertrophy of the internal anal sphincter was demonstrated by anal ultrasonography and no improvement was confirmed with the previous steps of treatment). We defined remarkable improvement as a decrease in the number of episodes by half or in pain intensity by 50%. Fifteen patients with an average follow-up of 4 years. Anal endosonography confirmed a grossly thickened internal anal sphincter (IAS) in 5 cases. After the first step of treatment 7 patients improved and 1 patient was cured; after the second step of treatment 3 patients improved and 1 was cured; the third step was applied to 3 patients with a thickened IAS; 1 patient improved and 1 patient was cured. A total resolution of PF is not always possible, but we may improve symptoms and their frequency. Almost 50% of patients in our series improved with the first step of treatment; 30% of our patients had IAS hypertrophy. Anal endosonography can help in the diagnosis of organic diseases or IAS hypertrophy, for which we can perform an internal anal sphincter myectomy.

Intra- and early (first week) post-operative haemorrhages are the most common complications in stapled hemorrhoidectomy PPH (Procedure for Prolapse and Hemorrhoids) and in circumferential resection of the rectal prolapse STARR (Stapled Trans Anal Rectal Resection). Performing PPH and STARR we employed a gelatin based haemostatic sealant with thrombin component (FloSeal) to control intra-operative bleeding and to reduce post-operative bleeding avoiding haemostatic stitches on suture line. We report the preliminary results on 197 PPH and 64 STARR; 44 PPH (22.4%) and 27 STARR (42.2%) were treated by FloSeal. No major post-operative bleeding was observed in all patients treated by FloSeal, compared to 1.3% and 2.7% of hemorrhage respectively in PPH and STARR patients treated without sealant. Post-operative pain was less severe in patients treated by FloSeal, without a difference statistically significant. The data are preliminary and must be confirmed in prospective randomized trials in larger series.

Some haemorrhoids are associated with high resting anal canal pressures. The aim of this study was to assess if Rectogesic, a topical glyceryl trinitrate 0.2% ointment was effective in relieving symptoms of early grade haemorrhoids associated with high resting anal canal pressures. This was a prospective, two-centre, open label study of 58 patients with persistent haemorrhoidal symptoms. Patients with first or second degree haemorrhoids and a maximum resting anal canal pressure > 70 mmHg were included. Rectogesic was applied three times a day for 14 days. Anorectal manometry was performed 30 min after the first application of Rectogesic. A 28-day diary was completed during 14 days of therapy and for 14 days after cessation of treatment. This recorded the incidence of rectal bleeding, and visual analogue scales for anal pain, throbbing, pruritus, irritation and difficulty in bowel movement. Maximum resting anal canal pressures were reduced after application of Rectogesic (115.0 +/- 40.4 mmHg vs 94.7 +/- 34.1 mmHg, P < 0.001). In the study period and at 14 days after cessation of Rectogesic, there was significant reduction in rectal bleeding (P = 0.0002), and significant improvement of anal pain (P = 0.0024), throbbing (P = 0.0355), pruritus (P = 0.0043), irritation (P = 0.0000) and difficulty in bowel movement (P = 0.001). The main adverse event was headache in 43.1% of patients. Rectogesic is a safe and feasible treatment for patients with early grade haemorrhoids associated with high resting anal canal pressures.

Proctalgia fugax--short-lived anal spasm--is a common, extremely unpleasant, painful condition that occurs completely unexpectedly, often waking the victim at night. Scientific assessment is difficult on account of the functional nature of the condition and its multifactorial genesis. Before the patient is labeled "anal neurotic", however, he/she should be investigated by a specialist. The results of treating the rarely absent pathological organic findings give rise to optimism.

From 1966 to 1981, 47 patients with a diagnosis of anal carcinoma were irradiated. This group was composed of 23 males and 24 females, with age ranging from 38 to 84 years (average 64.4 years). Five patients were treated preoperatively and 34 were treated definitively with cancericidal doses of irradiation. Acute radiation reactions requiring a rest-break were noted in 28% of patients, but all were managed as outpatients without untoward chronic sequelae. Chronic complications were noted in 13 patients, including two patients who required colostomy for severe anal stenosis and two who required A-P resection for large painful ulcers. Twenty-eightmore » of 35 patients (80%) treated with irradiation alone have remained locally controlled without further treatment. An additional four have been salvaged by surgery. Only three patients had interstitial implants as part of their treatment course. Actuarial survival at five years for the N/sub 0/ patients and the group as a whole are 95.6 and 79.3%, respectively. It is concluded that external beam irradiation alone, properly fractionated to cancericidal doses, can control anal carcinoma with acceptable morbidity rates and without the use of either chemotherapy or interstitial implants in most cases. There is also a strong correlation suggesting that anal intercourse and male homosexuality play a significant role in the etiology of this disease.« less

Understanding of hemorrhoidal pathology and treatment has come a long way. The theory of a sliding anal canal lining and the knowledge that hemorrhoidal cushions are a normal part of the anal anatomy should encourage symptom control rather than radical removal of tissue. Techniques that fix the cushions back in position can be performed in outpatients with reasonable success rates. When required, surgery should be aimed at symptomatic hemorrhoids. It is hoped that new developments such as circular stapling and better pain management will promote increased day surgery, better pain control, and less time off work for patients.

In this article, we present 3 cases of patients with different types of haemorrhoidal disease. The first patient is a 27-year-old woman who had been experiencing incidental rectal blood loss without pain during defecation for 3 months. The second patient is a 76-year-old woman who had been bothered by varying degrees of pain from a swelling nearby the anus for 1 year. The third case involves a 31-year-old man who had had continuous severe pain in the anal area for 3 consecutive days. The first patient appeared to have internal hemorrhoids, whereas different forms of external hemorrhoids affected the patients in the other 2 cases. Internal haemorrhoids develop from the intraluminal corpus cavernosum recti; external haemorrhoids from the perianal marginal veins. Patients with internal haemorrhoids present with symptoms that include blood loss and prolaps feeling during defecation. In patients with external haemorrhoids pain is the prominent symptom. Internal haemorrhoids are treated either conservatively or surgically, depending upon their severity. Considering external haemorrhoidal disease surgical treatment provides the most rapid and persistent relief of symptoms.

The objectives of this study were to determine women's knowledge of human papillomavirus (HPV) and anal cancer and knowledge and attitudes toward the anal Pap test. A convenience sample of 370 women from the general population 21 years or older completed a 48-question preintervention survey; read an informational pamphlet about anal cancer, HPV, and anal Pap tests; and then completed a 21-question postintervention survey in Augusta, Atlanta, and Savannah, GA. The survey assessed their knowledge about anal cancer, HPV, and the anal Pap test and determined their attitudes toward the anal Pap test. Only preintervention results were considered in this article. Descriptive statistics were determined for all variables. Only 17.6% of women had previously heard of anal Pap tests, and the majority knew nothing (48.9%) or only a little (38.5%) about anal cancer. Yet, most women (78.6%) knew that anal Pap tests help to prevent anal cancer, and 86.2% knew that anal Pap tests are not only for people who have anal sex. Only a minority of women recognized known risk factors for anal cancer. Lack of knowledge about anal Pap tests (43.8%), pain or discomfort (41.3%), cost (24.0%), and embarrassment (21.2%) were the main reasons cited for not wanting an anal Pap test. Although most women had limited knowledge about anal cancer and anal Pap tests and few recognized known risk factors for anal cancer, women were receptive to screening. Further implementation of anal Pap testing for women may be improved by understanding women's limited knowledge and concerns.

Predicting obstetric anal sphincter injuries in a modern obstetric population.

Perineal lacerations are common at the time of vaginal delivery and may predispose patients to long-term pelvic floor disorders, such as urinary incontinence and pelvic organ prolapse. Obstetric anal sphincter injuries, which are the most severe form of perineal lacerations, result in disruption of the anal sphincter and, in some cases, the rectal mucosa during vaginal delivery. Long-term morbidity, including pain, pelvic floor disorders, fecal incontinence, and predisposition to recurrent injury at subsequent delivery may result. Despite several studies that have reported risk factors for obstetric anal sphincter injuries, no accurate risk prediction models have been developed. The purpose of this study was to identify risk factors and develop prediction models for perineal lacerations and obstetric anal sphincter injuries. This was a nested case control study within a retrospective cohort of consecutive term vaginal deliveries at 1 tertiary care facility from 2004-2008. Cases were patients with any perineal laceration that had been sustained during vaginal delivery; control subjects had no lacerations of any severity. Secondary analyses investigated obstetric anal sphincter injury (3rd- to 4(th)-degree laceration) vs no obstetric anal sphincter injury (0 to 2(nd)-degree laceration). Baseline characteristics were compared between groups with the use of the chi-square and Student t test. Adjusted odds ratios and 95% confidence intervals were calculated with the use of multivariable logistic regression. Prediction models were created and model performance was estimated with receiver-operator characteristic curve analysis. Receiver-operator characteristic curves were validated internally with the use of the bootstrap method to correct for bias within the model. Of the 5569 term vaginal deliveries that were recorded during the study period, complete laceration data were available in 5524 deliveries. There were 3382 perineal lacerations and 249 (4.5%) obstetric anal sphincter injuries. After adjusted analysis, significant predictors for laceration included nulliparity, non-black race, longer second stage, nonsmoking status, higher infant birthweight, and operative delivery. Private health insurance, labor induction, pushing duration, and regional anesthesia were not statistically significant in adjusted analyses. Significant risk factors for obstetric anal sphincter injury were similar to predictors for any laceration; nulliparity and operative vaginal delivery had the highest predictive value. Area under the curve for the predictive ability of the models was 0.70 for overall perineal laceration, and 0.83 for obstetric anal sphincter injury. When limited to primiparous patients, 1996 term vaginal deliveries were recorded. One hundred ninety-two women sustained an obstetric anal sphincter injury; 1796 women did not. After adjusted analysis, significant predictors for laceration included non-black race, age, obesity, and nonsmoking status. In secondary analyses, significant predictors for obstetric anal sphincter injury included non-black race, nonsmoking status, longer duration of pushing, operative vaginal delivery, and infant birthweight. Area under the curve for the predictive ability of the models was 0.60 for any laceration and 0.77 for obstetric anal sphincter injury. Significant risk factors for sustaining any laceration and obstetric anal sphincter injury during vaginal deliveries were identified. These results will help identify clinically at-risk patients and assist providers in counseling patients about modifications to decrease these risks. Copyright © 2016 Elsevier Inc.

Pudendal nerve decompression in perineology : a case series

PubMed Central

Beco, Jacques; Climov, Daniela; Bex, Michèle

2004-01-01

Background Perineodynia (vulvodynia, perineal pain, proctalgia), anal and urinary incontinence are the main symptoms of the pudendal canal syndrome (PCS) or entrapment of the pudendal nerve. The first aim of this study was to evaluate the effect of bilateral pudendal nerve decompression (PND) on the symptoms of the PCS, on three clinical signs (abnormal sensibility, painful Alcock's canal, painful "skin rolling test") and on two neurophysiological tests: electromyography (EMG) and pudendal nerve terminal motor latencies (PNTML). The second aim was to study the clinical value of the aforementioned clinical signs in the diagnosis of PCS. Methods In this retrospective analysis, the studied sample comprised 74 female patients who underwent a bilateral PND between 1995 and 2002. To accomplish the first aim, the patients sample was compared before and at least one year after surgery by means of descriptive statistics and hypothesis testing. The second aim was achieved by means of a statistical comparison between the patient's group before the operation and a control group of 82 women without any of the following signs: prolapse, anal incontinence, perineodynia, dyschesia and history of pelvi-perineal surgery. Results When bilateral PND was the only procedure done to treat the symptoms, the cure rates of perineodynia, anal incontinence and urinary incontinence were 8/14, 4/5 and 3/5, respectively. The frequency of the three clinical signs was significantly reduced. There was a significant reduction of anal and perineal PNTML and a significant increase of anal richness on EMG. The Odd Ratio of the three clinical signs in the diagnosis of PCS was 16,97 (95% CI = 4,68 – 61,51). Conclusion This study suggests that bilateral PND can treat perineodynia, anal and urinary incontinence. The three clinical signs of PCS seem to be efficient to suspect this diagnosis. There is a need for further studies to confirm these preliminary results. PMID:15516268

Introduction Complex anal fistulas are responsible for pain, faecal incontinence and impaired quality of life. The rectal mucosa advancement flap (RMAF) procedure to cover the internal opening of the fistula remains a strategy of choice. However, a new procedure for closing anal fistulas is now available with the use of a nitinol closure clip (OTSC Proctology, OVESCO), which should ensure a better healing rate. This procedure is currently becoming more widespread, though without robust scientific validation, and it is therefore essential to carry out a prospective evaluation in order to determine the efficacy and safety of this new medical device for complex anal fistulas. Methods and analysis The FISCLOSE trial is aimed at evaluating the efficacy and safety of a nitinol closure clip compared to the RMAF procedure for the management of complex anal fistulas. This trial is a prospective, randomised, controlled, single-blind, bicentre and interventional study. Patients (n=46 per group) will be randomly assigned for management with either a closure clip or RMAF. The main objectives are to improve the healing rate of the anal fistula, lessen the postoperative pain and faecal incontinency, enhance the quality of life, and lower the number of reinterventions and therapeutic management costs. The primary outcome is the proportion of patients with a healed fistula at 3 months. The secondary outcomes are anal fistula healing (6 and 12 months), proctological pain (visual analogue scale), the faecal incontinence score (Jorge and Wexner questionnaire), digestive disorders and quality of life (Gastrointestinal Quality of Life Index and Euroqol EQ5D-3 L) up to 1 year. Ethics and dissemination The study was approved by an independent medical ethics committee 1 (IRB00008526, CPP Sud-Est 6, Clermont-Ferrand, France) and registered by the competent French authority (ANSM, Saint Denis, France). The results will be disseminated in a peer-reviewed journal and presented at international congresses. Trial registration number NCT02336867; pre-result. PMID:26674505

Submucosal reconstructive hemorrhoidectomy has never been a popular operation due to its difficulty and duration, the amount of blood loss, and the risk of incontinence. The main indication for hemorrhoidectomy according to Parks is fourth-degree hemorrhoids with prolapse of the dentate line outside the anus and with simultaneous presence of external hemorrhoids. We report our experience in the treatment of hemorrhoids using submucosal reconstructive hemorrhoidectomy according to Parks. A total of 640 patients (381 men and 259 women) of median age 42 years (range, 18-81) were treated between 1983 and 2002; 80% of patients had fourth-degree, 19% third-degree and 1% second- degree hemorrhoids. All patients underwent rectosigmoidoscopic examination before surgery; patients over 35 years of age or with a suspected inflammatory or neoplastic disease underwent colonoscopy or barium enema. All patients underwent anorectal manometry before operation, to measure anal resting pressure, maximal squeeze and sphincter length, with the purpose of determining if an internal sphincterotomy was also necessary (in case of high anal resting tone). One-third of the patients also had an internal sphincterotomy to correct anal hypertonia. Postoperative bleeding occurred in 19 patients (2.9%), 0.9% requiring a reintervention. Severe pain was reported by 9 patients (1.4%); fecal impaction occurred in 3 cases (0.5%) and suture disruption in 2 patients (0.3%). In 74 patients (11.6%), bladder catheterization was needed due to urinary retention. Of 550 patients who had a minimum follow-up of 3 years and were sent a postal questionnaire, 374 patients responded, with a median 7.3-year follow- up; 176 patients (32%) were lost to follow-up. Eleven patients (2.9% of 374 cases) reported pain during defecation, 6 (1.6%) developed skin tags or recurrence, 3 (0.8%) reported gas incontinence, 2 (0.5%) developed anal fistula and 1 (0.3%) had anal stricture. Submucosal reconstructive hemorrhoidectomy according to Parks still represents a good choice for the treatment of high-degree hemorrhoids with prolapse of the dentate line outside the anus and external circumferential hemorrhoids.

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.

Successful treatment of severe pouchitis with rebamipide refractory to antibiotics and corticosteroids: A case report

The antibiotics, metronidazole and ciprofloxacin, are the first-line treatment for pouchitis. Patients who do not respond to antibiotics or conventional medications represent a major challenge to therapy. In this report, we have described a successful treatment of severe refractory pouchitis with a novel agent, rebamipide, known to promote epithelial cell regeneration and angiogenesis. A 27-year-old male with ileo-anal pouch surgery presented with worsening anal pain, diarrhea, and abdominal pain. The patient was diagnosed to have pouchitis and was given metronidazole together with betamethasone enema (3.95 mg/dose). However, despite this intensive therapy, the patient did not improve. On endoscopy, ulceration and inflammation were seen in the ileal pouch together with contact bleeding and mucous discharge. The patient was treated with rebamipide enema (150 mg/dose) twice a day for 8 wk without additional drug therapy. Two weeks after the rebamipide therapy, stool frequency started to decrease and fecal hemoglobin became negative at the 4th wk. At the end of the therapy, endoscopy revealed that ulcers in the ileal pouch had healed with no obvious inflammation. The effect of rebamipide enema was dramatic and was maintained throughout the 11-mo follow-up. The patient continued to be in remission. No adverse effects were observed during the treatment or the follow-up period. The sustained response seen in this case with severe and refractory pouchitis indicates that agents, which promote epithelial cell growth, angiogenesis and mucosal tissue regeneration, are potential therapeutic agents for the treatment of refractory colorectal lesions.

Anal fissure is a common benign condition. An anorectal problem is defined as a split in the anal canal mucosa that extends from the dentate line to the anal verge. Chronic anal fissure is defined by a history of symptoms present for more than 2 months' duration and with a triad of external skin tags, namely, a hypertrophied anal papilla, an ulcer with rolled edges, and a base exposing the internal sphincter. Because complications such as incontinence are associated with surgical treatment, chemical sphincterotomy is currently favored. The objective of this study is to compare the difference in outcome between open partial lateral anal sphincterotomy and application of topical 0.2% nitroglycerin ointment for the treatment of chronic anal fissure. This was a quasi-experimental study carried out between January 16, 2007 and January 15, 2008 in the Surgical Department of Jinnah Hospital, Lahore, Pakistan. Sixty consecutive cases with a clinical diagnosis of chronic anal fissure were recruited in the study. All recruited patients met the study inclusion criteria and were randomly assigned to one of the two groups. Group A was managed conservatively using topical 0.2% nitroglycerin ointment, whereas Group B underwent open partial lateral anal sphincterotomy. Both groups were followed up at 1 week, 2 weeks, 4 weeks, and 6 weeks after the treatment. All the patients complained of pain. A total of 43 (71.7%) patients had pain with constipation, whereas 31 (51.7%) patients had bleeding per rectum. Upon clinically examining the anal area, tenderness was elicited in all 60 (100%) patients. Group A included 30 (11 females and 19 males) cases treated with topical 0.2% nitroglycerin ointment and Group B included 30 (11 females and 19 males) cases who underwent open partial lateral anal sphincterotomy. In Group A, only 15 patients with fissures were successfully treated (50%). By contrast, 28 (93%) patients with fissures in Group B were successfully treated, and only two (7%) remained uncured. These two patients (6.6%) in Group B suffered from incontinence due to flatus and feces as a complication of the procedure. This quasi-experimental study demonstrates that open partial lateral internal sphincterotomy is superior to topical 0.2% nitroglycerin application in the treatment of chronic anal fissure, with good symptomatic relief, high rate of healing, fewer side effects, and a very low rate of early continence disturbances.

Allium ampeloprasum subsp iranicum (Leek) has been traditionally used in antihemorrhoidal topical herbal formulations. This study aimed to evaluate its safety and efficacy in a pilot randomized controlled clinical trial. Twenty patients with symptomatic hemorrhoids were randomly allocated to receive the topical leek extract cream or standard antihemorrhoid cream for 3 weeks. The patients were evaluated before and after the intervention in terms of pain, defecation discomfort, bleeding severity, anal itching severity, and reported adverse events. A significant decrease was observed in the grade of bleeding severity and defecation discomfort in both the leek and antihemorrhoid cream groups after the intervention, while no significant change was observed in pain scores. There was no significant difference between the leek and antihemorrhoid cream groups with regard to mean changes in outcome measures. This pilot study showed that the topical use of leek cream can be as effective as a standard antihemorrhoid cream. © The Author(s) 2015.

Chronic proctalgia and chronic pelvic pain syndromes: New etiologic insights and treatment options

Chiarioni, Giuseppe; Asteria, Corrado; Whitehead, William E

2011-01-01

This systematic review addresses the pathophysiology, diagnostic evaluation, and treatment of several chronic pain syndromes affecting the pelvic organs: chronic proctalgia, coccygodynia, pudendal neuralgia, and chronic pelvic pain. Chronic or recurrent pain in the anal canal, rectum, or other pelvic organs occurs in 7% to 24% of the population and is associated with impaired quality of life and high health care costs. However, these pain syndromes are poorly understood, with little research evidence available to guide their diagnosis and treatment. This situation appears to be changing: A recently published large randomized, controlled trial by our group comparing biofeedback, electrogalvanic stimulation, and massage for the treatment of chronic proctalgia has shown success rates of 85% for biofeedback when patients are selected based on physical examination evidence of tenderness in response to traction on the levator ani muscle-a physical sign suggestive of striated muscle tension. Excessive tension (spasm) in the striated muscles of the pelvic floor appears to be common to most of the pelvic pain syndromes. This suggests the possibility that similar approaches to diagnostic assessment and treatment may improve outcomes in other pelvic pain disorders. PMID:22110274

Hemorrhoids: From basic pathophysiology to clinical management

PubMed Central

Lohsiriwat, Varut

2012-01-01

This review discusses the pathophysiology, epidemiology, risk factors, classification, clinical evaluation, and current non-operative and operative treatment of hemorrhoids. Hemorrhoids are defined as the symptomatic enlargement and distal displacement of the normal anal cushions. The most common symptom of hemorrhoids is rectal bleeding associated with bowel movement. The abnormal dilatation and distortion of the vascular channel, together with destructive changes in the supporting connective tissue within the anal cushion, is a paramount finding of hemorrhoids. It appears that the dysregulation of the vascular tone and vascular hyperplasia might play an important role in hemorrhoidal development, and could be a potential target for medical treatment. In most instances, hemorrhoids are treated conservatively, using many methods such as lifestyle modification, fiber supplement, suppository-delivered anti-inflammatory drugs, and administration of venotonic drugs. Non-operative approaches include sclerotherapy and, preferably, rubber band ligation. An operation is indicated when non-operative approaches have failed or complications have occurred. Several surgical approaches for treating hemorrhoids have been introduced including hemorrhoidectomy and stapled hemorrhoidopexy, but postoperative pain is invariable. Some of the surgical treatments potentially cause appreciable morbidity such as anal stricture and incontinence. The applications and outcomes of each treatment are thoroughly discussed.

Little is known about painful receptive anal intercourse (RAI) and its relationship to HIV risk and protective behaviors among men who have sex with men (MSM). The purpose of this study was to identify attributions for and responses to painful RAI among Black MSM in South African townships. In-depth interviews were conducted with 81 Black MSM (ages 20–39 years) who were purposively recruited from four townships. The semi-structured interviews addressed sexual behavior and identity, alcohol use, and safer sex. Pain during RAI was brought up by many participants without specific prompting from the interviewer. Analysis of the interview transcripts revealed that pain was a common feature of first RAI experiences but was not limited to first-time experiences. The participants attributed pain during RAI to partner characteristics, interpersonal dynamics, lack of lubricant, and alcohol use or non-use. The main strategies participants used to address pain during RAI were setting sexual boundaries and lubricant use; a small number of participants reported purposefully consuming alcohol to prevent the pain associated with RAI. Black South African MSM can be supported to reduce pain during RAI in ways that reduce their HIV/STI risk. Culturally-specific sexual health education, supportive sexual health services, and improved access to condom-compatible lubricants are important components of HIV/STI interventions for this population.

The purpose of this study was to evaluate the value of Chinese herbal fumigation in the postoperative anal disease. The authors randomly divided 348 patients into treatment group and control group with 174 cases in each group. The treatment group was given to the Chinese herbal medicine hemorrhoids lotion for fumigation based on conventional anti infective therapy, routine dressing change and relaxing bowel. The control group was given to 1 000 mL 1: 5 000 potassium permanganate solution for sitz bath, fumigation based on conventional anti infective therapy, routine dressing change and relaxing bowel. The pain score, edema score, bleeding score, granulation tissue growth score and wound healing time of two groups were compared after operation. The results showed that the postoperative 6 h pain scores were higher in the two groups, the postoperative 3,5,7 d pain scores gradually decreased, the difference was statistically significant (P < 0.05). The difference of postoperative 6 h pain scores was no significant difference between the two groups, while postoperative 3,5,7 d pain scores in the treatment group were significantly lower than those in the control group (P < 0.05). 7 days after operation, anal margin of edema score and blood in the stool score in the treatment group were lower than those in control group, meat medicine growth score was higher than that of the control group, the difference had statistical meaning (P < 0.05). The healing time of two groups was respectively (13.89 + 2.78), (18.45 + 1.65) d (P < 0.05). This study suggested that Chinese herbal fumigation and washing could reduce the pain degree of patients, the anal margin of edema, and the blood in the stool, also could promote granulation tissue growth and shorten the time of wound healing, deserve the clinical expansion.

Photodynamic Therapy in Gynecologic Malignancies: A Review of the Roswell Park Cancer Institute Experience.

Photodynamic therapy (PDT) is a treatment modality used in the management of solid tumor malignancies that employs the use of a photosensitizing agent, a light source and oxygen in order to illicit a direct cytotoxic effect. Its use in gynecologic malignancies is somewhat novel and has been used for palliative and curative intent. At the Roswell Park Cancer Institute, the use of PDT in the management of gynecologic cancers began in the mid 1980s and since that time 35 patients have received PDT as a treatment for recurrent or metastatic cutaneous and vulvar, vaginal, anal, and cervical recurrences. In our experience, 85% patients with metastatic cutaneous lesions had a complete response. Twenty-seven percent of patients with metastatic vaginal, cervical or anal recurrences had a complete response to therapy with a median response time of 28 months. Side effects from the treatment included moderate to severe burning sensation, pain and edema at the treatment site requiring narcotic pain medication for symptom management in patients who underwent treatment to cutaneous lesions as well as lower genital tract recurrences. PDT should be considered an option in patients who are too frail to undergo the standard of care or decline the standard of care in lieu of a less invasive treatment modality.

To compare the efficacy of homemade anal cushion suspension clamp combined with harmonic scalpel (ACS) and Milligan-Morgan hemorrhoidectomy combined with electric knife (MMH) in the treatment of stages III to IV hemorrhoids. We conducted a retrospective study of 99 patients with stages III to IV hemorrhoids hospitalized from January to December in 2013. Among them, 51 patients were treated with ACS, while 48 patients received MMH. Data from clinical recording and follow-up included operative time, intraoperative blood loss, hospitalization information, postoperative pain, and postoperative complications. Operative time, intraoperative blood loss and hospitalization time in ACS group were significantly less than those in MMH group (P < .05). Compared with MMH group, ACS group had a lower postoperative static pain score from days 1 to 14 (P < .01). The patients in ACS group exhibited less postoperative defecation pain scores from days 3 to 20 than those of MMH group (P < .05). The incidence of postoperative anal edema and delayed wound healing in ACS group was lower than that in MMH group (P < .05). Compared with MMH, our novel technique ACS was more effective and had fewer postoperative complications in the treatment of stages III to IV hemorrhoids.

Conservative treatment is the first line of treatment for anal fissure. The current study aimed to evaluate the impact of symptom duration on the response of anal fissure to conservative treatment. This prospective study was conducted on sixty patients with acute or chronic anal fissure who were treated conservatively with bulking agents, Sitz baths, and topical glyceryl trinitrate (GTN) 0.2%. Pain and constipation were assessed prior to treatment and at 6 weeks after therapy using visual analogue scale (VAS) and Wexner constipation score. Adverse effects as headache and postural hypotension were also queried. The mean pre-treatment VAS for acute fissure was significantly higher than chronic fissure (8.8 ± 0.96 Vs 5.8 ± 1.12), also the post-treatment VAS for acute fissure was significantly lower at 6 weeks of treatment (0.47 ± 0.8 Vs 2.5 ± 1.3). The baseline Wexner constipation score was comparable in both groups; however, at six weeks of treatment it declined more significantly in patients with acute fissure. Patients with acute fissure achieved significantly better healing than chronic fissure (80% Vs 40%). Healing rates decreased from 100% in patients with symptoms < one month to 33.3% in patients with symptoms >6 months. Conservative treatment including topical GTN 0.2% significantly hastened healing and relieved pain and other symptoms of acute more than chronic anal fissure. Healing rates of anal fissure in response to conservative treatment showed remarkable decrease in proportion to the duration of complaint. Copyright © 2017 IJS Publishing Group Ltd.

Proctalgia fugax is a benign, self-limiting pain experienced in the perineum. It is common, but most sufferers do not seek medical advice. The aetiology is unclear, but a variation of irritable bowel syndrome, pelvic floor myalgia, and internal anal sphincter spasm have all been suggested. A careful history can elicit the characteristic history, and simple reassurance is often all that is necessary. For persistent symptoms, therapies that induce internal anal sphincter relaxation are of value.

Colorectal cancer (CRC) may have a negative impact on a person's quality of life. Psycho-educational interventions for patients with CRC are rarely studied. The purpose of this feasibility trial was to evaluate the effect of a psycho-educational programme (PEP) on the health-related quality of life (HRQL) of patients treated for CRC and anal cancer. Patients with CRC and anal cancer were randomly assigned to a PEP (n = 47) or standard treatment (n = 39). The PEP included informative lectures, discussion, and reflection. HRQL was evaluated using the SF-36 at baseline and 1, 6, and 12 months after the end of the PEP. Patients in the PEP group had significantly better Mental Health scores after 1 month and significantly better Bodily Pain scores after 6 months compared with patients who received standard care. The results of this study indicate that a PEP can have a short-term effect on the mental health and bodily pain of patients treated for CRC and anal cancer when comparing with a control group. The article discusses the methodological difficulties of evaluating an intervention such as this PEP in a clinical setting. Copyright © 2015. Published by Elsevier Ltd.

Tolerance of the anal canal tends to be ignored in patients with cervical cancer undergoing whole pelvic radiotherapy. However, patients with hemorrhoids may be troubled with low radiation dose. We tried to analyze the dose-volume statistics of the anal canal in patients undergoing whole pelvic radiotherapy. The records of 31 patients with cervical cancer who received definite or postoperative radiotherapy at one institution were reviewed. Acute anal symptoms, such as anal pain and bleeding, were evaluated from radiotherapy start to 1 month after radiotherapy completion. Various clinical and dosimetric factors were analyzed to characterize relations with acute anal complications. The anal verge was located an average of 1.2 cm (range -0.6~3.9) below the lower border of the ischial tuberosity and an average of 2.7 cm (range -0.6~5.7) behind the sacral promontory level. The presence of hemorrhoids before radiotherapy was found to be significantly associated with acute radiation-induced anal symptoms (p = 0.001), and the mean induction dose for anal symptoms was 36.9 Gy. No patient without hemorrhoids developed an anal symptom during radiotherapy. Dosimetric analyses of V30 and V40 showed marginal correlations with anal symptoms (p = 0.07). The present study suggests a relation between acute anal symptoms following radiotherapy and acute hemorrhoid aggravation. Furthermore, the location of the anal verge was found to be variable, and consequently doses administered to the anal canal also varied substantially. Our results caution careful radiation treatment planning for whole pelvic radiotherapy, and that proper clinical management be afforded patients with hemorrhoids during radiotherapy.

The role of the defaecating pouchogram in the assessment of evacuation difficulty after restorative proctocolectomy and pouch-anal anastomosis.

Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) is the most frequently performed operation for intractable ulcerative colitis (UC) and for many patients with familial adenomatous polyposis (FAP). It can be complicated by a functional evacuation difficulty, which is not well understood. We aimed to evaluate the role of defaecating pouchography in an attempt to assess the mechanism of evacuation difficulty in pouch patients. All RPC patients who had had a defaecating pouchogram for evacuation difficulty at one hospital between 2006 and 2014 were retrospectively reviewed. The findings and features were correlated with the symptoms. Demographic, clinical and radiological variables were analysed. Eighty-seven [55 (63%) female] patients aged 47.6 ± 12.5 years (mean standard ± SD) were identified. Thirty-five had a mechanical outlet obstruction and 52 had no identified mechanical cause to explain the evacuation difficulty. The mean age of these 52 [33 (63%) female] patients was 48.2 ± 13 years. Of these 52 patients, significantly more used anti-diarrhoeal medication (P = 0.029), complained of a high frequency of defaecation (P = 0.005), experienced a longer time to the initiation of defaecation (P = 0.049) and underwent pouchoscopy (P = 0.003). Biofeedback appeared to improve the symptoms in 7 of 16 patients with a nonmechanical defaecatory difficulty. The most common findings on defaecating pouchography included residual barium of more than 33% after an attempted evacuation (46%, n = 24), slow evacuation (35%, n = 18) and mucosal irregularity (33%, n = 17). Correlation between radiological features and symptoms showed a statistically significant relationship between straining, anal pain, incontinence and urgency with patterns of anismus or pelvic floor descent or weakness seen on the defaecating pouchogram. Symptoms of incomplete evacuation, difficulty in the initiation of defaecation, high defaecatory frequency and abdominal pain were not correlated with the radiological features of the pouchogram. Defaecating pouchography may be useful for identifying anismus and pelvic floor disorders in pouch patients who have symptoms of straining, anal pain or incontinence. In patients with a high frequency of defaecation and abdominal pain it does not provide clinically meaningful information. Patients who complain of straining, incontinence, anal pain or urgency and have anismus or pelvic floor disorders may benefit from behavioural therapy.

Anal fistula in association with chronic anal fissure (fissure-fistula) is infrequently described. Recognizing this association and managing both components may help prevent some treatment failures seen with chronic anal fissure. This study aims to report on the outcomes of 20 consecutive patients with fissure-fistula managed with fistulotomy and injection of botulinum A toxin. The study is a retrospective, observational study, assessing the success of symptom resolution following fistulotomy with botulinum A toxin, in patients identified as having a chronic anal fissure with associated anal fistula. The study included all patients with this condition treated with combination treatment by a single surgeon at a tertiary care hospital between January 2013 and January 2016. Twenty patients with fissure-fistula treated with fistulotomy and botulinum toxin A were identified. The median cohort age was 44 years (range 25-78), with a predominance of males (80%) and posterior fissure position (80%). The most common presenting symptoms were anal pain (70%), rectal bleeding (55%), anal discharge (35%) and anal pruritus (35%). Mean follow-up was 10.5 weeks and all patients who attended follow-up appointments reported resolution of symptoms. There were no cases of incontinence and none of the cohort required further surgical intervention for the condition. Chronic anal fissure with associated anal fistula can be successfully managed with fistulotomy and injection of botulinum toxin A. Further studies would be helpful in determining if recognition and management of the fistula component in isolation with fistulotomy is as effective as fistulotomy plus botulinum A toxin. © 2017 Royal Australasian College of Surgeons.

Haemorrhoidal disease is a frequent entity worldwide. The surgical management is indicated in third or fourth degree internal hemorrhoidal disease. The conventional hemorrhoidectomy has showed good results but the severe postoperative pain is an important complain. Currently diverse surgical alternatives have been described, mainly to avoid the postoperative pain that follows surgical hemorrhoidectomy. One of these new options is the stapled hemorrhoidectomy using the PPH stapler. This procedure may produce less postoperative pain, with a shorter inpatient stay and faster return to work. The aim of this paper is to analyze the results of using the Procedure for Prolapsed Hemorrhoids (PPH) as treatment in Hemorrhoidal Disease. This is an observational and descriptive study, where 17 patients underwent stapled hemorrhoidectomy with PPH procedure, between March 2000 and August 2003. 52.8% of this patients presented grade three internal hemorrhoids and 47.2% grade four; 52.9% presented mild postoperative pain; 41.2% moderate and 5.9% severe pain. In a short and median follow up, due to the persistence of hemorrhoidal disease symptoms two patients required surgical re-intervention. Two more patients presented incontinency. One patient presented stenosis in the line of staples treated satisfactory with an anal dilatation session. The use of PPH is a feasible and safe procedure and it could be a surgical alternative in the treatment of hemorrhoidal disease, even before than conventional hemorrhoidectomy.

Rubber band ligation of hemorrhoids: A guide for complications

Albuquerque, Andreia

2016-01-01

Rubber band ligation is one of the most important, cost-effective and commonly used treatments for internal hemorrhoids. Different technical approaches were developed mainly to improve efficacy and safety. The technique can be employed using an endoscope with forward-view or retroflexion or without an endoscope, using a suction elastic band ligator or a forceps ligator. Single or multiple ligations can be performed in a single session. Local anaesthetic after ligation can also be used to reduce the post-procedure pain. Mild bleeding, pain, vaso-vagal symptoms, slippage of bands, priapism, difficulty in urination, anal fissure, and chronic longitudinal ulcers are normally considered minor complications, more frequently encountered. Massive bleeding, thrombosed hemorrhoids, severe pain, urinary retention needing catheterization, pelvic sepsis and death are uncommon major complications. Mild pain after rubber band ligation is the most common complication with a high frequency in some studies. Secondary bleeding normally occurs 10 to 14 d after banding and patients taking anti-platelet and/or anti-coagulant medication have a higher risk, with some reports of massive life-threatening haemorrhage. Several infectious complications have also been reported including pelvic sepsis, Fournier’s gangrene, liver abscesses, tetanus and bacterial endocarditis. To date, seven deaths due to these infectious complications were described. Early recognition and immediate treatment of complications are fundamental for a favourable prognosis. PMID:27721924

Gastrointestinal infestation with the parasite Enterobius vermicularis is common in humans and is usually harmless. Anal pruritus is the most characteristic symptom, but the parasites can cause severe abdominal pain mimicking appendicitis. Early recognition can prevent an unnecessary appendectomy. A six-year-old girl reported to the accident and emergency department with pain in the lower right abdominal region. She was admitted and treated for suspected perforated appendix, following physical examination supplemented with an abdominal CT scan. After antibiotic treatment the symptoms disappeared as did the abscess, apart from a minor amount of residual infiltrate. She was then readmitted twice with recurrent abdominal pain without radiological evidence of an abdominal focus. We decided to conduct a diagnostic laparoscopy and an elective appendectomy à froid. During this procedure living worms were found in the appendix. Treatment with the anthelminthicum mebendazol was effective. Gastro-intestinal infestation with E. vermicularis is very common, especially in young children. This infestation is usually harmless, but can mimic appendicitis. This infestation is easily treatable with mebendazol.

Effect of acute acoustic stress on anorectal function sensation in healthy human.

Little is known about the effects of acute acoustic stress on anorectal function. To determine the effects of acute acoustic stress on anorectal function and sensation in healthy volunteers. Ten healthy volunteers (7 M, 3 F, mean age 34 +/- 3 years) underwent anorectal manometry, testing of rectal compliance and sensation using a barostat with and without acute noise stress on separate days. Rectal perception was assessed using an ascending method of limits protocol and a 5-point Likert scale. Arousal and anxiety status were evaluated using a visual analogue scale. Acoustic stress significantly increased anxiety score (P < 0.05). Rectal compliance was significantly decreased with acoustic stress compared with control P (P < 0.000001). In addition, less intraballoon volume was needed to induce the sensation of severe urgency with acoustic stress (P < 0.05). Acoustic stress had no effect on hemodynamic parameters, anal sphincter pressure, threshold for first sensation, sensation of stool, or pain. Acute acoustic stimulation increased anxiety scores, decreased rectal compliance, and enhanced perception of severe urgency to balloon distention but did not affect anal sphincter pressure in healthy volunteers. These results may offer insight into the pathogenesis of stress-in-induced diarrhoea and faecal urgency.

High-Resolution Anorectal Manometry - New Insights in the Diagnostic Assessment of Functional Anorectal Disorders.

PubMed

Heinrich, Henriette; Misselwitz, Benjamin

2018-04-01

Functional anorectal disorders such as faecal incontinence (FI), functional anorectal pain, and functional defecation disorders (FDD) are highly prevalent and represent a high socioeconomic burden. Several tests of anorectal function exist in this setting; however, high-resolution anorectal manometry (HR-ARM) is a new tool that depicts pressure all along the anal canal and can assess rectoanal coordination. HR-ARM is used in the diagnosis of FI and especially FDD although data in health is still sparse, and pressure phenomena seen during simulated defecation, such as dyssynergia, are highly prevalent in health.

Anal stenosis is a rare but serious complication of anorectal surgery, most commonly seen after hemorrhoidectomy. Anal stenosis represents a technical challenge in terms of surgical management. A Medline search of studies relevant to the management of anal stenosis was undertaken. The etiology, pathophysiology and classification of anal stenosis were reviewed. An overview of surgical and non-surgical therapeutic options was developed. Ninety percent of anal stenosis is caused by overzealous hemorrhoidectomy. Treatment, both medical and surgical, should be modulated based on stenosis severity. Mild stenosis can be managed conservatively with stool softeners or fiber supplements. Sphincterotomy may be quite adequate for a patient with a mild degree of narrowing. For more severe stenosis, a formal anoplasty should be performed to treat the loss of anal canal tissue. Anal stenosis may be anatomic or functional. Anal stricture is most often a preventable complication. Many techniques have been used for the treatment of anal stenosis with variable healing rates. It is extremely difficult to interpret the results of the various anaplastic procedures described in the literature as prospective trials have not been performed. However, almost any approach will at least improve patient symptoms. PMID:19399922

Regarding anoplasty for anal stenosis, it is not clear to what extent the final anal caliber should be targeted. The aim of this study was to investigate the results of diamond-flap anoplasty performed in a calibrated manner for the treatment of severe anal stenosis due to a previous hemorrhoidectomy. Prospectively prepared standard forms were evaluated retrospectively. Anoplasty with unilateral or bilateral diamond flaps was performed for moderate or severe anal stenosis, targeting a final anal caliber of 25 to 26 mm. The demographic characteristics, causes of anal stenosis, number of previous surgeries, anal stenosis staging (Milsom and Mazier), anal calibers (millimeter), the Cleveland Clinic Incontinence Score, and the modified obstructed defecation syndrome Longo score were recorded on pre-prepared standard forms, as well as postoperative complications and the time of return to work. From January 2011 to July 2013, 18 patients (12 males, 67%) with a median age of 39 years (range, 27-70) were treated. All of the patients had a history of previous hemorrhoidectomy. The number of previous corrective interventions was 2.1 ± 1.8 (range, 0-4), and 2 patients had a history of failed anoplasty. Five patients (28%) had moderate anal stenosis and 13 (72%) had severe anal stenosis. Preoperative, intraoperative, and 12-month postoperative anal calibration values were 9 ± 3 mm (range, 5-15), 25 ± 0.75 mm (range, 24-26), and 25 ± 1 mm (range, 23-27) (p < 0.0001, for immediate postoperative and 12-month postoperative anal calibers compared with the intraoperative). Preoperative and 12-month postoperative Cleveland Clinic Incontinence Scores were 0.83 ± 1.15 (range, 0-4) and 0.39 ± 0.70 (range, 0-2) (p = 1.0). The clinical success rate was 88.9%. No severe postoperative complications were observed. This study was limited because it was a single-armed, retrospective analysis of prospectively designed data. Diamond-flap anoplasty performed in a standardized and calibrated manner is a highly successful method for the treatment of anal stenosis caused by previous hemorrhoidectomy.

"I Want to Feel Like a Full Man": Conceptualizing Gay, Bisexual, and Heterosexual Men's Sexual Difficulties.

2018-01-01

Current understandings of sexual difficulties originate from a model that is based on the study of heterosexual men and women. Most research has focused on sexual difficulties experienced by heterosexual men incapable of engaging in vaginal penetration. To better understand men's perceptions and experiences of sexual difficulties, seven focus groups and 29 individual interviews were conducted with gay (n = 22), bisexual (n = 5), and heterosexual (n = 25) men. In addition, the extent to which difficulties reported by gay and bisexual men differ from heterosexual men was explored. Data were analyzed using thematic analysis applying an inductive approach. Two intercorrelated conceptualizations were identified: penis function (themes: medicalization, masculine identity, psychological consequences, coping mechanisms) and pain (themes: penile pain, pain during receptive anal sex). For the most part, gay, bisexual, and heterosexual men reported similar sexual difficulties; differences were evident regarding alternative masculinity, penis size competition, and pain during receptive anal sex. The results of this study demonstrate the complexity of men's sexual difficulties and the important role of sociocultural, interpersonal, and psychological factors. Limitations and suggested directions for future research are outlined.

Purpose: To evaluate the effect of Kutaja Pratisaraniya Kshara and Apamarga Pratisaraniya Kshara in the management of Ardra Arshas and to compare the effect of both the Groups. Method: Cases presenting with classical signs and symptoms of Ardra Arshas were selected and randomly allocated into two groups i.e. GroupA and GroupB. In GroupA Apamarga Pratisaraniya Kshara was applied and in GroupB Kutaja Pratisaraniya Kshara was applied. The signs and symptoms of Ardra Arshas i.e. bleeding per rectum, pain, defecation, tonicity of anal sphincter, sloughing of the pile mass and size of Arshas was assessed before and after the completion of treatment. Result: After the 30 days of treatment with Kutaja Pratisaraniya Kshara provided significant relief in pain by 100%, in bleeding by 97.61%, in defecation 100%, slough by 100%, in colour of pile mass by 98.33%. in tonicity of the anal canal by 95% and in size of pile mass by 98.33%, and no recurrence noticed. After the 30 days treatment with Apamarga Pratisaraniya Kshara provided significant relief in pain by 100%, in bleeding by 97.7%, in defecation 95.5, in slough by 100%, in colour of pile mass by 98.1%. in tonicity of the anal canal by 95.2% and in size of pile mass by 96.6% and no recurrence noticed. On the basis of comparison of the effects as mentioned above it can be said that the application of Kutaja Kshara provided better relief in pain, defecation, slough and size of the pile mass of the patients in comparison to Apamarga Kshara. Conclusion: Group B cases showed better improvement when compared to Group A However all 20 cases of Group A and 20 cases of Group B showed good results.

Management of rare, low anal anterior fistula exception to Goodsall's rule with Kṣārasūtra.

PubMed

Shindhe, Pradeep S

2014-01-01

Anal fistula (bhagandara) is a chronic inflammatory condition, a tubular structure opening in the ano-rectal canal at one end and surface of perineum/peri-anal skin on the other end. Typically, fistula has two openings, one internal and other external associated with chronic on/off pus discharge on/off pain, pruritis and sometimes passing of stool from external opening. This affects predominantly male patients due to various etiologies viz., repeated peri-anal infections, Crohn's disease, HIV infection, etc., Complex and atypical variety is encountered in very few patients, which require special treatment for cure. The condition poses difficulty for a surgeon in treating due to issues like patient hesitation, trouble in preparing kṣārasūtra, natural and routine infection with urine, stool etc., and dearth of surgical experts and technique. We would like to report a complex and atypical, single case of anterior, low anal fistula with tract reaching to median raphe of scrotum, which was managed successfully by limited application of kṣārasūtra.

Acute anal toxicity after whole pelvic radiotherapy in patients with asymptomatic haemorrhoids: identification of dosimetric and patient factors.

PubMed

Jang, H; Baek, J G; Yoo, S-J

2015-06-01

Patients with asymptomatic haemorrhoids are known to be less tolerant of radiation doses lower than known tolerance doses. In the present study, the authors sought to identify the risk factors of acute haemorrhoid aggravation after whole pelvic radiotherapy (WPRT). The records of 33 patients with cervical, rectal or prostate cancer with asymptomatic haemorrhoids, which were confirmed by colonoscopy before the start of radiotherapy (RT), were reviewed. Acute anal symptoms, such as anal pain and bleeding, were observed up to 1 month after RT completion. Dosimetric and patient factors were analysed, and subgroup analyses were performed. The median induction dose for acute anal symptoms was 34.1 Gy (range, 28.8-50.4 Gy). Post-operative treatment intent showed more acute anal toxicity of patient factors (p = 0.04). In subgroup analysis, post-operative treatment intent and concurrent chemoradiotherapy were found to be related to acute anal symptoms (p < 0.01). Of the dosimetric factors, V10 tended to be related to acute anal symptoms (p = 0.08). This study indicates that asymptomatic haemorrhoid may deteriorate after low-dose radiation and that patient factors, such as treatment intent and concurrent chemotherapy, probably influence anal toxicity. In patients with asymptomatic haemorrhoids, WPRT requires careful dosimetry and clinical attention. The tolerance of anal canal tends to be ignored in patients with pelvic cancer who are undergoing WPRT. However, patients with asymptomatic haemorrhoids may be troubled by low radiation doses, and further studies are required.

[Proctalgia Fugax--what's new over the last 100 years?].

PubMed

Amosi, Doron; Werbin, Nachum; Skornick, Yehuda; Greenberg, Ron

2004-05-01

Proctalgia Fugax is a benign, self-limiting disease characterized by episodes of intense pain in the anorectal area occurring at infrequent intervals. It is common, but most suffers do not seek medical advice. Although its classical symptomatology was describe more than a century ago, the etiology is unclear. Theories regarding the etiology have centered on alteration in the internal anal sphincter function and morphology. For most patients after gathering a detailed history, reassurance and warm baths will suffice. In persistent cases therapies that induce internal anal sphincter relaxation are the main treatment modalities.

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.

The objective of this study was to evaluate the efficacy of transcutaneous electrical posterior tibial nerve stimulation in treatment of patients with chronic anal fissure and to compare it with the conventional lateral internal sphincterotomy. Consecutive patients with chronic anal fissure were randomly allocated into two treatment groups: transcutaneous electrical posterior tibial nerve stimulation group and lateral internal sphincterotomy group. The primary outcome measures were number of patients with clinical improvement and healed fissure. Secondary outcome measures were complications, VAS pain scores, Wexner's constipation and Peascatori anal incontinence scores, anorectal manometry, and quality of life index. Seventy-three patients were randomized into two groups of 36 patients who were subjected to transcutaneous electrical nerve stimulation and 37 patients who underwent lateral internal sphincterotomy. All (100%) patients in lateral internal sphincterotomy group had clinical improvement at one month following the procedure in contrast to 27 (75%) patients in transcutaneous electrical nerve stimulation group. Recurrence of anal fissure after one year was reported in one (2.7%) and 11 (40.7%) patients in lateral internal sphincterotomy and transcutaneous electrical nerve stimulation groups respectively. Resting anal pressure and functional anal canal length were significantly reduced after lateral internal sphincterotomy. Transcutaneous electrical posterior tibial nerve stimulation for treatment of chronic anal fissure is a novel, non-invasive procedure and has no complications. However, given the higher rate of clinical improvement and fissure healing and the lower rate of fissure recurrence, lateral internal sphincterotomy remains the gold standard for treating chronic anal fissure.

El-Khawand, Dominique; Wehbe, Salim; Whitmore, Kristene

2013-07-01

Botulinum toxin has recently been approved by the Food and Drug Administration (FDA) for the treatment of urinary incontinence associated with neurogenic detrusor overactivity. However, it has also been used off-label for a multitude of other conditions in the female pelvis, including urological, gynecological, and colorectal. This article reviews the most recent data regarding its efficacy and safety, and administration techniques for those conditions. A literature review of the most relevant reports published between 1985 and 2012. Urinary incontinence related to neurogenic detrusor overactivity is currently the only approved indication in the female pelvis. Other supported off-label uses include: idiopathic detrusor overactivity, interstitial cystitis/bladder pain syndrome, detrusor sphincter dyssynergia, high-tone pelvic floor dysfunction, anal fissure, anismus, and functional anal pain. Botulinum toxin may effectively and safely be used in many conditions of the female pelvis. More high quality research is needed to better clarify its role in the therapeutic algorithm for those indications.

Stapled haemorrhoidectomy in the operative treatment of grade III and IV haemorrhoids.

Stapled haemorrhoidectomy (SH) is a minimally invasive intervention that uses a stapling device which avoids the need for wounds in the sensitive anal area and reduces the pain after surgery. This study was undertaken in Nepal Medical College Teaching Hospital from January 2010 to December 2012 to evaluate the efficacy of this modality of treatment among patients (32) who presented in the Surgery OPD with grade III and grade IV haemorrhoids. The results of SH were evaluated by the relief of symptoms, severity of post operative pain, and complications of SH. Twenty five (78.1%) patients had grade III and 7 (21.9%) presented with grade IV hemorrhoids. The most frequent presentation reported in our study was bleeding per rectum with perianal prolapse. Mean operating time was 40-60 minutes whereas mean hospital stay was 1.9 days. Urinary retention was the most common complication found in 12 (37.5%) patients in the immediate post operative period. SH is a safe, rapid, and convenient surgical remedy for grade III and grade IV hemorrhoids with low rate of complications, minimal postoperative pain, and shorter hospital stay.

[Applicability of 3/4D transperineal ultrasound for the diagnosis of anal sphincter injury during the immediate pospartum].

García-Mejido, José Antonio; Gutiérrez Palomino, Laura; Fernández Palacín, Ana; Sainz-Bueno, José Antonio

The most common cause of anal sphincter injuries in women is vaginal birth. Endo-anal ultrasound is currently used for the diagnosis of anal sphincter defect. However, due to the inconvenience caused, it is not an applicable technique during the immediate post-partum. The aim of this study was to determine whether transperineal ultrasound in 3/4D is a useful diagnostic method for the assessment of anal sphincter during the immediate post-partum. A prospective study was conducted on the vaginal deliveries performed between September 2012 and June 2013 in the Valme University Hospital (Seville). Obstetric and foetal parameters that could influence the onset of perineal tears were studied. The patients underwent a transperineal 3/4D ultrasound and a multislice study (48hours after birth). The study included 146 puerperal women. The sphincter complex was assessed in all of them during the immediate post-partum. External anal injuries were observed in 10.3% of the cases. In 8.2% of cases, the primary suture of the external anal sphincter was detected during ultrasound examination, and 2.1% of asymptomatic lesions were diagnosed only with post-partum ultrasound. None of the patients reported discomfort or pain. The 3-dimensional transperineal ultrasound is helpful in determining the primary repair of the anal sphincter during the immediate post-partum, with no discomfort for patients, as well as for establishing those early sphincter injuries that go unnoticed during vaginal delivery.

Colonic motility in proctalgia fugax.

PubMed

Harvey, R F

1979-10-06

Intraluminal pressure recordings were obtained from the rectum and sigmoid colon in two patients experiencing attacks of proctalgia fugax. In each patient the pain appeared to result from contractions of the sigmoid colon, and not from spasm of the levator ani, rectal wall muscle, or anal sphincters, all of which have previously been suggested as the source of such pain. Proctalgia fugax therefore appears, at least in some patients, to be an unusual variant of the irritable bowel syndrome, in which pain is referred from the sigmoid colon to the rectum.

The Study of the Prevention of Anal Cancer (SPANC): design and methods of a three-year prospective cohort study

PubMed Central

2013-01-01

Background The incidence of human papillomavirus (HPV)-associated anal cancer is increasing in men who have sex with men (MSM). Screening for the presumed cancer precursor, high-grade anal squamous intraepithelial lesions (HSIL) in a manner analogous to cervical cancer screening has been proposed. Uncertainty remains regarding anal HPV natural history and the role of anal cytology and high-resolution anoscopy (HRA) as screening tests. Well-designed cohort studies are required to address these issues. Methods/design The SPANC study is a prospective study of the epidemiology of low-risk and high-risk anal HPV infection and related cytological and histological abnormalities in HIV-negative and HIV-positive homosexual men aged 35 years and over. The study aims to recruit 600 men from community-based settings in Sydney, Australia. There are six study visits over three years. At the first five visits men undergo a digital ano-rectal examination (DARE), an anal “Papanicolaou” (Pap) test for HPV detection, genotyping and anal cytology, followed by HRA and directed biopsy of any visible abnormalities. The men also complete a behavioural questionnaire before each visit. Questions include a detailed history of sexual behaviour, of anal symptoms, possible anal cancer risk factors and validated quality of life and psychosocial questions. Questionnaires are also completed 2 weeks and 3 months following the provision of test results and include questions on participant experience during the procedure and post-procedure symptoms, including pain and bleeding in addition to quality of life/ psychosocial outcomes. Discussion Recruitment for the study began in September 2010 and will conclude in mid-2015, with follow up continuing to 2018. Thus far, over 350 men have been recruited from a variety of community-based settings and are broadly representative of the target screening population. The SPANC study is one of only a small number of cohort studies globally to perform HPV, cytology and HRA screening on all participants over multiple time points. The study results will contribute to understanding of the natural history of anal HPV and inform the possible development of guidelines for implementing anal cancer screening programs in this population.

After haemorrhoidectomy the maximum resting pressure (MRP) of the anal canal is significantly increased. This increase play an important role in the making of postoperative pain. Recently, both the topical application of glyceryl trinitrate (GT) and the intrasphincter injection of botulinum toxin (Tox), resulted effective, in reducing temporary the MRP although with different mechanism of action. In this study the effectiveness and safe of contemporary injection of Tox and topical application of 300 mg/die of GT after Milligan-Morgan haemorrhoidectomy, were evaluated. Ten patients, undergoing Milligan-Morgan haemorrhoidectomy for 3rd and 4th degree haemorrhoids are included in this study. In all subjects, preoperatively and after 5 and 40 day following surgery, an ano-rectal manometry was performed. At the end of surgery, in all patients, 0.4 ml of solution containing 20UI of Tox was injected and 100 mg of 0.2% of GT was applied in the anal canal and in the perianal wounds. Afterwards the patients has been instructed to apply 100 mg of GT three times daily, for seven days. Time of perianal wounds healing, of first defecation, to return to work, of duration of surgery, of hospital stay, the complications, postoperative pain either on resting or during defecation, the analgesic consumption and side effects were recordered. On the 5th and 40th postoperative day, the MRP resulted significantly reduced as compared to preoperative values. Postoperative pain either on resting or during defecation was higher on the 1st assessment, afterwards it progressively decreased. Anal incontinence was observed only in two patients, whereas headache only in one case. The contemporary intrasphincter injection of Tox and perianal application of 300 mg/die of GT is safe and effective, with an incidence of complications similar to those detected when this drugs are given alone.

Argon plasma coagulation treatment of anal high-grade squamous intraepithelial lesions in men who have sex with men living with HIV: results of a 2-year prospective pilot study.

Men who have sex with men (MSM) living with HIV are at high risk for anal high-grade squamous intraepithelial lesions (HSILs) and cancer. The best management of anal HSIL remains unclear. Our objective was to assess whether argon plasma coagulation (APC) could be safe, well tolerated and efficient to treat anal HSILs in MSM living with HIV. A prospective phase II, open-label, pilot study was conducted to evaluate APC to treat anal HSILs in 20 HIV-positive MSM. Participants were followed for 2 years after their first treatment. Twenty men with persistent HSILs completed the 2-year study. Their baseline median CD4 count was 490 cells/μL and 85% had undetectable HIV viral loads. Overall, 65% (13/20) of participants were clear of HSILs at their 24-month visit. The initial response rates after the first, second and third APC treatments were 45%, 44% and 67%, respectively, but recurrences were common. The main side effect was pain during and within 1 week after the treatments. There were no long-term side effects, nor serious adverse events related to the procedure. Cost is a drawback. APC can be used to treat anal HSILs in HIV-seropositive MSM, and requires repeated treatment because of a high recurrence rate. As successful treatment of human papillomavirus (HPV) infection or eradication of the anal transitional zone remains impossible, HSIL treatment is challenging and requires long-term follow-up. © 2017 British HIV Association.

Constipation is a common pediatric problem. Sometimes the hospitalization is necessary and in these patients the organic cause should be verified. The authors report their experience in the management of children with severe constipation. Anorectal manometry (ARM) was performed after a careful examination of perineum and bowel disimpaction. Once organic cause had be excluded, the patient got medical therapy. If recto-anal inhibitory reflex (RAIR) was absent, not collaborative patient or medical treatment failed, the child underwent contrast enema (CE) and rectal suction biopsies (RSB). Local anesthetics were used for anal fissures or internal anal sphincter (IAS) hypertonia. Anal malformations and Hirschsprung's disease (HD) were surgically treated. Posterior sagittal anorectoplasty was performed for anal malformations. In 5 years 98 children (63 males) were observed (mean age 6 years). 5 children were premature for gestational age, 4 presented failure to thrive, 5 anal malformations and 45 anal fissures. ARM was performed in 87 children and 74 of them showed normal RAIR. Hypertonia of the IAS was recorded in 38 patients. RAIR was absent/unclear in 13 patients. Follow-up revealed 6 patients (negative to ARM) with poor results without oral laxative. CE was performed in 19 children (2 positive cases) and RBS in 25 patients (2 cases of HD). Children with severe constipation must be carefully observed and studied because of not negligible incidence of organic cause. The first step in the management of these patients is the evacuation of the fecaloma.

To compare the clinical acceptability of micronized purified flavonoid fraction (MPFF) 1000 mg with MPFF 500 mg tablets, administered at the same daily dose in patients suffering non-complicated acute hemorrhoids. MPFF is an established treatment for hemorrhoidal disease. This was a double-blind, multi-center, randomized study. Patients took either MPFF 1000 mg or 500 mg tablets for 7 days (daily dose; 3 g over 4 days followed by 2 g over 3 days). Adverse events were recorded in a patient diary. On day 7, anal pain and bleeding were assessed (visual analog scale [VAS] and Dimitroulopoulos scale, respectively). Patients (162) were randomized to MPFF 1000 mg (79) and MPFF 500 mg (83). No serious adverse events (AEs) occurred; 10 emergent AEs were considered treatment-related (6 for MPFF 1000 mg and 4 for 500 mg). Both regimens were associated with significant reduction in anal pain (VAS); -2.37 cm MPFF 1000 mg (P < 0.001) and -2.17 cm 500 mg (P < 0.001), with a slight trend in favor of MPFF 1000 mg (mean global reduction -2.27 cm, P < 0.001). Bleeding improved significantly in both groups of patients, 56% of patients on MPFF 1000 mg versus 61% on MPFF 500 mg. Bleeding ceased after treatment in 47% patients on MPFF 1000 mg versus 54% on 500 mg. After 7 days of treatment with MPFF at the same daily dose, both regimens reduced anal pain and bleeding. MPFF 1000 mg had a comparable safety profile to MPFF 500 mg, with the advantage of fewer tablets. Key limitations: Safety study.

BACKGROUND Constipation is one of the most frequent cause of patient visits to pediatric gastroenterology clinics. Early diagnosis and treatment is important. There are few studies about clinical manifestations of constipation in children. We aimed to find the relative frequency of gastrointestinal manifestations of constipation among constipated children. METHODS This cross-sectional study was carried out on children aged < 18 years old with chronic functional constipation referred to Imam Reza Clinic of Shiraz University of Medical Sciences. Children with organic causes of chronic constipation were excluded from study. Rome III criteria were used for defining constipation. The duration of study was 1 year starting from September 2010. Abdominal pain, fecal mass, rectal bleeding, anorexia, fecal soiling, retentive posture, withholding behavior, anal fissure, and peri-anal erythema were recorded for each case based on history and physical examination. Data were analyzed using SPSS software, version 13.0 (Chicago, IL, USA). RESULTS Of 222 children with functional constipation, 124(55.9%) were girls and 98 (44.1%) were boys with a mean ± SD age of 5±3.12 years. The mean ± SD duration of constipation was 2.2±1.9 years. Large and hard stool was present in 93.7% of the patients. Painful defecation and withholding behavior were seen in 92.3% and 91.9% of the patients, respectively. Fecal impaction was more frequent among boys compared with girls (p<0.01). Fecal soiling was present in 40.8% of the boys and 28.2% of the girls (p=0.04). CONCLUSION Large and hard stool, painful defecation and withholding behavior were the most frequent signs or symptoms among children with chronic functional constipation. Fresh rectal bleeding and anal fissure were the least frequent signs and symptoms in this group. PMID:25628851

Objective The incidence of anal cancer is higher in women than men in the general population and has been increasing for several decades. Similar to cervical cancer, most anal cancers are associated with human papillomavirus (HPV) and it is believed that anal cancers are preceded by anal high-grade squamous intraepithelial lesions (HSIL). Our goal was to summarize the literature on anal cancer, HSIL and HPV infection in women, and provide screening recommendations in women. Methods A group of experts convened by the ASCCP and the International Anal Neoplasia Society reviewed the literature on anal HPV infection, anal SIL and anal cancer in women. Results Anal HPV infection is common in women but is relatively transient in most. The risk of anal HSIL and cancer varies considerably by risk group, with HIV-infected women and those with a history of lower genital tract neoplasia (LGTN) at highest risk compared with the general population. Conclusions While there are no data yet to demonstrate that identification and treatment of anal HSIL leads to reduced risk of anal cancer, women in groups at the highest risk should be queried for anal cancer symptoms and have digital anorectal examinations to detect anal cancers. HIV-infected women and women with LGTN, may be considered for screening with anal cytology with triage to treatment if HSIL is diagnosed. Healthy women with no known risk factors or anal cancer symptoms do not need to be routinely screened for anal cancer or anal HSIL. PMID:26103446

Anal fistula (AF) is a pathological connection between anus and skin in its surroundings. The main reason for the formation of anal fistula is a bacterial infection of the glands within the anal crypts. One of the modern techniques for the treatment of fistulas that do not interfere with the sphincters consists in implantation of a plug made from collagen material. We are presenting the first Polish experience with a new model of biomaterial plug for the treatment of anal fistula. We also point out key elements of the procedure (both preoperative and intraoperative) associated with this method. In the authors' opinion, the method is simple, safe and reproducible. Innovative shape of the plug minimizes the risk of its migration and rotation. It also perfectly blends with and adapts to the course and shape of the fistula canal, allowing it to become incorporated and overgrown with tissue in the fistula canal. The relatively short operation time, minor postoperative pain and faster convalescence are with no doubt additional advantages of the method. Long-term observation involving more patients is essential for evaluation of the efficacy of the treatment of fistulas with the new type of plug.

Sphincter trauma after anorectal surgery is usually asymptomatic. Frequency of trauma cannot be established with the clinical examination only. The frequency of operative sphincter defects and their correlation with disorders of continence was evaluated with the endoanal ultrasound. This study includes 123 subjects who had undergone anorectal surgery in the past and were examined with endoanal ultrasound for various indications such as continence disorders, recurrent fistula, idiopathic perineal pain, or simple postoperative follow-up. No subjects had isolated external anal sphincter defects. Nineteen of 123 patients (15%) had minor or major continence disorders, 55 patients (45%) had no sphincter defects, 42 (34%) had only internal anal sphincter (IAS) defects, and 26 (21%) had simultaneously external and internal anal sphincter (EAS) defects. The incidence of IAS and EAS trauma after Milligan-Morgan hemorrhoidectomy was 1/18 (5.5%) and 0/18 respectively; after fistula repair, 24/42 (57%) and 12/42 (29%); and after anal dilatation, 13/17 (76%) and 4/17 (24%). Sixteen of 26 patients (62%) with EAS trauma and 51/68 patients (75%) with IAS trauma did not report any disorders of continence. In patients with two or more operations, the frequency of IAS trauma was 74%, 30% for EAS trauma, and 26% for continence disorders.

Circular stapled hemorrhoidopexy (CSH) is an effective technique for treating prolapsing hemorrhoids; but urgency and anal stenosis are common postoperative complications. The aim of this study was to assess the efficacy and postoperative outcomes of partial stapled hemorrhoidopexy (PSH), compared with CSH. Seventy-two consecutive patients with grade III and IV hemorrhoids who met the inclusion/exclusion criteria were divided in a non-randomized manner to undergo either PSH (n = 34) or CSH (n = 38). Intraoperative and postoperative parameters in both groups were collected and compared. The postoperative visual analog score for pain at first defecation was significantly lower in the PSH group than that in the CSH group (P = 0.001). Fewer patients in the PSH group experienced postoperative urgency, compared with those in the CSH group at 12 h, 1 day, and 7 days after surgery (P = 0.025, P = 0.019, and P = 0.043, respectively). Gas incontinence occurred in 3 patients (7.9%) in the CSH group, but in none of patients in the PSH group (P = 0.242). Postoperative anal stenosis developed in one patient (2.6%) in the CSH group, but in none of the patients in the PSH group (P = 1.0). The 2-year recurrence rate was 2.9 and 5.3%, respectively, in the PSH and CSH groups (P = 1.0). The 2-year recurrence rate is similar in patients with grade III-IV hemorrhoids treated with PSH or CSH. However, PSH is associated with less postoperative pain, fewer episodes of urgency, and no anal incontinence or anal stenosis.

A low temperature hollow microneedle system was devised to deliver sol-gel transition formulation near the surface of the skin for extended release and local delivery of drug by a non-invasive method. This new system can improve treatment of intermittent fecal incontinence. The low-temperature system was integrated with a hollow microneedle to maintain the low temperature of the sol formulation. Various sol-gel formulations using Pluronic F-127 (PF-127) and Hydroxy-propyl-methyl-cellulose (HPMC) were prepared, and their gelation temperature, flow property, and diffusion retardation were observed. Resting anal sphincter pressure in response to a phenylephrine (PE) sol-gel formulation was measured using an air-charged catheter. The biocompatibility of the sol-gel PE formulation was evaluated by observing the immunological response. When the PF-127 25%, HPMC 1% and PE formulation (PF25-HPMC1-PE) was injected through the peri-anal skin of the rat in vivo, the highest pressure on the anal sphincter muscle occurred at 6-8 h and anal pressure increased and lasted twice as long as with the phosphate-buffered saline (PBS)-PE formulation. There was no significant difference in the number of mast cells after administration into the rat in vivo between the PF25-HPMC1-PE formulation and the PBS-PE formulation. The combination of a low-pain hollow microneedle system and an injectable sol-gel formulation improved the efficacy of treatment of intermittent fecal incontinence. A low-temperature hollow microneedle system using a sol-gel formulation has many applications in medical treatments that require depot effect, local targeting, and pain control.

Chronic Constipation and Constipation-Predominant IBS: Separate and Distinct Disorders or a Spectrum of Disease?

2016-03-01

Rome III diagnostic criteria separate patients with idiopathic chronic constipation into mutually exclusive categories of constipation-predominant irritable bowel syndrome (IBS-C) or functional constipation (FC). However, several experts think that these conditions are not different disorders, but parts of a continuum. To shed light on this issue, we examined studies that compared IBS-C with FC with respect to symptoms, pathophysiologic mechanisms, and treatment response. When the Rome III requirement that patients meeting criteria for IBS cannot also be given a diagnosis of FC is suspended, most patients meet criteria for both, and, contrary to expectation, IBS-C patients have more symptoms of constipation than patients with FC. No symptoms reliably separate IBS-C from FC. Physiologic tests are not reliably associated with diagnosis, but visceral pain hypersensitivity tends to be more strongly associated with IBS-C than with FC, and delayed colonic transit tends to be more common in FC. Although some treatments are effective for both IBS-C and FC, such as prosecretory agents, other treatments are specific to IBS-C (eg, antidepressants, antispasmodics, cognitive behavior therapy) or FC (eg, prucalopride, biofeedback). Future studies should permit IBS-C and FC diagnoses to overlap. Physiologic tests comparing these disorders should include visceral pain sensitivity, colonic transit time, time to evacuate a water-filled balloon, and anal pressures or electromyographic activity from the anal canal. To date, differential responses to treatment provide the strongest evidence that IBS-C and FC may be different disorders, rather than parts of a spectrum.

To evaluate the application of anal endosonography in the morphology of internal anal sphincter (IAS), external anal sphincter (EAS) and puborectalis (PR) in order to provide necessary information for analysis of the etiology of fecal incontinence and formulation of the therapeutic schedule. From December 2010 to November 2012, 18 children of anorectal malformation (n=14) or Hirschsprung's disease(n=4) with fecal incontinence received anal endosonography. The morphology of IAS, EAS and PR was observed. The damage of anal sphincter was classified according to Starck criteria. Anorectal mamometry and anal clinical score were measured simultaneously. Spearman analysis was performed to examine the correlation of anal sphincter damage with anorectal mamometric score and anal clinical score. According to Starck criteria, anal sphincter damage was small in 11 children, moderate in 6, and severe in 1. PR damage was found in 4 cases. Starck score was positively correlated with manometric score(P<0.05), while not correlated with anal clinical score(P>0.05). Anal endosonography can clearly display the morphology of IAS, EAS and PR, and their integrity and damage degree. It is a very valuable technique to evaluate the anal sphincter of the children with fecal incontinence, which however can not reflect the function of anal sphincter and anal continence thoroughly.

The aim of the present study was to evaluate the safety and efficacy of autologous, micro-fragmented and minimally manipulated adipose tissue injection associated closure of the internal opening in promoting healing of complex anal fistula. A pilot study was conducted on patients referred to our center with anal fistula, from April 2015-December 2016. Inclusion criteria were age over 16 years old and a diagnosis of complex anal fistula according to the American Gastroenterological Association classification The patients were divided into 2 groups; the "first time group" (Group I) in which micro-fragmented adipose tissue injection with closure of the internal opening was the first sphincter-saving procedure, and the "recurrent group" (Group II) consisting of patients who had failed prior sphincter-saving procedures. The procedure was carried out 4-6 weeks after seton placement. Follow-up visits were scheduled at 7 days, and 1, 3, 6 and 12 months after surgery. Fistula healing was defined as the closure of the internal and external openings without any discharge. Out of 47 patients with complex transsphincteric anal fistula, 19 met the inclusion criteria and were selected to undergo the procedure. Twelve of these patients (Group I) had micro-fragmented adipose tissue injection as first-line treatment, and 7 (Group II) had failed previous sphincter-saving procedures. The mean operative time was 55 ± 6 min (range 50-70 min). The mean postoperative pain score measured with the visual analog pain scale was 2 ± 1.4 (range 0-4). No intraoperative difficulties related to the use of the kit were recorded. There were no cases of postoperative fever or abdominal sepsis related to the procedure and no post-treatment perianal bleeding or impaired anal continence. Only 3 cases of minor abdominal wall hematoma that did not require any treatment and 1 case of perianal abscess were observed. Patients were evaluated for a mean follow-up time of 9 ± 3.1 months (range 3-12 months). The overall healing rate was 73.7, 83.3% for Group I and 57.1% for Group II. The injection of autologous, micro-fragmented and minimally manipulated adipose tissue associated with closure of the internal opening is a safe, feasible and reproducible procedure and may enhance complex anal fistula healing.

The impact of anal incontinence on women's sexual function is poorly understood. The aim of this study was to investigate the relationship between anal incontinence and sexual activity and functioning in women. This is a cross-sectional study. This investigation was conducted in a community-based integrated health care delivery system. Included were 2269 ethnically diverse women aged 40 to 80 years. Self-administered questionnaires assessed accidental leakage of gas (flatal incontinence) and fluid/mucus/stool (fecal incontinence) in the past 3 months. Additional questionnaires assessed sexual activity, desire and satisfaction, as well as specific sexual problems (difficulty with arousal, lubrication, orgasm, or pain). Multivariable logistic regression models compared sexual function in women with 1) isolated flatal incontinence, 2) fecal incontinence (with or without flatal incontinence), and 3) no fecal/flatal incontinence, controlling for potential confounders. Twenty-four percent of women reported fecal incontinence and 43% reported isolated flatal incontinence in the previous 3 months. The majority were sexually active (62% of women without fecal/flatal incontinence, 66% with isolated flatal incontinence, and 60% with fecal incontinence; p = 0.06). In comparison with women without fecal/flatal incontinence, women with fecal incontinence were more likely to report low sexual desire (OR: 1.41 (CI: 1.10-1.82)), low sexual satisfaction (OR: 1.56 (CI: 1.14-2.12)), and limitation of sexual activity by physical health (OR: 1.65 (CI: 1.19-2.28)) after adjustment for confounders. Among sexually active women, women with fecal incontinence were more likely than women without fecal/flatal incontinence to report difficulties with lubrication (OR: 2.66 (CI: 1.76-4.00)), pain (OR: 2.44 (CI: 1.52-3.91)), and orgasm (OR: 1.68 (CI: 1.12-2.51)). Women with isolated flatal incontinence reported sexual functioning similar to women without fecal/flatal incontinence. The cross-sectional design prevented evaluation of causality. Although most women with fecal incontinence are at high risk for several aspects of sexual dysfunction, the presence of fecal incontinence does not prevent women from engaging in sexual activity. This indicates that sexual function is important to women with anal incontinence and should be prioritized during therapeutic management.

An Italian HIV-positive man having sex with men (MSM) attended the STIs Outpatients Clinic of Sant'Orsola Hospital in Bologna complaining of anal pain and constipation. According to patient's sexual history and repertoires, NAAT testing for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) was performed. Pharyngeal and anal swabs resulted positive for CT DNA detection and the following molecular genotyping identified a L2 serovar, coming to the final diagnosis of pharyngeal and rectal lymphogranuloma venereum (LGV) infection. After an antibiotic therapy with doxycycline 100 mg twice a day for 3 weeks, the patient completely recovered and the test of cure was negative for LGV infection.

Interpreting the significance of anal findings in child sexual abuse can be difficult. The aim of this study is to compare the frequency of anal features between children with and without anal penetration. This is a retrospective blinded review of consecutive charts of children seen for suspected sexual abuse at a regional referral center from January 1. 2005 to December 31. 2009 Based on predetermined criteria, children were classified into two groups: low or high probability of anal penetration. The charts of 1115 children were included, 84% girls and 16% boys with an age range from 0.17 to 18.83 years (mean 9.20 year). 198 children (17.8%) were classified as belonging to the anal penetration group. Bivariate analysis showed a significant positive association between the following features and anal penetration: Anal soiling (p=0.046), fissure (p=0.000), laceration (p=0.000) and total anal dilatation (p=0.000). Logistic regression analysis and stratification analysis confirmed a positive association of soiling, anal lacerations and anal fissures with anal penetration. Total anal dilation was significantly correlated with a history of anal penetration in girls, in children examined in the prone knee chest position and in children without anal symptoms. Several variables were found to be significantly associated with anal penetration, including the controversial finding of total anal dilatation. Due to limitations in the study design, this finding should still be interpreted with caution in the absence of a clear disclosure from the child. Copyright © 2013 Elsevier Ltd. All rights reserved.

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.

Abstract To compare the efficacy of homemade anal cushion suspension clamp combined with harmonic scalpel (ACS) and Milligan–Morgan hemorrhoidectomy combined with electric knife (MMH) in the treatment of stages III to IV hemorrhoids. We conducted a retrospective study of 99 patients with stages III to IV hemorrhoids hospitalized from January to December in 2013. Among them, 51 patients were treated with ACS, while 48 patients received MMH. Data from clinical recording and follow-up included operative time, intraoperative blood loss, hospitalization information, postoperative pain, and postoperative complications. Operative time, intraoperative blood loss and hospitalization time in ACS group were significantly less than those in MMH group (P < .05). Compared with MMH group, ACS group had a lower postoperative static pain score from days 1 to 14 (P < .01). The patients in ACS group exhibited less postoperative defecation pain scores from days 3 to 20 than those of MMH group (P < .05). The incidence of postoperative anal edema and delayed wound healing in ACS group was lower than that in MMH group (P < .05). Compared with MMH, our novel technique ACS was more effective and had fewer postoperative complications in the treatment of stages III to IV hemorrhoids. PMID:28658138

Fissure in ano is one of the commonest benign and painful proctologic diseases causing considerable morbidity and reduction in quality of life. There are medical as well as surgical treatment options for anal fissure. The study was conducted to compare the frequency of postoperative faecal incontinence in patients with closed lateral internal anal sphincterotomy with von-greaves knife versus standard Park's operation (open method) for chronic anal fissure. This was a randomized controlled trial (RCT) was conducted at the Department of Surgery, KVSS, S.I.T.E. Hospital, Karachi, for a period of six months from 13th February to 12th August 2011. Ninety four consecutive patients having chronic anal fissure were assigned through blocked randomization to groups A & B, with 47 patients in each group. Closed lateral internal anal sphincterotomy (CLIAS) via von-greaves knife was carried out in patients of group-A whereas patients of group-B were subjected to open internal anal sphincterotomy (OIAS) also known as Parks' procedure. Faecal incontinence was noted on the 5th post-operative day. Data was analysed using SPSS 16. There were 81 (86.2%) males and 13 (13.8%) females with male to female ratio being 6:1. Mean age was 38.38 mp ± 14.56 years. Post-operative faecal incontinence in patients undergoing CLIAS was 4.3% while it was 21.3% in those undergoing OIAS with a p-value of 0.027. CLIAS with von-greaves knife is effective in reducing faecal incontinence on 5th postoperative day as compared to standard OIAS. CLIAS with von-greaves knife is effective in reducing faecal incontinence on 5th postoperative day as compared to OIAS (Park's procedure). Therefore, this technique may be used in future regularly to treat chronic anal fissure for prevention of this morbidity.

Anal cytology may be useful for evaluating lesions associated with human papillomavirus (HPV) in individuals at increased risk for anal cancer. Liquid-based cytology was used to assess anal cytological lesions among human immunodeficiency virus (HIV)-infected and HIV-uninfected men who have sex with men (MSM). The Linear Array HPV genotyping test was used for HPV detection. This cross-sectional study included 1021 MSM, of whom 388 were HIV-infected (38.0%). Anal cytological lesions (atypical squamous cells of undetermined significance or more severe [ASCUS+]) were observed in 32.5% and 53.2% of the HIV-uninfected and HIV-infected individuals, respectively (P < .0001). The highest ASCUS + prevalence was observed among ≥45-year-old HIV-uninfected MSM (37.3%) and 25-to 29-year-old HIV-infected MSM (66.7%). High-grade squamous intraepithelial lesions (HSILs) peaked in ≥ 45-year-old HIV-uninfected subjects and 35- to 39-year-old HIV-infected subjects. Individuals with anal infections with high-risk (HR) HPV types were 3 to 4 times more likely to have an ASCUS + report. An HPV-16 and/or HPV-18 infection increased the odds of HSIL or more severe cytology (HSIL+) for HIV-infected MSM almost 4 times. MSM concurrently infected with HR and low-risk HPVs were significantly more likely to have low-grade squamous intraepithelial lesions or more severe cytology (LSIL+) than those infected with only HR types. No significant associations were found between cytological abnormalities and the HIV load and nadir and current CD4 + counts. The prevalence of anal cytological lesions is high in MSM, even in HIV-infected individuals treated with combined antiretroviral therapy. In these subjects, HSILs occur more frequently and at a younger age in comparison with HIV-uninfected counterparts. Specific diagnostic procedures should be implemented to manage individuals at increased risk for anal cancer with an abnormal anal Papanicolaou test.

AIM: To compare the effects and postoperative complications between tissue selecting therapy stapler (TST) and Milligan-Morgan hemorrhoidectomy (M-M). METHODS: Four hundred and eighty patients with severe prolapsing hemorrhoids, who were admitted to the Shenyang Coloproctology Hospital between 2009 and 2012, were randomly divided into observation (n = 240) and control (n = 240) groups. Hemorrhoidectomies were performed with TST in the observation group and with the M-M technique in the control group. The therapeutic effects, operation security, and postoperative complications in the two groups were compared. The immediate and long-term complications were assessed according to corresponding criteria. Pain was assessed on a visual analogue scale. The efficacy was assessed by specialized criteria. The follow-up was conducted one year after the operation. RESULTS: The total effective rates of the observation and control groups were 99.5% (217/218) and 98.6% (218/221) respectively; the difference was not statistically significant (P = 0.322). Their were significant differences between observation and control groups in intraoperative blood loss (5.07 ± 1.14 vs 2.45 ± 0.57, P = 0.000), pain (12 h after the surgery: 5.08 ± 1.62 vs 7.19 ± 2.01, P = 0.000; at first dressing change: 2.64 ± 0.87 vs 4.34 ± 1.15, P = 0.000; first defecation: 3.91 ± 1.47 vs 5.63 ± 1.98, P = 0.001), urine retention (n = 22 vs n = 47, P = 0.001), anal pendant expansion after the surgery (2.35 ± 0.56 vs 5.16 ± 1.42, P = 0.000), operation time (18.3 ± 5.6 min vs 29.5 ± 8.2 min, P = 0.000), and the length of hospital stay (5.3 ± 0.6 d vs 11.4 ± 1.8 d, P = 0.000). Moreover TST showed significant reductions compared to M-M in the rates of long-term complications such as fecal incontinence (n = 3 vs n = 16, P = 0.003), difficult bowel movement (n = 1 vs n = 9, P = 0.011), intractable pain (n = 2 vs n = 12, P = 0.007), and anal discharge (n = 3 vs n = 23, P = 0.000). CONCLUSION: TST for severe prolapsing hemorrhoids is a satisfactory technique for more rapid recovery, lower complication rates, and higher operation security. PMID:25741159

To develop a framework that describes the most important symptom outcomes for anal incontinence treatment from the patient perspective. A conceptual framework was developed by the Pelvic Floor Disorders Network based on four semistructured focus groups and confirmed in two sets of 10 cognitive interviews including women with anal incontinence. We explored: 1) patient-preferred terminology for describing anal incontinence symptoms; 2) patient definitions of treatment "success"; 3) importance of symptoms and outcomes in the framework; and 4) conceptual gaps (defined as outcomes not previously identified as important). Sessions were conducted according to grounded theory transcribed, coded, and qualitatively and quantitatively analyzed to identify relevant themes. Content and face validity of the framework were further assessed using cognitive interviews. Thirty-four women participated in focus groups and 20 in cognitive interviews. Overall, 29 (54%) were aged 60 years or older, 42 (78%) were white, and 10 (19%) had a high school degree or less. Two overarching outcome themes were identified: "primary bowel leakage symptoms" and "ancillary bowel symptoms." Subdomains important in primary bowel leakage symptoms included leakage characteristics (symptom frequency, amount of leakage, symptom bother) and conditions when bowel leakage occurs (predictability, awareness, urgency). Subdomains important under ancillary bowel symptoms included emptying disorders (constipation, obstructed defecation, and wiping issues) and discomfort (pain, burning). New outcomes identified included predictability, awareness, wiping issues, and discomfort. Women with anal incontinence desire a wide range of symptom outcomes after treatment. These are captured in our conceptual framework, which can aid clinicians and researchers in assessing anal incontinence. LEVEL OF EVIEDENCE: II.

Purpose: To identify dosimetric parameters derived from anorectal, rectal, and anal wall dose distributions that correlate with different late gastrointestinal (GI) complications after three-dimensional conformal radiotherapy for prostate cancer. Methods and Materials: In this analysis, 641 patients from a randomized trial (68 Gy vs. 78 Gy) were included. Toxicity was scored with adapted Radiation Therapy Oncology Group/European Organization for the Research and Treatment of Cancer (RTOG/EORTC) criteria and five specific complications. The variables derived from dose-volume histogram of anorectal, rectal, and anal wall were as follows: % receiving {>=}5-70 Gy (V5-V70), maximum dose (D{sub max}), and mean dose (D{sub mean}).more » The anus was defined as the most caudal 3 cm of the anorectum. Statistics were done with multivariate Cox regression models. Median follow-up was 44 months. Results: Anal dosimetric variables were associated with RTOG/EORTC Grade {>=}2 (V5-V40, D{sub mean}) and incontinence (V5-V70, D{sub mean}). Bleeding correlated most strongly with anorectal V55-V65, and stool frequency with anorectal V40 and D{sub mean}. Use of steroids was weakly related to anal variables. No volume effect was seen for RTOG/EORTC Grade {>=}3 and pain/cramps/tenesmus. Conclusion: Different volume effects were found for various late GI complications. Therefore, to evaluate the risk of late GI toxicity, not only intermediate and high doses to the anorectal wall volume should be taken into account, but also the dose to the anal wall.« less

Flavonoids to reduce bleeding and pain after stapled hemorrhoidopexy: a randomized controlled trial.

Control of postoperative symptoms is of paramount importance in ambulatory surgery. This trial was conducted to evaluate whether a micronized purified flavonoid fraction (MPFF) (Detralex((R))) reduces postoperative bleeding, pain and consumption of analgesics after ambulatory stapled hemorrhoidopexy, as reported in trials after classic hemorrhoidectomy. Phlebotropic activity, protective effect on the capillaries and anti-inflammatory properties of this drug have been reported in several studies. Sixty-three patients with third-degree hemorrhoids had ambulatory stapled hemorrhoidopexy under spinal anesthesia in the period of one year. The patients were randomized, with 30 receiving Detralex 500 mg (2 tablets 3 times daily for 5 days after the operation) and 33 forming the control group. The patients were asked to daily self-assess the presence of blood on defecation, degree of pain and consumption of analgesics for the first week after the operation. There was no significant difference between the two groups in duration of presence of blood, degree of pain or analgesics requirement. No major complications, such as bleeding requiring transfusion or hospitalization, sepsis, anal stenosis or urgent defecation, were noted in the follow-up period. There were no side effects from Detralex treatment. In our study we could not demonstrate any positive effect of prescribing flavonoids after stapler hemorrhoidopexy. This procedure may not be sufficiently aggressive and is associated with too few postoperative complications to show any protective influence of flavonoids.

Proctalgia fugax is considered as intermittent anal pain of unknown etiology; a variety of treatments have been used, without, however, permanent results. Injection of botulinum A toxin is recently suggested as an alternative option. We present the case of a woman presenting proctalgia fugax that was untreatable through other current forms of treatment. After two administrations of botulinum A toxin, 80 units and 100 units each, the patient remained asymptomatic on 8-month follow-up control. Botulinum A toxin injection can reduce internal anal sphincter pressure, leading to relief of symptoms, and seems a promising option with minimal morbidity in cases on proctalgia fugax that does not respond to other current treatments.

Abstract Penile Mondor's disease is a rare condition characterized by sclerosing thrombophlebitis of the superficial dorsal penile vein. Usually its causes are benign, but it is also evident in cancer patients. We report the case of a 62-year-old man with a cT4 anal cancer (infiltration of corpora spongiosa and penile bulb), associated with extensive loco-regional lymphadenopathy, who developed painful lumps in the midline of the anterior penile surface while receiving radical chemoradiotherapy. Physical examination revealed two palpable cord-like swellings located 2 cm from the pubic symphysis. Color Doppler ultrasound established the diagnosis of Mondor's disease. The patient was successfully managed with non-steroidal anti-inflammatory drugs. The causative factors were pelvic malignancy and radiotherapy. The diagnosis was challenging since Mondor's disease is a rare condition and the differential diagnosis included malignancy progression. This is the first case report describing penile Mondor's disease in a patient with anal cancer under chemoradiotherapy. PMID:29383260

Anal sphincter fibrillation: is this a new finding that identifies resistant chronic anal fissures that respond to botulinum toxin?

PubMed

Moon, A; Chitsabesan, P; Plusa, S

2013-08-01

Anal fissures can be resistant to treatment and some patients may undergo several trials of medical therapy before definitive surgery. It would be useful to identify predictors of poor response to medical therapy. This study assesses the role of anorectal physiological criteria to identify patients with anal fissure predicted to fail botulinum toxin (BT) treatment. A retrospective analysis of anorectal physiological data collected for patients with resistant chronic anal fissures, referred to one consultant surgeon between 2007 and 2011, was undertaken. These were correlated with treatment plans and healing rates. Twenty-five patients with idiopathic chronic anal fissures underwent anorectal physiology studies and were subsequently treated with BT injection. Eleven had a characteristic high-frequency low-amplitude 'saw tooth' waveform or anal sphincter fibrillation (ASF) and higher anal sphincter pressures. Nine (82%) of these patients had resolution of their anal fissure symptoms following treatment with BT. Of 14 patients with no evidence of ASF and a greater range of anal sphincter pressures, only one (7%) had resolution following BT. ASF appears to be an anorectal physiological criterion that helps predict response of anal fissures to BT injection. This could help streamline fissure management. © 2013 The Authors.

Stapled haemorrhoidopexy is less painful than Milligan-Morgan haemorrhoidectomy, allowing an earlier return to working activities, but its long-term efficacy is not fully established. This study reports the long-term follow-up of a randomized clinical trial comparing the two techniques in 100 patients affected by third- and fourth-degree haemorrhoids. All patients were contacted and invited to attend the clinic to assess long-term functional outcome. The degree of continence and satisfaction were assessed by questionnaire. Anal manometry and anoscopy were performed. Eighty patients were available after a median follow-up of 87 months. No statistically significant differences were found between the two groups in terms of incontinence, stenosis, pain, bleeding, residual skin tags or recurrent prolapse. A tendency towards a higher recurrence rate was reported in patients with fourth-degree haemorrhoids, irrespective of the technique used. No significant changes in anal manometric values were found after surgery in either group. Both techniques are effective in the long term. Copyright (c) 2007 British Journal of Surgery Society Ltd.

The purpose of this study was to comprehensively evaluate the short-term outcomes after percutaneous embolization of the superior rectal artery (SRA) with metallic coils and particles for the management of hemorrhoids. Forty patients (15 men, 25 women) with a mean age of 35±5 years (SD) (range: 25-65 years) were prospectively enrolled. All patients had symptomatic hemorrhoids. The distribution of internal hemorrhoids was as follows: grade I (n=6, 16%); grade II (n=28, 69%) and grade III (n=6; 15%). All patients had percutaneous embolization of the SRA with metallic coils and synthetic polyvinyl alcohol particles. Follow-up evaluation included clinical examination, rectoscopy, histopathological analysis of rectal mucosa, duplex Doppler blood flow quantification, electromyography, sphincterometry of the anal sphincter and analysis of patient satisfaction. No immediate complications were observed and no patients had anal pain syndrome after embolization. Hemorrhoids showed a 43% size reduction after embolization (P<0.05). Taking into account the symptom resolutions such as irritation, discomfort, bloody discharge and pain, satisfaction was observed in 5/6 (83%) patients with grade III hemorrhoids and 32/34 patients (94%) with grades I-II hemorrhoids. One month after embolization, anal sphincter contractility normalized and no changes in anal electromyography were observed. Blood flow in the hemorrhoidal plexus dropped from 109±1.2ml/min/100g (SD) before treatment to 60.2±4.4ml/min/100g (SD) (P<0.05) the day after embolization and remained unchanged one month after embolization. Our study demonstrates that embolization of SRA with particle and coils does not lead to ischemia in patients with symptomatic hemorrhoids. Short-term results with regard to symptom management for hemorrhoidal disease are very encouraging and should stimulate further prospective and multicenter studies.

Enterobius vermicularis (pinworm) infestation in a child presenting with symptoms of acute appendicitis: a wriggly tale!

2017-10-06

Acute appendicitis is the most common surgical emergency worldwide. However, it can still present a challenging diagnosis especially in the young, elderly and those individuals of reproductive age, thus encompassing a wide spectrum of varied clinical presentations. Parasitic infections of the appendix are a rare cause of acute appendicitis. However, they must be considered in children presenting with abdominal pain. We report a case of Enterobius vermicularis infestation mimicking the features of acute appendicitis in a 10-year-old girl. This case is a cautionary reminder of the importance of considering E. vermicularis infestation in children presenting with abdominal pain, but who do not have a significantly raised white cell count or high Alvarado scores. A history of anal pruritus is the most characteristic symptom, but the parasites can cause severe abdominal pain mimicking appendicitis. Prompt recognition and a high clinical index of suspicion are required to prevent an unnecessary appendicectomy. Caution is advised when performing a laparoscopic appendectomy, as in our case, to prevent contamination of the peritoneum. This infestation is easily treatable with mebendazole. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

The Human Papillomavirus Vaccine: Current Perspective and Future Role in Prevention and Treatment of Anal Intraepithelial Neoplasia and Anal Cancer

Mehta, Mudresh R.; Lewis, James S.; Lockhart, A. Craig

2016-01-01

The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are rising in the U.S. and globally. Five-year survival rates with current modalities of treatment for anal cancer are generally favorable for localized and regional disease. For metastatic disease, the relative survival rate is poor. Major contributing factors for the increase in anal cancer incidence include increasing receptive anal intercourse (hetero- and homosexual), increasing HPV infections, and longer life expectancy of treated people who are seropositive for human immunodeficiency virus. Because treatment outcomes with systemic therapy in patients with advanced disease are so poor, prevention may be the best approach for reducing disease burden. The association of a major causative agent with anal cancer provides an excellent opportunity for prevention and treatment. The advent of the HPV vaccine for anal cancer prevention and treatment is a significant milestone and has the potential to greatly impact these cancers. The data regarding potential use of the HPV vaccine in anal cancer prevention and treatment are reviewed. Implications for Practice: The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are on the rise in the U.S. and globally. Based on recent studies, the HPV vaccine is approved for prevention of the infection and development of HPV-related anal cancer. In addition, several small studies have shown that the vaccine may be useful as adjuvant therapy for anal cancer. There is a need for public health strategies aimed at education of both patients and practitioners to improve the use of the vaccine for prevention of HPV-related anal cancer. The development of a therapeutic vaccine is a work in progress. PMID:26961923

[Surgical treatment of anal fistula].

Zeng, Xiandong; Zhang, Yong

2014-12-01

Anal fistula is a common disease. It is also quite difficult to be solved without recurrence or damage to the anal sphincter. Several techniques have been described for the management of anal fistula, but there is no final conclusion of their application in the treatment. This article summarizes the history of anal fistula management, the current techniques available, and describes new technologies. Internet online searches were performed from the CNKI and Wanfang databases to identify articles about anal fistula management including seton, fistulotomy, fistulectomy, LIFT operation, biomaterial treatment and new technology application. Every fistula surgery technique has its own place, so it is reasonable to give comprehensive individualized treatment to different patients, which may lead to reduced recurrence and avoidance of damage to the anal sphincter. New technologies provide promising alternatives to traditional methods of management. Surgeons still need to focus on the invention and improvement of the minimally invasive techniques. Besides, a new therapeutic idea is worth to explore that the focus of surgical treatment should be transferred to prevention of the formation of anal fistula after perianal abscess.

To compare the short- and long-term perineal consequences (at 6 months postpartum) and short-term neonatal consequences of instrumental rotation (IR) to those induced by assisted delivery (AD) in the occiput posterior (OP) position, in case of manual rotation failure. A prospective observational cohort study; tertiary referral hospital including all women presenting with persistent OP position who delivered vaginally after manual rotation failure with attempted IR or AD in OP position from September 2015 to October 2016. Maternal and neonatal outcomes of all attempted IR deliveries were compared with OP operative vaginal deliveries. Main outcomes measured were pelvic floor function at 6 months postpartum including Wexner score for anal incontinence and ICIQ-FLUTS for urinary symptoms. Perineal morbidity comprised severe perineal tears, corresponding to third and fourth degree lacerations. Fetal morbidity parameters comprised low neonatal Apgar scores, acidaemia, major and minor fetal injuries and neonatal intensive care unit admissions. Among 5265 women, 495 presented with persistent OP positions (9.4%) and 111 delivered after manual rotation failure followed by AD delivery: 58 in the IR group and 53 in the AD in OP group. The incidence of anal sphincter injuries was significantly reduced after IR attempt (1.7% vs. 24.5%; p < 0.001) without increasing neonatal morbidity. At 6 months postpartum, AD in OP position was associated with higher rate of anal incontinence (30% vs. 5.5%, p = 0.001) and with more urinary symptoms, dyspareunia and perineal pain. OP operative deliveries are associated with significant perineal morbidity and pelvic floor dysfunction at 6 months postpartum.

The aim of the present study was to describe the prevalence of anal sphincter tears (AST) in relation to obstetric management and technique during vacuum extraction deliveries (VE) (re: indications, the station of the fetal head at application of the cup, number of tractions, the length for the extraction, cup detachments, pain relief, episiotomy, fetal presentation, and experience of the operator) as well as maternal and infant anthropometrics. Descriptive study. Data on six hundred vacuum extraction deliveries were consecutively collected from six different delivery units in Sweden. Each unit contributed with data on 100 deliveries. The final study population included 596 women who delivered by vacuum extraction. There was no correlation between the management of the vacuum extraction and risk for anal sphincter tear. Women from Africa had nearly a fourfold risk for anal sphincter tear during vacuum-assisted delivery compared with Swedish-born women (OR 3.82 CI 1.47-9.89). Compared with infants with birth weight less than 4000 g, birth weight above 4000 g was associated with increased risk of AST (OR 1.87 CI 1.06-3.28). In this study, the obstetric management in VE-assisted deliveries did not impact the risk of AST. Copyright © 2015 Elsevier B.V. All rights reserved.

Trends in obstetric anal sphincter injuries over 10 years.

PubMed

Tyagi, V; Perera, M; Guerrero, K

2013-11-01

Obstetric anal sphincter injuries (OASIS) is a known complication of vaginal delivery and has significant public health issues, as it can cause both short- and long-term morbidity in women. The most commonly reported complications include different grades of faecal/flatus incontinence, pain and sexual dysfunction. In our study, we found a rising trend in OASIS rates in vaginal deliveries, with the rising rate of forceps and the falling rate of SVD, which is at least partly due to increased awareness and training in OASIS. However, there is an actual increase in the number of such tears at vaginal deliveries. Midwifery and obstetric practices have certainly changed over the last decade and we discuss the possible factors, which might be contributing to such a rise.

Anorectal melanoma is an uncommon and aggressive mucosal melanocytic malignancy. Due to its rarity, the pre-operative diagnosis remains difficult. The first symptoms are non-specific such as anal bleeding, anal mass or pain. Although anorectal melanoma carries a poor prognosis; optimal therapeutics strategies are unclear. Surgical resection remains the mainstay of treatment. The optimal surgical procedure for primary tumours is controversial and can vary from wide local excision or endoscopic mucosal resection (EMR) to an abdomino-perineal resection. A high degree of uncertainly exists regarding the benefit of radiation therapy or chemotherapy. The treatment of advanced melanoma is evolving rapidly with better understanding of the disease biology and immunology. Considerable effort has been devoted to the identification of molecular determinants of response to target therapies and immunotherapy. PMID:29492238

We report two cases of acute proctocolitis caused by rectal application of caustic products of domestic use. One 61-yr-old woman applied an ammonia solution enema; the other patient, a 63-yr-old woman, accidentally applied an enema containing lye. Both patients presented with intense anal pain, but the first patient also had abdominal pain with guarding, hematochezia, and leucocytosis. An acute proctocolitis was found at sigmoidoscopy in both patients. Only conservative and symptomatic measures were prescribed in both cases, and a clinical and endoscopic recovery was seen. In spite of persistent fibrosis in the lamina propria, no signs of stenosis were found.

The effect of cassia fistula emulsion on pediatric functional constipation in comparison with mineral oil: a randomized, clinical trial

PubMed Central

2012-01-01

Background The prevalence of Pediatric Functional Constipation (FC) has been reported between 0.7% to 29.6%. This study was conducted to compare the laxative effect of cassia fistula emulsion (CFE) with mineral oil (MO) on FC. Cassia fistula is named in Traditional Iranian Medicine (TIM) as “Folus”. Materials and methods A randomized clinical trial was carried on 81 children (age range: 4–13 years) with FC, according to Rome III criteria in Amirkola Children’s Hospital, Babol, Iran. They received CFE or MO randomly for three weeks. CFE was produced according to the order of TIM references. Children were counted as improved when they exited from Rome III criteria of FC. Frequency of defecation, fecal incontinence, retentive posturing, severity of pain, consistency of stool and anal leakage of oily material were compared between the two groups and with baselines. An intent-to-treat analysis was used. Safety of drugs was assessed with the evaluation of clinical adverse effects. Results 41 children were assigned randomly to receive CFE and 40 children received MO. After three weeks of medication, 84% of children in CFE group and 50% in MO group (p = 0.002) exited from the criteria of FC, so called improved. All measurable criteria improved in both groups. The frequency of defecation in CFE group improved from 1.7 per week (before the study) to 10.6 per week (at the third week) while this parameter differed in MO group from 2 to 6.1 (p < 0.001). The severity of pain during defecation and consistency of stool improved significantly better in CFE group than MO group (p < 0.05), but there were not any significant differences between the two groups in fecal incontinence and retentive posturing. Anal leakage of oily material occurred as an important complication in MO group while the children in CFE group did not complaint it. Drug’s compliances were not significantly different in the two groups. CFE and MO did not cause clinically significant side effects. Conclusions CFE was most effective than MO in the 3-week treatment of children with FC. PMID:23351337

The incidence of anal cancer is increasing especially among HIV-infected persons in the HAART era. Treatment of this cancer is based upon traditional chemoradiotherapeutic approaches, which are associated with high morbidity and of limited effectiveness for patients with high-grade disease. The mammalian target of rapamycin (mTOR) pathway has been implicated in several human cancers, and is being investigated as a potential therapeutic target. In archival human anal cancers, we observed mTOR pathway activation. To assess response of anal cancer to mTOR inhibition, we utilized two newly developed mouse models, one in which anal cancers are induced to arise in HPV16 transgenic mice and the second a human anal cancer xenograft model. Using the transgenic mouse model, we assessed the preventative effect of rapamycin on neoplastic disease. We saw significant changes in the overall incidence of tumors, and tumor growth rate was also reduced. Using both the transgenic mouse and human anal xenograft mouse models, we studied the therapeutic effect of rapamycin on preexisting anal cancer. Rapamycin was found to significantly slow, if not stop, the growth of both mouse and human anal cancers. As has been seen in other cancers, rapamycin treatment led to an activation of the MAPK pathway. These results provide us cause to pursue further the evaluation of rapamycin as a therapeutic agent in the control of anal cancer. ©2010 AACR.

Anal intraepithelial neoplasia: A review of diagnosis and management

PubMed Central

Roberts, Joseph R; Siekas, Lacey L; Kaz, Andrew M

2017-01-01

Anal intraepithelial neoplasia (AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus (HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior. A history of HPV-mediated genital cancer, which suggests infection with an oncogenic HPV strain, is another risk factor for AIN/anal cancer. Because progression of AIN to anal cancer is known to occur in some individuals over several years, screening for AIN and early anal cancer, as well as treatment of advanced AIN lesions, is reasonable in certain high-risk populations. Although randomized controlled trials evaluating screening and treatment outcomes are lacking, experts support routine screening for AIN in high risk populations. Screening is performed using anal cytological exams, similar to those performed in cervical cancer screening programs, along with direct tissue evaluation and biopsy via high resolution anoscopy. AIN can be treated using topical therapies such as imiquimod, 5-flurouracil, and trichloroacetic acid, as well as ablative therapies such as electrocautery and laser therapy. Reductions in AIN and anal cancer rates have been shown in studies where high-risk populations were vaccinated against the oncogenic strains of HPV. Currently, the CDC recommends both high-risk and average-risk populations be vaccinated against HPV infection using the quadrivalent or nonavalent vaccines. It is important for clinicians to be familiar with AIN and the role of HPV vaccination, particularly in high risk populations. PMID:28255426

2012-07-01

Enterobius vermicularis is one of the most common intestinal nematode worldwide. Enterobius rarely causes a symptomatic disease. We report here an unusual case of a 60-year old man who came with a polypoidal growth in the anal canal increasing in size for past 20 years. He had pain and intense itching over the mass. The differential diagnosis of squamous papilloma, fibroma and foreign body granuloma were considered. The mass lesion was excised surgically and sent to the pathology laboratory. The mass turned out to be an "E. vermicularis worm granuloma" by histopathologic examination. Thus, timely reporting and surgical resection of such lesion is necessary to prevent further complications. This case is reported here for the unusual presentation of pinworm as a pseudoneoplasm in the anal canal. Incidence of these cases reflected the poor personal hygiene and improper disposal of human excreta in the rural areas. We insist that health education is the only way to control the spread of helminthic infections that causes a heavy disease burden to our country.

85 patients at age of 27-68 years (44.78+/-9.02) with stage III-IV hemorrhoids were treated. Trans-anal disarterization of internal hemorrhoids under Doppler control with mucopexy and lifting was carried out using modified Moricorn proctoscope. Operation duration amounted 24-45 minutes (32+/-5.21). Postoperative pain syndrome amounted on average 33.2+/-0.52 mm (range 20-50 mm) on the first day and 16.5+/-0.10 (0-40 mm) during 5 days which didn't require usage of narcotic analgesics. Patients returned to labor activity after 2-4 days (2.79+/-0.81). They were investigated after 6 months after operation. Bleeding stopped in 96.5% of patients, prolapsed piles were not observed in 91.8% of patients. Repeated bleedings were not registered. Complications (perianal hematoma-like external node thrombosis) were revealed in 7 (8.2%) patients. Trans-anal disarterization of internal hemorrhoids under Doppler control with mucopexy and lifting is a safe and effective alternative to hemorrhoidectomy. This method is ideal for "one-day" hospital.

Pharmacological Sphincterotomy for Chronic Anal Fissures by Botulinum Toxin A

PubMed Central

Wollina, Uwe

2008-01-01

Chronic anal fissure is a common proctologic disease. Botulinum toxin (BTX) can be used for temporary chemical denervation to treat this painful disorder. Its application is by intramuscular injections into either the external or internal anal sphincter muscle. The mode of action, application techniques, and possible complications or adverse effects of BTX therapy are discussed in this report. The healing rate is dependent on the BTX dosage. The short-term healing rate (≤ 6 months) is 60–90%, whereas about 50% of the patients show a complete response in long-term follow-up studies (> 1 year). Adverse effects are generally mild, but relapses occur more often than with surgery. Conservative therapy is currently considered as a first-line treatment. With increasing evidence for its efficacy, BTX can now be considered among the first-line nonsurgical treatements. Although, surgical management by lateral sphincterotomy is the most effective treatment, it shows a higher incidence of incontinence and greater general morbidity rate than BTX. BTX is a useful alternative to surgery and in many cases, surgery can be avoided with the use of BTX. PMID:20300345

Rates of anal squamous cell carcinoma have increased over recent decades. The aim of this study was to describe characteristics of widely viewed YouTube videos about anal cancer. A total of 57 videos were identified and reviewed. Videos were assessed and coded with respect to date uploaded, upload source, gender of presenter, number of views, length in minutes, number of likes and dislikes, and selected aspects of content. Each video was assessed to determine if the sole purpose of the video was to provide information regarding anal cancer or existed to serve another purpose. Content related to anal cancer was categorized. The mean number of views was 23,548 (range 1014-440,078), and the average length of videos was 8:14 min. The upload source of 57 videos was 19 (33.3%) by consumers, 12 (21.1%) by professional, and 26 (45.6%) by news-based sources. More than half ( n = 30; 52.6%) had the sole purpose of providing information. The most frequently mentioned topics were treatment ( n = 25, 43.9%), symptoms ( n = 15, 26.3%), encouraging screening, human papillomavirus, and pain, respectively ( n = 14, 26.4% for each); only 6 of the 57 videos (10.5%) specifically mentioned prevention. None of 57 most widely viewed videos were uploaded by any agency of the U.S. Public Health Service or by any other U.S. governmental agency. It is important for health practitioners to be aware of the type of information available for their patients on the YouTube platform.

We report a case of chronic arthritis of the right hip joint in an otherwise healthy young male athlete as a complication of inadequately treated anal fistula. A young male athlete presented with symptoms of right hip pain and difficulty in walking and intermittent fever for 2 months. He had a history of perianal abscess drainage. On examination he was found to have a tender right hip joint with severe restriction of movements. He was also found to have a partially drained right ischiorectal abscess. X-ray and MRI of the hip joint revealed chronic arthritis of the right hip joint, which was communicating with a complex fistula-in-ano. He underwent a diversion sigmoid colostomy and right ischiorectal abscess drainage along with appropriate antibiotics with a plan for definitive hip joint procedure later. He was lost to follow-up and succumbed to severe perianal sepsis within a few months. PMID:25414226

To demonstrate the effectiveness of the treatment of internal hemorrhoids with rubber band ligation (RBL) and infrared photocoagulation (IRC). From march 1996 to december 1999, we prospectively studied 358 patients with a total of 817 hemorrhoid groups and a follow-up period of 36 months. Distribution according to gender and age was: 210 men with a mean age of 46 years and 148 women with a mean age 45.8 years. The mean number of hemorrhoids treated per patients was 2.3. All of them had complete a follow-up protocol at 15, 30, 60 and 180 days and at 12, 24 and 36 months. Rubber band ligation was performed with McGown ligator and suction pump, placing the band at the base of the hemorrhoid. For the infrared coagulation we used a Lumatec coagulation system, applying at least four shoots around each hemorrhoid, with an exposition time ranging between 1 and 1.5 seconds. Treatment was considered effective when patients became asymptomatic (relief of pain, bleeding or anal itching) and the obliteration of hemorrhoids after the treatment was confirmed by anal inspection and anoscopy. Two hundred ninety five of 358 patients were treated with RBL (82.4%), this treatment being effective in 98% of the patients after 180 days and very good after 36 months. There were 6/295 relapses at 36 months (2%). All minor and major complications were observed within the first 15 days of treatment: rectal tenesmus in 96/295 patients (32.5%), mild anal pain in 115/295 (38.9%), self-limited and mild bleeding after the detachment of the bands in 30/295 (10%), and febricula in one patient. Sixty three of 358 patients were treated with IRC (17.6%). In this group, relapses were observed in 6/63 patients (9.5%) at 36 months, all of them with grade III hemorrhoids that required additional treatment with RBL. All the complications (inherent to the technique) were observed within the first days: mild anal pain in 40/63 patients (63.4%) and mild bleeding in 1/63 (1.6%). The treatment with RBL or IRC depended on the number of hemorrhoids and the hemorrhoidal grade. No significant differences were found regarding the effectiveness between RBL and IRC for the treatment of grade I-II hemorrhoids, while RBL was more effective for grade III and IV hemorrhoids (p < 0.05). RBL and IRC should be considered as a good treatment for all grades of hemorrhoids, due to its effectiveness, its cost-benefit and its small short and long-term morbidity.

To investigate the structural and functional changes of internal anal sphincter (IAS) in children with functional constipation (FC), and to evaluate the association between the thickness of IAS and the severity of clinical symptoms. A total of 35 children with FC(constipation group,17 with incontinence) between June 2008 and December 2008 at the Shengjing Hospital of China Medical University were evaluated using anal manometry and endosonography. These patients were compared to 23 hospitalized children who were excluded for digestive and endocrinal diseases(control group). A validated symptom score(SS) was used to assess the severity of symptoms. The sum of SS ranged between 0 and 65. Anorectal manometry showed reflex relaxation of IAS in response to distension of rectal balloon in all patients. Rectal perceptional threshold in FC group was significantly higher than that in the controls[(42.4 ± 19.5) ml vs.(29.1 ± 15.6) ml, P<0.05]. The lowest volume for inducing reflex relaxation of IAS was significantly higher than that in the controls [(55.6 ± 31.6) ml vs.(30.5 ±13.8) ml, P<0.05]. The thickening of IAS was noted in all the patients[(3.8 ± 1.7) mm vs.(2.5 ± 1.0) mm, P<0.05]. However, there was no significant difference between FC and control in median resting anal sphincter pressure[(170.8 ± 62.3) mm Hg vs. (161.3 ± 51.1) mm Hg, P>0.05]. The median symptom score was 9.3 ± 4.3 in the FC group. The thickness of IAS correlated significantly with total symptom severity score(r=0.407, P<0.05). There was no correlation between thickness of IAS and age, sex, or duration of disease(P>0.05). Structural and functional changes of internal anal sphincter exist in children with functional constipation. The thickness of internal anal sphincter correlates significantly with symptom severity.

High resolution anorectal manometry has been developed over the past years, as well as 3D high definition manometry (HDARM). However, the clinical impact of the results obtained with these new technologies remains to be determined. We thus analyzed various HDARM parameters of anal sphincter function and tested their capacity to discriminate between patients with constipation and those with fecal incontinence. One hundred and fourteen consecutive patients underwent the same HDARM protocol (Medtronic), including 2 short duration voluntary anal contractions (5seconds) and 1 sustained (as long as possible) contraction. Various parameters evaluating the anal sphincter function were measured, based on automatic software analysis and Smartmouse™ item of the software; resting anal pressures, anal pressures and incremental pressures during voluntary squeeze and cough anal reflex. The ability of these parameters to discriminate between patients with fecal incontinence and chronic constipation was assessed using areas under the curves of ROC curves. All parameters were highly correlated. The most discriminant variable was found to be the mean anal pressure during sustained squeeze. The 3D lambda aspect of the anal sphincter during voluntary contraction was as frequently absent in both groups of patients (13% in patients with chronic constipation, versus 23% in those with fecal incontinence, P=0.18). There was a significant correlation between the fecal incontinence Wexner score and the voluntary anal contraction variables. Several parameters to assess the quality of voluntary anal contraction have been proposed. We observed with HDARM that the most discriminant parameter was the mean anal pressure during sustained squeeze. This may help to standardize and simplify HDARM protocols.

Bleeding per rectum is an uncommon presentation in pediatric patients. Heterotopic gastric mucosa in the rectum is a rare cause of rectal bleeding. Here, we report a 3-year-old child with a bleeding rectal ulcer that was initially diagnosed and managed as a solitary rectal ulcer syndrome. After 1 month, the patient persisted to have intermittent rectal bleed and severe anal pain. Repeat colonoscopy showed the worsening of the rectal ulcer in size. Pediatric surgeon excised the ulcer, and histopathological examination revealed a gastric fundic-type mucosa consistent with the diagnosis of gastric heterotopia of the rectum. Over the following 18 months, our patient had experienced no rectal bleeding and remained entirely asymptomatic. In conclusion, heterotopic gastric mucosa of the rectum should be considered in the differential diagnosis of a bleeding rectal ulcer.

To report the signalment, clinical presentation, treatments pursued and outcomes of dogs with malignant anal sac melanoma. Medical records from five institutions from January 2000 through December 2015 were reviewed and dogs with cytologically- or histologically-confirmed malignant anal sac melanoma were identified. Signalment, clinical signs, staging, cytology, histopathologic analysis, surgical and non-surgical treatments were extracted from the medical records. The referring veterinarians and owners were contacted for follow-up data. Eleven dogs were included and survival data was available for all. The most common clinical signs were bloody anal sac discharge and perianal licking. Initial treatments pursued included surgery (n=8), chemotherapy (n=1), and palliative treatment with pain medications and stool softeners (n=2). In an adjuvant setting, melanoma vaccine was pursued following surgery in three dogs and chemotherapy in one dog. Regardless of treatment, progression-free survival (mean 92 · 5 days) and overall survival times (median 107 days) were short. Dogs in this case series had a guarded to poor prognosis regardless of treatment. Ten of 11 dogs were euthanased due to local or distant disease progression. Only 1 of 11 dogs was alive one year after diagnosis. An understanding of tumour behaviour in this location could lead to improved survival times with earlier diagnosis and treatment. © 2017 British Small Animal Veterinary Association.

Pharmacological treatment of hemorrhoids: a narrative review.

Altomare, Donato F; Giannini, Ivana

2013-12-01

Hemorrhoid disease is the cause of most proctologic complaints and hundreds of medical and surgical therapies have been proposed to relieve symptoms. However, the role and the correct indication of medical treatments are still controversial. Further, the utility of conservative measures are rarely scientifically supported by adequate trials. This narrative review is based on the search and analysis of full papers in English language selected from PubMed in the past 30 years using the following MeSH Editing: hemorrhoids, conservative treatment, medical treatment and hemorrhoids, pregnancy and hemorrhoids, thrombosed hemorrhoids, randomized trials and hemorrhoids, postoperative pain and hemorrhoids. Early stages (I/II degrees) of this disease could be effectively managed conservatively with several approaches as lifestyle changes, fiber supplement, topical ointments and phlebotonic drugs. The more advanced hemorrhoid stages (III/IV degrees) need some type of surgery, but medical therapy is still useful to minimize anal symptoms as a bridge-to-surgery treatment. Further, post-hemorrhoidectomy pain, hemorrhoidal crisis even in pregnancy could benefit from the adjunct of local and systemic medical treatment. This expert opinion, based also on long-lasting clinical practice, also supports the use of medical treatment in symptoms relief in patients with hemorrhoid disease.

Maternal body mass index and risk of obstetric anal sphincter injury.

To estimate the association between maternal obesity and risk of three different degrees of severity of obstetric anal sphincter injury. The study population consisted of 436,482 primiparous women with singleton term vaginal cephalic births between 1998 and 2011 identified in the Swedish Medical Birth Registry. Women were grouped into six categories of BMI. BMI 18.5-24.9 was set as reference. Primary outcome was third-degree perineal laceration, partial or total, and fourth-degree perineal laceration. Adjustments were made for year of delivery, maternal age, fetal head position at delivery, infant birth weight and instrumental delivery. The overall prevalence of third- or four-degree anal sphincter injury was 6.6% (partial anal sphincter injury 4.6%, total anal sphincter injury 1.2%, unclassified as either partial and total 0.2%, or fourth degree lacerations 0.6%). The risk for a partial, total, or a fourth-degree anal sphincter injury decreased with increasing maternal BMI most pronounced for total anal sphincter injury where the risk among morbidly obese women was half that of normal weight women, OR 0.47 95% CI 0.28-0.78. Obese women had a favourable outcome compared to normal weight women concerning serious pelvic floor damages at birth.

Interest about hemorrhoids is related to its high incidence and elevated social costs that derive from its treatment. Several comparative studies are reported in Literature to define a standard for ideal treatment of hemorrhoidal disease. Radical surgery is the only therapeutic option in case of III and IV stage haemorrhoids. Hemorrhoids surgical techniques are classified as Open, Closed and Stapled ones. We report our decennial experience on surgical treatment focusing on early, middle and late complications, indications and contraindications, satisfaction level of each surgical procedure for hemorrhoids. Four hundred forty-eight patients have been hospitalized in our department fom 1st January to 31st December 2008. Of these 241 underwent surgery with traditional open or closed technique and 207 with the SH technique according to Longo. This retrospective study includes only patients with symptomatic hemorrhoids at III or IV stage. There were no differences between CH and SH about both pre and post surgery hospitalization and intraoperative length. Pain is the most frequently observed early complication with a statistically significant difference in favour of SH. We obtain good results in CH group using anoderma sparing and perianal anaesthetic infiltration at the end of the surgery. In all cases, pain relief was obtained only with standard analgesic drugs (NSAIDs). We also observed that pain level influences the outcome after surgical treatment. No chronic pain cases were observed in both groups. Bleeding is another relevant early complication in particular after SH: we reported 2 cases of immediate surgical reintenvention and 2 cases treated with blood transfusion. Only in SH group we report also 5 cases of thrombosis of external haemorrhoids and 7 perianal hematoma both solved with medical therapy There were no statistical significant differences between two groups about fever, incontinence to flatus, urinary retention, fecal incontinence, substenosis and anal burning. No cases of anal stenosis were observed. About late complications, most frequently observed were rectal prolapse and hemorrhoidal recurrence, especially after SH. Our experience confirms the validity of both CH and SH. Failure may be related to wrong surgical indication or technical execution. Certainly CH procedure is more invasive and slightly more painfull in immediate postoperative period than SH surgery, which is slightly more expensive and has more complications. In our opinion the high risk of possible early and immediate complications after surgery requires at least a 24 hours hospitalization length. SH is the gold standard for III grade haemorrhoids with mucous prolapse while CH is suggested in IV grade cases. Hemorrhoidal arterial ligation operation (HALO) technique in III and IV degree needs further validations.

Is anal sex a marker for sexual risk-taking? Results from a population-based study of young Croatian adults.

PubMed

2011-09-01

There is evidence that anal sex is becoming increasingly popular among heterosexual women and men. Several studies carried out in especially vulnerable populations (e.g. sex workers and low-income youth) suggested that anal sex may indicate a more general propensity to sexual risk-taking. To assess whether this epidemiologically important finding holds in the case of young adults from the general population, we analysed data from a cross-sectional probability survey carried out in 2010 on 1005 Croatian women and men aged 18-25. Anal intercourse was reported by 36.5% of 861 sexually experienced participants (42.7% of men and 29.8% of women). About one-third of them (34%) used a condom at most recent anal intercourse. The experience of anal sex was significantly associated (P<0.001) with all four indicators of sexual risk-taking (condom use at most recent vaginal intercourse, number of sexual partners in the past year, concurrent sexual relationships and anonymous sex in the past year), as well as with negative attitudes and beliefs about condom use (P<0.01). Sexual sensation-seeking mediated the relationship between anal sex and some of the sexual risk-taking behaviours. According to the findings, heterosexual anal sex is directly and indirectly associated with increased behavioural risks of acquiring HIV and other sexually transmissible infections (STI). Sex education and STI prevention programs should focus on the importance of using protection when practicing anal sex.

The study aimed to verify the role of parity, age and bowel function in the pathogenesis of anorectocele. A cross-sectional study was conducted regarding age, obstetrical history, Cleveland Clinic Constipation Score (CCCS), cinedefecography and anal manometry findings. Forty-five adult women complaining of obstructed defecation were evaluated; the median age was 46 years and median CCCS, 13. Fifteen patients were nulliparous and 23 multiparous (median parity 2). Eighteen had a history of episiotomy, fourteen delivered large babies and two had forceps-assisted delivery. Statistical analysis was performed using Spearman's correlation test and Fisher's exact test. Anal hypertonia was found in 14 (31.1%) patients, anal hypotonia in eight (17.8%), anismus in 13 (28.9%) and anorectoceles in 34 (75.6%) [median size 2.8 cm (0-6.4)]. There were no correlations between anorectocele and anal hypertonia (P = 0.7171), anismus (P = 0.4666), parity comparing nulliparous and multiparous patients (P = 1.000), episiotomy (P = 1.0000), forceps assistance (P = 1.0000), delivery of a large baby (P = 1.0000) anal resting pressure (P = 0.0883), anal voluntary pressure (P = 0.7327), parity (P = 0.4987) and age (P = 0.8603). There were correlations between anorectocele and the CCCS (P = 0.0082) and anal hypotonia (P = 0.0141). Anorectocele is not correlated with parity, age, episiotomy, delivery of a large baby and anismus. It was more frequent in patients with severe constipation and less common in patients with anal hypotonia.

The incidence of intraepithelial anal neoplasia is increasing in certain risk behaviour groups, and human papillomavirus (HPV) infection is involved in its pathogenesis. The systematic use of anal cytology, and more recently HPV detection by hybrid capture and genotyping, have been introduced into screening programs in recent decades. A retrospective cohort study was carried out on individuals with risk behaviours of developing intraepithelial anal neoplasia and who attended Sexually Transmitted Infections clinics in the Dermatology area of the Hospital Costa del Sol from January 2010 to December 2012. The intraepithelial anal neoplasia screening was performed using anal cytology and HPV genotyping. Half (50%) of the study population were HIV positive. A high frequency of anal dysplasia and presence of HPV in cytology (82.1%) and genotype (79%) was found. A statistically significant association (P<.005) was obtained between the presence of high-risk HPV genotypes and the presence of high-grade dysplasia in the second directed cytology. HPV genotyping enabled 17 cases (22%) of severe dysplasia to be identified that were under-diagnosed in the first cytology. Cases of high-grade dysplasia can be under-diagnosed by a first anal cytology. Detection of HPV can supplement this procedure, leading to the identification of those patients most at risk of developing high-grade anal dysplasia.

Approach to hemorrhoids.

PubMed

Lohsiriwat, Varut

2013-07-01

Hemorrhoids are a very common anorectal disorder defined as the symptomatic enlargement and abnormally downward displacement of anal cushions. The current pathophysiologies of hemorrhoids include the degenerative change of supportive tissue within the anal cushions, vascular hyperplasia, and hyperperfusion of hemorrhoidal plexus. Low-grade hemorrhoids are easily and effectively treated with dietary and lifestyle modification, medical intervention, and some office-based procedures. An operation is usually indicated in symptomatic high-grade and/or complicated hemorrhoids. Whilst hemorrhoidectomy has been the mainstay of surgical treatment, more recently other approaches have been employed including Ligasure hemorrhoidectomy, stapled hemorrhoidopexy, and doppler-guided hemorrhoidal artery ligation. Post-procedural pain and disease recurrence remain the most challenging problems in the treatment of hemorrhoids. This article deals with modern approaches to hemorrhoids based on the latest evidence and reviews of the literature. The management of hemorrhoids in complicated situations is also discussed.

Surgery for ulcerative colitis is a major and complex colorectal surgery. Laparoscopy benefits these patients with better outcomes in context of cosmesis, pain and early recovery, especially in young patients. For surgeons, it is a better tool for improving vision and magnification in deep cavities. This is not the simple extension of the laparoscopy training. Starting from preoperative preparation to post operative care there are wide variations as compared to open surgery. There are also many variations in steps of laparoscopic surgery. It involves left colon, right colon and rectal mobilisation, low division of rectum, pouch creation and anastomosis of pouch to rectum. Over many years after standardisation of this technique, it takes same operative time as open surgery at our centre. So we present our standardized technique of laparoscopic assisted restorative proctocolectomy and ileal pouch anal anastomosis (IPAA).

Antiretrovirals do not prevent anal intraepithelial neoplasia. However, the influence of antiretrovirals in the natural history of invasive anal cancer is less clear. The objective is to investigate the impact of antiretrovirals in the time to the development of anal cancer in HIV-positive MSM. A retrospective analysis of cases of anal cancer in a cohort of HIV-positive MSM receiving antiretrovirals between 1988 and 2008. Time from first CD4 cell count or HIV RNA viral load test to anal cancer diagnosis was analysed using Cox regression and Kaplan-Meier curves. Anal cancer cases treated in the era prior to HAART (<1996) were compared with those treated later (1996-2008). Anal cancer cases (n = 37) were compared with a cohort of 1654 HIV-positive MSM on antiretrovirals. Antiretrovirals were started in the pre-HAART era by 70% of cancer cases, and median CD4 cell count nadir was 70 cells/μl (10-130). Time to development of anal cancer was shorter for cases treated during the pre-HAART era [adjusted hazard ratio (AHR) 3.04, 95% confidence interval (95% CI) 1.48-6.24, P = 0.002], with a CD4 cell count nadir less than 100 cells/μl (AHR 2.21, 95% CI 1.06-4.62, P = 0.035) and longer duration of CD4 cell count less than 100 cells/μl (AHR 1.33, 95% CI 1.11-1.58, P = 0.002). Results show that severe immunosuppression and starting therapy pre-HAART are associated with an increased risk of anal cancer. HIV-positive MSM initiating antiretrovirals during the HAART era (1996-2008) had a longer time to the development of anal cancer than those treated pre-HAART. Our results suggest that early use of HAART may delay progression to anal cancer.

2015-06-01

In this study, we aimed to determine the prevalence of Enterobius vermicularis (E. vermicularis) using anal tape technique in four different primary schools in the town of Kayseri. For this purpose, cellophane-tape samples were collected from a total of 438 students. Of all the students, 229 (52.2%) are female and 209 (47.7%) are male. In this study, the relationship between E. vermicularis and the parameters such as school, gender, residential structure, bathroom, water source, parents' monthly income, the number of rooms and members in the house and some symptoms such as anal itching, nasal itching, allergies, irritability, headaches and dizziness, night fears, dental grinding at night, abdominal pain, diarrhea, loss of appetite and weight loss were investigated. E. vermicularis was determined in 44 of the 438 students (which is 10.4%). There were statistically significant relation between
E. vermicularis and parameters such as residential structure, the number of rooms in the house, dental grinding at night, abdominal pain, parents' level of education. There was also statistically significant relation between E. vermicularis and socio-echonomical situation of primary schools. We believe that carrying out periodic screening in schools in which especially low-income and parasite-infected children should be treated, informed about prevention and control methods.

Retention of urine and sacral paraesthesia in anogenital herpes simplex infection.

PubMed

Edis, R H

1981-01-01

Two definite and 2 probable cases of anogenital herpes simplex and sacral radiculitis are described. Symptoms were typical and consisted of paraesthesia and neuralgic pain in the perineum and legs, urinary retention and constipation occurring within several days to a week after an anogenital herpetic eruption. However, at presentation only 1 case had an obvious history of anogenital herpes simplex. Neurological signs were not striking and consisted of a reduced appreciation of light touch and pin prick over the sacral dermatomes and in 2 cases reduced anal sphincter tone. CSF examination in 3 patients showed a lymphocytosis. Bladder catheterisation was required for up to 2 weeks in 2 patients. The paraesthesia persisted for weeks to months. It should be more widely recognised that anogenital herpes simplex, with sacral radiculitis, is probably the commonest cause of acute retention of urine in young sexually active people.

Residual prolapsed piles is a problem after the stapled hemorrhoidopexy, especially in large third- or fourth-degree hemorrhoids. We have developed a method using additional traction sutures along with modified Longo's procedure to manage this problem. From January 2005 to October 2005, 30 consecutive patients with symptomatic third- or fourth-degree hemorrhoids who underwent the modified Longo's stapled hemorrhoidopexy with additional traction sutures in a single institution were collected. The demographics, postoperative pain score, surgical features, outcomes, and early and late complications were recorded. All patients were followed for a mean duration of 8.8 (range, 4-15) months. Thirty patients (17 males) with a mean age of 45 (range, 27-63) years were identified. The mean postoperative pain score on the morning of the first postoperative day was 2.8 (range, 1-4). The mean duration of operation was 30.7 (range, 25-37) min. The mean duration of hospital stay was 2 (range, 1-3) days. The mean days for patients to resume normal work was 6.7 (range, 4-9) days. No other procedure-related complications occurred in all patients. There was no early complication except for fecal urgency found in one patient during the first postoperative days. Regarding the late complications, no residual prolapsed piles, persistent anal pain, incontinence, anal stenosis, or recurrent symptoms were found. Our preliminary experiences indicated that this modified procedures truly contributed to reduce the residual internal hemorrhoids and maintained the benefits of stapled hemorrhoidopexy. Randomized trial and long-term follow-up warrant to determine possible surgical and functional outcome.

Maternal Body Mass Index and Risk of Obstetric Anal Sphincter Injury

PubMed Central

2014-01-01

Objective. To estimate the association between maternal obesity and risk of three different degrees of severity of obstetric anal sphincter injury. Methods. The study population consisted of 436,482 primiparous women with singleton term vaginal cephalic births between 1998 and 2011 identified in the Swedish Medical Birth Registry. Women were grouped into six categories of BMI. BMI 18.5–24.9 was set as reference. Primary outcome was third-degree perineal laceration, partial or total, and fourth-degree perineal laceration. Adjustments were made for year of delivery, maternal age, fetal head position at delivery, infant birth weight and instrumental delivery. Results. The overall prevalence of third- or four-degree anal sphincter injury was 6.6% (partial anal sphincter injury 4.6%, total anal sphincter injury 1.2%, unclassified as either partial and total 0.2%, or fourth degree lacerations 0.6%). The risk for a partial, total, or a fourth-degree anal sphincter injury decreased with increasing maternal BMI most pronounced for total anal sphincter injury where the risk among morbidly obese women was half that of normal weight women, OR 0.47 95% CI 0.28–0.78. Conclusion. Obese women had a favourable outcome compared to normal weight women concerning serious pelvic floor damages at birth. PMID:24839604

Proctalgia fugax is characterized by a sudden internal anal sphincter and anorectic ring attack of pain of a short duration. Description of the influence of intravenous lidocaine treatment for proctalgia fugax. A 28-year-old patient suffering of proctalgia fugax for 8 months. Conventional treatment efforts did not improve his condition. A single dose of an intravenous lidocaine infusion completely stopped his pain attacks. Based on the experience reported in this case and the potential benefit of this treatment for proctalgia fugax, controlled studies comparing intravenous lidocaine with placebo should be conducted to confirm the observation and to provide a more concrete basis for the use of intravenous lidocaine for this indication.

Regenerative medicine provides alternative strategies for the treatment of anal incontinence.

2017-03-01

Anal incontinence is a common disorder but current treatment modalities are not ideal and the development of new treatments is needed. The aim of this review was to identify the existing knowledge of regenerative medicine strategies in the form of cellular therapies or bioengineering as a treatment for anal incontinence caused by anal sphincter defects. PubMed was searched for preclinical and clinical studies in English published from January 2005 to January 2016. Animal studies have demonstrated that cellular therapy in the form of local injections of culture-expanded skeletal myogenic cells stimulates repair of both acute and 2 - 4-week-old anal sphincter injuries. The results from a small clinical trial with ten patients and a case report support the preclinical findings. Animal studies have also demonstrated that local injections of mesenchymal stem cells stimulate repair of sphincter injuries, and a complex bioengineering strategy for creation and implantation of an intrinsically innervated internal anal sphincter construct has been successfully developed in a series of animal studies. Cellular therapies with myogenic cells and mesenchymal stem cells and the use of bioengineering technology to create an anal sphincter are new potential strategies to treat anal incontinence caused by anal sphincter defects, but the clinical evidence is extremely limited. The use of culture-expanded autologous skeletal myogenic cells has been most intensively investigated and several clinical trials were ongoing at the time of this report. The cost-effectiveness of such a therapy is an issue and muscle fragmentation is suggested as a simple alternative.

Anal fistulas are a common manifestation of Crohn’s disease (CD). The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently employed. However, at the moment, none of these techniques appear superior to the others in terms of healing rate. Surgery is always indicated to treat symptomatic, simple, low intersphincteric fistulas refractory to medical therapy and those causing disabling symptoms. Utmost attention should be paid to correcting the balance between eradication of the fistula and the preservation of fecal continence. PMID:25309057

We studied DNA methylation patterns of human papillomavirus (HPV) and tumor suppressor gene EPB41L3 in 148 anal and perianal biopsies to determine whether high levels of methylation would be associated with anal intraepithelial neoplasia (AIN). The most prevalent HPV type was HPV16, detected in 54% of the 30 benign biopsies, 33% of the 43 low-grade AIN (lgAIN), 82% of the 59 high grade AIN (hgAIN) and 4 of the 5 anal cancers. A methylation score was developed (0.561*HPV16me+0.439*EPB41L3) which had increasing values with severity of disease: the mean was 8.1% in benign, 13.2% in lgAIN, 22.3% in hgAIN and 49.3% in cancers (p < 0.0001). The methylation score as a triage classifier at a cut-off of 8.8 gave a sensitivity of 90.6% (95% CI: 82.8, 96.9), specificity of 50.7% (95% CI: 39.7, 61.6) and area under the curve of 0.82 (95% CI: 0.75–0.89) for separating hgAIN and cancer from benign and lgAIN biopsies. We conclude that methylation of HPV16 and EPB41L3 show highly significant association with increasing severity of AIN and cancer and may be useful as biomarkers in anal disease. PMID:28881579

HIV diagnoses among men who have sex with men (MSM) have been increasing in several high-income countries. A better understanding of the sexual behavior trends among MSM can be useful for informing HIV prevention. We conducted a systematic review of studies that examined behavioral trends (1990-2013) in any condomless anal sex, condomless anal sex with an HIV-discordant partner, and number of partners. Studies included come from the United States, Europe, and Australia. We found increasing trends in condomless anal sex and condomless anal sex with an HIV-discordant partner, and a decreasing trend in number of partners. The increase in condomless anal sex may help to explain the increase in HIV infections. More explanatory research is needed to provide insight into factors that contribute to these behavior trends. Continuous monitoring of HIV, risk behaviors, and use of prevention and treatment is needed to evaluate prevention efforts and monitor HIV transmission risk.

Sphincter-sparing radiotherapy or chemoradiation are standard treatments for patients with anal cancer. The ultimate treatment goal is full recovery from anal cancer with preserved anorectal function. Unfortunately, long-term survivors often suffer from severe anorectal symptoms. The aim of the present study was to characterize changes in anorectal physiology after radiotherapy for anal cancer. We included 13 patients (10 women, age 63.4 ± 1.9) treated with radiotherapy or chemoradiation for anal cancer and 14 healthy volunteers (9 women, age 61.4 ± 1.5). Symptoms were assessed with scores for fecal incontinence and low anterior resection syndrome. Anorectal physiology was examined with anorectal manometry and the Functional Lumen Imaging Probe. Patients had a median Wexner fecal incontinence score of 5 (0-13) and a median LARS score of 29 (0-39). Compared to healthy volunteers, patients had lower mean (±SE) anal -resting (38 ± 5 vs. 71 ± 6, p < .001) and -squeeze pressures (76 ± 11 vs. 165 ± 15, p < .001). Patients also had lower anal yield pressure (15.5 ± 1.3 mmHg vs. 28.0 ± 2.0 mmHg, p < .001), higher distensibility, and lower resistance to flow (reduced resistance ratio of the anal canal during distension, q = 5.09, p < .001). No differences were found in median (range) rectal volumes at first sensation (70.5 (15-131) vs. 57 (18-132) ml, p > .4), urge (103 (54-176) vs. 90 (32-212), p > .6) or maximum tolerable volume (173 (86-413) vs. 119.5 (54-269) ml, p > .10). Patients treated with radiotherapy or chemoradiation for anal cancer have low anal resting and squeeze pressures as well as reduced resistance to distension and flow.

COX-2 expression in canine anal sac adenocarcinomas and in non-neoplastic canine anal sacs.

Anal sac adenocarcinoma (ASAC) is a clinically significant canine neoplasm characterized by early lymphatic invasion. Up-regulation of cyclooxygenase isoform 2 (COX-2) has been confirmed in several animal and human neoplastic tissues. The aim of the current study was primarily to evaluate COX-2 expression in canine ASAC and compare it to COX-2 expression in non-neoplastic canine anal sac tissue using immunohistochemistry with scoring for percentage positivity and intensity. Twenty-five ASAC samples and 22 normal anal sacs were available for evaluation. All canine ASAC samples and the normal anal sac tissues stained positively for COX-2. However, while normal anal sac tissue showed strong staining of the ductal epithelial cells, ASAC samples showed staining of the neoplastic glandular epithelial cells, with varying percentage positivity and intensity between ASAC samples. COX-2 immunoreactivity of ASAC samples was of low intensity in 52% and high in 12% of the cases; the remaining samples were of intermediate intensity. Seventy-six per cent of the ASAC had over 50% of the neoplastic glandular cells staining positive. These results confirm that COX-2 is expressed in the neoplastic glandular epithelial cells in canine ASAC and suggest a potential role for COX-2 inhibitors in the management of ASAC. Furthermore, the results indicate that COX-2 is expressed in ductal epithelial cells of the normal anal sac. Copyright © 2013 Elsevier Ltd. All rights reserved.

The effect of transanal haemorrhoidal dearterialization (THD) on continence and anorectal physiology has not yet been demonstrated. Twenty patients suffering from 3rd degree haemorrhoids were enrolled and underwent THD, including both dearterialization and mucopexy. Clinical assessment, anorectal manometry, rectal volumetry and endoanal ultrasound were performed preoperatively and at 6 months postoperatively. Postoperatively two and six patients had transient rectal pain and tenesmus, respectively. No patient reported faecal urgency or minor or major incontinence. All patients remained able to discriminate gas from faeces. No significant variation of the mean values of anal manometric and rectal volumetric parameters was recorded at 6 months of follow-up compared with preoperative values. At 6 months both internal and external sphincters were endosonographically intact. THD does not cause trauma to the anal canal and rectum. © 2011 The Authors.

We report the case of a 20-year-old man with a 2-month history of anal pain and bloody rectal discharge. He was referred to our clinic of gastroenterology for suspected inflammatory bowel disease (IBD). The colonoscopy showed mucosal nodularities on the rectum and an anal tag. Because the colonoscopic findings were not consistent with the typical manifestations of IBD, we took an additional sexual history and performed studies for infectious proctitis, including serologic tests for Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum. He had homosexual experience, and the serologic tests and PCR of a rectal swab were positive for C. trachomatis infection. Finally he was diagnosed as having chlamydial proctitis and was treated with intramuscular ceftriaxone 250 mg in a single dose and doxycycline 100 mg orally twice daily for 7 days. After 2 months, he had no lower abdominal symptoms and his endoscopic findings were improved.

The outcome of immediate repair of obstetric third-degree tears is poorly documented. Immediate repair may give better functional results than delayed repair because scarring is reduced. This aim of this prospective study was to examine the early outcome of immediate repair of third-degree tears. A total of 121 women who had immediate repair of obstetric third-degree tears underwent interview, anal ultrasonography and anorectal physiology. At review, 79 (65%) were completely asymptomatic (score = 0), 23 (19%), had minor flatus incontinence or mild urgency causing no compromise to their quality of life (score 1-4), and 19 (16%) had clinically embarrassing faecal incontinence (score 5-24). Thirty-nine (32%) had an intact internal anal sphincter (IAS) and external anal sphincter (EAS) (i.e. a successful repair), eight (7%) had a defect in the IAS alone but the EAS was intact (i.e. a successful repair but a residual IAS defect), 43 (35%) had a residual defect in the EAS alone (IAS intact) and 31 (26%) had a persistent defect in the IAS and EAS. Residual defects in either or both of the sphincters were associated with a significantly higher incidence of abnormal resting and squeeze anal pressures. Anal manometry had no correlation with symptoms. The highest proportion of severe incontinence was in those with an IAS defect alone (37%) and when there was a residual IAS and EAS defect (24%). Only 2 of 39 (5%) with an intact IAS and EAS had severe incontinence and only 8 of 43 (18%) with a residual EAS defect alone had severe faecal incontinence. These results indicate a good outcome following immediate repair of third-degree obstetric tears and emphasize the role of the IAS in providing continence.

This training activity aimed at increasing the knowledge of anal cancer screening, diagnostic and treatment options in medical students and physicians, to determine the interest of these individuals in receiving training in the diagnosis and treatment of anal cancer, and to explore any previous training and/or experience with both anal cancer and clinical trials that these individuals might have. An educational activity (1.5 contact hours) was attended by a group of medical students, residents and several faculty members, all from the Medical Sciences Campus of the University of Puerto Rico (n = 50). A demographic survey and a 6-item pre- and post-test on anal cancer were given to assess knowledge change. Thirty-four participants (68%) answered the survey. Mean age was 29.6 +/- 6.6 years; 78.8% had not received training in anal cancer screening, 93.9% reported being interested in receiving anal cancer training, and 75.8% expressed an interest in leading or conducting a clinical trial. A significant increase in the test scores was observed after the educational activity (pre-test: 3.4 +/- 1.2; post-test: 4.7 +/- 0.71). Three of the items showed an increase in knowledge by the time the post-test was taken. The first of these items assessed the participants' knowledge regarding the existence of any guidelines for the screening/treatment of patients with human papillomavirus (HPV)-related anal disease. The second of these items attempted to determine whether the participants recognized that anal intraepithelial neoplasia (AIN) 2 is considered to be a high-grade neoplasia. The last of the 3 items was aimed at ascertaining whether or not the participants were aware that warty growths in the anus are not necessarily a manifestation of high-grade AIN. This educational activity increased the participants' knowledge of anal cancer and revealed, as well, that most of the participants were interested in future training and in collaborating in a clinical trial. Training physicians from Puerto Rico on anal cancer clinical trials is essential to encourage recruitment of Hispanic patients in these studies now that the guidelines in anal cancer screening and treatment are on their way to be defined.

A 38-year-old white man had a 10-year history of human immunodeficiency virus (HIV) infection (A3), with no episodes of opportunistic diseases and in good immunologic recovery (CD4 cell count: 450 and indetectable HIV viral load) while on HAART. He presented with a two-month history of mild anal symptoms, including pruritus and episodic bleeding. He referred past episodes of anal warts, self-treated with several topical compounds, all proven unsuccessful. Perianal examination showed erythema and scratching. A 0.5cm sized tumor, with infiltration at the base was detected on digital exam, located at 15mm from the anal margin. Local biopsy driven by high-resolution anuscopy (AAR) yielded a final diagnosis of infiltrative epidermoid carcinoma. Might that neoplasia have been prevented? Copyright © 2013 Elsevier España, S.L.

[Necessary and unnecessary treatment options for hemorrhoids].

PubMed

Zindel, Joel; Inglin, Roman; Brügger, Lukas

2014-12-01

Up to one third of the general population suffers from symptoms caused by hemorrhoids. Conservative treatment comes first unless the patient presents with an acute hemorrhoidal prolapse or a thrombosis. A fiber enriched diet is the primary treatment option, recommended in the perioperative period as well as a long-term prophylaxis. A timely limited application of topical ointments or suppositories and/or flavonoids are further treatment options. When symptoms persist interventional procedures for grade I-II hemorrhoids, and surgery for grade III-IV hemorrhoids should be considered. Rubber band ligation is the interventional treatment of choice. A comparable efficacy using sclerosing or infrared therapy has not yet been demonstrated. We therefore do not recommend these treatment options for the cure of hemorrhoids. Self-treatment by anal insertion of bougies is of lowrisk and may be successful, particularly in the setting of an elevated sphincter pressure. Anal dilation, sphincterotomy, cryosurgery, bipolar diathermy, galvanic electrotherapy, and heat therapy should be regarded as obsolete given the poor or missing data reported for these methods. For a long time, the classic excisional hemorrhoidectomy was considered to be the gold standard as far as surgical procedures are concerned. Primary closure (Ferguson) seems to be superior compared to the "open" version (Milligan Morgan) with respect to postoperative pain and wound healing. The more recently proposed stapled hemorrhoidopexy (Longo) is particularly advisable for circular hemorrhoids. Compared to excisional hemorrhoidectomy the Longo-operation is associated with reduced postoperative pain, shorter operation time and hospital stay as well as a faster recovery, with the disadvantage though of a higher recurrence rate. Data from Hemorrhoidal Artery Ligation (HAL)-, if appropriate in combination with a Recto-Anal Repair (HAL/RAR)-, demonstrates a similar trend towards a better tolerance of the procedure at the expense of a higher recurrence rate. These relatively "new" procedures equally qualify for the treatment of grade III and IV hemorrhoids, and, in the case of stapled hemorrhoidopexy, may even be employed in the emergency situation of an acute anal prolapse. While under certain circumstances different treatment options are equivalent, there is a clear specificity with respect to the application of those procedures in other situations. The respective pros and cons need to be discussed separately with every patient. According to their own requirements a treatment strategy has to be defined according to their individual requirements.

We present a case in which chemoradiation therapy was effective in a geriatric patient with Stage IV anal canal cancer. The patient is an 81-year-old woman who complained of proctorrhagia and anal pain. She was referred to us by her family doctor who suspected rectal cancer. Tumors as large as 6.5 cm in diameter mainly on the right side of the rectum as well as 2 palpable enlarged lymph nodes on the right inguinal area, were found during the initial physical examination. Squamous cell carcinoma was elevated to 16 ng/mL. A CT scan revealed that irregularly shaped masses as large as 7 cm in diameter were externally exposed on the right side of the rectum along with enlarged lymph nodes on the right inguinal area and metastasis at S7 lesion in the liver. Squamous cell carcinoma was diagnosed from biopsy results. Due to her age, the chemotherapy regimen was S-1+CDDP with radiation therapy and 4-port irradiation (50.4 Gy) of the primary tumor, interior of the pelvis, and inguinal lymph nodes. Partial response was observed upon completion of treatment, and complete response was obtained after 6 months. She is currently an outpatient taking S-1: 60 mg/day orally. There is no indication of cancer recurrence after 1 year and 3 months, and she continues to visit an outpatient clinic for regular follow-ups. These results demonstrate the effectiveness of chemoradiation therapy for geriatric patients with Stage IV anal canal cancer.

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 dosimetricmore » 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 implies that anal wall and rectal wall should be considered separate organs in radiotherapy planning.« less

Aetiologically linked to HPV infection, malignancies of the anal canal have substantially increased in incidence over the last 20 years. Although most anal squamous cell carcinomas (SCCs) respond well to chemoradiotherapy, about 30% of patients experience a poor outcome, for undetermined reasons. Despite cumulative efforts for discovering independent predictors of overall survival, both nodal status and tumour size are still the only reliable factors predicting patient outcome. Recent efforts have revealed that the biology of HPV-related lesions in the cervix is strongly linked to the originally infected cell population. To address the hypothesis that topography also influences both gene expression profile and behaviour of anal (pre)neoplastic lesions, we correlated both proteomic signatures and clinicopathological features of tumours arising from two distinct portions of the anal canal: the lower part (squamous zone) and the more proximal anal transitional zone. Although microdissected cancer cells appeared indistinguishable by morphology (squamous phenotype), unsupervised clustering analysis of the whole proteome significantly highlighted the heterogeneity that exists within anal canal tumours. More importantly, two region-specific subtypes of SCC were revealed. The expression profile (sensitivity/specificity) of several selected biomarkers (keratin filaments) further confirmed the subclassification of anal (pre)cancers based on their cellular origin. Less commonly detected compared to their counterparts located in the squamous mucosa, SCCs originating in the transitional zone more frequently displayed a poor or basaloid differentiation, and were significantly correlated with reduced disease-free and overall survivals. Taken together, we present direct evidence that anal canal SCC comprises two distinct entities with different cells of origin, proteomic signatures, and survival rates. This study forms the basis for a dualistic classification of anal carcinoma, with implications for management, outcome expectations, and possibly therapy.

Background Manitoba-oculo-tricho-anal (MOTA) syndrome is a rare condition defined by eyelid colobomas, cryptophthalmos and anophthalmia/ microphthalmia, an aberrant hairline, a bifid or broad nasal tip, and gastrointestinal anomalies such as omphalocele and anal stenosis. Autosomal recessive inheritance had been assumed because of consanguinity in the Oji-Cre population of Manitoba and reports of affected siblings, but no locus or cytogenetic aberration had previously been described. Methods and results This study shows that MOTA syndrome is caused by mutations in FREM1, a gene previously mutated in bifid nose, renal agenesis, and anorectal malformations (BNAR) syndrome. MOTA syndrome and BNAR syndrome can therefore be considered as part of a phenotypic spectrum that is similar to, but distinct from and less severe than, Fraser syndrome. Re-examination of Frem1bat/bat mutant mice found new evidence that Frem1 is involved in anal and craniofacial development, with anal prolapse, eyelid colobomas, telecanthus, a shortened snout and reduced philtral height present in the mutant mice, similar to the human phenotype in MOTA syndrome. Conclusions The milder phenotypes associated with FREM1 deficiency in humans (MOTA syndrome and BNAR syndrome) compared to that resulting from FRAS1 and FREM2 loss of function (Fraser syndrome) are also consistent with the less severe phenotypes resulting from Frem1 loss of function in mice. Together, Fraser, BNAR and MOTA syndromes constitute a clinically overlapping group of FRAS–FREM complex diseases. PMID:21507892

To prospectively assess the efficacy and safety of stapled trans-anal rectal resection (STARR) compared to standard conservative treatment, and whether preoperative symptoms and findings at defecography and anorectal manometry can predict the outcome of STARR. Thirty patients (Female, 28; age: 51 ± 9 years) with rectocele or rectal intussusception, a defecation disorder, and functional constipation were submitted for STARR. Thirty comparable patients (Female, 30; age 53 ± 13 years), who presented with symptoms of rectocele or rectal intussusception and were treated with macrogol, were assessed. Patients were interviewed with a standardized questionnaire at study enrollment and 38 ± 18 mo after the STARR procedure or during macrogol treatment. A responder was defined as an absence of the Rome III diagnostic criteria for functional constipation. Defecography and rectoanal manometry were performed before and after the STARR procedure in 16 and 12 patients, respectively. After STARR, 53% of patients were responders; during conservative treatment, 75% were responders. After STARR, 30% of the patients reported the use of laxatives, 17% had intermittent anal pain, 13% had anal leakage, 13% required digital facilitation, 6% experienced defecatory urgency, 6% experienced fecal incontinence, and 6% required re-intervention. During macrogol therapy, 23% of the patients complained of abdominal bloating and 13% of borborygmi, and 3% required digital facilitation. No preoperative symptom, defecographic, or manometric finding predicted the outcome of STARR. Post-operative defecography showed a statistically significant reduction (P < 0.05) of the rectal diameter and rectocele. The post-operative anorectal manometry showed that anal pressure and rectal sensitivity were not significantly modified, and that rectal compliance was reduced (P = 0.01). STARR is not better and is less safe than macrogol in the treatment of defecation disorders. It could be considered as an alternative therapy in patients unresponsive to macrogol.

Expression of PDGFR-β and Kit in canine anal sac apocrine gland adenocarcinoma using tissue immunohistochemistry.

PubMed

Brown, R J; Newman, S J; Durtschi, D C; Leblanc, A K

2012-03-01

Canine anal sac apocrine gland adenocarcinoma (ASAGAC) is an uncommon but highly invasive and metastatic malignancy. Toceranib phosphate (Palladia) is a receptor tyrosine kinase (RTK) inhibitor that targets several members of the split kinase RTK family. These membrane receptors are important for cell cycling, apoptosis and angiogenesis, all of which can contribute to carcinogenesis. The objective of this study was to evaluate archived, paraffin-embedded canine ASAGAC and normal canine anal sacs for immunohistochemical detection of Kit and platelet-derived growth factor receptor beta (PDGFR-β). Two of 77 neoplasms (2.6%) expressed Kit. Fifteen of the neoplasms (19.5%) were positive for PDGFR-β expression. None of the normal canine anal sac epithelium expressed Kit or PDGFR-β. Because of these results, further investigation should be considered to determine the role of RTKs in the clinical course and treatment of canine ASAGAC. © 2011 Blackwell Publishing Ltd.

This report defines criteria and reviews the epidemiology, pathophysiology, and management of the following common anorectal disorders: fecal incontinence (FI), functional anorectal pain, and functional defecation disorders. FI is defined as the recurrent uncontrolled passage of fecal material for at least 3 months. The clinical features of FI are useful for guiding diagnostic testing and therapy. Anorectal manometry and imaging are useful for evaluating anal and pelvic floor structure and function. Education, antidiarrheals, and biofeedback therapy are the mainstay of management; surgery may be useful in refractory cases. Functional anorectal pain syndromes are defined by clinical features and categorized into 3 subtypes. In proctalgia fugax, the pain is typically fleeting and lasts for seconds to minutes. In levator ani syndrome and unspecified anorectal pain, the pain lasts more than 30 minutes, but in levator ani syndrome there is puborectalis tenderness. Functional defecation disorders are defined by ≥2 symptoms of chronic constipation or irritable bowel syndrome with constipation, and with ≥2 features of impaired evacuation, that is, abnormal evacuation pattern on manometry, abnormal balloon expulsion test, or impaired rectal evacuation by imaging. It includes 2 subtypes: dyssynergic defecation and inadequate defecatory propulsion. Pelvic floor biofeedback therapy is effective for treating levator ani syndrome and defecatory disorders.

Transanal haemorrhoidal dearterialization (THD) is increasingly perceived as an effective and better tolerated alternative to excisional haemorrhoidectomy. The aim of this study was to evaluate outcomes and the patient experience of THD in an Australian population with grade III or IV haemorrhoids. A retrospective review of prospectively maintained database on patients who had undergone THD over a 3-year period was performed. Data were collected on demographics, operative data, complications, recurrences and readmissions, postoperative pain and further interventions. Patient perceptions and satisfaction with the procedure were assessed with a telephone survey. A total of 85 patients with a mean age of 55 (±14) years with grade III (85%) or grade IV (15%) haemorrhoids underwent THD. Indications for surgery were predominantly bleeding (87%) and prolapse (41%). Median outpatients follow-up was 42 days and median telephone follow-up was 802 days. Median operating time was 25 min (±12). Twenty-four per cent of patients suffered complications, including postoperative bleeding (7%), constipation (7%), local sepsis (6%), anal fissure (5%) and temporary incontinence (2%). Severe postoperative pain occurred in 16% of the patients. The symptom recurrence rate was 19% and reintervention rate was 14%. About 98.8% of patients reported good or excellent overall satisfaction with the procedure. THD is a relatively new technique for the treatment of haemorrhoids, which is increasingly being used as an alternative to excisional haemorrhoidectomy. This study shows that patients' satisfaction with THD is high despite a moderate complication and recurrence rate and significant incidence of postoperative pain. © 2014 Royal Australasian College of Surgeons.

Sphincter-sparing radiotherapy or chemoradiation (RT/CRT) have become the standard treatments for most patients with anal cancer. Unfortunately, long-term survivors often suffer from severe bowel symptoms indicating sensory dysfunction. The aim of the present study was to characterize the sensory pathways of the brain-gut axis after radiotherapy for anal cancer. Cortical evoked potentials (CEPs) were recorded during repeated, rapid balloon distensions of the rectum and anal canal in 13 patients with anal cancer treated with radiotherapy or chemoradiation and in 17 healthy volunteers. Latencies and amplitudes of rectal CEPs were compared between the groups. CEPs from both rectal and anal distensions were examined using single sweep spectral band analysis to determine the relative amplitude of five spectral bands as a proxy of neuronal processing. Groups were comparable by age (62.4 ± 7.8 vs 58.9 ± 8.9, p < 0.32) and gender. Patients had a mean Wexner fecal incontinence score of 5.5 (±3.8) and median LARS Score of 29 (0-39). Rectal CEP latencies were prolonged in patients (F = 11.7; p < 0.001), whereas amplitudes were similar (F = 0.003; p = 0.96). Spectral analysis of CEPs from rectal distensions showed significant differences between groups in theta (4-8 Hz), alpha (8-12 Hz), beta (12-32 Hz) and gamma (32-70 Hz) bands (all p < 0.001) and CEPs from anal distensions showed significant differences in the alpha, beta and gamma bands (all p ≤ 0.002). Patients treated with RT/CRT for anal cancer have impaired ano-rectal sensory pathways and abnormal cortical processing. This may play a central role for the pathogenesis of late proctopathy.

The aim of this study was to perform a psychometric evaluation of the Fecal Incontinence Quality of Life Scale in the Spanish language. Eleven hospitals in Spain participated in the study, which included 118 patients with active fecal incontinence. All the patients filled out a questionnaire on the severity of their incontinence, a general questionnaire of health (Medical Outcomes Survey Short Form), and a Spanish translation of the Fecal Incontinence Quality of Life Scale (Cuestionario de Calidad de Vida de Incontinencia Anal), which consists of 29 items in four domains: lifestyle, behavior, depression, and embarrassment. On a second visit, patients repeated the Fecal Incontinence Quality of Life Scale. For each domain, an evaluation was made of temporal reliability, internal reliability, the convergent validity with the generic questionnaire of health, and the discriminant validity correlating the domains of Cuestionario de Calidad de Vida de Incontinencia Anal with the severity of fecal incontinence. For cultural adaptation, the answer alternatives for 14 items were modified. A total of 111 patients (94 percent) completed the study adequately. Temporal reliability (test-retest) was good for all domains except for embarrassment, which showed significant differences (P < 0.02). Internal reliability was good/excellent for all domains (Cronbach alpha >0.80, between 0.84 and 0.96). The four domains of Cuestionario de Calidad de Vida de Incontinencia Anal significantly correlated with the domains of the generic questionnaire on health (P < 0.01) and with the scale of severity of fecal incontinence (P < 0.001). All domains of Cuestionario de Calidad de Vida de Incontinencia Anal correlated negatively with the need to wear pads (P < 0.01) and with the presence of complete fecal incontinence. The Cuestionario de Calidad de Vida de Incontinencia Anal incorporates sufficient requirements of reliability and validity to be applied to patients with fecal incontinence.

To evaluate the frequency and spectrum of lesions of different pelvic floor muscles at endoanal MRI in women with severe faecal incontinence and to study their relation with incontinence severity and manometric findings. In 105 women MRI examinations were evaluated for internal anal sphincter (IAS), external anal sphincter (EAS), puborectal muscle (PM) and levator ani (LA) lesions. The relative contribution of lesions to differences in incontinence severity and manometric findings was studied. IAS (n = 59) and EAS (n = 61) defects were more common than PM (n = 23) and LA (n = 26) defects. PM and LA defects presented mainly with IAS and/or EAS defects (isolated n = 2 and n = 3). EAS atrophy (n = 73) was more common than IAS (n = 19), PM (n = 16) and LA (n = 9) atrophy and presented mainly isolated. PM and LA atrophy presented primarily with EAS atrophy (isolated n = 3 and n = 1). Patients with IAS and EAS lesions had a lower resting and squeeze pressure, respectively; no other associations were found. PM and LA lesions are relatively common in patients with severe faecal incontinence, but the majority of lesions are found in women who also have IAS and/or EAS lesions. Only an association between anal sphincter lesions and manometry was observed.

This study examined the relationship between prescription drug misuse and sexual risk behaviors (i.e. unprotected sex, increased number of sex partners) in a sample of young men who have sex with men (YMSM) in Philadelphia. Data come from a cross-sectional study of 18-29 year old YMSM (N=191) who misused prescription drugs in the past 6 months. Associations were investigated in two regression models: logistic models for unprotected anal intercourse (UAI) and zero-truncated Poisson regression model for number of sex partners. Of 177 participants engaging in anal intercourse in the past 6 months, 57.6% engaged in UAI. After adjusting for socio-demographic variables and illicit drug use, misuse of prescription pain pills and muscle relaxants remained significantly associated with engaging in receptive UAI. No prescription drug class was associated with a high number of sex partners. This study provides additional evidence that some prescription drugs are associated with sexual risk behaviors among YMSM. PMID:25240627

Fecal incontinence after the surgical repair of Hirschsprung disease is a potentially preventable complication that carries a negative impact on patient's quality of life. Patients that were previously operated for Hirschsprung disease and presented to our bowel management clinic with the complaint of fecal incontinence were retrospectively reviewed. All patients underwent a rectal examination under anesthesia looking for anatomic explanations for their incontinence. One hundred three patients were identified. 54 patients had a damaged anal canal. 22 patients also had a patulous anus. The operative reports mentioned the pectinate line in 32 patients, in 12 it was not mentioned, and in 10 patients the operative report was not available. All patients with a damaged anal canal suffered from true fecal incontinence; 45 of them are on daily enemas (41 are clean and 4 are still having "accidents"), 7 are not doing bowel management due to noncompliance and 2 patients have a permanent ileostomy. 49 patients did not have a damaged anal canal, 25 of those responded to changes in diet and medication and are having voluntary bowel movements. Fecal incontinence may occur after an operation for Hirschsprung disease. When the anal canal is damaged, incontinence is always present, severe, and probably permanent. The preservation of the anal canal may avoid this complication. Copyright © 2017. Published by Elsevier Inc.

Physiologic study of the terminal digestive tract in chronic painful constipation.

Meunier, P

A manometric study of the sigmoid colon and of the anorectum was undertaken in 65 chronically constipated patients complaining of abdominal pain, and in a control group of 23 healthy volunteers. Rectal compliance was tested in both groups. The sigmoid motility study allowed for the segregation of the constipated patients into three groups: hypokinesia (12 cases), normokinesia (34 cases), hyperkinesia (19 cases). Rectal manometry showed anal hypertony in 24 patients, impaired rectal conscious sensitivity in 12 subjects, and normal functions in the remaining cases. The rectal compliance study disclosed a decreased compliance in 15 cases and increased compliance in 13 other patients. In 12 cases disordered sigmoid motility was the only abnormality; in 10 cases only a rectoanal abnormality was found. Most of the patients (52%) exhibited miscellaneous disorders. In contrast, all parameters were normal in nine subjects. No consistent pattern of motility disorders was thus demonstrated in this clinically homogeneous group of patients with chronic, painful, constipation. PMID:3758814

Closing the internal opening by a clip ovesco has been recently proposed for healing the fistula tract, but, to date, data on benefit are poorly analyzed. The aim was to report a preliminary multicenter experience. Retrospective study was undertaken in six different French centers: surgical procedure, immediate complications, and follow-up have been collected. Nineteen clips were inserted in 17 patients (M/F, 4/13; median age, 42 years [29-54]) who had an anal fistula: 12 (71%) high fistulas (including 4 rectovaginal fistulas), 5 (29%) lower fistulas (with 3 rectovaginal fistulas), and 6 (35%) Crohn's fistulas. Out of 17 patients, 15 had a seton drainage beforehand. The procedure was easy in 8 (47%) patients and the median operative time was 27.5 min (20-36.5). Postoperative period was painful for 11 (65%) patients. A clip migration was noted in 11 patients (65%) after a median follow-up of 10 days (5.5-49.8). Eleven patients (65%) who failed had reoperation including 10 new drainages within the first month (0.5-5). After a mean follow-up of 4 months (2-7),, closing the tract was observed in 2 patients (12%) following the first insertion of the clip and in another one after a second insertion. Treatment of anal fistula by placing a clip on the internal opening is disappointing and deleterious for some patients. A better assessment before dissemination is recommended.

Creation of an animal model of necrotizing enterocolitis (NEC) allowing adjustment of severity and potential recoverability is needed to study effectiveness of prevention and treatment strategies. This study describes a novel model in preterm rabbits capable of adjusting severity of NEC-like histologic changes. Rabbit pups (n = 151) were delivered by cesarean section 2 days preterm. In the treatment groups, tissue adhesive was applied to anal openings to simulate the poor intestinal function and dysmotility of preterm neonates. Pups were placed into five groups: 3INT (3 day intermittent block), 4INT (4 day intermittent block), 3COM (3 day complete block), 4COM (4 day complete block), based on differences in type of anal blockage and day of life sacrificed. The fifth group, 4CON, was comprised of a control arm (n = 28) without anal block, with sacrifice of subjects on day 4. All pups were gavage fed with formula contaminated with Enterobacter cloacae, ranitidine, and indomethacin. Following sacrifice, the intestines were harvested for pathologic evidence of NEC. A blinded pathologist graded histologic changes consistent with NEC using a grading scale 0-4 with 4 being most severe. Fifty-seven pups (57/123) (46%) in the research arm survived to sacrifice, compared to 26/28 (93%) in the control arm of the investigation, p < 0.0001. The incidence and severity of NEC-like damage increased with the duration and completeness of the anal blockage. 44/57 (77%) of survivors revealed various degrees of NEC-like damage to large and small bowel, and 3/26 (12%) exhibited early NEC-like mucosal injury in the research and control arms, respectively. This animal model produces NEC-like pathologic changes in both small and large intestine in preterm rabbits. Because incidence and severity of damage increases with duration and completeness of intestinal dysmotility, this allows future effectiveness studies for nonsurgical treatment and prevention of NEC.

Hidradenitis suppurativa (HS) is a chronic, inflammatory, and recurrent skin disease. Surgical excision of wounds appears to be the only curative treatment for the prevention of recurrence of moderate to severe stages. Magnetic resonance imaging (MRI) is a standard reference examination for the detection of HS peri-anal inflammatory fistula. In this case study, the use of real-time medical infrared thermography, in combination with MRI as appropriate imaging, is proposed. The aim is to assist surgeons in the pre- and peri-surgical management of severe perianal hidradenitis suppurativa with the intent to ensure that all diseased lesions were removed during surgery and therefore to limit recurrence. The results show that medical infrared thermography (MIT), coupled with MRI, could be highly effective strategy to address thermally distinguished health tissues and inflammatory sites during excision, as characterised by differential increases in temperature. Medical infrared thermography could be used to check the total excision of inflammatory lesions as a noninvasive method that is not painful, not radiant, and is easily transportable during surgery. Ultimately, this method could be complementary with MRI in providing clinicians with objective data on the status of tissues below the perianal skin surface in the pre- and per-operating management of severe hidradenitis suppurativa.

Long, Kevin C; Menon, Raman; Bastawrous, Amir; Billingham, Richard

2016-03-01

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology. Patients with lesions should undergo history and physical exam including digital rectal exam and standard anoscopy. High-resolution anoscopy can be considered as well, although it is of questionable time and cost-effectiveness. Nonoperative treatments include expectant surveillance and topical imiquimod or 5-fluorouracil. Operative therapies include wide local excision and targeted ablation with electrocautery, infrared coagulation, or cryotherapy. Recurrence rates remain high regardless of treatment delivered and surveillance is paramount, although optimal surveillance regimens have yet to be established.

The small Indian mongoose (Herpestes auropunctatus) is an invasive species in Okinawa and Amami-Oshima, Japan. Major strategies for their eradication have been the use of baited traps, which suffer from decreasing efficiency with declining populations and the bycatch of native animals. To address these concerns, mongoose-specific lures are required. In this study, we aimed to identify species- and/or sex-specific compounds from anal sac secretions of small Indian mongooses. Volatile compounds emitted from male and female mongoose anal sac secretions were analyzed by thermal desorption-gas chromatography-mass spectrometry. In addition to several fatty acids, 2-phenylethanol was identified as a minor compound, which is uncommon in mammalian secretions but a dominant odorant in roses. Female samples emitted higher levels of 2-phenylethanol than male samples did. These findings indicate that 2-phenylethanol is a female-specific volatile compound of anal sac secretions in small Indian mongooses, and it may be useful as an ingredient of mongoose-specific scent lures.

Sonographic assessment of the anal sphincter after obstetric anal sphincter injury (OASI) using transperineal ultrasound (TPUS).

PubMed

Eisenberg, Vered H; Valsky, Dan V; Yagel, Simcha

2018-03-24

Obstetric anal sphincter injury (OASI) is the most common cause of anal incontinence and ano-rectal symptoms in women 1 . Reported rates of anal incontinence following primary repair of OASI range between 15-61%, with a mean of 39% 2, 3 . Other possible complications of OASI include perineal pain, dyspareunia, and less commonly, abscess formation, wound breakdown, and rectovaginal fistulae. Symptom onset may occur immediately, several years postpartum, or only late in life when aging of tissues adds to the delivery insult. Having sustained an OASI may impact significantly on women's physical and emotional health. Missed OASI, inadequate repair or lack of follow up are potential sources of litigation 4 . The reported incidence of OASI may be as high as 4-6.6% 4 , averaging 2.9% in the UK 3 . The incidence is higher in primiparae (6.1%) than in multiparae (1.7%) 3 . Recent years are seeing an increased awareness and structured training programs, which appear to have resulted in an increase in the detection rate of OASI 3 . The following risk factors have been identified with varying risk rates reported 3 : Asian ethnicity (OR 2.27, 95% CI 2.14-2.41), nulliparity (relative risk [RR] 6.97, 95% CI 5.40-8.99), birth weight greater than 4 kg (OR 2.27, 95% CI 2.18-2.36), shoulder dystocia (OR 1.90, 95% CI 1.72-2.08), occipito-posterior position (RR 2.44, 95% CI 2.07-2.89), prolonged second stage of labor (up to RR 2.02, 95% CI 1.62-2.51 after four hours duration). Instrumental deliveries and episiotomy use have been extensively studied resulting in the following evidence: Vacuum delivery without episiotomy (OR 1.89, 95% CI 1.74-2.05); vacuum delivery with episiotomy is protective (OR 0.57, 95% CI 0.51-0.63); forceps delivery without episiotomy carries the highest potential risk (OR 6.53, 95% CI 5.57-7.64); and forceps delivery with episiotomy (OR 1.34, 95% CI 1.21-1.49). Other potential risk factors have been suggested with varying evidence such as advanced maternal age at first birth, Asian race, a vaginal birth after cesarean, and type of obstetrical care provider 4 . Possible protective factors include obesity, perineal massage (RR 0.91, 95% CI 0.86-0.96) 5 , perineal protection at crowning 3 , warm compression during the second stage of labor (RR 0.48, 95% CI 0.28-0.84) 3 , mediolateral episiotomy in instrumental deliveries 6 , a wide angle of the mediolateral episiotomy (at least 60 degrees away from the midline when the perineum is distended) 7 , and pre-labor cesarean section 4 . However, clinicians and patients alike should be aware that risk factors do not allow the accurate prediction of OASI 3 . OASI is usually diagnosed in the immediate postpartum period. The classification is based on the extent of lacerations to the external and internal anal sphincter (EAS and IAS, respectively) and epithelium as devised by Sultan 2,3,8 (Figure 1) and adopted by the World Health Organization (WHO). The degree of damage impacts on the development of symptoms, with 3C and 4 th degree tears carrying a graver prognosis than 3A and 3B tears 9 . It is not unusual for a tear to be missed in the labor ward: the reported rates of missed OASI range from 26-87% 10 . Since all women having a vaginal delivery are at risk of sustaining OASI, they should be examined systematically, including a digital rectal examination, to assess the severity of damage, prior to suturing 3 .

This study was designed to assess the safety, efficacy, and postoperative outcomes of partial stapled hemorrhoidopexy (PSH). A prospective study was conducted between February and March 2010. PSH was performed with single-window anoscopes for single isolated hemorrhoids, bi-window anoscopes for two isolated hemorrhoids, and tri-window anoscopes for three isolated hemorrhoids or circumferential hemorrhoids. The data pertaining to demographics, preoperative characteristics and postoperative outcomes were collected and analyzed. Forty-four eligible patients underwent PSH. Single-window anoscopes were used in 2 patients, and bi- and tri-window anoscopes in 6 and 36 patients. The blood loss in patients with single-window, bi-window, and tri-window anoscopes was 6.0 ml (range 5.0-7.0 ml), 5.0 ml (range 5.0-6.5 ml), and 5.0 ml (4.5-14.5 ml) (P = 0.332). The mean postoperative visual analog scale score for pain was 3 (range, 1-4), 2 (range 1-4), 3 (range 2-6), 1 (range 0-3), 1 (range 0-2) and 2 (range 2-4) at 12 h, days 1, 2, 3, and 7, and at first defecation. The rate of urgency was 9.1%. No patients developed anal incontinence or stenosis. The 1-year recurrence rate of prolapsing hemorrhoids was 2.3%. Partial stapled hemorrhoidopexy appears to be a safe and effective technique for grade III-IV hemorrhoids. Encouragingly, PSH is associated with mild postoperative pain, few urgency episodes, and no stenosis or anal incontinence.

Radiosurgical fistulotomy; an alternative to conventional procedure in fistula in ano.

Most surgeons continue to prefer the classic lay open technique [fistulotomy] as the gold standard of treatment in anal fistula. In this randomized study, a comparison is made between conventional fistulotomy and fistulotomy performed by a radio frequency device. One hundred patients of low anal fistula posted for fistulotomy were randomized prospectively to either a conventional or radio frequency technique. Parameters measured included time taken for the procedure, amount of blood loss, postoperative pain, return to work, and recurrence rate. The patient demographic was comparable in 2 groups. The radio frequency fistulotomy was quicker as compared to a conventional one [22 versus 37 minutes, p = 0.001], amount of bleeding was significantly less [47 ml versus 134 ml, p = 0.002], and hospital stay was less when patient was operated by radio frequency method [37 hours versus 56 hours in conventional method, p = 0.001]. The postoperative pain in the first 24 hours was more in conventional group [2 to 5 versus 0 to 3 on visual analogue scale]. The patients from radio frequency group resumed their duties early with a reduced healing period of the wounds [47 versus 64 days, p = 0.01]. The recurrence or failure rates were comparable in the radio frequency and conventional groups [2% versus 6%]. Fistulotomy procedure using a radio frequency technique has significant advantages over a conventional procedure with regard to operation time, blood loss, return to normal activity, and healing time of the wound.

Hemorrhoids and anal fissures in inflammatory bowel disease.

Perianal disease is a common complication of inflammatory bowel disease (IBD). It includes different conditions from more severe and potentially disabling ones, such as abscesses and fistulas, to more benign conditions such as hemorrhoids, skin tags and fissures. Most literature has been focused on anal sepsis and fistulae, as they carry the majority of disease burden and often alter the natural course of the disease. Hemorrhoids and anal fissures in patients with IBD have been overlooked, although they can represent a challenging problem. The management of hemorrhoids and fissures in IBD patients may be difficult and may significantly differ compared to the non-affected population. Historically surgery was firmly obstructed, and hemorrhoidectomy or sphincterotomy in patients with associated diagnosis of IBD was considered harmful, although literature data is scant and based on small series. Various authors reported an incidence of postoperative complications higher in IBD than in the general populations, with potential severe events. Considering that a spontaneous healing is possible, the first line management should be a medical therapy. In patients non-responding to conservative measures it is possible a judicious choice of surgical options on a highly selective basis; this can lead to acceptable results, but the risk of possible complications needs to be considered. In this review it is analyzed the current literature on the incidence, symptoms and treatment options of hemorrhoids and anal fissures in patients with Crohn's disease and ulcerative colitis.

Conditional trans-rectal stimulation of the pudendal nerve could provide a viable solution to treat hyperreflexive bladder in spinal cord injury. A set threshold of the amplitude estimate of the external anal sphincter surface electromyography (sEMG) may be used as the trigger signal. The efficacy of such a device should be tested in a large scale clinical trial. As such, a probe should remain in situ for several hours while patients attend to their daily routine; the recording electrodes should be designed to be large enough to maintain good contact while observing design constraints. The objective of this study was to arrive at a design for intra-anal sEMG recording electrodes for the subsequent clinical trials while deriving the possible recording and processing parameters. Having in mind existing solutions and based on theoretical and anatomical considerations, a set of four multi-electrode probes were designed and developed. These were tested in a healthy subject and the measured sEMG traces were recorded and appropriately processed. It was shown that while comparatively large electrodes record sEMG traces that are not sufficiently correlated with the external anal sphincter contractions, smaller electrodes may not maintain a stable electrode tissue contact. It was shown that 3 mm wide and 1 cm long electrodes with 5 mm inter-electrode spacing, in agreement with Nyquist sampling, placed 1 cm from the orifice may intra-anally record a sEMG trace sufficiently correlated with external anal sphincter activity. The outcome of this study can be used in any biofeedback, treatment or diagnostic application where the activity of the external anal sphincter sEMG should be detected for an extended period of time.

There is conflicting data in the literature regarding the risk of obstetric anal sphincter laceration in patients with a prior laceration. This retrospective chart review seeks to examine the risk of recurrence of obstetric anal sphincter lacerations. Patients who sustained anal sphincter laceration at delivery during a 13-year time period from January 1991 to December 2003 were identified from the medical records database at Temple University Hospital. All subsequent deliveries in this group of patients were extracted from the database. Chart review was performed on all subsequent deliveries with specific attention to demographic factors such as age, race, parity, etc., maternal weight, fetal weight, presence of maternal diabetes, and labor characteristics such as induction or augmentation of labor, instrumentation at delivery (vacuum or forceps), use of episiotomy, and degree of perineal laceration. There were 23 451 vaginal deliveries at Temple University Hospital between January 1, 1991 and December 31, 2003. Anal sphincter laceration was noted in 778 subjects. Subsequent deliveries among the group of patients with prior sphincter tears numbered 271. Six (2.4%) patients had recurrence of anal sphincter lacerations, and five of them were third degree lacerations. The rate of recurrent lacerations was not significantly different from the rate of initial lacerations (2.4% vs. 3.3%; odds ratio 0.72, 95% confidence interval 0.33-1.59; p = 0.4). Women who sustained recurrent lacerations were older, more obese (mean weight 92 kg vs. 82 kg), had larger babies (3506 g vs. 3227 g), and were more likely to have episiotomies (66.7% vs. 7%) or instrumental deliveries (33.3 vs. 6.5%). Prior anal sphincter laceration does not result in an increased rate of recurrence. Operative vaginal delivery particularly with episiotomy is a risk factor for both initial and recurrent laceration.

The aim of this work was to evaluate the role of human papillomavirus (HPV) testing and anal cytology, considering a population of HIV-positive and negative men who have sex with men (MSM), at high risk of sexually transmitted diseases (STD), in order to ascertain which of the methods examined is the best screening strategy for the prevention of anal cancer. In the period 06/2013-07/2014 at the "MTS Centre" of the University of Florence, 87 male patients, homo/bi-sexual, of which 46 HIV-negative and 41 HIV-positive, were recruited for anal Pap smear and HPV testing. All patients with an "abnormal" cytological result underwent anoscopy with possible biopsy. HPV testing was positive in 73 patients (83.6%). Cytology was negative in 50 patients (57.5%), inconclusive in 14 patients (16.1%), abnormal in 23 patients (26.4%): 14 ASC-US (19.2%), 4 ASC-H (5.5%), 5 L-SIL (6.8%), 0 H-SIL. Anoscopy with biopsy led to diagnosis of AIN I in 10 cases, of which 6 ASC-US+ and 4L-SIL+, AIN II in only 1 case, LS-IL+. Anal HPV testing, when used in primary screening, lead to a high number of "false positives", given the too high prevalence of HPV infection in MSM, the highest risk population targeted for screening. So we propose a screening program with anal cytology which has a high sensitivity for detection of AIN while is a poor predictor of the severity of these lesions; therefore, all patients with abnormal anal Pap smear should undergo anoscopy with biopsy.

Anal squamous proliferative lesions, including condyloma, anal high-grade squamous intraepithelial lesion (AHSIL) and squamous cell carcinoma (SCC), are associated with human papilloma virus (HPV) infection. The objectives of the study were to investigate the HPV prevalence of anal squamous proliferative lesion in Taiwan. From 1991 to 2005, 41 cases with condyloma, 12 cases with AHSIL, and 13 cases with SCC were collected. DNA was extracted from the tissue sections of these patients, and the HPV genotype was identified using polymerase chain reaction and gene chip. The integration status of HPV16 DNA was also evaluated by quantitative real-time polymerase chain reaction. Anal condyloma mainly occurred in young males, but AHSIL and anal SCC developed in older patients. In the patients with human immunodeficiency virus (HIV) infection, AHSIL developed much earlier than patients without HIV infection (36 vs. 61 years). HPV DNA was detected in all 56 patients whose specimens contained adequate DNA. High-risk HPVs (type 16, 58, etc.) were mainly detected in the AHSIL and SCC. Multiple HPV infection was found in AHSIL (4 of 12) and condyloma (11 of 34) but was rare in invasive cancer (1 of 12). Seven of 8 patients with HPV16 infection had coexistent episomal and integrated forms. HPV58 is a unique high-risk HPV prevalent in Taiwan. The integration status of HPV seems not correlated with the severity of the dysplasia. In our study, emerging HIV-positive AHSIL in recent years indicates that we should devote more efforts to promote sexual safety among the people who engaged in anal intercourse.

p16 is the most widely studied biomarker in lower anogenital tract squamous intraepithelial lesions and, currently the only recommended biomarker for histological grade assessment. The aim of this systematic review and meta-analysis was to evaluate p16-positive rates according to anal squamous intraepithelial lesions/anal intraepithelial neoplasia (AIN) grade. Two investigators independently searched four electronic databases: PubMed, Web of Sciences, Scopus, and Embase from inception until August 2017. Studies that evaluated p16 immunostaining in histological samples of anal and/or perianal squamous intraepithelial lesions and defined a p16-positive result as diffuse block staining with nuclear or nuclear plus cytoplasmic staining were included. A meta-analysis was performed using a random effects model. Fifteen studies consisting of 790 samples were included. The proportion of p16 expression increased with the severity of histological grade. p16 positivity was 2% (95% CI: 0.2-5%) in normal histology, 12% (95% CI: 2-27%) in low-grade squamous intraepithelial lesions (LSILs)/AIN1 (excluding condylomas), 7% (95% CI: 2-13%) in all LSIL (AIN1/LSIL/condyloma), 76% (95% CI: 61-88%) in AIN2, and 90% (95% CI: 82-95%) in AIN3. For anal high-grade squamous intraepithelial lesions (HSILs), in studies using a two-tiered nomenclature, p16 positivity was 84% (95% CI: 66-96%) and for all HSIL (AIN2, AIN3, HSIL combined) it was 82% (95% CI: 72-91%). In summary, p16 positivity in anal squamous intraepithelial lesions appears to be in a similar range to the commonly described cervical squamous intraepithelial lesions, however, for anal low-grade lesions positivity seems to be lower.

Purpose: Newer radiation techniques, and the application of continuous 5-FU exposure during radiation therapy using oral capecitabine may improve the treatment of anal cancer. This phase 1, dose-finding study assessed the feasibility and efficacy of simultaneous integrated boost–intensity modulated radiation therapy (SIB-IMRT) with concomitant capecitabine and mitomycin C in locally advanced anal cancer, including pharmacokinetic and pharmacogenetic analyses. Methods and Materials: Patients with locally advanced anal carcinoma were treated with SIB-IMRT in 33 daily fractions of 1.8 Gy to the primary tumor and macroscopically involved lymph nodes and 33 fractions of 1.5 Gy electively to the bilateral iliac and inguinalmore » lymph node areas. Patients received a sequential radiation boost dose of 3 × 1.8 Gy on macroscopic residual tumor if this was still present in week 5 of treatment. Mitomycin C 10 mg/m{sup 2} (maximum 15 mg) was administered intravenously on day 1, and capecitabine was given orally in a dose-escalated fashion (500-825 mg/m{sup 2} b.i.d.) on irradiation days, until dose-limiting toxicity emerged in ≥2 of maximally 6 patients. An additional 8 patients were treated at the maximum tolerated dose (MTD). Results: A total of 18 patients were included. The MTD of capecitabine was determined to be 825 mg/m{sup 2} b.i.d. The predominant acute grade ≥3 toxicities included radiation dermatitis (50%), fatigue (22%), and pain (6%). Fifteen patients (83% [95%-CI: 66%-101%]) achieved a complete response, and 3 (17%) patients a partial response. With a median follow-up of 28 months, none of the complete responders, and 2 partial responders had relapsed. Conclusions: SIB-IMRT with concomitant single dose mitomycin C and capecitabine 825 mg/m{sup 2} b.i.d. on irradiation days resulted in an acceptable safety profile, and proved to be a tolerable and effective treatment regimen for locally advanced anal cancer.« less

A case of a young male patient, who came to the Second Xiangya Hospital, Central South University because of snoring for 10 years and nocturnal gatism for half month, was analyzed retrospectively. He was diagnosed as obstructive sleep apnea hypopnea syndrome (OSAHS) finally. The patient had been diagnosed and treated as stroke in the local hospital, while urinary and anal incontinence were not relieved. It was a dilemma for him to be properly diagnosed and treated. Polysomnography in our hospital revealed apnea hypopnea index (AHI) at 44.7 events/h, oxygen desaturation index (ODI) at 70.8 events/h and the longest apnea time at 185 seconds while the lowest blood oxygen saturation reduced to 31%. In addition, 413 events of apnea accounted for 61.2% of the sleep time and the minimal heart rate was 23 times/min. The patient was diagnosed as severe OSAHS with hypoxia metabolic brain disease, moderate pulmonary arterial hypertension, secondary polycythemia and obesity hypoventilation syndrome finally. He received the treatment of positive airway pressure non-invasive ventilator with an average pressure at 11.7 cmH2O with reduced AHI and increased blood oxygen saturation. The urinary and anal incontinence disappeared during the first night of treatment and it has been totally resolved so far. We considered that gatism was secondary to OSAHS with severe hypoxia resulted from attenuated regulation of primary defecation in the night. Physicians should pay attention to OSAHS when accepting obese patients with nocturnal incontinence, obvious daytime sleepiness and night snoring. Urinary and anal incontinence could be completely disappeared under therapy of positive airway pressure.

Serum disposition of bovine lactoferrin after oral and anal administration and its proteolytic cleavage by gastric transit in rainbow trout (Oncorhynchus mykiss W.).

Several studies have shown an immunomodulatory effect of orally administered bovine lactoferrin (LF) in fish, but the process of digestion was not characterized. In the present study, we investigated the fate of bovine LF after oral and anal administration, and studied the appearance of intact LF in the bloodstream and its proteolytic attack during the gastric transit in rainbow trout (Oncorhynchus mykiss) held at 9 degrees C and 18 degrees C. Data obtained showed the presence of intact bovine LF in the bloodstream only after anal administration in fish held at 18 degrees C and the presence of several peptides derived from bovine LF in the gastric content. Immunoblotting analysis showed that only a part of bovine LF-derived peptides reacted with the applied anti-bovine LF antibody. The concentration of intact bovine LF, after 30 min of administration, in the gastric content of fish reared at 18 degrees C, being extremely low, if any, led us to suspect that the immunoregulatory effect of dietary bovine LF shown in fish by several authors is not due to the intact form but to bioactive fragments, originated by the proteolytic attack during the gastric transit, as demonstrated in higher vertebrates.

The aim of the present study was to examine the clinical value of ‘tying, binding and fixing operation’ in treating severe mixed hemorrhoids. A total of 160 patients with severe mixed hemorrhoids were selected and randomly divided into the experimental (n=80) and control (n=80) groups. The groups were treated using ‘tying, binding and fixing operation’ and Doppler ultrasound-guided hemorrhoidal artery ligation (DG-HAL), respectively. The results showed that the average operative time of the experimental group (35.57±6.17) was significantly higher than that of the control group (12.73±4.92). There was no significant difference of blood loss during the operation between the two groups (P>0.05). There was also no significant difference in improving the hemorrhage symptom between the two groups (P>0.05). In addition, concerning improvement of prolapse symptoms and reduction of the volume of hemorrhoids, the experimental group were significantly improved as compared to the control group. No anal function damage in the two groups was identified, and the length of stay in hospital for the two groups was not significantly different (P>0.05). However, the hospitalization cost in the experimental group (5,334.77±875.54) was significantly lower than that of the control group (8,551.81±1,806.54) and satisfaction degree was significantly higher than that of the control group. The incidences of perianal pain, anal edema and dysuria between two groups were not significantly different (P>0.05). There were 10 cases of secondary hemorrhage and 18 cases of infection in the experimental group, and 12 cases of secondary hemorrhage and 14 cases of infection in the control group, although the differences between the two groups were not statistically significant (P>0.05). The incidence rate of local hematoma in the experimental group (1.2%) was significantly lower than that in the control group (15.0%). The recurrence rate of the control group (22.5%) was also significantly higher than that of the experimental group (2.5%). In conclusion, tying, binding and fixing operation is a promising method that may be employed for the treatment of sever mixed hemorrhoids, and it is better than DG-HAL in improving the prolapse and reducing the volume of hemorrhoids.

Treatment for anal and rectal cancer (ARCa) often results in side effects that directly impact sexual functioning; however, ARCa survivors are an understudied group, and factors contributing to the sexual sequelae are not well understood. Body image problems are distressing and may further exacerbate sexual difficulties, particularly for women. This preliminary study sought to (1) describe body image problems, including sociodemographic and disease/treatment correlates, and (2) examine relations between body image and sexual function. For the baseline assessment of a larger study, 70 women completed the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire and Colorectal Cancer-specific Module, including the Body Image subscale, and Female Sexual Function Index. Pearson's correlation and multiple regression evaluated correlates of body image. Among sexually active women (n = 41), hierarchical regression examined relations between body image and sexual function domains. Women were on average 55 years old (standard deviation = 11.6), non-Hispanic White (79%), married (57%), and employed (47%). The majority (86%) reported at least one body image problem. Younger age, lower global health status, and greater severity of symptoms related to poorer body image (p's < 0.05). Poor body image was inversely related to all aspects of sexual function (β range 0.50-0.70, p's < 0.05), except pain. The strongest association was with Female Sexual Function Index Sexual/Relationship Satisfaction. These preliminary findings suggest the importance of assessing body image as a potentially modifiable target to address sexual difficulties in this understudied group. Further longitudinal research is needed to inform the development and implementation of effective interventions to improve the sexual health and well-being of female ARCa survivors.

Screening, Surveillance, and Treatment of Anal Intraepithelial Neoplasia

2016-01-01

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology. Patients with lesions should undergo history and physical exam including digital rectal exam and standard anoscopy. High-resolution anoscopy can be considered as well, although it is of questionable time and cost–effectiveness. Nonoperative treatments include expectant surveillance and topical imiquimod or 5-fluorouracil. Operative therapies include wide local excision and targeted ablation with electrocautery, infrared coagulation, or cryotherapy. Recurrence rates remain high regardless of treatment delivered and surveillance is paramount, although optimal surveillance regimens have yet to be established. PMID:26929753

Omentalization of cystic sublumbar lymph node metastases for long-term palliation of tenesmus and dysuria in a dog with anal sac adenocarcinoma.

A 13-year-old castrated male Bassett Hound was examined because of a 2-week history of severe constipation and tenesmus. Radiography revealed a large cystic mass in the caudal portion of the abdomen that was compressing the urethra and obstructing the pelvic canal. A small perianal mass was also noticed in the region of the left anal sac. Exploratory surgery was performed, but the mass was deemed unresectable. Instead, the mass was incised, drained, and omentalized in an attempt to establish continuous drainage after surgery. Cytologic evaluation of the perianal mass was consistent with a diagnosis of anal sac adenocarcinoma. Histologic evaluation of the abdominal mass revealed it was a lymph node effaced by adenocarcinoma. Despite the poor prognosis for anal sac adenocarcinoma with metastatic spread to the sublumbar lymph nodes, tenesmus and dysuria in this dog remained palliated until the dog's death 18 months after surgery. Omentalization was successful in providing a continuous method of fluid drainage for this cystopapillary abdominal tumor.

[Anorectal manifestations of sexually transmitted infections].

PubMed

Lautenschlager, Stephan

2013-07-01

The incidence of sexually transmitted infections is rising in Europe and in Switzerland since the beginning of the third millenium. Many organisms may affect the perianal skin and the anorectum. While some of these infections are a result of contigous spread from genital infection, most result from receptive anal intercourse affecting males who have sex with males but is seen increasingly in females as well since there is evidence of the increasing popularity of anal sex among heterosexuals. The symptoms of specific infections are largely dependent on the route and site of inoculation. Organisms that cause typical genital symptoms - such as syphilis, chancroid, herpes simplex or HPV-infection - result in similar symptoms when the perianal skin, the anoderm or the distal anal canal are the site of infection. Patients with proctitis may have unspecific signs in various degrees including mucous discharge, rectal bleeding, anorectal pain, superficial ulcers and sometimes generalized lymphadenopathy and fever. It is of utmost importance to include STIs (e. g. lymphogranuloma venereum, gonorrhea, non-LGV-chlamydia and herpes simplex) in the differential diagnosis in these patients. Unfortunately rectal infection with chlamydia and gonorrhea is asymptomatic in the majority of cases of men having sex with men and in high-risk females. A careful history and physical examination is essential in establishing a correct diagnosis, usually supported by proctoscopy, culture, PCR, serology and histology. Certain organisms, more commonly thought of as food- or water-borne disease may be sexually transmitted by direct or indirect fecal-oral contact from various sexual practices.

Prevalence of STI symptoms and high levels of stigma in STI healthcare among men who have sex with men in Dar es Salaam, Tanzania: a respondent-driven sampling study.

Symptoms of sexually transmitted infections (STIs), whether they are presented for treatment or diagnosis, and how they are received by the clinician where they are presented, may be concomitants of stigma associated with homosexuality in homophobic climates. We analyzed respondent-driven sampling data from a study on 200 young men who have sex with men (MSM) in Dar es Salaam, Tanzania to examine sample prevalence, treatment and clinician response to 10 symptoms potentially associated with STIs. Survey measures included 10 self-reported STI symptoms, further specified according to location (genital, anal, oral), further specified according to place of diagnosis, place of, treatment whether there was pharmacy treatment or self-medication, healthcare worker (HCW) inquiries about source of infection and whether the HCW was polite. Most common symptoms reported were genital pain, burning urination, genital itching/burning, penile discharge, and groin swelling. Anal symptoms had the lowest proportion of treatment at public clinics and among the highest proportion of pharmacy treatment; anal sores had the highest proportion of self-medication. HCWs were reported as not being polite in response to 71-90% of the symptoms, (median = 82%). The findings suggest that stigma and negative HCW response are barriers to public clinic treatment for MSM in Tanzania and that these may have implications for both STI treatment and the HIV cascade.

Paroxysmal anal hyperkinesis: a characteristic feature of proctalgia fugax.

Rao, S S; Hatfield, R A

1996-10-01

Proctalgia fugax is a common problem, yet its pathophysiology is poorly understood. The objective was to characterise colorectal disturbances in a paraplegic patient with a 10 year history of proctalgia fugax that began two years after an attack of transverse myelitis. Standard anorectal manometry and prolonged 33 hour ambulatory colonic manometry at six sites in the colon were performed together with myoelectrical recording of the anus. Provocative tests designed to simulate psychological and physical stress and two types of meals were included. Anorectal manometry showed normal internal sphincter tone and normal rectoanal inhibitory reflex but an inability to squeeze or to bear down or to expel a simulated stool. Rectal sensation (up to 360 ml inflation) was absent. Pudendal nerve latency was prolonged (4.5 ms (normal < 2.2 ms). During colonic manometry, the patient reported 27 episodes of pain, of which 23 (85%) were associated with bursts (1-60 min) of a high amplitude (0.5 to > 3.2 mv), high frequency (5-50/min) anal myoelectrical activity, particularly after stress tests, meals, and at night. The myoelectrical disturbance only occurred with proctalgia. Intermittently, 16 bursts of 3 cycles/ min phasic rectal contractions were seen, but only six were associated with proctalgia. Colonic motility was reduced compared with normal subjects. The temporal association between a high amplitude, high frequency myoelectrical activity of the anal sphincter, and the occurrence of proctalgia suggests that paroxysmal hyperkinesis of the anus may cause proctalgia fugax.

Parikartika resembles fissure-in-ano which is very common among all ano-rectal disorders. In Ayurvedic texts, Parikartika is described as a complication of Vamana and Virechana as well as complication of Atisara. Ksharasutra was proved successful in the management of fistula-in-ano, piles, and there is a need to try its efficacy in fissure-in-ano. To evaluate the role of Ksharasutra suturing (KSS) in fissure bed in chronic fissure-in-ano. Total 100 patients of chronic fissure-in-ano were selected and randomly divided into two groups (50 in each group). In group-A, patients were undergone by KSS; while in patients of Group-B Lord's anal dilatation followed by KSS was done under spinal anesthesia. The KSS was done once and after slough out of Ksharasutra, the wound was treated for 4 weeks and assessment of the result was done on the basis of gradation adopted. The pain relief on 14(th) day in Group-A was 86% while in Group-B 100% was observed. As on 7(th) day in Group-A, oozing was stopped in 68% patients, while in Group-B, oozing was stopped in 82% patients. On 21(st) day, Group-B showed more healing (85%) as compared to Group-A (69%). In this study 68% of patients were cured. In Group-B (KSS with Lord's anal dilatation) patients were cured early as compared to patients of Group-A (KSS alone).

In the Dark: Young Men’s Stories of Sexual Initiation in the Absence of Relevant Sexual Health Information

A growing body of research is investigating the effectiveness of abstinence only sexual education. There remains a dearth of research on the relevant sexual health information available to young men who have sex with men (YMSM). Drawing on a mixed-methods study with 526 YMSM, this study explores how and where YMSM receive relevant information on sexual health/behavior. Findings indicate that information related to gay men’s sexuality is not readily available from family, friends or schools. At initiation of anal intercourse, respondents generally had limited information about HIV and STIs. In some cases, this resulted in the perception that activities such as unprotected sex were “low risk”. Many mentioned they first learned about anal sex during their sexual debut, describing painful and/or unpleasant experiences. Some relied on older/more experienced partners, the internet and pornography for information. Findings are discussed in relation to how providers can help YMSM build solid foundations of sexual education to protect them from STI and HIV infection. PMID:19574587

Lateral internal sphincterotomy for surgically recurrent chronic anal fissure.

PubMed

Liang, Jennifer; Church, James M

2015-10-01

Lateral internal sphincterotomy cures chronic anal fissure by preventing internal sphincter hypertonia. However, cutting sphincter predisposes to sphincter dysfunction, manifests as incontinence of gas, liquid, or stool. Surgeons, therefore, can be too cautious in its use, making ineffective superficial incisions or avoiding the operation altogether. This study is designed to confirm the role of redo lateral internal sphincterotomy in the treatment of surgically recurrent chronic anal fissure. Patients undergoing repeat lateral internal sphincterotomy for surgically recurrent chronic anal fissure were accessed from a prospectively maintained database. Chronicity was defined by symptoms persisting more than 3 weeks. Contralateral sphincterotomy was performed with electrocautery through a stab incision over the intersphincteric plane. The length of sphincter division was the same as the length of the fissure. Phone questionnaire was administered and fecal continence was assessed by modified Cleveland Clinic Incontinence Score. Patients were asked to rank their overall satisfaction with the operation, and pre- and postoperative quality of life. There were 57 patients, 24 women and 33 men; mean age was 47.9 ± 14.8 years. Mean follow-up was 12.5 ± 4.2 years (range 6.2 to 25.2 years). Presenting symptoms included pain (100%), bleeding (80%), pruritus ani (39%), constipation (26%), and diarrhea. Fifty patients (90%) presented with 1 fissure, and 40 were posterior. Most procedures were performed on an outpatient basis. Fissure healing rate was 98%, and 2 patients (4%) developed minor incontinence postoperatively (one of gas, the other, gas and seepage). Overall satisfaction was 9.7 ± .9 out of 10 with a significant improvement in the quality of life from 5.7 ± 2.4 out of 10 to 9.3 ± 1.4 out of 10 (P < .001). Judicious repeat lateral sphincterotomy cures recurrent chronic fissures with minimal risk of incontinence. Copyright © 2015 Elsevier Inc. All rights reserved.

Establishment of model of visceral pain due to colorectal distension and its behavioral assessment in rats

PubMed Central

Yang, Jian-Ping; Yao, Ming; Jiang, Xing-Hong; Wang, Li-Na

2006-01-01

AIM: To establish a visceral pain model via colorectal distension (CRD) and to evaluate the efficiency of behavioral responses of CRD by measuring the score of abdominal withdrawal reflex (AWR) in rats. METHODS: Thirty-eight male SD rats weighing 180-240g were used to establish the visceral pain model. The rat was inserted intra-anally with a 7 cm long flexible latex balloon under ether anesthesia, and colorectal distensions by inflating the balloon with air were made 30 min after recovering from the anesthesia. Five AWR scores (AWR0 to AWR4) were used to assess the intensity of noxious visceral stimuli. It was regarded as the threshold of the minimal pressure (kPa) for abdominal flatting was induced by colorectal distension. RESULTS: A vigorous AWR to distension of the descending colon and rectum was found in 100% of the awake rats tested. The higher the pressure of distension, the higher the score of AWR. The distension pressures of 0, 2.00, 3.33, 5.33 and 8.00 kPa produced different AWR scores (P < 0.05). The pain threshold of AWR was constant for up to 80 min after the initial windup (first 1-3 distensions), the mean threshold was 3.69 ± 0.35 kPa. Systemic administration of morphine sulfate elevated the threshold of visceral pain in a dose-dependent and naloxone reversible manner. CONCLUSION: Scoring the AWR during colorectal distensions can assess the intensity of noxious visceral stimulus. Flatting of abdomen (AWR 3) to CRD as the visceral pain threshold is clear, constant and reliable. This pain model and its behavioral assessment are good for research on visceral pain and analgesics.

Hemorrhoidal disease is the first cause of proctological consultation although epidemiology is poorly documented. Pathophysiology is complex and involves a fragmentation of supporting tissues as well as vascular changes with hypervascularization and/or impaired venous return. The only complication of external hemorrhoids is thrombosis, which is responsible for acute anal pain irrespective of bowel movements. Internal hemorrhoids most frequently cause prolapse and/or bleeding which is easily recognizable. Physical examination always confirms the diagnosis and a colonoscopy is required after 40 or 45 in order to rule out colorectal cancer. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Multiple clinical presentations of anal ultra slow waves and high anal pressure: megacolon, hemorrhoids and constipation.

The physiopathology of idiopathic chronic constipation is complex and yet to be investigated. In the manometric studies of the patients with severe chronic constipation, we noticed that some patients with megacolon show very slow periodical (< 2/min) pressure change in the anal canal, namely ultra slow waves (USWs). USWs are considered to represent the hyperactivity of the internal anal sphincter; however, USW-related clinical presentations have yet to be investigated. We retrospectively re-evaluated the patient records and manometric studies of 85 cases, 51 subjects without defecatory problems and 34 patients with constipation, to elucidate USW-related clinical presentations. USWs were seen in 10 patients, including eight patients with chronic constipation and two subjects without defecatory problems. Out of the eight patients with constipation, one had no organic change in the anorectum, three had hemorrhoids and four exhibited megacolon. Manometric and pathological studies proved that none of the four patients with megacolon was suffering from Hirschsprung's disease. Among the 51 subjects without defecatory problems, only two had USWs. Anal pressure in the USW-positive group (106.0 +/- 37.0 cmH2O) was significantly higher than that in the group without defecatory problems (56.0 +/- 27.0 cmH2O) or constipated patients without USWs (55.0 +/- 26.0 cmH2O). Megacolon and high anal pressure, as well as chronic constipation and hemorrhoids, were the clinical presentations related to USWs. This is the first report to show the clinical relevance of USWs to megacolon. USWs should be recognized as an important manometric finding indicating a possible new clinical entity in chronic constipation.

Fecal incontinence is an unresolved problem, which has a serious effect on patients, both physically and psychologically. For patients with severe symptoms, treatment with an artificial anal sphincter could be a potential option to restore continence. Currently, the Acticon Neosphincter is the only device certified by the US Food and Drug Administration. In this paper, the clinical safety and efficacy of the Acticon Neosphincter are evaluated and discussed. Furthermore, some other key studies on artificial anal sphincters are presented and summarized. In particular, this paper highlights that the crucial problem in this technology is to maintain long-term biomechanical compatibility between implants and surrounding tissues. Compatibility is affected by changes in both the morphology and mechanical properties of the tissues surrounding the implants. A new approach for enhancing the long-term biomechanical compatibility of implantable artificial sphincters is proposed based on the use of smart materials.

We report on a consanguineous Turkish family whose first son died of anal atresia and whose second son presented with severe pre- and post-natal growth retardation as well as striking microcephaly, immunodeficiency, congenital heart disease, chromosomal instability and rhabdomyosarcoma in the anal region. The proband was found to carry the homozygous 657del5 mutation in the NBS1 gene, which is responsible for Nijmegen breakage syndrome (NBS) in most of the Slav populations. Our family, the first diagnosed with NBS in the Turkish population, represents one of the most severely affected examples of the syndrome, with profound pre- and post-natal growth retardation associated with structural abnormalities, and expands the clinical spectrum of this rare disorder.

Thermal responses of shape memory alloy artificial anal sphincters

Luo, Yun; Takagi, Toshiyuki; Matsuzawa, Kenichi

2003-08-01

This paper presents a numerical investigation of the thermal behavior of an artificial anal sphincter using shape memory alloys (SMAs) proposed by the authors. The SMA artificial anal sphincter has the function of occlusion at body temperature and can be opened with a thermal transformation induced deformation of SMAs to solve the problem of severe fecal incontinence. The investigation of its thermal behavior is of great importance in terms of practical use in living bodies as a prosthesis. In this work, a previously proposed phenomenological model was applied to simulate the thermal responses of SMA plates that had undergone thermally induced transformation. The numerical approach for considering the thermal interaction between the prosthesis and surrounding tissues was discussed based on the classical bio-heat equation. Numerical predictions on both in vitro and in vivo cases were verified by experiments with acceptable agreements. The thermal responses of the SMA artificial anal sphincter were discussed based on the simulation results, with the values of the applied power and the geometric configuration of thermal insulation as parameters. The results obtained in the present work provided a framework for the further design of SMA artificial sphincters to meet demands from the viewpoint of thermal compatibility as prostheses.

Stimulation of the pudendal nerve or the anal sphincter could provide therapeutic options for fecal incontinence with little involvement of other organs. The goal of this project was to assess the effects of pudendal nerve and anal sphincter stimulation on bladder and anal pressures. Ten virgin female Sprague Dawley rats were randomly allocated to control (n = 2), perianal stimulation (n = 4), and pudendal nerve stimulation (n = 4) groups. A monopolar electrode was hooked to the pudendal nerve or placed on the anal sphincter. Aballoon catheter was inserted into the anus to measure anal pressure, and a catheter was inserted into the bladder via the urethra to measure bladder pressure. Bladder and anal pressures were measured with different electrical stimulation parameters and different timing of electrical stimulation relative to spontaneous anal sphincter contractions. Increasing stimulation current had the most dramatic effect on both anal and bladder pressures. An immediate increase in anal pressure was observed when stimulating either the anal sphincter or the pudendal nerve at stimulation values of 1 mA or 2 mA. No increase in anal pressure was observed for lower current values. Bladder pressure increased at high current during anal sphincter stimulation, but not as much as during pudendal nerve stimulation. Increased bladder pressure during anal sphincter stimulation was due to contraction of the abdominal muscles. Electrical stimulation caused an increase in anal pressures with bladder involvement only at high current. These initial results suggest that electrical stimulation can increase anal sphincter pressure, enhancing continence control.

The purpose of this study was to assess the role of transperineal sonography in assessment of pathologic changes to the anal sphincter complex in patients with chronic anal fissures. We conducted a prospective case-control study of 100 consecutive patients of any age and both sexes with chronic anal fissures who presented to a colorectal clinic between January 2012 and August 2013 (group A) and 50 healthy volunteers (group B). The most common patterns of radiologic changes to anal sphincters associated with chronic anal fissures were circumferential thickening of the anal sphincter complex in 5 patients (5%), circumferential thickening of the internal anal sphincter in 3 patients (3%), preferential thickening of the internal anal sphincter at the 6-o'clock position in 80 patients (80%) and the 12-o'clock position in 7 patients (7%), preferential thickening of the internal and external anal sphincters in 3 patients (3%), and thinning of the internal anal sphincter in 2 patients (2%). Chronic anal fissures cause differential thickening of both internal and external anal sphincters, with a trend toward increased thickness in relation to the site of the fissure. Routine preoperative transperineal sonography for patients with chronic anal fissures is recommended, and it is mandatory in high-risk patients. © 2014 by the American Institute of Ultrasound in Medicine.

In Ayurvedic texts, Parikartika is described as a complication of Vamana and Virechana as well as complication of Atisara. Ksharasutra was proved successful in the management of fistula-in-ano, piles, and there is a need to try its efficacy in fissure-in-ano. Aim: To evaluate the role of Ksharasutra suturing (KSS) in fissure bed in chronic fissure-in-ano. Materials and Methods: Total 100 patients of chronic fissure-in-ano were selected and randomly divided into two groups (50 in each group). In group-A, patients were undergone by KSS; while in patients of Group-B Lord's anal dilatation followed by KSS was done under spinal anesthesia. The KSS was done once and after slough out of Ksharasutra, the wound was treated for 4 weeks and assessment of the result was done on the basis of gradation adopted. Results: The pain relief on 14th day in Group-A was 86% while in Group-B 100% was observed. As on 7th day in Group-A, oozing was stopped in 68% patients, while in Group-B, oozing was stopped in 82% patients. On 21st day, Group-B showed more healing (85%) as compared to Group-A (69%). In this study 68% of patients were cured. Conclusion: In Group-B (KSS with Lord's anal dilatation) patients were cured early as compared to patients of Group-A (KSS alone). PMID:25558158

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. 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. 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. Anorectal pressures and rectal sensation can be conveniently measured by portable manometry and are significantly correlated with high-resolution manometry. © 2015 John Wiley & Sons Ltd.

The incidence of anal cancer has increased in the past decade, especially among men who have sex with men (MSM) and HIV-infected individuals. There is controversy about whether to routinely screen for anal cancer in MSM. To determine whether current anal cancer screening behaviors, intention, and concern differ by HIV serostatus and to identify characteristics of men who intend to seek anal cancer screening. Cross-sectional analysis of data collected from 901 HIV-infected and 1,016 HIV-uninfected MSM from the Multicenter AIDS Cohort Study (MACS) in 2005-2006. Self-reported anal cancer screening history, attitudes, and intentions. A history of anal warts was relatively common in these men (39%), whereas having a recent anal Pap test (5%), intention to seek anal cancer screening in the next 6 months (12%), and concern about anal cancer (8.5%) were less common. Intention to seek anal cancer screening was associated with enabling factors (screening availability, health insurance), need factors (HIV-infection, history of anal warts), concern about anal cancer, and recent sexual risk taking. Among four large US cities, there was significant regional variability in anal cancer screening behaviors, intention, and concern (all p<0.001). Most MSM (76%) indicated they would go to their primary care physician for an anal health problem or question. This study demonstrates a low rate of anal cancer screening and intention to screen among MSM. As more evidence emerges regarding screening, primary care physicians should be prepared to discuss anal cancer screening with their patients.

Objective To investigate the long-term impact of anal sphincter laceration on anal incontinence. Study Design Five to ten years after first delivery, anal incontinence and other bowel symptoms were measured using the Epidemiology of Prolapse and Incontinence Questionnaire and the short form of the Colorectal-Anal Impact Questionnaire. Obstetrical exposures were assessed with review of hospital records. Symptoms and quality of life impact were compared between 90 women with at least one anal sphincter laceration, 320 who delivered vaginally without sphincter laceration and 527 who delivered by cesarean. Results Women who sustained an anal sphincter laceration were most likely to report anal incontinence (odds ratio 2.32; 95% confidence interval 1.27, 4.26) and reported the greatest negative impact on quality of life. Anal incontinence and quality of life scores were similar between women who delivered by cesarean and those who delivered vaginally without sphincter laceration. Conclusion(s) Anal sphincter laceration is associated with anal incontinence 5-10 years after delivery. PMID:22831810

Pavetta indica Linn. (Family: Rubiaceae; Sanskrit name: Papata) is 2-5 m tall, shrub or small tree with opposite branches and grows in the Asia - Pacific region including Sri Lanka. Purishaja Krimi is one of the worm infestations described in Ayurveda. Enterobius vermicularis is among the most common of worms affecting children and adults. E. vermicularis is considered as one type of Purishaja Krimi. Sri Lankan traditional and ayurvedic physicians use P. indica to treat different ailments including Purishaja Krimi (E. vermicularis) infestations successfully. Since no scientific studies have been undertaken to study these effects so far, the present clinical study was carried out to evaluate the effect of P. indica in treatment of E. vermicularis infestation. Fifty patients between age of 5 and 12 years (Group A and B) and 50 patients between 13 and 65 years (Group C and D) with symptoms of E. vermicularis infestations such as itching in the anal region, impaired appetite, abdominal pain, eructation, diarrhea or constipation and presence of ova in stools were selected. Two decoction of the trail drug with different concentration was prepared. Group A and Group B were treated with 60 ml of decoction 1 and 60 ml of placebo respectively, twice daily for 14 days. Group C and Group D were treated with 120 ml of decoction 2 and 120 ml of placebo respectively, twice daily for 14 days. Groups A and C showed complete or partial reduction of symptoms, that is; itching in the anal region, impaired appetite, abdominal pain, eructation, diarrhea and also ova of E. vermicularis were absent in stools after treatment with P. indica. Decoction of P. indica can be recommended as an effective treatment for Purishaja Krimi (E. vermicularis infestation).

To characterise the influence of diet on abdominal symptoms, anal gas evacuation, intestinal gas distribution and colonic microbiota in patients complaining of flatulence. Patients complaining of flatulence (n=30) and healthy subjects (n=20) were instructed to follow their usual diet for 3 days (basal phase) and to consume a high-flatulogenic diet for another 3 days (challenge phase). During basal phase, patients recorded more abdominal symptoms than healthy subjects in daily questionnaires (5.8±0.3 vs 0.4±0.2 mean discomfort/pain score, respectively; p=<0.0001) and more gas evacuations by an event marker (21.9±2.8 vs 7.4±1.0 daytime evacuations, respectively; p=0.0001), without differences in the volume of gas evacuated after a standard meal (262±22 and 265±25 mL, respectively). On flatulogenic diet, both groups recorded more abdominal symptoms (7.9±0.3 and 2.8±0.4 discomfort/pain, respectively), number of gas evacuations (44.4±5.3 and 21.7±2.9 daytime evacuations, respectively) and had more gas production (656±52 and 673±78 mL, respectively; p<0.05 vs basal diet for all). When challenged with flatulogenic diet, patients' microbiota developed instability in composition, exhibiting variations in the main phyla and reduction of microbial diversity, whereas healthy subjects' microbiota were stable. Taxa from Bacteroides fragilis or Bilophila wadsworthia correlated with number of gas evacuations or volume of gas evacuated, respectively. Patients complaining of flatulence have a poor tolerance of intestinal gas, which is associated with instability of the microbial ecosystem.

Women with an obstetric anal sphincter injury are concerned about the risk of recurrent obstetric anal sphincter injury in their second pregnancy. Existing studies have failed to clarify whether the recurrence of obstetric anal sphincter injury affects the risk of anal and fecal incontinence at long-term follow-up. The objective of the study was to evaluate whether recurrent obstetric anal sphincter injury influenced the risk of anal and fecal incontinence more than 5 years after the second vaginal delivery. We performed a secondary analysis of data from a postal questionnaire study in women with obstetric anal sphincter injury in the first delivery and 1 subsequent vaginal delivery. The questionnaire was sent to all Danish women who fulfilled inclusion criteria and had 2 vaginal deliveries 1997-2005. We performed uni- and multivariable analyses to assess how recurrent obstetric anal sphincter injury affects the risk of anal incontinence. In 1490 women with a second vaginal delivery after a first delivery with obstetric anal sphincter injury, 106 had a recurrent obstetric anal sphincter injury. Of these, 50.0% (n = 53) reported anal incontinence compared with 37.9% (n = 525) of women without recurrent obstetric anal sphincter injury. Fecal incontinence was present in 23.6% (n = 25) of women with recurrent obstetric anal sphincter injury and in 13.2% (n = 182) of women without recurrent obstetric anal sphincter injury. After adjustment for third- or fourth-degree obstetric anal sphincter injury in the first delivery, maternal age at answering the questionnaire, birthweight of the first and second child, years since first and second delivery, and whether anal incontinence was present before the second pregnancy, the risk of flatal and fecal incontinence was still increased in patients with recurrent obstetric anal sphincter injury (adjusted odds ratio, 1.68 [95% confidence interval, 1.05-2.70), P = .03, and adjusted odds ratio, 1.98 [95% confidence interval, 1.13-3.47], P = .02, respectively). More women with recurrent obstetric anal sphincter injury reported affected the quality of life because of anal incontinence (34.9%, n = 37) compared with women without recurrent obstetric anal sphincter injury (24.2%, n = 335), although this difference did not reach statistical significance after adjustment (adjusted odds ratio, 1.53 [95% confidence interval, 0.92-2.56] P = .10). Women opting for vaginal delivery after obstetric anal sphincter injury should be informed about the risk of recurrence, which is associated with an increased risk of long-term flatal and fecal incontinence.

Postoperative pain after haemorrhoidectomy: role of impaired evacuation.

PubMed

Puigdollers, A; Cisternas, D; Azpiroz, F

2011-08-01

We hypothesized that obstructive defaecation is associated with more postoperative pain after haemorrhoidectomy. Fifty patients with grade IV haemorrhoids were included in a prospective study. Impaired evacuation was defined as the inability to evacuate a rectal balloon. Perianal sensitivity was evaluated by means of an algometer, and anxiety and depression were assessed by the hospital anxiety and depression (HAD) scale. Over the first 10 days after a Milligan-Morgan haemorrhoidectomy, the following parameters were measured on daily questionnaires: pain (associated with and unrelated to defaecation by means of visual analogue scales), number of bowel movements, faecal consistency and analgesic requirement on demand (tramadol 50 mg p.o., number of doses). Results are expressed as median and interquartile range or mean ± SE. Patients with impaired evacuation (14 women, eight men; age range 28-61 years) experienced more postoperative pain than patients with nonimpaired evacuation (eight women, 20 men; age range 24-70 years): 3.2 (2.1) vs 2.1 (1.8) defaecatory pain, respectively (P = 0.045), and 2.4 (2.3) vs 1.7 (2.3) nondefecatory pain, respectively (P = 0.048). There was no difference between the groups regarding stool consistency, number of bowel movements [12.5 (7.3) vs 15.5 (7.2), respectively; NS] and analgesic requirement [1.0 (6.1) vs 1.0 (5.2) extra doses on demand, respectively; NS] during the 10 postoperative days. No differences related to age, sex, HAD scores or perianal sensitivity were found. Impaired anal evacuation is predictive of postoperative pain after haemorrhoidectomy. © 2011 The Authors.

Anal cancer is caused by human papillomavirus (HPV), yet little is known about anal HPV infection among healthy young women. A total of 2017 sexually active women in the control arm of an HPV-16/18 vaccine trial had a single anal specimen collected by a clinician at the 4-year study visit. Samples were tested for HPV by SPF(10) PCR/DEIA/LiPA(25), version 1. A total of 4% of women had HPV-16, 22% had oncogenic HPV, and 31% had any HPV detected in an anal specimen. The prevalence of anal HPV was higher among women who reported anal intercourse, compared with those who did not (43.4% vs 28.4%; P< .001). Among women who reported anal intercourse, cervical HPV (adjusted odds ratio [aOR], 5.3 [95% confidence interval {CI}, 3.4-8.2]), number of sex partners (aOR, 2.2 [95% CI, 1.1-4.6] for ≥ 4 partners), and number of anal intercourse partners (aOR, 1.9 [95% CI, 1.1-3.3] for ≥ 2 partners) were independent risk factors for anal HPV detection. Among women who reported no anal intercourse, cervical HPV (aOR, 4.7 [95% CI, 3.7-5.9]), number of sex partners (aOR, 2.4 [95% CI, 1.7-3.4] for ≥ 4 partners), and report of anal fissures (aOR, 2.3 [95% CI, 1.1-4.8]) were associated with an increased odds of anal HPV detection. Anal HPV is common among young women, even those who report no anal sex, and was associated with cervical HPV infection. Anal fissures in women who report never having had anal intercourse may facilitate HPV exposure. NCT00128661.

Persistent high-risk human papillomavirus (HR-HPV) infection is associated with the development of anogenital cancers, particularly in men living with HIV (MLWH). We describe the prevalence of anogenital HPV infection, abnormal anal cytology and anogenital warts (AGWs) in MLWH in Johannesburg, and explore whether HPV infection and receipt of antiretroviral treatment is associated with detection of abnormal anal cytology and AGWs. We enrolled a cohort of 304 sexually-active MLWH ≥18 years, who completed a questionnaire and physical examination. Genital swabs were collected from all men and intra-anal swabs from 250 (82%). Swabs were tested for HPV DNA and genotypes, and anal smears graded using the Bethesda classification. Factors associated with anogenital disease were assessed by logistic regression models. Two thirds were receiving antiretroviral treatment, for a median 33 months (IQR = 15-58) and 54% were HIV-virologically suppressed. Only 5% reported ever having sex with men. Among 283 genital swabs with valid results, 79% had any HPV, 52% had HR-HPV and 27% had >1 HR-HPV infection. By comparison, 39% of the 227 valid intra-anal swabs had detectable HPV, 25% had any HR-HPV and 7% >1 HR infection. While most anal smears were normal (51%), 20% had ASCUS and 29% were LSIL. No cases had HSIL or cancer. Infection with >1 HR type (adjusted OR [aOR] = 2.39; 95%CI = 1.02-5.58) and alpha-9 types (aOR = 3.98; 95%CI = 1.42-11.16) were associated with having abnormal cytology. Prevalence of AGWs was 12%. Infection with any LR type (aOR = 41.28; 95%CI = 13.57-125.62), >1 LR type (aOR = 4.14; 95%CI = 1.60-10.69), being <6 months on antiretroviral treatment (aOR = 6.90; 95%CI = 1.63-29.20) and having a CD4+ count <200 cells/μL (aOR = 5.48; 95%CI: 1.60-18.78) were associated with having AGWs. In this population, anogenital HR-HPV infection and associated low-grade disease is common, but severe anal dysplasia was not detected. Findings reinforce the need for HPV vaccination in men for preventing both AGWs and HR-HPV infection. Given the absence of anal HSILs, however, the findings do not support the use of anal screening programmes in this population.

Risk of recurrence, subsequent mode of birth and morbidity for women who experienced severe perineal trauma in a first birth in New South Wales between 2000 –2008: a population based data linkage study

PubMed Central

2013-01-01

Background Severe perineal trauma occurs in 0.5-10% of vaginal births and can result in significant morbidity including pain, dyspareunia and faecal incontinence. The aim of this study is to determine the risk of recurrence, subsequent mode of birth and morbidity for women who experienced severe perineal trauma during their first birth in New South Wales (NSW) between 2000 – 2008. Method All singleton births recorded in the NSW Midwives Data Collection between 2000–2008 (n=510,006) linked to Admitted Patient Data were analysed. Determination of morbidity was based upon readmission to hospital within a 12 month time period following birth for a surgical procedure falling within four categories: 1. Vaginal repair, 2. Fistula repair, 3. Faecal and urinary incontinence repair, and 4. Rectal/anal repair. Women who experienced severe perineal trauma during their first birth were compared to women who did not. Results 2,784 (1.6%) primiparous women experienced severe perineal trauma during this period. Primiparous women experiencing severe perineal trauma were less likely to have a subsequent birth (56% vs 53%) compared to those not who did not (OR 0.9; CI 0.81-0.99), however there was no difference in the subsequent rate of elective caesarean section (OR 1.2; 0.95-1.54), vaginal birth (including instrumental birth) (OR 1.0; CI 0.81-1.17) or normal vaginal birth (excluding instrumental birth) (OR 1.0; CI 0.85-1.17). Women were no more likely to have a severe perineal tear in the second birth if they experienced this in the first (OR 0.9; CI 0.67-1.34). Women who had a severe perineal tear in their first birth were significantly more likely to have an ‘associated surgical procedure’ within the ≤12 months following birth (vaginal repair following primary repair, rectal/anal repair following primary repair, fistula repair and urinary/faecal incontinence repair) (OR 7.6; CI 6.21-9.22). Women who gave birth in a private hospital compared to a public hospital were more likely to have an ‘associated surgical procedure’ in the 12 months following the birth (OR 1.8; CI 1.54-1.97), regardless of parity, birth type and perineal status. Conclusion Primiparous women who experience severe perineal trauma are less likely to have a subsequent baby, more likely to have a related surgical procedure in the 12 months following the birth and no more likely to have an operative birth or another severe perineal tear in a subsequent birth. Women giving birth in a private hospital are more likely to have an associated surgical procedure in the 12 months following birth. PMID:23565655

Purpose: To examine the distribution of and factors associated with event-level heterosexual anal sex and of event-level condom use during anal sex among adolescent women Methods: Adolescent women (N=387; 14 to 17 years at enrollment) were recruited from primary care clinics for a longitudinal cohort study of STIs and sexual behavior. Data were taken from daily sexual diaries; generalized estimating equation logistic regression assessed the likelihood of anal sex or condom use during anal sex on a given day. Results: Heterosexual anal intercourse is a small but non-random event-level component in adolescent women's sexual behavior. About 30% of anal sex events were condom-protected. Mood, partner and situational factors predicted anal sex, but not condom use during anal sex; within-day and recent behavior factors were the strongest influences on both outcomes. Conclusions: Our findings suggest the importance of providers' screening adolescent women patients during office visits about anal sex and about condom use during anal sex, as well as asking questions about the context of these behaviors to appropriately tailor risk reduction counseling.

This study provides national prevalence estimates of US military veterans with severe pain, and compares veterans with nonveterans of similar age and sex. Data used are from the 2010 to 2014 National Health Interview Survey on 67,696 adults who completed the Adult Functioning and Disability Supplement. Participants with severe pain were identified using a validated pain severity coding system imbedded in the National Health Interview Survey Adult Functioning and Disability Supplement. It was estimated that 65.5% of US military veterans reported pain in the previous 3 months, with 9.1% classified as having severe pain. Compared with veterans, fewer nonveterans reported any pain (56.4%) or severe pain (6.4%). Whereas veterans aged 18 to 39 years had significantly higher prevalence rates for severe pain (7.8%) than did similar-aged nonveterans (3.2%), veterans age 70 years or older were less likely to report severe pain (7.1%) than nonveterans (9.6%). Male veterans (9.0%) were more likely to report severe pain than male nonveterans (4.7%); however, no statistically significant difference was seen between the 2 female groups. The prevalence of severe pain was significantly higher in veterans with back pain (21.6%), jaw pain (37.5%), severe headaches or migraine (26.4%), and neck pain (27.7%) than in nonveterans with these conditions (respectively: 16.7%, 22.9%, 15.9%, and 21.4%). Although veterans (43.6%) were more likely than nonveterans (31.5%) to have joint pain, no difference was seen in the prevalence of severe pain associated with this condition. Prevalence of severe pain, defined as that which occurs "most days" or "every day" and bothers the individual "a lot," is strikingly more common in veterans than in members of the general population, particularly in veterans who served during recent conflicts. Additional assistance may be necessary to help veterans cope with their pain. Published by Elsevier Inc.

Objective The aim of this study was to systematically review the findings of publications addressing the epidemiology of anal HPV infection, anal intraepithelial neoplasia and anal cancer in women. Data Sources We conducted a systematic review among publications published from January 1, 1997 to September 30, 2013 in order to limit to publications from the combined antiretroviral therapy (cART) era. Three searches were performed of the National Library of Medicine PubMed database using the following search terms: “women and anal HPV”, “women anal intraepithelial neoplasia”, and “women and anal cancer.” Study Eligibility Criteria Publications were included in the review if they addressed any of the following outcomes: (1) prevalence, incidence, or clearance of anal HPV infection, (2) prevalence of anal cytological or histological neoplastic abnormalities, or (3) incidence or risk of anal cancer. Thirty-seven publications addressing anal HPV infection and anal cytology remained after applying selection criteria, and 23 anal cancer publications met the selection criteria. Results Among HIV-positive women, prevalence of HR-HPV in the anus was 16-85%. Among HIV-negative women, prevalence of anal HR-HPV infection ranged from 4 - 86%. The prevalence of anal HR- HPV in HIV-negative women with HPV-related pathology of the vulva, vagina and cervix compared with women with no known HPV-related pathology, varied from 23-86%, and 5-22%, respectively. Histologic anal HSIL (AIN 2+) was found in 3-26% of the women living with HIV, 0-9% among women with lower genital tract pathology, and 0-3% for women who are HIV-negative without known lower genital tract pathology. The incidence of anal cancer among HIV-infected women ranged from 3.9-30 per 100,000. Among women with a history of cervical cancer or CIN 3, the IR of anal cancer ranged from 0.8-63.8/100,000 person-years, and in the general population, the IRs ranged from 0.55-2.4/100,000 person-years. Conclusions This review provides evidence that anal HPV infection and dysplasia are common in women, especially in those who are HIV-positive or have a history of HPV-related lower genital tract pathology. The incidence of anal cancer continues to grow in all women, especially those living with HIV, despite the widespread use of cART. PMID:25797230

The objectives of the study were to analyze the association between Parkinson's disease and restless legs syndrome, and to explore the relationship between mood disorder comorbidity (anxiety and depression), pain, and restless legs syndrome. This study included 123 Parkinson's disease patients and 123 non-Parkinson's disease patients matched for age and gender, and evaluated for anxiety severity, depression severity, pain severity, pain interference, pain disability, and restless legs syndrome prevalence. This was performed using semi-structured interviews and a neurological examination through the restless legs syndrome diagnostic criteria and the following inventories; Hospital Anxiety and Depression Scale, Brief Pain Inventory, and Pain Disability Index. Parkinson's disease patients had significantly greater anxiety severity, depression severity, pain severity, pain interference, pain disability, and restless legs syndrome prevalence in comparison to controls. In addition, Parkinson's disease patients' comorbid for anxiety and depression had significantly greater pain severity, pain interference, and pain disability, but not RLS prevalence, in comparison to Parkinson's disease only, Parkinson's disease anxiety, and Parkinson's disease depression patients. Pain interference, pain severity, and pain disability is greater among Parkinson's disease patients with anxiety and depression, in comparison to Parkinson's disease patients without anxiety and depression. On the contrary, the prevalence of restless legs syndrome was not found to be relevant.

Lessons from the first dorsal fin in atheriniforms—A new mode of dorsal fin development and its phylogenetic implications

PubMed Central

Richter, Philipp

2017-01-01

Abstract The median fins in extant actinopterygians are the product of millions of years of evolution. During this time, different developmental patterns for the dorsal and anal fins emerged leading to a high variation in median fin morphology and ontogeny. In this study, the development of anal and dorsal fins in atheriniforms is described and its consequences for the current phylogenetic hypothesis are discussed. Developmental series of five atheriniform species were investigated using clearing and staining as well as antibody staining. The skeletal elements of the second dorsal fin and the anal fin emerge in a bidirectional pattern. The first dorsal fin, however, arises separately in front of the second dorsal fin after this one is almost completely formed. The pterygiophores of the first dorsal fin, including the interdorsal pterygiophores, develop from caudal to rostral, but the fin‐spines of the first dorsal fin form in the opposite direction. This new mode of fin development has been found in all examined atheriniform species with two dorsal fins. Several morphological characters of atheriniforms, including interdorsal pterygiophores, are also found in one other taxon: the Mugiliformes. Thus, several dorsal fin characteristics may provide evidence for a closer relationship of these two taxa. PMID:28370120

The severity of pain is routinely assessed in hospitalised patients but the impact of pain and pain control on energy coverage has been poorly studied. This One-day cross-sectional observational study assessed the association between severity of pain and coverage of energy needs in hospitalised patients. Foods provided and consumed were assessed on one day by dedicated dieticians for unselected hospitalised patients receiving three meals per day. Severity of pain was evaluated by a visual analogue scale at the mealtimes, averaged over the study day, and categorized as no pain, slight, moderate or severe pain. The coverage of energy needs was expressed in percentage of predicted needs. Among the 755 included patients, 63% reported having pain. Severe pain was associated with a lower energy coverage than no pain (p = 0.001) or slight pain (p = 0.001). Insufficient energy coverage, defined as ≤70% of predicted needs, occurred in 13% of the patients. In univariate logistic regressions, predictors of insufficient energy coverage were severe pain as compared to no pain (OR 2.38; 95% CI 1.21, 4.64) and treatment with opioid drugs as compared to no pain killer (OR 1.73; 95% CI 1.07, 2.79). When including sex, age, body mass index, treatment with analgesics and severity of pain in a multivariate logistic regression, severe pain more than doubled the risk of insufficient energy coverage (OR 2.32; CI 1.15, 4.66). Patients experiencing severe pain have a high risk of insufficient energy coverage. Optimal pain control is probably critical to prevent underfeeding in the hospital.

Hypersexual, Sexually Compulsive, or Just Highly Sexually Active? Investigating Three Distinct Groups of Gay and Bisexual Men and Their Profiles of HIV-Related Sexual Risk

PubMed Central

Rendina, H. Jonathon; Ventuneac, Ana; Moody, Raymond L.; Grov, Christian

2015-01-01

Emerging research supports the notion that sexual compulsivity (SC) and hypersexual disorder (HD) among gay and bisexual men (GBM) might be conceptualized as comprising three groups—Neither SC nor HD; SC only, and Both SC and HD—that capture distinct levels of severity across the SC/HD continuum. We examined data from 370 highly sexually active GBM to assess how the three groups compare across a range of risk factors for HIV infection. Comparisons focused on psychosexual measures—temptation for condomless anal sex (CAS), self-efficacy for avoiding CAS, sexual excitation and inhibition—as well as reports of actual sexual behavior. Nearly half (48.9 %) of this highly sexually active sample was classified as Neither SC nor HD, 30 % as SC Only, and 21.1 % as Both SC and HD. While we found no significant differences between the three groups on reported number of male partners, anal sex acts, or anal sex acts with serodiscordant partners, the Both SC and HD group reported higher numbers of CAS acts and CAS acts with serodiscordant partners and also had a higher proportion of their anal sex acts without condoms compared to the SC Only group. Our findings support the validity of a three-group classification system of SC/HD severity in differentiating psychosexual and HIV-related sexual risk behavior outcomes in a sample of GBM who report similarly high levels of sexual activity. Notwithstanding the need for sex positive HIV prevention programs, interventions that attempt to help Both SC and HD men deal with distress and address their psychosexual needs specifically may derive HIV prevention benefits.

2013-01-01

Background & Aims Some women with urge-predominant fecal incontinence (FI) have diarrhea-predominant irritable bowel syndrome and a stiffer and hypersensitive rectum. We evaluated the effects of the α2-adrenergic agonist clonidine on symptoms and anorectal functions in women with FI in prospective, placebo-controlled trial. Methods We assessed bowel symptoms and anorectal functions (anal pressures, rectal compliance, and sensation) in 43 women (58±2 y old) with urge-predominant FI randomly assigned to groups given oral clonidine (0.1 mg, twice daily) or placebo for 4 weeks. Before and after administration of the test article, anal pressures were evaluated by manometry, and rectal compliance and sensation were measured using a barostat. Anal sphincter injury was evaluated by endoanal magnetic resonance imaging. Bowel symptoms were recorded in daily and weekly diaries. The primary endpoint was the FI and Constipation Assessment symptom severity score. Results FI scores decreased from 9.1±0.3 to 7.6±0.5 among subjects given placebo and from 8.1±0.4 to 6.5±0.6 among patients given clonidine. Clonidine did not affect FI symptom severity, bowel symptoms (stool consistency or frequency), anal pressures, rectal compliance, or sensation, compared to placebo. However, when baseline data were used to categorize subjects as those with or without diarrhea, clonidine reduced the proportion of loose stools in patients with diarrhea only (P=.018). Clonidine also reduced the proportion of days with FI in patients with diarrhea (P=.0825). Conclusions Overall, clonidine did not affect bowel symptoms, fecal continence, or anorectal functions, compared with placebo, in women with urge-predominant FI. Among patients with diarrhea, clonidine increased stool consistency, with a borderline significant improvement in fecal continence. PMID:23891925

The purpose of this study was to describe the anal lesions found in children during a pediatric gastroenterology consultation when the reason for the complaint was related to a digestive disease. This prospective descriptive study included 100 children under 15 years of age over a 13-month period, consulting due to digestive symptoms. The children were under 8 years old (90%) and 25% were under 3.1 years old. Constipation was the most frequent reason for consultation (69%). Fifty-one anal lesions were observed, of which 58.8% were anal fissures, 15.7% were skin tags and 5.8% were venous congestions related to straining. Anal fissures and skin tags were located at the median line, according to the clock-face method in supine position. No child had more than two anal lesions. No anal dilatation, sphincter hypotonia, anal scars, anal lacerations or bruises were found. The two most common anal lesions were anal fissures and skin tags. These anal lesions were mainly observed at the median line and were due to constipation. No cases of multiple anal lesions were found in terms of common digestive diseases.

Human papilloma virus (HPV) load has been linked to cellular abnormalities of the uterine cervix, and proposed as predictors of HPV persistence and progression of dysplasia to cervical cancer. However, the association of HPV viral load and anal dysplasia and cancer has not been as thoroughly investigated. To examine the association of the viral loads of high-risk HPV types 16, 18, and 52, with the cytologic severity grading in anal-swab specimens of MSM with and without HIV-1 co-infection. A cross-sectional study recruited 200 MSM in northern Thailand from July 2012 to January 2013. Real-time qPCR amplified portion of the HPV E6E7 gene, as well as the human β-globin gene to validate adequacy of the anal specimens and to normalize interpatient viral-load comparisons. Genotyping by linear-array assay identified and distinguished types 16, 18, and 52. HPV-16, and -18 viral loads increased with respect to the abnormality of the cytologic diagnoses (p<0.05 for HPV-16, p<0.01 for HPV-18). HIV-1 positivity was associated with higher HPV-18 viral load (p=0.006). HPV-16 viral loads ≥10 2.24 copies per 5000 anal cells, and HPV-18 loads ≥10 3.15 , were independently associated with abnormal cytology on logistic regression (p=0.022, p=0.041, respectively). Positive predictive values were 85.2% (23/27) and 80.0% (44/55) for the high viral load of a particular HPV-16 and the combined HPV-16, -18 and -52 types, respectively. High viral loads of HPV types 16 and 18 appear to be associated with anal cytologic abnormalities. The clinical utility of HPV viral loads to predict risk for anal cancer remains to be determined by a larger prospective cohort with sufficient frequency of high-grade dysplasia.

We present a case report of an 18-year-old male who was referred to the emergency department with evidence of methaemoglobinaemia. He presented with classic symptoms with peripheral cyanosis and hypoxia. Arterial blood gas showed a methaemoglobin level of 36%. This was caused by ingestion of alkyl nitrate, a widespread party drug called "poppers". When inhaled it causes euphoria, reduced pain and relaxation of the anal sphincter, but oral use may induce life-threatening methaemoglobinaemia. The treatment of choice is the antidote methylene blue. After treatment the patient regained full recovery and was discharged on the following day. We discuss classic symptoms, diagnosis and treatment of intoxication with methylene blue.

2012-01-01

Background. Anal cancer is caused by human papillomavirus (HPV), yet little is known about anal HPV infection among healthy young women. Methods. A total of 2017 sexually active women in the control arm of an HPV-16/18 vaccine trial had a single anal specimen collected by a clinician at the 4-year study visit. Samples were tested for HPV by SPF10 PCR/DEIA/LiPA25, version 1. Results. A total of 4% of women had HPV-16, 22% had oncogenic HPV, and 31% had any HPV detected in an anal specimen. The prevalence of anal HPV was higher among women who reported anal intercourse, compared with those who did not (43.4% vs 28.4%; P < .001). Among women who reported anal intercourse, cervical HPV (adjusted odds ratio [aOR], 5.3 [95% confidence interval {CI}, 3.4–8.2]), number of sex partners (aOR, 2.2 [95% CI, 1.1–4.6] for ≥4 partners), and number of anal intercourse partners (aOR, 1.9 [95% CI, 1.1–3.3] for ≥2 partners) were independent risk factors for anal HPV detection. Among women who reported no anal intercourse, cervical HPV (aOR, 4.7 [95% CI, 3.7–5.9]), number of sex partners (aOR, 2.4 [95% CI, 1.7–3.4] for ≥4 partners), and report of anal fissures (aOR, 2.3 [95% CI, 1.1–4.8]) were associated with an increased odds of anal HPV detection. Conclusion. Anal HPV is common among young women, even those who report no anal sex, and was associated with cervical HPV infection. Anal fissures in women who report never having had anal intercourse may facilitate HPV exposure. Clinical Trials Registration. NCT00128661. PMID:22850119

Squamous cell carcinoma of the anus-an opportunistic cancer in HIV-positive male homosexuals

Squamous cell carcinoma of the anus (SCCA) is a common cancer in the human immunodeficiency virus (HIV)-infected population, and its incidence continues to increase in male homosexuals. Combined chemoradiation with mitomycin C and 5-fluorouracil was poorly tolerated by severely immunocompromised patients in the early 1990s. In the era of highly active antiretroviral therapy (HAART), however, recent data indicate that: (1) most HIV patients with anal cancer can tolerate standard chemotherapy regimens; and (2) this approach is associated with survival rates similar to those of HIV-negative patients. However, HIV-positive patients with SCCA are much younger, more likely to develop local tumor recurrence, and ultimately die from anal cancer than immune competent patients. Taken together, these findings suggest that anal cancer is an often fatal neoplasia in middle-aged HIV-positive male homosexuals. In this population, SCCA is an opportunistic disease resulting in patients with suboptimal immune function from persistent infection and prolonged exposition to oncogenic human papillomaviruses (HPVs). Large-scale cancer-prevention strategies (routine anuscopy and anal papanicolaou testing) should be implemented in this population. In addition, definitive eradication of oncogenic HPVs within the anogenital mucosa of high-risk individuals might require a proactive approach with repeated vaccination. PMID:21799644

Molecular biology of anal squamous cell carcinoma: implications for future research and clinical intervention.

2015-12-01

Anal squamous cell carcinoma is a human papillomavirus-related disease, in which no substantial advances in treatment have been made in over 40 years, especially for those patients who develop disease relapse and for whom no surgical options exist. HPV can evade the immune system and its role in disease progression can be exploited in novel immunotherapy platforms. Although several studies have investigated the expression and inactivation (through loss of heterozygosity) of tumour suppressor genes in the pathways to cancer, no clinically valuable biomarkers have emerged. Regulators of apoptosis, including survivin, and agents targeting the PI3K/AKT pathway, offer opportunities for targeted therapy, although robust data are scarce. Additionally, antibody therapy targeting EGFR may prove effective, although its safety profile in combination with standard chemoradiotherapy has proven to be suboptimal. Finally, progress in the treatment of anal cancer has remained stagnant due to a lack of preclinical models, including cell lines and mouse models. In this Review, we discuss the molecular biology of anal squamous cell carcinoma, clinical trials in progress, and implications for novel therapeutic targets. Future work should focus on preclinical models to provide a resource for investigation of new molecular pathways and for testing novel targets. Copyright © 2015 Elsevier Ltd. All rights reserved.

Biodanza is a useful therapy for the fibromyalgia management; however, there is no evidence of its effectiveness on acute pain. The objectives of the present study were: to determine the changes of a 3-month Biodanza program on acute pain severity (before vs. after session) and cumulative pain severity in women with fibromyalgia; and to check the associations of acute pain severity reduction with presession pain severity, body fat percentage, and satisfaction with the session. This was a 3-month low-moderate intensity (rate of perceived exertion around 12, based on a 6-20 point scale) Biodanza intervention study (1 session/week). Twenty-seven women with fibromyalgia (54.2 ± 6.2 years) participated. Pain severity was assessed before and after each single session with a visual analog scale. There were immediate changes in all sessions (p = .001-.028), except in the first, second, and fourth sessions. An overall 16% decrease of acute pain severity before and after each session was noted (mean presession pain vs. postsession pain, 5.8 ± 2.1 vs. 4.9 ± 2.4; respectively). There was an independent association of pain severity reduction (presession-postsession) with presession pain severity (unstandardized coefficient B = .21 ± .05; standardized coefficient β = .25; p < .001), body fat percentage (B = -.05 ± .02; β = -.18; p = .003), and satisfaction with the session (B = .40 ± .15; β = .16; p = .007). There was a significant cumulative effect decrease in postsession pain severity (p < .001; 95% confidence interval [CI] = -.14, -.05) and presession-postsession pain severity (p = .007; 95% CI = .02, .12) along the 3-month intervention. No significant cumulative effect in presession pain severity was identified (p > .05). In conclusion, Biodanza is an alternative therapy that reduced acute pain severity in women with fibromyalgia. The intervention also yielded cumulative pain severity reduction, which were higher in those women with fibromyalgia presenting higher presession pain severity and lower body fat percentage. The satisfaction with the session was also a key factor positively associated with pain reduction. Copyright © 2017 American Society for Pain Management Nursing. Published by Elsevier Inc.

Peikert, Kevin; Platzek, Ivan; Bessède, Thomas; May, Christian Albrecht

2015-04-01

The bulbospongiosus muscle is part of the superficial muscular layer of the perineum and pelvic floor. Its morphology remains controversial in the literature. Therefore, we reinvestigated the fascial arrangement and fiber courses of the bulbospongiosus muscle and its topographical relation to the external anal sphincter. The perineum was dissected in 9 male cadavers (mean ± SD age 78.3 ± 10.7 years). Select samples were obtained for histology and immunohistochemistry. In 43 patients (mean age 60.7 ± 12 years) the topographical relation between the bulbospongiosus muscle and the external anal sphincter was determined by magnetic resonance imaging. The perineum contains several fascial layers consisting of elastic and collagen fibers as well as bundles of smooth muscle cells. The bulbospongiosus muscle was subdivided into a ventral and dorsal portion, which developed in 4 variants. The ventral insertion formed a morphological unity with the ischiocavernous muscle while the dorsal origin had a variable relation to the external anal sphincter (5 variants). A muscle-like or connective tissue-like connection was frequently present between the muscles. However, in some cases the muscles were completely separated. We suggest a concept of variations of bulbospongiosus muscle morphology that unifies the conflicting literature. Its ventral fiber group and the ischiocavernosus muscle form a functional and morphological unity. While the bulbospongiosus muscle and the external anal sphincter remain independent muscles, their frequent connection might have clinical implications for perineal surgery and anogenital disorders.

2018-05-13

Epidemiological studies of chronic pain frequently report high prevalence estimates. However, there is little information about the development and natural course of chronic pain. We followed a random sample of participants from a population-based study (HUNT 3) with annual measures over four years. Among those without chronic pain at baseline, the probability of developing moderate to severe chronic pain (cumulative incidence) during the first year was 5%, a pain status that was maintained among 38% at the second follow-up. The probability of developing chronic pain diminished substantially for those who maintained a status of no chronic pain over several years. Subjects with moderate to severe chronic pain at baseline had an 8% probability of recovery into no chronic pain, a status that was maintained for 52% on the second follow-up. The probability of recovery diminished substantially as a status of chronic pain was prolonged for several years. Pain severity, widespread pain, pain catastrophizing, depression and sleep were significant predictors of future moderate to severe chronic pain, both among subjects with and without chronic pain at baseline. These findings suggest that the prognosis is fairly good after a new onset of chronic pain. When the pain has lasted for several years, the prognosis becomes poor. The same social and psychological factors predict new onset and the prognosis of chronic pain. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Abstract Introduction: Individuals with osteoarthritis (OA) show increased morbidity and mortality. Telomere length, a measure of cellular aging, predicts increased morbidity and mortality. Telomeres shorten with persisting biological and psychosocial stress. Living with chronic OA pain is stressful. Previous research exploring telomere length in people with OA has produced inconsistent results. Considering pain severity may clarify the relationship between OA and telomeres. Objectives: We hypothesized that individuals with high OA chronic pain severity would have shorter telomeres than those with no or low chronic pain severity. Methods: One hundred thirty-six adults, ages 45 to 85 years old, with and without symptomatic knee OA were included in the analysis. Peripheral blood leukocyte telomere length was measured, and demographic, clinical, and functional data were collected. Participants were categorized into 5 pain severity groups based on an additive index of frequency, intensity, time or duration, and total number of pain sites (FITT). Covariates included age, sex, race or ethnicity, study site, and knee pain status. Results: The no or low chronic pain severity group had significantly longer telomeres compared with the high pain severity group, P = 0.025. A significant chronic pain severity dose response emerged for telomere length, P = 0.034. The FITT chronic pain severity index was highly correlated with the clinical and functional OA pain measures. However, individual clinical and functional measures were not associated with telomere length. Conclusion: Results demonstrate accelerated cellular aging with high knee OA chronic pain severity and provide evidence for the potential utility of the FITT chronic pain severity index in capturing the biological burden of chronic pain.

2009-09-01

Rubber band ligation (RBL) is a well-known and recognised outpatient procedure utilised for the treatment of symptomatic internal haemorrhoids. This paper describes a retrospective study which analyses the short- and long-term results of a personal series of patients. A consecutive group of 206 patients with symptomatic internal second- and third-degree haemorrhoids were treated with RBL as outpatients from 1982 to 1989. Two or three piles were legated in a single session. All patients were systematically visited after 1 month and 1 year. Respectively after 10 and 17 years, all the patients were contacted to obtain a telephone follow-up. The short-term follow-up at 1 month and at 1 year showed that 46% of the patients experienced moderate anal pain for 24 h post procedure. Two patients had severe pain (1%) and were admitted in the hospital to be submitted to an operative haemorrhoidectomy within a few days. Only 2.4% of the patients experienced rectal bleeding after a week, and 20% had a second session of RBL after 1 month. At 1 year follow-up, 90% of the patients with second-degree piles and 75% of patients with third-degree piles reported no residual symptoms. The long-term telephone follow-up at 10 and 17 years collected the history of 138 patients (67%). A group of 69% was asymptomatic, 28% had residual symptoms, and 3% needed further surgery. RBL is a safe and effective treatment for symptomatic internal haemorrhoids. Our long-term follow-up demonstrated good long-term results for internal second- and third-degree haemorrhoids.

A case of severe anal injury in an adolescent male due to bestial sexual experimentation.

PubMed

Blevins, Roger O

2009-10-01

This report delineates a case of anal injury in a 12-year-old boy who gave a detailed history of bestial behavior with a male bulldog. The child described how he had seen this behavior modeled on the internet and subsequently initiated contact with his own dog, causing the dog to penetrate him anally. This type of juvenile bestial behavior with injury has only been reported once previously in the medical literature. Zoophilia, along with a number of other paraphilias, frequently has its onset in the adolescent age group. Adolescents evidencing paraphilic behaviors require thorough psychological evaluation. Spontaneous sexual assault of a human by a canine has never been described in the human or veterinary medical literature, nor is such a thing likely. A clinician involved in evaluating serious ano-genital injury in a child reportedly due to spontaneous canine sexual assault must consider other possible traumatic etiologies including sexual abuse. Investigation in any such case is essential. 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Results of Parks operation for faecal incontinence after anal sphincter injury.

PubMed Central

Browning, G G; Motson, R W

1983-01-01

Parks operation for faecal incontinence was performed on 97 patients with total loss of anorectal control due to injury. All had sustained complete division of the anal sphincters as a result of trauma, anal surgery, or obstetric tears and either were incontinent or had been given a colostomy. In all patients the divided sphincters were repaired using an overlapping technique; in 93 the repair was protected by a temporary defunctioning stoma. There was no operative mortality. Continence was completely restored in 65 (78%) and improved in a further 11 (13%) of the 83 patients assessed from four to 116 months postoperatively. Minor complications which did not affect the eventual clinical outcome occurred in 23 patients. Factors associated with failure of the operation included breakdown of the repair in the early postoperative period, fistula, and pelvic floor neuropathy. The results show that even after severe injury to the sphincters surgical reconstruction can restore continence in most patients. Images FIG 1 FIG 2 FIG 3 PMID:6407612

HPV associated bowenoid papulosis of the anogenital region are classified as carcinoma in situ. The treatment can be difficult and recurrence rates are high. Extended surgical resections may have complications such as anal sphincter insufficiency. PDT does have some advantages and less side effects in the treatment of these tumors. We treated one female patient with an extended perianal bowenoid papulosis. Previous surgical resection led to local recurrence and partial sphincter insufficiency. Twenty-four hours before local laser light radiation (Ar-Dye laser, 630 nm wavelength), a systemic photosensitizer was applied (Photofrin II, 1.5 mg/kg BW). Four courses of PDT were performed within one year. We observed a total tumor necrosis in every radiation area. The previous sphincter insufficiency improved during the sessions. Side effects were rare. Pain in the radiation was stopped within 2 - 3 days under pain medication. PDT can induce a total local tumor necrosis in perianal bowenoid papulosis. Concerning local expansion, PDT can be a curable treatment.

A girl of preschool age fell off a trampoline in a sitting position onto an iron bar sticking up from the ground. In addition to a laceration of the terminal portion of the rectum, she was found to have a severe sphincter injury. The sphincters were repaired by a surgeon the next morning. After one month from the surgery the anal canal pressure was found to be symmetrical with good contractile force of the sphincters. No abnormalities were found in a contrast study or in rectoscopy. The protective stoma was closed after three months from the injury and fecal continence was normal after one and a half years.

Objectives To assess incidence of, and risk factors for abnormal anal cytology and anal intraepithelial neoplasia (AIN) 2–3 in HIV-infected women. Study Design This prospective study assessed 100 HIV-infected women with anal and cervical specimens for cytology and high risk HPV testing over three semi-annual visits. Results Thirty-three women were diagnosed with an anal cytologic abnormality at least once. Anal cytology abnormality was associated with current CD4 count <200 cells/mm3, anal HPV infection and history of other sexually transmitted infections (STIs). Twelve subjects were diagnosed with AIN2-3: four after AIN1 diagnosis and four after ≥1 negative anal cytology. AIN2-3 trended towards an association with history of cervical cytologic abnormality and history of STI. Conclusions Repeated annual anal cytology screening for HIV-infected women, particularly for those with increased immunosuppression, anal and/or cervical HPV, history of other STIs, or abnormal cervical cytology, will increase the likelihood of detecting AIN2-3.

A 12-year-old male neutered Siamese cat presented with a history of inappetance and lethargy and an enlarged left anal sac. The anal sac was surgically excised and histopathology confirmed the diagnosis of anal sac adenocarcinoma. Perianal tumours are rare in the cat and anal sac adenocarcinoma has not been previously reported. This is in contrast to the dog where anal sac adenocarcinoma is a well recognised albeit uncommon tumour.

To better understand the cellular origins and differentiation of anal canal epithelial neoplasms, the immunohistochemical profiles of the anal canal epithelium in humans and swine were evaluated. Formalin-fixed tissue sections were immunostained for mucin (MUC: MUC2, MUC5AC, MUC5B), desmoglein 3 (DGS3), p63, CDX2, SOX2, and α-smooth muscle actin (α-SMA). The anal transitional zone (ATZ) epithelium covered the anal sinus and consisted of a stratified epithelium with mucous cells interspersed within the surface lining. Anal glands opened into the anal sinus. Ducts and acini of intraepithelial or periepithelial mucous type were the main structures of human anal glands, whereas those of swine were compound tubuloacinar mixed glands. Distal to the ATZ epithelium, non-keratinized stratified squamous epithelium merged with the keratinized stratified squamous epithelium of the perianal skin. MUC5AC expression predominated over MUC5B expression in the ATZ epithelium, while MUC5B expression was higher in the anal glands. SOX2 was positive in the ATZ epithelium, anal glands, and squamous epithelium except in the perianal skin. In humans, DGS3 was expressed in the ATZ epithelium, anal gland ducts, and squamous epithelium. p63 was detected in the ATZ epithelium, anal glands, and squamous epithelium. Myoepithelial cells positive for α-SMA and p63 were present in the anal glands of swine. Colorectal columnar cells were MUC5B + /MUC2 + /CDX2 + /MUC5AC - /SOX2 - . The ATZ epithelium seems to be a distinctive epithelium, with morphological and functional features allowing smooth defecation. The MUC5AC + /SOX2 + /MUC2 - /CDX2 - profile of the ATZ epithelium and anal glands is a useful feature for diagnosing adenocarcinoma arising from these regions.

Objective Examining the degree to which disease severity and domains of self-efficacy (pain, function, other symptoms) explain pain and functioning in rheumatoid arthritis patients. Methods Patients (N=263) completed the Arthritis Impact Measurements Scales-2 to assess pain and functioning (physical, affective, and social), the Arthritis Self-Efficacy Scale to assess three self-efficacy domains (pain, physical function, other); disease severity was assessed with C-reactive protein, physician's rating, abnormal joint count. Structural equation modeling was used to examine hypotheses: 1) does disease severity have a direct relationship with pain and each area of functioning, 2) does disease severity have a direct relationship with each arthritis self-efficacy domain, and 3) do the self-efficacy domains mediate the relationship between disease severity and RA pain and each area of functioning. Results Disease severity was related to pain, physical functioning, and each self-efficacy domain (β's=.28-.56; p's<.001). Each self-efficacy domain was related to its respective domain of functioning (e.g., self-efficacy for pain was related to pain) (β's=.36-.54; p's<.001). Self-efficacy mediated the relationship between disease severity and pain and functioning (β's=.12-.19; p's<.001). Self-efficacy for pain control and to perform functional tasks accounted for 32-42% of disease severity's total effect on their respective outcomes (e.g., self-efficacy for pain control accounted for 32% of disease severity's total effect on pain). Variance accounted for by the total model was 52% for pain, 53% for physical functioning, and 44% for affective and social functioning. Conclusions Disease severity and self-efficacy both impact RA functioning and intervening in these areas may lead to better outcomes. PMID:20535796

People with chronic pain and comorbid posttraumatic stress disorder (PTSD) report more severe pain and poorer quality of life than those with chronic pain alone. This study evaluated the extent to which associations between PTSD and chronic pain interference and severity are mediated by pain-related coping strategies and depressive symptoms. Veterans with chronic pain were divided into two groups, those with (n=65) and those without (n=136) concurrent PTSD. All participants completed measures of pain severity, interference, emotional functioning, and coping strategies. Those with current PTSD reported significantly greater pain severity and pain interference, had more symptoms of depression, and were more likely to meet diagnostic criteria for a current alcohol or substance use disorder (all p-values ≤ 0.01). Participants with PTSD reported more use of several coping strategies, including guarding, resting, relaxation, exercise/stretching, and coping self-statements. Illness-focused pain coping (i.e., guarding, resting, and asking for assistance) and depressive symptoms jointly mediated the relationship between PTSD and both pain interference (total indirect effect = 0.194, p < 0.001) and pain severity (total indirect effect = 0.153, p = 0.004). Illness-focused pain coping also evidenced specific mediating effects, independent of depression. In summary, specific pain coping strategies and depressive symptoms partially mediated the relationship between PTSD and both pain interference and severity. Future research should examine whether changes in types of coping strategies following targeted treatments predict improvements in pain-related function for chronic pain patients with concurrent PTSD.

The epidemiology of anal incontinence and symptom severity scoring

PubMed Central

Nevler, Avinoam

2014-01-01

For many patients, anal incontinence (AI) is a devastating condition that can lead to social isolation and loss of independence, contributing to a substantial economic health burden, not only for the individual but also for the allocation of healthcare resources. Its prevalence is underestimated because of poor patient reporting, with many unrecorded but symptomatic cases residing in nursing homes. Endosonography has improved our understanding of the incidence of post-obstetric sphincter tears that are potentially suitable for repair and those cases resulting from anorectal surgery, most notably after fistula and hemorrhoid operations. The clinical scoring systems assessing the severity of AI are discussed in this review, along with their limitations. Improvements in the standardization of these scales will advance our understanding of treatment response in an era where the therapeutic options have multiplied and will permit a better comparison between specific therapies.

Anal sex practices in heterosexual and male homosexual populations: a review of population-based data.

PubMed

Heywood, Wendy; Smith, Anthony M A

2012-12-01

Anal sex is known to be an important risk factor for anal cancer. Yet compared with vaginal intercourse, little is known about anal sex practices in either heterosexual or male homosexual populations. Of the data that are available, it appears a significant and increasing minority of heterosexuals have ever practised anal intercourse. Among homosexual men, most, but not all, report anal sex, with large proportions of men engaging in both insertive and receptive anal intercourse. The most significant finding of the review was the dearth of population-based data, particularly relating to homosexual men.

Anal sac gland carcinoma arising from the apocrine secretory epithelium in the anal sac wall, is locally invasive and highly metastatic. The majority of anal sac gland carcinomas are unilateral on presentation, but bilateral tumours have been identified. This case series presents the outcome of four unique cases of unilateral anal sac gland carcinoma which subsequently developed contralateral anal sac gland carcinoma 50 to 390 days after removal of the initial tumour. Median survival was 1035 days after initial diagnosis and 807 days after diagnosis of the second anal sac gland carcinoma. © 2013 British Small Animal Veterinary Association.

Conceptualizations of heterosexual anal sex and HIV risk in five East African communities.

PubMed

Duby, Zoe; Colvin, Christopher

2014-01-01

Heterosexual anal sex is underresearched and little understood, particularly in the African context. Existing prevalence data indicate that heterosexual anal sex is a widespread practice, yet little is known about the way in which it is conceptualized and understood. Describing findings from qualitative research conducted in Kenya, Tanzania, and Uganda, we shed light on conceptualizations of heterosexual anal sex and its relation to human immunodeficiency virus (HIV). These findings suggest that penile-anal sex is practiced by men and women in Africa for a range of reasons, including virginity maintenance, contraception, fulfillment of male pleasure, relationship security, menstruation, in the presence of vaginal complications, financial gain, fidelity, and prestige. Despite anal sex being the most efficient way to transmit HIV sexually, there is widespread lack of knowledge about its risks. These findings describe the ways in which anal sex is conceptualized in five East African communities, highlighting how penile-anal intercourse is often not considered "sex" and how the omission of anal sex in safe-sex messaging is interpreted as meaning that anal sex is safe. In light of its frequency and risks, greater attention must be paid to heterosexual anal sex in Africa to ensure a comprehensive approach to HIV prevention.

Treatment of hemorrhoids: A coloproctologist's view.

PubMed

Lohsiriwat, Varut

2015-08-21

Hemorrhoids is recognized as one of the most common medical conditions in general population. It is clinically characterized by painless rectal bleeding during defecation with or without prolapsing anal tissue. Generally, hemorrhoids can be divided into two types: internal hemorrhoid and external hemorrhoid. External hemorrhoid usually requires no specific treatment unless it becomes acutely thrombosed or causes patients discomfort. Meanwhile, low-graded internal hemorrhoids can be effectively treated with medication and non-operative measures (such as rubber band ligation and injection sclerotherapy). Surgery is indicated for high-graded internal hemorrhoids, or when non-operative approaches have failed, or complications have occurred. Although excisional hemorrhoidectomy remains the mainstay operation for advanced hemorrhoids and complicated hemorrhoids, several minimally invasive operations (including Ligasure hemorrhoidectomy, doppler-guided hemorrhoidal artery ligation and stapled hemorrhoidopexy) have been introduced into surgical practices in order to avoid post-hemorrhiodectomy pain. This article deals with some fundamental knowledge and current treatment of hemorrhoids in a view of a coloproctologist - which includes the management of hemorrhoids in complicated situations such as hemorrhoids in pregnancy, hemorrhoids in immunocompromised patients, hemorrhoids in patients with cirrhosis or portal hypertension, hemorrhoids in patients having antithrombotic agents, and acutely thrombosed or strangulated hemorrhoids. Future perspectives in the treatment of hemorrhoids are also discussed.

Sacral neuromodulations for female lower urinary tract, pelvic floor, and bowel disorders.

Wehbe, Salim A; Whitmore, Kristene; Ho, Mat H

2010-10-01

In recent years, sacral neuromodulation (SNM) has been investigated for the treatment of various types of lower urinary tract and bowel dysfunctions. This review discusses recently published data related to the therapeutic applications of SNM in female lower urinary tract, pelvic floor, and bowel disorders. SNM has been employed initially in the treatment of refractory idiopathic overactive bladder, urge urinary incontinence, and chronic nonobstructive urinary retention. Since then, several studies, including randomized and controlled trials, have confirmed the therapeutic effects of SNM in these disorders. The applications of SNM are now extended to the treatment of other female pelvic problems, such as fecal incontinence, chronic constipation, interstitial cystitis/painful bladder syndrome, sexual dysfunction, and neurogenic disorders, with similar promising results. SNM is approved by the Food and Drug Administration for the treatment of idiopathic overactive bladder, urge urinary incontinence, and chronic nonobstructive urinary retention. SNM is not yet an approved method for the treatment of other pelvic disorders, but data supporting its benefit are emerging. The major advantage of SNM lies in its potential to treat the bladder, urethral sphincter, anal sphincters, and pelvic floor muscles simultaneously, which might result in better therapeutic effects.

Little is known about the magnitude of the risk of anal and rectal cancer in patients with anal and/or perineal Crohn's disease. We aimed to assess the risk of anal and rectal cancer in patients with Crohn's perianal disease followed up in the Cancers Et Surrisque Associé aux Maladies Inflammatoires Intestinales En France (CESAME) cohort. We collected data from 19,486 patients with inflammatory bowel disease (IBD) enrolled in the observational CESAME study in France, from May 2004 through June 2005; 14.9% of participants had past or current anal and/or perianal Crohn's disease. Subjects were followed up for a median time of 35 months (interquartile range, 29-40 mo). To identify risk factors for anal cancer in the total CESAME population, we performed a case-control study in which participants were matched for age and sex. Among the total IBD population, 8 patients developed anal cancer and 14 patients developed rectal cancer. In the subgroup of 2911 patients with past or current anal and/or perianal Crohn's lesions at cohort entry, 2 developed anal squamous-cell carcinoma, 3 developed perianal fistula-related adenocarcinoma, and 6 developed rectal cancer. The corresponding incidence rates were 0.26 per 1000 patient-years for anal squamous-cell carcinoma, 0.38 per 1000 patient-years for perianal fistula-related adenocarcinoma, and 0.77 per 1000 patient-years for rectal cancer. Among the 16,575 patients with ulcerative colitis or Crohn's disease without anal or perianal lesions, the incidence rate of anal cancer was 0.08 per 1000 patient-years and of rectal cancer was 0.21 per 1000 patient-years. Among factors tested by univariate conditional regression (IBD subtype, disease duration, exposure to immune-suppressive therapy, presence of past or current anal and/or perianal lesions), the presence of past or current anal and/or perianal lesions at cohort entry was the only factor significantly associated with development of anal cancer (odds ratio, 11.2; 95% CI, 1.18-551.51; P = .03). In an analysis of data from the CESAME cohort in France, patients with anal and/or perianal Crohn's disease have a high risk of anal cancer, including perianal fistula-related cancer, and a high risk of rectal cancer.

Pain is common among people living with HIV/AIDS (PLWHA), but little is known about chronic pain in socioeconomically disadvantaged HIV-infected populations with high rates of substance abuse in the post-antiretroviral era. This cross-sectional study describes the occurrence and characteristics of pain in a community-based cohort of 296 indigent PLWHA. Participants completed questionnaires about sociodemographics, substance use, depression and pain. Cut-point analysis was used to generate categories of pain severity. Of the 270 participants who reported pain or the use of a pain medication in the past week, 8.2% had mild pain, 38.1% had moderate pain, and 53.7% had severe pain. Female sex and less education were associated with more severe pain. Depression was more common among participants with severe pain than among those with mild pain. Increasing pain severity was associated with daily pain and with chronic pain. Over half of the participants reported having a prescription for an opioid analgesic. Findings from this study suggest that chronic pain is a significant problem in this high risk, socioeconomically disadvantaged group of patients with HIV disease and high rates of previous or concurrent use of illicit drugs.

The association of anal cancer with human papillomavirus (HPV) infection is well established; however, little is known about the epidemiology of anal HPV in healthy women. We investigated patterns of duration and clearance of anal HPV infection in a cohort of healthy women in Hawaii. Viral and nonviral determinants of anal HPV clearance were examined in a longitudinal cohort study of 431 sexually active women. At baseline and at 4-month intervals, interviews were conducted and cervical and anal cell specimens were obtained for detection of HPV DNA. Of the 431 women, 50% experienced a total of 414 incident anal HPV infections, reported at 1 clinic visits from baseline through a follow-up period of average duration of 1.2 years. Of these infections, 58% cleared during follow-up. The clearance rate for a high-risk anal infection was 9.2 per 100 woman-months (95% confidence interval [CI], 6.9-11.9 per 100 woman-months), with a median duration of 150 days (95% CI, 132-243 days). The slowest clearing high-risk HPV types were HPV-59 (median clearance time, 350 days) and HPV-58 (median clearance time, 252 days). The median clearance times for HPV-16 and HPV-18, the predominant types associated with anal cancer, were 132 days and 212 days, respectively. Nonviral factors that delayed clearance of anal HPV included douching, long-term tobacco smoking, and anal sex. The majority of anal HPV infections resolve in a relatively short time. Although anal HPV is commonly acquired in healthy women, its rapid clearance suggests limited efficacy of HPV testing as an anal cancer screening tool.

Pregnancy- and delivery-related factors affect postpartum anal incontinence. We aimed to explore changes in continence status among primiparas from late pregnancy through the first year postpartum. In this prospective cohort study set in two Norwegian hospitals, 862 healthy primiparas completed questionnaires about the main outcome measure anal incontinence, including flatus incontinence and urgency, at three time points; late pregnancy, 6 and 12 months postpartum. Socioeconomic and delivery-related data were obtained from hospital records. Logistic regression analyses were applied to determine the association between continence status at 12 months postpartum, and continence status in late pregnancy, 6 months postpartum, demographic and delivery-related characteristics. Among the 189 (22%) primiparas reporting anal incontinence in late pregnancy, 34 (18%) had persistent anal incontinence 1 year later. Forty-eight (43%) of the 113 women incontinent at 6 months postpartum experienced persistent anal incontinence at 12 months. Eight percent of previously continent women reported new onset anal incontinence at 6 and 12 months after delivery. Occipitoposterior presentation was the only delivery-related factor increasing the risk of postpartum anal incontinence [odds ratio (OR) 1.8, 95% confidence interval (CI) 1.0-3.4]. Young age increased the risk of anal incontinence at 1 year after delivery, whereas incontinence in late pregnancy increased the risk of anal incontinence persisting through 6 and 12 months postpartum. In most first-time mothers with postpartum anal incontinence, the onset of anal incontinence was before delivery. Except for occipitoposterior presentation, no delivery-related factors increased the risk of postpartum anal incontinence. This may indicate that hormonal, mechanical or neuromuscular changes in pregnancy affect long-term anal incontinence more than vaginal delivery. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Do Intra-anal Bowel Management Devices Reduce Incontinence-Associated Dermatitis and/or Pressure Injuries?

The purpose of this article was to examine the evidence and provide recommendations related to the effectiveness of intra-anal bowel management systems including intra-anal bowel catheters and rectal trumpets in reducing incontinence-associated dermatitis and pressure injuries. Does the use of an intra-anal bowel management system (intra-anal bowel catheter or rectal trumpet) reduce incontinence-associated skin damage and/or hospital-acquired pressure injuries in the acute care adult patient population? A search of the literature was performed by a trained university librarian, which resulted in 133 articles that examined intra-anal bowel management systems (intra-anal bowel catheter and rectal trumpet), incontinence-associated dermatitis, and pressure injuries. A systematic approach was used to review titles, abstracts, and text yielding 6 studies that met inclusion criteria. Strength of the evidence was rated using rating methodology from Essential Evidence Plus: Levels of evidence and Oxford Center for Evidence-based Medicine, adapted by Gray and colleagues. Five of the 6 studies reported positive results concerning the effectiveness of intra-anal bowel management systems to reduce incontinence-associated dermatitis and/or pressure injuries. One randomized control trial found no improvement in incontinence-associated dermatitis in the intra-anal bowel management system (intra-anal bowel catheter or rectal trumpet) groups or pressure injuries as compared to usual care. The strength of the evidence for the identified studies was moderate (2 level A, 3 level B, and 1 level C). An important finding in 2 of the studies was the safety of the intra-anal bowel management systems-both intra-anal bowel catheter and rectal trumpet. Evidence indicates intra-anal bowel management system (intra-anal bowel catheters and rectal trumpet) provides a viable option for fecal incontinence management and these devices reduce incontinence-associated dermatitis and/or pressure injuries.

Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy. Biopsy of both tumors revealed a similar histology of well- to moderately differentiated adenocarcinoma. There was no sign of metastases in lymph nodes or other organs. For the purpose of diagnosis and treatment, transperineal local resection of the anal tumor was performed, and it was histologically identified as adenocarcinoma of squamous cells with no invasion to muscles, lymph ducts, or microvessels. The pathological margin was free. Then, to achieve radical cure, laparoscopic low anterior resection (LAR) with D3 lymphadenectomy was performed. The histological diagnosis of the anal tumor was adenocarcinoma of squamous cells without invasion to muscles, lymph ducts, or vessels. The surgical margin was completely free. Immunohistochemical analysis of both tumors revealed similar staining patterns, and the final diagnosis was rectal cancer with metastasis to the anal skin. The patient received no postoperative therapy, and no recurrences have been observed 12 months after surgery. We expect that our sphincter-preserving surgical strategy provided a good prognosis for the synchronous rectal cancer and anal metastasis. This is a rare report of a case with an anal metastasis of colorectal cancer on perianal squamous cells without a history of anal disease that was resected while preserving anal function.

To study pain prevalence, pain type, and its pharmacological treatment in Dutch nursing home residents in relation to dementia subtype and dementia severity. Data were collected as part of the PAINdemiA study, an observational cross-sectional study conducted between May 2014 and December 2015. Ten nursing homes in the Netherlands. A total of 199 nursing home residents in various stages of dementia. We collected data on pain (by observation: MOBID-2 Pain Scale and by self-report scales), pain type, pain medication, dementia subtype, dementia severity (GDS), and demographic features. In the whole sample, the prevalence of pain was 43% (95% confidence interval 36%-50%) using the MOBID-2 Pain Scale. Regardless of regularly scheduled analgesics, approximately one-third of the residents with pain suffered from moderate to severe pain. Pain assessment with the MOBID-2 Pain Scale showed no difference in pain between dementia subtypes, but residents with more severe dementia experienced pain more often than those with less severe dementia (27% vs 15%). The prevalence of self-reported pain was significantly higher in residents with vascular dementia (VaD) (54%) compared with those with Alzheimer disease (18%) and other dementia subtypes (14%). Nociceptive pain was the predominant type of pain (72%) followed by mixed pain (25%). Acetaminophen was the most prescribed analgesic (80%). Most of the participating nursing home residents had no pain; however, pain was observed more often in residents with severe dementia, whereas residents in the early stages of VaD self-reported pain more often that those with other dementia subtypes. As one-third of the residents with clinically relevant pain had moderate to severe pain regardless of using pain medication, more focus should be on how pain management could use more tailored approaches and be regularly adjusted to individual needs.

Carcinogenic human papillomaviruses (HPVs) cause a large proportion of anal cancers. Human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) are at increased risk of HPV infection and anal cancer compared with HIV-negative men. We evaluated risk factors for HPV infection and anal precancer in a population of HIV-infected MSM. Our study included 305 MSM at an HIV/AIDS clinic in the Kaiser Permanente Northern California Health Maintenance Organization. Logistic regression was used to estimate associations of risk factors comparing men without anal HPV infection; men with anal HPV infection, but no precancer; and men with anal precancer. Low CD4 count (<350 cells/mm(3)) and previous chlamydia infection were associated with an increased risk of carcinogenic HPV infection (odds ratio [OR], 3.65; 95% confidence interval [CI], 1.28-10.40 and OR, 4.24; 95% CI, 1.16-15.51, respectively). History of smoking (OR, 2.71 95% CI, 1.43-5.14), duration, recency, and dose of smoking increased the risk of anal precancer among carcinogenic HPV-positive men but had no association with HPV infection. We found distinct risk factors for anal HPV infection and anal precancer. Risk factors for HPV infection and anal precancer are similar to established risk factors for cervical cancer progression.

Women who had abnormal results on equally or over atypical squamous cells of undetermined significance were classified as having abnormal anal cytology. A multiple logistic regression analysis (stepwise) was performed to identify the risk for developing abnormal anal cytology. Data were analyzed using the SPSS 20.0 program. The average age was 41.09 (±12.64). Of the total participants, 75.5% did not practice anal sex, 91% did not have HPV-infected partners, 92% did not have any anal pathology, and 68.5% did not have anal bleeding. More than half (57.5%) had genital SIL and a significant number developed abnormal anal cytology: 13% in the total sample and 17.4% in women with genital SIL. A significant association was observed between genital squamous intraepithelial lesion and anal squamous intraepithelial lesion (PR=2.46; p=0.03). In the logistic regression model, women having genital intraepithelial lesion were more likely to have abnormal anal Pap smear (aPR=2.81; p=0.02). This report shows that women with genital squamous intraepithelial lesion must be more closely screened for anal cancer. Copyright © 2016 Elsevier Editora Ltda. All rights reserved.

Despite the fact that countless patients suffer from anal problems, there tends to be a lack of understanding of anal health care. Unfortunately, this leads to incorrect diagnoses and treatments. When treating a patient with an anal complaint, the primary goals are to first diagnose the etiology of the symptoms correctly, then to provide an effective and appropriate treatment strategy. The first step in this process is to take an accurate history and physical examination. Specific questions include details about bowel habits, anal hygiene, and fiber supplementation. Specific components of the physical examination include an external anal examination, a digital rectal examination, and anoscopy if appropriate. Common diagnoses include pruritus ani, anal fissures, hemorrhoids, anal abscess or fistula, fecal incontinence, and anal skin tags. However, each problem presents differently and requires a different approach for management. It is of paramount importance that the correct diagnosis is reached. Common errors include an inaccurate diagnosis of hemorrhoids when other pathology is present and subsequent treatment with a steroid product, which is harmful to the anal area. Most of these problems can be avoided by improving bowel habits. Adequate fiber intake with 30 g to 40 g daily is important for many reasons, including improving the quality of stool and preventing colorectal and anal diseases. In this Special Report, we provide an overview of commonly encountered anal problems, their presentation, initial treatment options, and recommendations for referral to specialists. PMID:27723447

Dropped head syndrome (DHS) is defined as weakness of the neck extensor muscles causing a correctable chin-on-the-chest deformity. Here we report the case of a patient with severe pain from lower leg ischemia showing DHS whose symptoms were attenuated by pain relief after amputation of the severely ischemic lower leg. To our knowledge this is the first report indicating that severe pain can cause DHS. A 64-year-old Asian woman was referred to our department with a 1-month history of DHS. She also suffered from severe right foot pain because of limb ischemia. She began to complain of DHS as her gangrenous foot pain worsened. She had neck pain and difficulty with forward gaze. We found no clinical or laboratory findings of neuromuscular disorder or isolated neck extensor myopathy. We amputated her leg below the knee because of progressive foot gangrene. Her severe foot pain resolved after the surgery and her DHS was attenuated. Severe pain can cause DHS. If a patient with DHS has severe pain in another part of the body, we recommend considering aggressive pain relief as a treatment option.

Objective: People living with sickle cell disease (SCD) experience severe episodic and chronic pain and frequently report poor interpersonal treatment within health-care settings. In this particularly relevant context, we examined the relationship between perceived discrimination and both clinical and laboratory pain. Methods: Seventy-one individuals with SCD provided self-reports of experiences with discrimination in health-care settings and clinical pain severity, and completed a psychophysical pain testing battery in the laboratory. Results: Discrimination in health-care settings was correlated with greater clinical pain severity and enhanced sensitivity to multiple laboratory-induced pain measures, as well as stress, depression, and sleep. After controlling for relevant covariates, discrimination remained a significant predictor of mechanical temporal summation (a marker of central pain facilitation), but not clinical pain severity or suprathreshold heat pain response. Furthermore, a significant interaction between experience with discrimination and clinical pain severity was associated with mechanical temporal summation; increased experience with discrimination was associated with an increased correlation between clinical pain severity and temporal summation of pain. Discussion: Perceived discrimination within health-care settings was associated with pain facilitation. These findings suggest that discrimination may be related to increased central sensitization among SCD patients, and more broadly that health-care social environments may interact with pain pathophysiology.

Developing interventions to address racial/ethnic cancer pain disparities requires exploration of the role of socioeconomic status, health status, and pain severity from the time of diagnosis. To examine patterns of disparities in cancer pain by evaluating differences by race/ethnicity in the odds of reporting pain and in pain severity, controlling for key patient-level covariates. This study used data from a nationally representative cohort of colorectal and lung cancer patients. Multivariable logistic regression was conducted to examine the relationship between race/ethnicity and reporting pain. Multivariable linear regression was then conducted, among those who reported pain, to determine differences in pain severity by race/ethnicity. The cohort included 5761 individuals (14% black, 7% Hispanic/Latino, 6% Asian or Pacific Islander, and 3% multiracial), among whom 48% reported pain. The adjusted odds of reporting differed only for multiracial patients, who were more likely to report pain than whites (odds ratio: 1.54; P = 0.036). However, among those with pain, severity was higher for black patients (β = 6.6; P ≤ 0.001) and multiracial patients (β = 4.5; P = 0.036) relative to white patients. Lower educational attainment, depressed affect, and lower levels of wealth also were associated with higher pain severity. Although the odds of experiencing pain differed only for multiracial patients, among those reporting pain, both blacks and multiracial individuals reported higher pain severity than whites. Sociodemographic status, health status, and depression were associated with severity but did not explain the disparity. Interventions to address these disparities will need to focus on reported severity and patient-level factors. Published by Elsevier Inc.

Female sex workers have been disproportionately affected with HIV and anal sexual experience elevate their vulnerability. Anal intercourse has more risk of HIV transmission than vaginal intercourse for receptors that coupled with low condom and proper lubricant use behavior during anal sex. Besides majority of them did not understand HIV transmission risk of anal intercourse. In Ethiopia, studies on anal sexual experience is almost none existent, so the purpose of this study is to explored anal sexual experience and HIV transmission risk awareness among female sex worker in Dire Dawa, Eastern Ethiopia. Qualitative study with thematic analysis approach was conducted among 18 female sex workers and recruitment of study participants performed until saturation of information. The principal investigator conducted in-depth interviews using local language (Amharic) and it was recorded on audio recorder. Tape recorded data was transcribed and translated to English and entered into open code version 3.4 for coding and theme identification. Data collection conducted simultaneously with data analysis. Female sex workers practiced anal sex for different themes like financial influence, coercion, intentionally, peer pressure and as a sign of intimacy and love. Coercion, negative attitudes, poor awareness about HIV transmission risks of anal sex and protection capacity of condom and proper lubricants are the identified themes for not using condom and proper lubricants during anal sex by female sex workers. Inaccessibility and unavailability of health services for issues related to anal sex was the core reason for female sex workers' misperception and risk anal sexual experience. Female sex workers practiced anal sex without risk reduction approaches and they did not understand exacerbated risk of anal sex to HIV transmission. Stakeholders including ministry of health need to incorporate potential awareness raising tasks and programs about risk of anal sex and methods of risk reduction for female sex workers.

The risk of anal cancer due to high-risk human papillomavirus (HR-HPV) is higher in women living with human immunodeficiency virus (HIV) than in the general population. We present findings of cervical and anal HPV and cytologic tests at baseline in the EVVA cohort study and HPV persistence data 6 months after baseline. Semiannual visits included questionnaires, chart reviews, cervical/anal cytologic and cervical/anal HPV testing for 2 years. Genotyping for 36 HPV genotypes was performed using the Roche Linear Array HPV genotyping test. A total of 151 women living with HIV were recruited. At baseline, 75% had anal HPV, 51% had anal HR-HPV, 50% had cervical HPV, and 29% had cervical HR-HPV. Anal HPV-16 and HPV-51 were more frequent in women born in Canada (31% and 29%, respectively, compared with ≤16% for other women). Most anal HR-HPV types detected at 6 months (57%-93%) were persistent from baseline. Findings of anal cytologic tests were abnormal for 37% of women. Anal HPV is highly prevalent in women living with HIV, and type distribution varies by place of birth. High-resolution anoscopy was indicated in more than one third of results. As anal cancer is potentially preventable, these important findings need to be considered when selecting the best approach for anal cancer screening programs. © The Author 2017.

ElNaggar, Adam C; Santoso, Joseph T; Xie, Huiwen Bill

2012-02-01

To identify factors that may contribute to poor sensitivity of anal cytology in contrast to the sensitivity of anoscopy in heterosexual women. We analyzed 324 patients with biopsy confirmed diagnosis of genital intraepithelial neoplasia (either vulva, vaginal, or cervical) from 2006 to 2011 who underwent both anal cytology and anoscopy. Cytology, anoscopy, and biopsy results were recorded. Biopsy specimens underwent independent analysis for quality of specimen. Also, biopsy specimens were analyzed for characteristics that may contribute to correlation, or lack thereof, between anal cytology and anoscopic directed biopsy. 133 (41%) patients had abnormal anoscopy and underwent directed biopsy. 120 patients with normal anal cytology had anoscopy directed biopsies, resulting in 58 cases of AIN (sensitivity 9.4%; 0.039-0.199). This cohort was noted to have extensive keratosis covering the entire dysplastic anal lesion. 18 patients yielded abnormal anal cytology. Of these patients, 13 had anoscopic directed biopsies revealing 6 with AIN and absent keratosis (specificity 88.6%; 0.78-0.95). The κ statistic for anal cytology and anoscopy was -0.0213 (95% CI=-0.128-0.086). Keratosis reduces the sensitivity of anal cytology. Furthermore, anal cytology poorly correlates with anoscopy in the detection of AIN (κ statistic=-0.0213). Copyright © 2011 Elsevier Inc. All rights reserved.

Vaginal birth delivery may result in acute and persistent perineal pain postpartum. This study evaluated the association between catastrophizing, a phenomenon of poor psychological adjustment to pain leading the individual to magnify the painful experience making it more intense, and the incidence and severity of perineal pain and its relationship to perineal trauma. Cohort study conducted with pregnant women in labor. We used the pain catastrophizing scale during hospitalization and assessed the degree of perineal lesion and pain severity in the first 24 hours and after 8 weeks of delivery using a numerical pain scale. We evaluated 55 women, with acute pain reported by 69.1%, moderate/severe pain by 36.3%, and persistent pain by 14.5%. Catastrophizing mean score was 2.15 ± 1.24. Catastrophizing patients showed a 2.90 relative risk (RR) for perineal pain (95% CI: 1.08-7.75) and RR: 1.31 for developing persistent perineal pain (95% CI: 1.05-1.64). They also showed a RR: 2.2 for developing acute and severe perineal pain (95% CI: 1.11-4.33). The incidence of acute and persistent perineal pain after vaginal delivery is high. Catastrophizing pregnant women are at increased risk for developing acute and persistent perineal pain, as well as severe pain. Perineal trauma increased the risk of persistent perineal pain.

The prevalence of cervical and anal human papillomavirus (HPV) and risk factors associated with infections were evaluated in a cross-sectional study of 211 adult women in American Samoa. Overall, 53% of women reported ever having a Pap smear. Cervical and anal HPV was detected in 10% and 16% of women, respectively; 4% of women had concurrent cervical and anal HPV. The most common cervical genotypes were HPV 6, HPV 16, and HPV 53. Cutaneous HPV types were detected in 40% of anal infections. Cervical HPV infection was associated with anal HPV (age-adjusted odds ratio = 3.32, 1.10–10.00). After age adjustment, cervical HPV was associated with being unmarried, postsecondary education, hot running water at home, multiple sexual partners, nulliparity, condom use, and other contraceptive methods. In multivariate analyses, only age remained associated with cervical HPV and anal HPV. Cervical and anal HPV was more prevalent among younger women; only anal HPV was detected in older women.

Anal cancer, although a still rare disease, is being observed in ascending rates among some population segments known to be at risk for the development of the disease. Human papillomavirus (HPV) infection, immunodepression and anal intercourse are some factors associated with the development of the malignancy. Its similarities to cervical cancer have led to many studies aiming to establish guidelines for detecting and treating precursor lesions of anal cancer, with the goal of prevention. High-resolution anoscopy is routinely used for the diagnosis of anal cancer precursor lesions in many centers but the medical literature is still deficient concerning the role of this diagnostic modality. To evaluate diagnostic validation and precision measures of high-resolution anoscopy in comparison to histopathological results of anal biopsies performed in HIV-positive patients treated at the Tropical Medicine Foundation of Amazonas, AM, Brazil. To observe any possible association between some risk factors for the development of anal cancer and the presence of anal squamous intraepithelial lesions. A hundred and twenty-eight HIV-positive patients were submitted to anal canal cytological sampling for the detection of HPV infection by a PCR based method. High-resolution anoscopy was then performed after topical application of acetic acid 3% in the anal canal for 2 minutes. Eventual acetowhite lesions that were detected were recorded in respect to location, and classified by their tinctorial pattern, distribution aspect, relief, surface and vascular pattern. Biopsies of acetowhite lesions were performed under local anesthesia and the specimens sent to histopathological analysis. The patients were interviewed for the presence of anal cancer risk factors. The prevalences of anal HPV infection and of anal squamous intraepithelial lesions in the studied population were, respectively, 79% and 39.1%. High-resolution anoscopy showed sensibility of 90%, specificity of 19.23%, positive predictive value of 41.67%, negative predictive value of 75%, and a kappa coefficient of 0.076. From the analyzed lesions, high-grade squamous intraepithelial lesions was more frequently observed in association to dense (68%), flat (61%), smooth (61%), non-papillary (83%) and normal vascular pattern (70%) acetowhite lesions, while low-grade squamous intraepithelial lesions tended to be associated to dense (66%), flat-raised or raised (68%), granular (59%), non-papillary (62%) and normal vascular pattern (53%) acetowhite lesions. No statistical significance was observed as to the association of epidemiological characteristics and of most of the investigated anal cancer risk factors and presence of acetowhite lesions or anal squamous intraepithelial lesions. However, anal receptive sex and anal HPV infection were significantly associated to anal squamous intraepithelial lesions (P = 0.0493 and P = 0.006, respectively). High-resolution anoscopy demonstrated to be a sensitive, but not specific test for the detection of anal squamous intraepithelial lesions. Risk factors anal receptive sex and anal HPV infection were significantly associated to the presence of anal squamous intraepithelial lesions. Based on high-resolution anoscopy image data, acetowhite lesions relief and surface pattern were prone to distinguish between low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions.

The efficacious and safe use of transurethral injections of polyacrylamide hydrogel (Bulkamid(®)) in women with stress urinary incontinence suggests that it may be suitable also for treatment of anal incontinence. We aimed to determine the effectiveness and safety of polyacrylamide hydrogel when used as a transanal submucosal bulking agent in women with anal incontinence. Thirty women with a diagnosis of anal incontinence and a Cleveland Clinic Incontinence Score (CCIS) >10 were randomized to three different techniques of transanal submucosal injections using polyacrylamide hydrogel. Follow up was performed at 2, 6 and 12 months using CCIS and the Fecal Incontinence Quality of Life scale (FIQL). In all, 29 of the 30 women completed the follow up. Approximately half of the women requested a re-injection at the 6-month visit. The overall CCIS improved significantly from baseline (14.7. SD 2.5) to 1 year (12.4. SD 3.1) (p = 0.003). There was a significant improvement with regard to the occurrence of loose fecal incontinence (p = 0.014) but not for solid fecal incontinence (p = 0.28). At 1 year the FIQL domains of coping-behavior, depression, and embarrassment showed significant improvements (p = 0.012, p = 0.007 and p = 0.007, respectively). We recorded no adverse events related either to the injection technique or the biomaterial. There were no significant differences between the treatment groups in either CCIS or FIQL scores. Transanal submucosal injection of polyacrylamide hydrogel resulted in a modest although significant overall improvement in anal incontinence symptom scores with corresponding improvements in several domains of quality of life, regardless of injection volume. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Obstetric anal sphincter injury is common but the effect on body image is unreported. The aim of this study was to explore patient perceived changes in body image and other psychological aspects in women attending a perineal follow-up clinic. This retrospective study analysed women's responses to a self-reported questionnaire. Consecutive women with anal sphincter injury who attended a United Kingdom Maternity Hospital perineal follow-up clinic between January 1999 and January 2012 were identified and the records obtained and reviewed. Multivariate regression analyses were performed to examine variables influencing self-reported change in body image. Questionnaires and operation notes were analysed from 422 women who attended at a median of four months after delivery. 222 (53%) reported a change in body image with 80 (19%) reporting lower self-esteem and 75 (18%) a change in their personality due to the change in body image. 248 (59%) perceived an anatomical change due to the delivery. Factors associated with increased likelihood of reporting a change in body image were reporting a perceived change in anatomy due to the delivery, adjusted OR 6.11 (3.56-10.49), anal incontinence, OR 1.97 (1.16-3.36), and delivery by forceps, OR 2.59 (1.23-5.43). This is the first study to quantify body image changes in women after anal sphincter injury sustained in childbirth. These were found to be very common, affecting up to 50% of women. The study has several limitations but it does highlight the significant psychosocial problems of negative self-esteem and personality changes associated with a perceived change in body image that has not previously been reported. It also outlines the further research questions that need to be addressed. Copyright © 2017 Elsevier B.V. All rights reserved.

A study is made of the alterations in anorectal physiology among rectal prolapse patients, evaluating the differences between fecal continent and incontinent individuals. Eighteen patients with complete rectal prolapse were divided into two groups: Group A (8 continent individuals) and Group B (10 incontinent women), while 22 healthy women were used as controls (Group C). Clinical exploration and perineal level measurements were performed, along with anorectal manometry, electrophysiology, and anorectal sensitivity to electrical stimuli. The main antecedents of the continent subjects were excess straining efforts, while the incontinent women presented excess straining and complex deliveries. Pathological perineal descent was a frequent finding in both groups, with a hypotonic anal canal at rest (p < 0.001 vs controls) and at voluntary squeezing (p < 0.001 vs controls). In turn, the incontinent patients exhibited a significantly lower anal canal pressure at rest than the continent women (p < 0.05). There were no significant differences between Groups A and C in terms of pudendal motor latency, though latency was significantly longer in Group B than in the controls (p < 0.01). Moreover, pudendal neuropathy was more common, severe and often bilateral in Group B. There were no differences in rectal sensation to distention or in terms of the volumes required to relax the internal anal sphincter. In turn, both prolapse groups exhibited diminished anal canal and rectal sensitivity to electrical stimuli. Patients with rectal prolapse exhibit a hypotonic anal canal at rest, regardless of whether they are continent to feces or not. Continent patients have less pudendal neuropathy and therefore less pressure alterations at voluntary sphincter squeeze than incontinent individuals.

Prayer and pain: the mediating role of positive re-appraisal.

Dezutter, Jessie; Wachholtz, Amy; Corveleyn, Jozef

2011-12-01

The present study explored in a sample of Flemish pain patients the role of prayer as a possible individual factor in pain management. The focus on prayer as a personal religious factor fits with the current religious landscape in Western-Europe where personal religious factors are more important than organizational dimensions of religion. Our study is framed in the transactional theory of stress and coping by testing first, whether prayer was related with pain severity and pain tolerance and second, whether cognitive positive re-appraisal was a mediating mechanism in the association between prayer and pain. We expected that prayer would be related to pain tolerance in reducing the impact of the pain on patient's daily life, but not necessarily to pain severity. A cross-sectional questionnaire design was adopted in order to measure demographics, prayer, pain outcomes (i.e., pain severity and pain tolerance), and cognitive positive re-appraisal. Two hundred and two chronic pain (CP) patients, all members of a Flemish national patients association, completed the questionnaires. Correlational analyses showed that prayer was significantly related with pain tolerance, but not with pain severity. However, ancillary analyses revealed a moderational effect of religious affiliation in the relationship between prayer and pain severity as well as pain tolerance. Furthermore, mediation analysis revealed that cognitive positive re-appraisal was indeed an underlying mechanism in the relationship between prayer and pain tolerance. This study affirms the importance to distinguish between pain severity and pain tolerance, and indicates that prayer can play a role in pain management, especially for religious pain patients. Further, the findings can be framed within the transactional theory of stress and coping as the results indicate that positive re-appraisal might be an important underlying mechanism in the association between prayer and pain.

Background. An increasing incidence of anal cancer among men suggests a need to better understand anal canal human papillomavirus (HPV) infection among human immunodeficiency virus–negative men. Methods. Genotyping for HPV was conducted on cells from the anal canal among men who have sex with women (MSW) and men who have sex with men (MSM), aged 18–70 years, from Brazil, Mexico, and the United States. Factors associated with anal HPV infection were assessed using multivariable logistic regression. Results. The prevalence of any HPV type and oncogenic HPV types did not differ by city. Anal canal HPV prevalence was 12.2% among 1305 MSW and 47.2% among 176 MSM. Among MSW, reporting a lifetime number of ≥10 female sex partners, a primary sexual relationship <1 year in duration, and a prior hepatitis B diagnosis were independently associated with detection of any anal HPV in multivariable analysis. Among MSM, a younger age, reporting ≥2 male anal sex partners in the past 3 months, and never using a condom for anal sex in the past 6 months were independently associated with detection of any anal HPV in multivariable analysis. Conclusions. Number of sex partners was associated with anal HPV infection in both MSW and MSM. Anal HPV infection in men may be mediated by age, duration of sexual relationship, and condom use.

In the United States, anal cancer in men who have sex with men (MSM) is more common than cervical cancer in women. Human papillomavirus (HPV) is causally linked to the development of anal and cervical cancer. In women, cervical HPV infection peaks early and decreases after the age of 30. Little is known about the age-specific prevalence of anal HPV infection in human immunodeficiency virus (HIV)-negative MSM. We studied the prevalence and determinants of anal HPV infection in 1218 HIV-negative MSM, 18-89 years old, who were recruited from 4 US cities. We assessed anal HPV infection status by polymerase chain reaction. HPV DNA was found in the anal canal of 57% of study participants. The prevalence of anal HPV infection did not change with age or geographic location. Anal HPV infection was independently associated with receptive anal intercourse (odds ratio [OR], 2.0; P<.0001) during the preceding 6 months and with >5 sex partners during the preceding 6 months (OR, 1.5; P<.0001). Urban, HIV-negative MSM have a stable, high prevalence of anal HPV infection across all age groups. These results differ substantially from the epidemiologic profile of cervical HPV infection in women. This may reflect differences between these populations with respect to the number of new sex partners after the age of 30 and may explain the high incidence of anal cancer in MSM.

HIV-positive men who have sex with men (MSM) are at increased risk of anal cancer. We evaluate the risk factors for anal high-grade squamous intraepithelial lesion (HSIL) (the precursor of anal cancer) in HIV-positive MSM. In this cross-sectional study within a cohort, 320 HIV-positive MSM were screened by anal cytology followed by high-resolution anoscopy (HRA) in case of abnormal cytology. Risk factors for anal HSIL were analysed. Men were mostly middle-aged Caucasians with median CD4+ T lymphocytes of 638 cells/µL, 87% on combined antiretroviral therapy (cART) for a median of 5 years. 198 anal cytology samples were normal. In the 122 patients with abnormal cytology, HRA with biopsies were performed: 12% (n=15) normal, 36% (n=44) anal low-grade squamous intraepithelial lesion (LSIL) and 51% (n=63) anal HSIL. Comparing patients with or without anal HSIL (normal cytology or normal biopsy or LSIL), we found in multivariate analysis significantly fewer anal HSIL in patients with cART ≥24 months (OR 0.32 CI 95% 0.162 to 0.631, p=0.001). Prolonged cART (≥24 months) is associated with fewer anal HSIL. Published by the BMJ Publishing Group Limited.

Objective: To assess the effectiveness of different modes of treatment of chronic anal fissure as regards improvement of symptoms and complications. Methods: This prospective study included 129 consecutive patients with chronic anal fissures presented to the Surgical Outpatients’ Department of Islam Teaching Hospital Sialkot, Pakistan; from September 2010 to November 2012. Patients were distributed in three groups. In “OBG group”, patients had attended Gynae/Obs OPD and got treated and were then referred to surgical OPD for failure of treatment or recurrence. Patients who presented with history of treatment by GPs were included in “GP Group” “SGR Group” included those who directly reported to surgical OPD for treatment. Patients were managed both pharmacologically as OPD patients and surgically as admitted patients. Patients were instructed to apply small amounts of 0.2% GTN paste in soft white paraffin, to the anoderm with finger tips three times a day. Patients were evaluated at two-week intervals and at each visit the symptoms control, adverse effects and fissure status were recorded. If there was symptomatic relief or the fissure healing was in progress, the treatment was continued for a total duration of eight weeks. Operated patients were nursed in wards after surgery i.e Internal Anal Sphicterotomy. They were advised to report to OPD weekly for one month or earlier if they experienced any symptoms suggestive of complications. Patients were declared cured in case of complete symptomatic relief with fissure healing. Success, failure and associated problems were recorded and analysed to get results. Results:This study included 129 patients who could be followed up for a minimum of three months. These patients were referred by gynaecologist i.e. 22 (17%) for treatment failure while 5 patients with wrong diagnosis were not included in statistical analysis; similarly 41 (32%) patients were referred by general practitioners and 9 patients with wrong diagnosis were excluded. Sixty six patients i.e. 51% were those who directly reported to surgical OPD and had no previous treatment. With surgical treatment, pain, bleeding per rectum and constipation showed significant improvement as compared to GTN ointment application. Fissure healing was 100% in surgical group as compared to 74% in medical group. Complications were recorded and were found to be headache with medical treatment; while the most feared complication with surgical treatment i.e. permanent incontinence was not encountered in our study. Conclusion: Topical glyceryl trinitrate is economical, has a good healing rate, and faecal incontinence has not been reported. Its effectiveness, however, depends on patients’ compliance which may be poor in view of associated headaches and a local burning sensation. It is first line of treatment for anal fissure but lateral internal sphincterotomy is superior, more effective and curative than the chemical sphincterotomy. Surgery is reserved for people with anal fissure who have tried medical therapy for at least one to three months but failed. PMID:24353726

Our aim was to prospectively evaluate pelvic floor retraining (PFR) in improving symptomatic fecal incontinence. PFR was used to treat 30 patients with fecal incontinence (28 women; age range, 29-85 (median, 68) years). PFR was performed by a physiotherapist in the outpatient department according to a strict protocol and included biofeedback using an anal plug electromyometer. Manometry (24 patients), pudendal nerve terminal motor latency (PNTML, 16 patients), and anal ultrasound (14 patients) were done before commencing therapy. Independent assessment of symptoms was done at the commencement of therapy, at 6 weeks, and at 6 and 12 months posttherapy. Twenty patients (67 percent) had improved incontinence scores, with eight patients (27 percent) being completely or nearly free of symptoms. Of 28 patients followed up longer than six months, 14 achieved a 25 percent or greater improvement at six weeks, which was sustained in all cases. Fourteen had an initial improvement of less than 25 percent, with only four (29 percent) showing later improvement (P < 0.0001). There was no relationship between results of the therapy and patient age, initial severity of symptoms, etiology of incontinence, and results of anal manometry, PNTML, and anal ultrasound. PFR is a physical therapy that should be considered as the initial treatment in patients with fecal incontinence. An improvement can be expected in up to 67 percent of patients. Initial good results can predict overall outcome.

Anal intercourse is an efficient mode of HIV transmission and may play a role in the heterosexual HIV epidemics of southern Africa. However, little information is available on the anal sex practices of heterosexual individuals in South Africa. To examine the occurrence of anal intercourse in samples drawn from community and clinic settings. Anonymous surveys collected from convenience samples of 2593 men and 1818 women in two townships and one large city sexually transmitted infection (STI) clinic in Cape Town. Measures included demographics, HIV risk history, substance use and 3-month retrospective sexual behaviour. A total of 14% (n = 360) men and 10% (n = 172) women reported engaging in anal intercourse in the past 3 months. Men used condoms during 67% and women 50% of anal intercourse occasions. Anal intercourse was associated with younger age, being unmarried, having a history of STI, exchanging sex, using substances, having been tested for HIV and testing HIV positive. Anal intercourse is reported relatively less frequently than unprotected vaginal intercourse among heterosexual individuals. The low prevalence of anal intercourse among heterosexual individuals may be offset by its greater efficiency for transmitting HIV. Anal sex should be discussed in heterosexual HIV prevention programming.

During an 18-month period to June 2012, 1732 anal chlamydia (Chlamydia trachomatis) tests were performed among men who have sex with men (MSM) at RPA Sexual Health in Sydney's inner west. Positive anal chlamydia samples were subsequently tested for lymphogranuloma venereum (LGV). Seventy-five (4.3%) anal samples were positive for chlamydia among 67 men during the study period. Anal symptoms were reported for 16 out of 75 (21.3%) of anal chlamydia episodes overall. Three episodes of LGV (all serovar L2b) were identified, all three of whom reported anal symptoms (100%, 95% confidence interval (CI): 29.2-100%). In contrast, only 13/72 (18.1%, 95% CI: 10.0-28.9%) of those with non-LGV anal chlamydia reported anal symptoms. LGV was not identified in any of 59 episodes of asymptomatic anal chlamydia (0%, 95% CI: 0-6.1%). Of those with LGV, two were known to be HIV-positive and one subsequently seroconverted to HIV within a year of the LGV diagnosis. Our findings suggest that routine LGV testing among MSM is not warranted, except among those with anal symptoms.

Objectivers To evaluate pain severity and distribution in relation to sleep difficulty in older adults. Design Population-based cross-sectional study Setting Community within a 5-mile radius of the study center at the Institute for Aging Research, Hebrew SeniorLife (HSL) in Boston Participants 765 participants of the Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly (MOBILIZE) Boston Study, aged 64 and older. Measurements Pain severity was measured using the Brief Pain Inventory (BPI), Pain Severity Subscale. Musculoskeletal pain distribution was grouped according to no pain, single site, ≥2 sites, and widespread pain (upper and lower extremities and back pain). We measured 3 aspects of sleep difficulty using items from the CESD-R (trouble getting to sleep, sleep more than usual, and restless sleep). Results Prevalence of trouble getting to sleep according to BPI severity was 17.8%, 19.7%, 32.0%, and 37.0% for the lowest to highest pain severity quartiles, respectively. Similar relationships between pain and sleep were observed across sleep measures according to pain severity and distribution. Adjusted for sociodemographic characteristics, chronic conditions and health behaviors, chronic pain was strongly associated with trouble sleeping (≥1d/week), (single site pain, OR=1.77, 95%CI, 1.10–2.87; multisite pain OR=2.38, 95% CI, 1.48–3.83; and widespread pain, OR=2.55, 95% CI, 1.43–4.54, each compared with no pain). Similar associations were observed for restless sleep and sleeping more than usual. With specific pain sites alone or in combination with other sites of pain, only modest associations were observed with sleep problems. Conclusion Widespread or other multisite pain and moderate to severe pain are strongly associated with sleep difficulty in older adults. Further research is needed to better understand the burden and consequences of pain-related sleep problems in the older population. PMID:21806564

Human immunodeficiency virus (HIV)-infected individuals have increased risk of anal intraepithelial neoplasia (AIN) and squamous cell carcinoma (SCC). Cytologic screening is invaluable in the detection of cervical neoplasia, therefore many clinicians have adopted anal cytology as part of anal cancer screening in patients at high-risk for anal neoplasia. The purpose of this study is to determine whether anal cytology is a valuable screening test for identifying AIN in HIV+ patients. The cohort included 228 HIV+ patients who underwent anal cancer screening with collection of 318 anal cytology specimens between January 2006 and December 2009. Of this group, 74 (32.5%) patients had associated anal biopsies within a 6-month period, with a total of 89 comparison cases. The anal cytology samples were classified using the 2001 Bethesda System terminology. The sensitivity of anal cytology in detecting ASC-US, AIN 1-3 or SCC was 93%. Cytology was 88% sensitive for detecting low-grade AIN (AIN 1), but only 20% sensitive for detecting high-grade AIN (AIN 2-3) or SCC. Atypical squamous cells of undetermined significance cases were distributed evenly between low- and high-grade AIN, with two cases having normal histology. Only six cases had negative cytology, all of which were associated with AIN on biopsy, for a false negative rate of 7%. Anal cytology is a good predictor of AIN, as confirmed by the high degree of sensitivity. However, there is poor correlation between the cytological and histological grade of AIN. Cytology underestimates the grade of dysplasia compared to the corresponding biopsy. Copyright © 2012 Wiley Periodicals, Inc., a Wiley company.

To compare the prevalence of abnormal anal cytology and high-risk human papillomavirus (HPV) among women with a history of HPV-related genital neoplasia with women without a history of HPV-related genital neoplasia. A cross-sectional cohort study was performed from December 2012 to February 2014. Women were recruited from outpatient clinics at an academic medical center. Women with a history of high-grade cervical, vulvar, or vaginal cytology, dysplasia, or cancer were considered the high-risk group. Women with no history of high-grade anogenital dysplasia or cancer were considered the low-risk group. Human immunodeficiency virus-positive women were excluded. Anal cytology and HPV genotyping were performed. Women with abnormal anal cytology were referred for high-resolution anoscopy. There were 190 women in the high-risk group and 83 in the low-risk group. The high-risk group was slightly older: 57 years compared with 47 years (P=.045); 21.7% of low-risk women had abnormal anal cytology compared with 41.2% of high-risk women (P=.006). High-risk HPV was detected in the anal canal of 1.2% of the low-risk group compared with 20.8% of the high-risk group (P<.001). Among women who underwent anoscopy, no anal dysplasia was detected in the low-risk group, whereas 13.4% in the high-risk group had anal dysplasia with 4.2% having anal intraepithelial neoplasia 2 or greater (P<.001). Human immunodeficiency virus-negative women with a history of lower genital tract neoplasia are more likely to have positive anal cytology, anal high-risk HPV, and anal intraepithelial neoplasia. Anal cancer screening should be considered for these high-risk women. II.

OBJECTIVES To assess the association between self-reported noncancer pain and 5-year mortality. DESIGN Cohort. SETTING Community-dwelling older adults. PARTICIPANTS Canadian Study of Health and Aging 1996 wave. MEASUREMENTS Registrar of Vital Statistics–established 5-year mortality. Noncancer pain was assessed using the 5-point verbal descriptor scale, dichotomized into no or very mild versus moderate, severe, or very severe pain. Frailty was the accumulation of health deficits. Cognitive status (Modified Mini-Mental State Examination) and depressed mood (five-item mental health screening questionnaire) were also assessed. Multivariable logistic regression and Cox proportional hazards were used to analyze the relationship between pain and 5-year mortality. RESULTS Of 5,703 participants, 4,694 (82.3%) had complete data for analysis; 1,663 of these (35.4%) reported moderate, severe, or very severe pain, and 1,343 (28.6%) had died at 5-year follow-up. Four hundred ninety-six of those who died (29.8%) reported moderate, severe, or very severe pain and 847 (27.9%) no or very mild pain. Multivariate logistic analysis found that individuals with moderate, severe, or very severe pain had lower odds of 5-year mortality than those with no or very mild pain (odds ratio = 0.78, 95% confidence interval (CI) = 0.66–0.92; P < .001). The risk of death was lower in persons reporting moderate or greater pain than in those with no or very mild pain (HR = 0.85, 95% CI = 0.75–0.96; P = .01). An interaction between pain and sex explained this effect. Men with pain were not significantly more likely than men without pain to die (HR = 1.00, 95% CI = 0.84–1.19; P = .99), whereas women without pain (HR = 0.54, 95% CI = 0.47–0.63; P < 0.01) and women with pain (HR = 0.40; CI = 0.33–0.47; P < .01) had less risk of death than men without and with pain, respectively. CONCLUSION Older women with pain were less likely to die within 5 years than older women without pain, men in pain, or men without pain. PMID:24320761

Research has shown that painful diabetic peripheral neuropathy (pDPN) is associated with worse health outcomes. However, among pDPN patients, few studies have examined the relationship between the severity of pain and health outcomes. The current project included pDPN patients (N=1506) from the 2006, 2007, and 2008 waves of the National Health and Wellness Survey. Health status (Short Form [SF]-12), work productivity (Work Productivity and Activity Impairment questionnaire), and health care resource use in the past 6 months were compared among pDPN patients with mild, moderate, and severe pain, adjusting for demographics and clinical characteristics. More than half (51.2%) of the patients reported their pain as severe, 45.2% reported moderate pain, and 3.7% reported mild pain. Those with severe pain reported significantly lower levels of health status, higher levels of work and activity impairment, and higher levels of resource use relative to the other groups. Annual per-patient costs for those with severe pain were $12,856, $3927, and $16,783 for direct, indirect, and total costs, respectively. Both direct and total costs were significantly higher in this group relative to both mild and moderate pain patients. These results suggest that pain severity contributes substantially to the health outcomes of pDPN patients and that greater resources should be allocated to the management of patients with severe pain.

We report the case of a 66-year-old man who presented with abdominal pain, blood in the stool, fever and chills. Laboratory tests were significant for leukocytosis and microcytic anemia. Abdominal imaging revealed a right colon mass and aortitis. Colonoscopy confirmed the right colon mass and also discovered a rectal mass, both adenocarcinomas. Treatment consisted of antibiotics, aortic repair, right hemi-colectomy and later trans-anal excision of the rectal mass. Blood cultures and the aortic specimen grew C. septicum . The patient improved and was doing well in follow up.

Facial pain is a cardinal symptom of chronic rhinosinusitis (CRS) with significant impacts on patient treatment selection, quality of life, and outcomes. The association between facial pain and CRS disease severity has not been systematically evaluated with validated, facial pain-specific questionnaires. Our objective was to measure pain location, severity, and interference in patients with CRS, and correlate these to the location and severity of radiographic evidence of disease. Patients with CRS were enrolled into a prospective, cross-sectional study. Patients completed the Brief Pain Inventory Short Form, which is a validated and widely used tool that measures pain location, severity, and interference with daily activities of living. The Lund-Mackay (L-M) computed tomography (CT) scoring system was used to operationalize the radiographic location and severity of inflammation. Facial pain location, severity, and interference scores were correlated to paranasal sinus opacification scores. Consecutive patients with CRS with nasal polyps (CRSwNP; n = 37) and CRS without nasal polyps (CRSsNP; n = 46) were enrolled. No significant relationship was found between the location and severity of reported facial pain and radiographic findings of disease for patients with either CRSwNP or CRSsNP. There was no difference in pain location between patients with and without radiographic disease in a given sinus. Facial pain in CRS is not predicted by the radiographic extent of disease. The location and severity of facial pain reported by the patient is not a reliable marker of the anatomic location and severity of sinonasal inflammation. Pain location should not necessarily be relied upon for guiding targeted therapy. © 2016 ARS-AAOA, LLC.

To determine the prevalence of HPV-induced lesions in the anal canal of women with cervical intraepithelial neoplasia (CIN) grade 2/3. A cross-sectional study was carried out from December 2008 to June 2009, in Pernambuco, northeastern Brazil. Only women with grade 2/3 CIN were included, and those who could not undergo anoscopy during their first visit were excluded. A cyttobrush was used for sample collection in order to identify HPV DNA through PCR and anal cytology. An anal biopsy was obtained in cases of abnormal anal cytology or major alterations in high resolution anoscopy (HRA). Thirty-two percent (n=37/115) of HRA were normal and 63.5% (n=73/115) showed acetowhite epithelium. Twenty-two percent (n=26/115) of anal cytologies were abnormal. Among the latter, 12.2% (n=14/26) were low-grade anal intraepithelial lesions and 3.4% (n=4/26) were high-grade anal intraepithelial lesions. Twenty-two anal biopsies were performed, 13.7% of which (n=3/22) were grade 2 anal intraepithelial neoplasia (AIN2) and 9% (n=2/22) were grade 3 AIN. Th HPV DNA was identified in 72.1% of cases (n=83/115). Women with CIN grade 2/3 showed a high prevalence of anal HPV infection and HPV-induced lesions.

The importance of the orientation of the electrode plates in recording the external anal sphincter EMG by non-invasive anal plug electrodes.

Two non-invasive anal plug electrodes of similar size have been compared, one with the electrode plates orientated circularly in the anal canal and the other with the plates in the long axis of the anal canal. There was a significant increase in the amplitude in the EMG signals recorded at rest and during squeeze from the external anal sphincter with a longitudinally placed electrode in 117 patients. Inappropriate contraction of the external anal sphincter when straining at stool was more readily detected using the longitudinal electrode in 52 patients investigated for intractable constipation. The longitudinal electrode detected the amplitude of the response to the elicitation of a pudeno-anal reflex more readily than the circular electrode. When in 12 of the 117 the pudeno-anal reflex EMG signal was either absent or not detected with the circumferential plug electrode, the longitudinal electrode detected the presence of a low amplitude response in 11 of these. When the non-invasive longitudinal electrode was compared to invasive fine wire stainless steel electrodes, a correlation was found for external anal sphincter resting EMG (r = 0.99, p less than 0.01), voluntary squeeze EMG (r = 0.99, p less than 0.001) and strain EMG (r = 0.91, p less than 0.01). The longitudinal anal plug electrode thus facilitates surface acquisition of EMG activity.

The purpose of this study was to document the prevalence and characteristics of physical pain in a sample of severely obese children and adolescents. In this retrospective chart review, primary measures included current and past pain, pain intensity, and pain characteristics during a 5-minute walk test. Pain assessments for 74 patients (mean age 11.7 years; 53% female; 41% African American) were conducted by a physical therapist. Past pain was reported by 73% of the sample, with 47% reporting pain on the day of program enrollment. Although average pain intensity was moderate (M = 5.5/10), alarmingly, 42% of those with current pain reported severe pain (6/10 to 10/10). Overall, pain occurred primarily in the lower extremities and with physical activity. Patients reporting current pain had a significantly higher body mass index than those reporting no pain. These findings suggest that pain is common in severely obese youth, and furthermore, that pain should be recognized as a comorbidity of pediatric obesity. Routinely screening severely obese children and adolescents for pain presence and intensity is recommended. PMID:24723992

In US men, the incidence of anal cancer, the primary cause of which is human papillomavirus (HPV) infection, has increased almost 3-fold in 3 decades; however, little is known about the epidemiology of anal HPV infection, especially in heterosexual men. In 2 US cities, behavioral data and anal biological specimens were collected from 253 men who acknowledged having engaged in sexual intercourse with a woman during the preceding year. On the basis of DNA analysis, overall prevalence of anal HPV infection was found to be 24.8% in 222 men who acknowledged having had no prior sexual intercourse with men. Of the men with anal HPV infection, 33.3% had an oncogenic HPV type. Risk factors independently associated with anal HPV were lifetime number of female sex partners and frequency of sex with females during the preceding month. These results suggest that anal HPV infection may be common in heterosexual men.

Prophylactic HPV vaccination and anal cancer.

The incidence of anal cancer is increasing. High risk populations include HIV-positive men who have sex with men (MSM), HIV-negative MSM, HIV-positive women and heterosexual men and women with a history of cervical cancer. HPV has been detected in over 90% of anal cancers. HPV16 is the most common genotype detected in about 70% of anal cancers. The quadrivalent HPV (qHPV) vaccine has been demonstrated to prevent vaccine associated persistent anal HPV infections as well as anal intraepithelial neoplasia grades 2-3 (AIN2+) in young MSM not previously infected. A retrospective analysis also suggests that qHPV vaccination of older MSM treated for AIN2+ may significantly decrease the risk of recurrence of the AIN2+. The HPV types detected in anal cancer are included in the 9-valent vaccine. Thus, the 9-valent HPV vaccine, when administered to boys and girls prior to the onset of sexual activity, should effectively prevent anal cancer.

While the association between smoking and HPV infection, cervical cancer, and anal cancer has been well studied, evidence on the association between cigarette smoking and anal warts is limited. The purpose of this study was to investigate if cigarette smoking status influences the size of anal warts over time in HIV-infected women in a sample of 976 HIV-infected women from the Women’s Interagency HIV Study (WIHS). A linear mixed model was used to determine the effect of smoking on anal wart size. Even though women who were currently smokers had larger anal warts at baseline and slower growth rate of anal wart size after each visit than women who were not current smokers, there was no association between size of anal wart and current smoking status over time. Further studies on the role of smoking and interaction between smoking and other risk factors, however, should be explored. PMID:23155099

[The artificial sphincter: therapy for faecal incontinence].

Baumgartner, U

Faecal incontinence (FI) challenges a patient's professional, social and sexual life. Often the patient becomes depressive and socially isolated. If able to break open for therapy the patient should receive as first line a conservative treatment (like dietary measures, pelvic re-education, biofeedback, bulking agents, irrigation). When is the time to implant an artificial anal sphincter? If conservative therapy fails as well as surgical options (like a sphincteroplasty - if indicated a reconstruction of the pelvic floor if insufficient, or a sacral nerve stimulation) an ultimo surgical procedure should be offered to appropriate and compliant patients: an artificial anal sphincter. Worldwide, there are two established devices on the market: the artificial bowel sphincter® (ABS) from A. M. S. (Minnetonka, MN, USA) and the soft anal band® from A. M. I. (Feldkirch, Austria). How to implant the artificial anal sphincter? Both devices consist of a silicon cuff which can be filled with fluid. Under absolute aseptic conditions this cuff is placed in the lithotomy position by perianal incisions around the anal canal below the pelvic floor. A silicon tube connects the anal cuff with a reservoir (containing fluid) which is placed either behind the pubis bone in front of the bladder (ABS) or below the costal arch (anal band). With a pump placed in the scrotum/labia (ABS) or by pressing the balloon (anal band) in both types operated by the patient the fluid is shifted forth and back between the anal cuff and the reservoir closing or opening the anal canal. Both systems are placed completely subcutaneously. Both devices improve significantly the anal continence. Both systems have a high rate of reoperations. However, the causes for the redos are different. The ABS is associated with high infection and anal penetration rates of the cuff leading to an explantation rate to up to 60 % of the implants. This kind of complication seems to be much lower with the anal band. The major problem in the anal band is a defunctioning valve which occasionally has to be replaced. Despite these problems both types of artificial anal sphincters improve faecal incontinence significantly and, thus, quality of life of incontinent patients.

Impact of the HIV Epidemic on the Incidence Rates of Anal Cancer in the United States

PubMed Central

2012-01-01

Background The risk of anal cancer is substantially increased in HIV-infected individuals. Thus, the HIV epidemic may have influenced the increasing anal cancer trends in the United States. We estimated the impact of the HIV epidemic on trends in anal cancer incidence in the United States during 1980–2005. Methods Data on anal cancer cases with and without AIDS were obtained from the HIV/AIDS Cancer Match Study. The number of HIV-infected anal cancer cases without AIDS was estimated from the number of anal cancers occurring before diagnosis of AIDS. The proportion of anal cancer cases with HIV infection in the general population was calculated. We estimated temporal trends in the incidence rates of anal cancer in the general population overall and after exclusion of HIV-infected cancer cases by calculating annual percent changes and 95% confidence intervals (CIs) using a Joinpoint log-linear model. All incidence rates were standardized to the 2000 US population by age, sex, and race. Results During 1980–2005, of the 20 533 estimated anal cancer cases, 1665 (8.1%) were HIV-infected. During 2001–2005, the proportion of anal cancer cases with HIV infection was the highest—1.2% (95% CI = 0.93 to 1.4%) among females and 28.4% (95% CI = 26.6 to 29.4%) among males. During 1980–2005, HIV infection did not have an impact on the trends in anal cancer among females (incidence rates increased by 3.3% [95% CI = 3.0 to 3.7%] annually overall, and by 3.3% [95% CI = 2.9 to 3.6%] annually without HIV-infected anal cancer cases) but had a strong impact on the trends in anal cancer among males (incidence rates increased by 3.4% [95% CI = 2.9 to 3.9%] annually overall, and by 1.7% [95% CI = 1.2 to 2.3%] annually without HIV infection). Conclusion During 1980–2005, the increasing anal cancer incidence rates in the United States were strongly influenced by the HIV epidemic in males but were independent of HIV infection in females.

Anorectal emergencies.

2016-07-14

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.

2011-05-01

The objective of this study was to estimate the prevalence of cytological abnormalities of the anal mucosa in women with positive cervical cytology, but without macroscopic anal lesion. Ultimately we postulated if the anal mucosa may be a reservoir of HPV, which would allow the reinfection of cervix. Forty-nine patients with abnormal cervical cytology were selected for this work. In a period not exceeding one week of collecting cervix cytology, two swab specimens of the anal canal were also collected. Women diagnosed with cervical HSIL by Pap smear were referred for colposcopy with biopsy of the lesions, to confirm the cytologic diagnosis and ablation of the lesion. We demonstrated a high prevalence of anal squamous intraepithelial lesions in patients with cervical squamous intraepithelial lesions (29 of the total of 49 patients = 59.2%). Of the 20 cases of cervical LSIL, 11 (55%) had abnormal anal cytology. Of the 26 cases with cervical HSIL, 16 (61.5%) had abnormal anal cytology. So, there was a discrete higher prevalence of abnormal anal cytology in cases of high-grade cervical squamous lesions (cervical HSIL). These results help to support the hypothesis that the anal mucosa is a reservoir of HPV, which can be a source of re-infection for the cervix. However, there was no significant association between the practice of anal sex and the prevalence of anal cytological abnormalities. These facts are epidemiologically important for future programs for population eradication of cervical lesions related to HPV. Diagn. Cytopathol. 2011;39:323-327. © 2010 Wiley-Liss, Inc.

Anal disorders are largely underestimated in general practice. Studies have shown patients conceal anal symptoms leading to late diagnosis and treatment. Management by general practitioners is poorly described. The aim of this study is to assess the prevalence of anal symptoms and their management in general practice. In this prospective, observational, national study set in France, all adult patients consulting their general practitioner during 2 days of consultation were included. Anal symptoms, whether spontaneously revealed or not, were systematically collected and assessed. For symptomatic patients, the obstacles to anal examination were evaluated. The general practitioner's diagnosis was collected and a proctologist visit was systematically proposed in case of anal symptoms. If the proctologist was consulted, his or her diagnosis was collected. From October 2014 to April 2015, 1061 patients were included by 57 general practitioners. The prevalence of anal symptoms was 15.6% (95% CI: 14-18). However, 85% of these patients did not spontaneously share their symptoms with their doctors, despite a discomfort rating of 3 out of 10 (range 1-5). Although 65% of patients agreed to an anal examination, it was not proposed in 45% of cases with anal symptoms. Performing the examination was associated with a significantly higher diagnosis rate of 76% versus 20% (p < 0.001). Proctologist and general practitioner diagnoses were consistent in 14 out of 17 cases. Patients' concealed anal symptoms are significant in general practice despite the impact on quality of life. Anal examination is seldom done. Improved training of general practitioners is required to break the taboo.

The aims of this paper are to generate estimates of the association between the severity and frequency of pain in Spain and (i) labor force participation and workforce status and (ii) patterns of absenteeism and presenteeism for the employed workforce. Data are from the internet-based 2010 National Health and Wellness Survey (NHWS). This survey covers both those who report experiencing pain in the last month as well as the no-pain population. An estimated 17.25% of adults in Spain report experiencing pain in the past month. A series of regression models are developed with the no-pain group as the reference category. The impact of pain, categorized by severity and frequency, is assessed within a labor supply framework for (i) labor force participation and (ii) absenteeism and presenteeism. Both binomial and multinomial logistic models are estimated. The results demonstrate that severe and moderate pain has a significant, substantive, and negative association with labor force participation and, together with the experience of mild pain, a substantive impact on absenteeism and presenteeism within the employed workforce. Compared to no-pain controls, the strongest association is seen in the case of severe pain, notably severe daily pain and labor force participation (odds ratio 0.363; 95% CI: 0.206-0.637). The association of severe pain with labor force participation is also significant (odds ratio 0.356; 95% CI: 0.217-0.585). There is a clear gradient in the association of pain severity and frequency with labor force participation. The impact of pain is far greater than the potential impact of other health status measures (e.g., chronic comorbidities and BMI). Labor force participation is also adversely associated with pain experience. Persons reporting severe daily pain are far more likely not to be in the labor force (relative probabilities 0.339 vs 0.611). The experience of pain, notably severe and frequent pain, also outstrips the impact of other health status factors in absenteeism and presenteeism. In the former case, the odds ratio associated with severe daily pain is 16.216 (95% CI: 5.127-51.283), which contrasts to the odds ratio for the Charlson comorbidity index of 1.460 (95%CI: 1.279-1.666). Similar results hold for presenteeism. The contribution of moderate and mild pain to absenteeism and presenteeism is more marked than for labor force participation. The experience of pain, in particular severe daily pain, has a substantial negative impact both on labor force participation in Spain as well as reported absenteeism and presenteeism. As a measure of health status, it clearly has an impact that outstrips other health status measures. Whether or not pain is considered as a disease in its own right, the experience of chronic pain, as defined here, presents policy-makers with a major challenge. Programs to relieve the burden of pain in the community clearly have the potential for substantial benefits from societal, individual, and employer perspectives.

Anal cancer and intraepithelial neoplasia screening: A review

PubMed Central

Leeds, Ira L; Fang, Sandy H

2016-01-01

This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

This study was conducted to provide normal reference features for canine and feline anal sacs using ultrasound, low-field magnetic resonance imaging (MRI) and radiograph contrast as diagnostic imaging tools. A total of ten clinically normal beagle dogs and eight clinically normally cats were included. General radiography with contrast, ultrasonography and low-field MRI scans were performed. The visualization of anal sacs, which are located at distinct sites in dogs and cats, is possible with a contrast study on radiography. Most surfaces of the anal sacs tissue, occasionally appearing as a hyperechoic thin line, were surrounded by the hypoechoic external sphincter muscle on ultrasonography. The normal anal sac contents of dogs and cats had variable echogenicity. Signals of anal sac contents on low-field MRI varied in cats and dogs, and contrast medium using T1-weighted images enhanced the anal sac walls more obviously than that on ultrasonography. In conclusion, this study provides the normal features of anal sacs from dogs and cats on diagnostic imaging. Further studies including anal sac evaluation are expected to investigate disease conditions.

Diagnosis and treatment of acute low back pain.

PubMed

Casazza, Brian A

2012-02-15

Acute low back pain is one of the most common reasons for adults to see a family physician. Although most patients recover quickly with minimal treatment, proper evaluation is imperative to identify rare cases of serious underlying pathology. Certain red flags should prompt aggressive treatment or referral to a spine specialist, whereas others are less concerning. Serious red flags include significant trauma related to age (i.e., injury related to a fall from a height or motor vehicle crash in a young patient, or from a minor fall or heavy lifting in a patient with osteoporosis or possible osteoporosis), major or progressive motor or sensory deficit, new-onset bowel or bladder incontinence or urinary retention, loss of anal sphincter tone, saddle anesthesia, history of cancer metastatic to bone, and suspected spinal infection. Without clinical signs of serious pathology, diagnostic imaging and laboratory testing often are not required. Although there are numerous treatments for nonspecific acute low back pain, most have little evidence of benefit. Patient education and medications such as nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants are beneficial. Bed rest should be avoided if possible. Exercises directed by a physical therapist, such as the McKenzie method and spine stabilization exercises, may decrease recurrent pain and need for health care services. Spinal manipulation and chiropractic techniques are no more effective than established medical treatments, and adding them to established treatments does not improve outcomes. No substantial benefit has been shown with oral steroids, acupuncture, massage, traction, lumbar supports, or regular exercise programs.

2016-01-01

To explore the impact of interactions between smoking and symptoms of posttraumatic stress disorder (PTSD) on pain intensity, psychological distress, and pain-related functioning in patients with orofacial pain, a retrospective review was conducted of data obtained during evaluations of 610 new patients with a temporomandibular disorder who also reported a history of a traumatic event. Pain-related outcomes included measures of pain intensity, psychological distress, and pain-related functioning. Main effects of smoking status and PTSD symptom severity on pain-related outcomes were evaluated with linear regression analyses. Further analyses tested interactions between smoking status and PTSD symptom severity on pain-related outcomes. PTSD symptom severity and smoking predicted worse pain-related outcomes. Interaction analyses between PTSD symptom severity and smoking status revealed that smoking attenuated the impact of PTSD symptom severity on affective distress, although this effect was not found at high levels of PTSD symptom severity. No other significant interactions were found, but the present results identifying smoking as an ineffective coping mechanism and the likely role of inaccurate outcome expectancies support the importance of smoking cessation efforts in patients with orofacial pain. Smoking is a maladaptive mechanism for coping with pain that carries significant health- and pain-related risks while failing to fulfill smokers’ expectations of affect regulation, particularly among persons with orofacial pain who also have high levels of PTSD symptom severity. Addressing smoking cessation is a critical component of comprehensive treatment. Further research is needed to develop more effective ways to help patients with pain and/or PTSD to replace smoking with more effective coping strategies. PMID:27486084

Walhart, Tara

2015-01-01

Persistent oncogenic human papillomavirus (HPV) infection increases the probability that precancerous anal high-grade squamous intraepithelial lesions will progress to invasive anal cancer. Anal neoplasia associated with HPV disproportionately affects HIV-infected individuals, especially men who have sex with men. Prevention is limited to HPV vaccine recommendations, highlighting the need for new treatments. The purpose of this review is to provide HIV information to nurse clinical scientists about HPV-related cancer to highlight the connection between: (a) HPV biology and pathogenesis and (b) the development of drugs and novel therapeutic methods using high-throughput screening. PubMed and CINAHL were used to search the literature to determine HPV-related epidemiology, biology, and use of high-throughput screening for drug discovery. Several events in the HPV life cycle have the potential to be developed into biologic targets for drug discovery using the high-throughput screening technique, which has been successfully used to identify compounds to inhibit HPV infections.

Anal intraepithelial neoplasia is considered a precursor lesion of anal squamous carcinoma. The population with increased risk of this conditions are immunocompromised individuals, especially HIV-infected, with anal sex practices. The aim of this study was to describe the sexual habits of patients who were seen in sexually transmitted infections (STIs) consult in our service in whom anal cytology was performed as well as the association of anal dysplasia to other STIs. We performed a retrospective cohort study that included those patients in whom, according to our protocol, anal cytology was performed between 2008 and 2011. Also we conducted a survey on sexual habits and screening for other STIs. Finally, we conducted a descriptive and analytical study assessing bivariate distribution of cytological alterations and grade of anal dysplasia. A total of 347 anal cytologies were performed, and 48.1% were abnormal. Statistically significant differences were found between the presence of condylomata perianal/endoanal, HIV infection, Chlamydia trachomatis infection and the presence of cytologic alterations. There was a high incidence of anal dysplasia in our group of individuals with risky sexual habits; however, it is probably underdiagnosed due to its subclinical nature and lack of a well-established screening protocol.

Background The incidence of anal cancer is on the rise among HIV-infected men who have sex with men (MSM). Given the increasing availability of screening, this study explored anal cancer screening awareness and behaviors among MSM infected with HIV. Methods In-depth interviews were conducted with 58 MSM infected with HIV. Results Other than 2 participants treated for anal cancer and 3 treated for precancerous anal lesions, the majority of participants had never heard of anal cancer. Men reported lack of awareness and recommendations from their health care professionals as the greatest barriers to screening. Upon learning about their risk for anal cancer and the availability of screening, the men were eager to discuss screening with their physicians. Participants provided numerous recommendations for future interventions, including training health care professionals to promote screening, disseminating information pertaining to anal cancer through social networks, and creating media campaigns to raise awareness about the need to screen for this type of cancer. Conclusions Future intervention work should focus on ensuring that health care professionals, particularly among HIV/primary care specialists, promote screening for anal dysplasia. It is critical that intervention methods use a community-based approach to raise awareness about the need to screen for anal cancer, especially among MSM infected with HIV. PMID:27009457

Approximately 20% of hospitalized Medicare beneficiaries are discharged from the hospital to skilled nursing facilities (SNFs); and up to 23% of SNF patients return to the hospital within 30 days of hospital discharge, with pain as one of the most common symptoms precipitating hospital readmission. We sought to examine the prevalence of moderate to severe pain at hospital discharge to SNF, the incidence of new moderate to severe pain (relative to prehospitalization), and satisfaction with pain management among older acute care patients discharged to SNF. Structured patient interviews were conducted with 188 Medicare beneficiaries discharged to 23 area SNFs from an academic medical center. Pain level (0-10) and satisfaction with pain management were assessed upon hospital admission, discharge, and within 1 week after transition to SNF. There was a high prevalence of moderate to severe pain at each time point including prehospital (51%), hospital discharge (38%), and following SNF admission (53%). Twenty-eight percent of participants reported new moderate to severe pain at hospital discharge, whereas 44% reported new moderate to severe pain following SNF admission. Most participants reported being "satisfied" with their pain treatment, even in the context of moderate to severe pain. Moderate to severe pain is a common problem among hospitalized older adults discharged to SNF and continues during their SNF stay. Pain assessment and management should involve a specific, planned process between hospital and SNF clinicians at the point of care transition, even if patients express "satisfaction" with current pain management. © The Author 2015.

Background. Health outcomes are often contingent on how effective the individual is able to manage existent illness-related symptoms. This is all the more relevant among chronic pain patients. Objective. This study aimed to identify indicators of pain treatment satisfaction among middle-aged and older adults (N = 150) receiving outpatient treatment from a comprehensive cancer center. Methods. Patients were surveyed on questions assessing pain treatment satisfaction, pain severity, and additional social characteristics. Results. Descriptive data showed that middle-aged adults reported more pain locations, greater pain severity, and less satisfaction with pain treatment. A multivariate model was specified, showing older adults being more satisfied with their pain treatment. For the middle-aged adults, treatment satisfaction was generally lower with greater pain severity. This counters that for the older adults, where treatment satisfaction remained consistent despite increased levels of pain severity. Conclusion. These findings address an important issue regarding how pain is experienced across the life course. This suggests that general assumptions cannot be made about the health outcomes of older adults. Beyond the descriptive definitions of pain, there remains the need to develop models that account for determinants that may account for the pain experience among a diverse adult population.

Cutaneous allodynia (pain from a non-painful stimulus) is a sign that can be observed among women with chronic pelvic pain. Dysmenorrhea is recognized as a common cause of chronic pelvic pain in women. This study was conducted to explore the frequency of allodynia and the relationship between allodynia and severe dysmenorrhea. We enrolled women in this study if they had experienced chronic pelvic pain for more than six months. Women provided information regarding their chronic pelvic pain and menstrual function, specifically the severity of their menstrual pain. In addition to a gynaecological assessment, women were tested for allodynia and pain pressure thresholds. Abdominal allodynia was present in 62.1% of 181 women who participated. Women with allodynia had a significantly greater rate of severe dysmenorrhea and significantly greater duration of severe dysmenorrhea. Pain pressure thresholds were demonstrated to decrease significantly in relation to increasing duration of severe dysmenorrhea. There is a greater frequency of chronic pain among women with a history of severe dysmenorrhea. Women who experienced prolonged severe dysmenorrhea were shown to have a progressive increase in pain sensitivity (reflected in reduced pain pressure thresholds). These findings support efforts to manage dysmenorrhea early in a woman's life with approaches to suppress menstrual function.

Background Pain hypervigilance is an important aspect of the fear-avoidance model of pain that may help explain individual differences in pain sensitivity among persons with knee osteoarthritis (OA). Purpose The purpose of this study was to examine the contribution of pain hypervigilance to clinical pain severity and experimental pain sensitivity in persons with symptomatic knee OA. Methods We analyzed cross-sectional data from 168 adults with symptomatic knee OA. Quantitative sensory testing was used to measure sensitivity to heat pain, pressure pain, and cold pain, as well as temporal summation of heat pain, a marker of central sensitization. Results Pain hypervigilance was associated with greater clinical pain severity, as well as greater pressure pain. Pain hypervigilance was also a significant predictor of temporal summation of heat pain. Conclusions Pain hypervigilance may be an important contributor to pain reports and experimental pain sensitivity among persons with knee OA. PMID:24352850

Little is known about human papillomavirus (HPV) infection and genotypes when considering both anatomic site and human immunodeficiency virus (HIV) status among men who have sex with men (MSM) in low- and middle-income countries. A cross-sectional study was conducted among MSM in Beijing, China. HIV serostatus was determined, and genital and anal HPV genotyping were performed from respective swabs. Of 1155 MSM, 817 (70.7%) had testing for genital (611; 52.9%) and/or anal (671; 58.1%) HPV. Preference for insertive anal sex (adjusted odds ratio [aOR], 2.60; 95% confidence interval [CI], 1.42-4.75) and syphilis (aOR, 1.50; 95% CI, 1.01-2.23) were associated with genital HPV. Inconsistent condom use during receptive anal sex (aOR, 1.82; 95% CI, 1.17-2.84), and HIV seropositivity (aOR, 2.90; 95% CI, 1.91-4.42) were associated with anal HPV. Among 465 (40.3%) MSM with specimens from both anatomic sites, anal HPV (68%) was more common than genital HPV (37.8%). Prevalence of anal HPV was higher among HIV-infected than uninfected MSM (P < 0.01). Some oncogenic HPV types were more commonly found at the anal site of HIV-infected MSM (P < 0.01). Human papillomavirus is highly prevalent among Chinese MSM. Anal HPV was more common than genital HPV, and HIV seropositivity was associated with oncogenic HPV types at the anal site.

Abstract Identifying factors, including human papillomavirus (HPV) genotypes, associated with abnormal anal cytology in HIV-infected women have implications for anal squamous cell cancer (SCC) prevention in HIV-infected women. Anal and cervical samples were collected for cytology, and tested for high-(HR-HPV) and low-risk HPV (LR-HPV) genotypes in a cross-sectional analysis of the IPEC Women's HIV Cohort (Rio de Janeiro, Brazil). Multivariate log-binomial regression models estimated prevalence ratios for factors associated with abnormal anal cytology [≥atypical squamous cells of undetermined significance, (ASC-US)]. Characteristics of the 863 participants included: median age 42 years, 57% non-white, 79% current CD4+ T-cell count >350 cells/mm3, 53% HIV-1 viral load <50 copies/mL, median ART duration 5.8 years. Fifty-one percent of anal specimens contained ≥1 HR-HPV genotype; 31% had abnormal anal cytology [14% ASC-US, 11% low-grade squamous intra-epithelial lesion, (LSIL); 2% atypical squamous cells-cannot exclude high-grade SIL (ASC-H); 4% high-grade SIL/cancer (HSIL+)]. In multivariate analysis, cervical LSIL+, nadir CD4+ T-cell count ≤50 cells/mm3, HIV-1 viral load ≥50 copies/mL, and anal HPV 6, 11, 16, 18, 33, 45, 52, 56, and 58 were associated with ≥anal ASC-US (p<0.05). Abnormal anal cytology and HR-HPV prevalences were high. HIV-infected women with cervical LSIL+, low nadir CD4+ counts, or detectable HIV-1 viral loads should be a particular focus for enhanced anal SCC screening efforts. PMID:25361401

High-grade intraepithelial neoplasia is known to progress to invasive squamous-cell carcinoma of the anus. There are limited reports on the rate of progression from high-grade intraepithelial neoplasia to anal cancer in HIV-positive men who have sex with men. The purpose of this study was to describe in HIV-positive men who have sex with men with perianal high-grade intraepithelial neoplasia the rate of progression to anal cancer and the factors associated with that progression. This was a prospective cohort study. The study was conducted at an outpatient clinic at a tertiary care center in Toronto. Thirty-eight patients with perianal high-grade anal intraepithelial neoplasia were identified among 550 HIV-positive men who have sex with men. All of the patients had high-resolution anoscopy for symptoms, screening, or surveillance with follow-up monitoring/treatment. We measured the incidence of anal cancer per 100 person-years of follow-up. Seven (of 38) patients (18.4%) with perianal high-grade intraepithelial neoplasia developed anal cancer. The rate of progression was 6.9 (95% CI, 2.8-14.2) cases of anal cancer per 100 person-years of follow-up. A diagnosis of AIDS, previously treated anal cancer, and loss of integrity of the lesion were associated with progression. Anal bleeding was more than twice as common in patients who progressed to anal cancer. There was the potential for selection bias and patients were offered treatment, which may have affected incidence estimates. HIV-positive men who have sex with men should be monitored for perianal high-grade intraepithelial neoplasia. Those with high-risk features for the development of anal cancer may need more aggressive therapy.

In a previous study, the external anal sphincter (EAS) in dogs, known to consist of skeletal muscle fibers, was proved to contain bundles of smooth muscle fibers in between as well. Cause of electric activity in the external anal and urethral sphincters is not known; the current study investigated this point. Slices from external anal and urethral sphincters of 21 cadavers (12 male, 9 female). Eighth were fully and mat wide neonates, 13 were adults, were stained with hematoxylin and eosin, Masson's trichrome and succinic dehydrogenase, and examined microscopically. Eighteen healthy volunteers, electromyography activity of their external anal and urethral sphincters was recorded at rest, on coughing, after pudendal nerve block and after drotaverine administration, (a smooth muscle relaxant). Anal and urethral pressures were also measured. Microscopic studies have shown that both external anal and urethral sphincters were formed of bundles of smooth muscle fibers present in between the skeletal muscle fibers. Bilateral pudendal nerve block did not abolish the external anal or the urethral sphincters electromyography activity at rest, or on coughing, and did not cause significant anal or urethral pressure changes (p > .05). Drotaverine administration lead to disappearance of the electromyography activity and significant decline of the anal and urethral pressures (p < .05). The results were reproducible when the tests were repeated in the same subject. Histologic examination revealed the presence of smooth muscle fibers, between the skeletal fibers of the external anal and urethral sphincters. Evidence suggests that the smooth muscle fibers are the source of the electric activity of the sphincters and might explain some physiologic phenomena such as the external anal contraction on rectal distension or on coughing.

To estimate the prevalence of anal dysplasia in immunocompetent women with cervical intraepithelial dysplasia. We did a prospective cohort study, in which we enrolled 166 women with gynecological pathology related to human papilloma virus (HPV) infection. All patients underwent an anal cytology and HPV detection. Statistical analysis with a 95% confidence interval was used for prevalence calculations. A Χ2 test and Fisher's exact one were used to determine differences between groups of qualitative variables. Differences between normally distributed and non-normally distributed groups in quantitative variables were accounted for using Student's t-test or Mann-Whitney's U test, respectively. Out of the 166 patients studied, high risk HPV in the anal canal was detected in 107 (64.46%) cases. The most prevalent genotype observed was non 16/18 high risk HPV, present in 54 (50.47%) patients. There was no a significant association with smoking, use of condom, anal intercourse, or anal benign pathology. However, a significant correlation between the presence of high risk HPV in the anal canal and the antecedent of condylomas was observed (p=0.047) (CI95%: 1.00%-12.58%). Women with cervical intraepithelial neoplasia (CIN) grade 1 had a significantly increased presence of high risk HPV in the anal canal (p=0.044). Out of the 166 women, 6 (3.61%) had abnormal anal cytology results, and were referred to high-resolution anoscopy. Anal biopsy was performed in these six cases. In 2 patients the biopsy reported low-grade Anal Intraepithelial Neoplasia: 1.20% (0.15%-4.28%). Women with cervical intraepithelial dysplasia have 1.20% prevalence of anal intraepithelial neoplasia, so that it does not seem necessary to screen this population. Copyright © 2017 Elsevier B.V.

The human papilloma virus is the leading cause of anal squamous cell carcinoma. Cytological screening may reduce the associated morbidity and mortality. The aim of the study was to estimate the agreement between anal cytological examination, histopathology and anoscopic visual impression. A prospective study of patients who underwent anal dysplasia screening between 2011 and 2015, in a proctology clinic of a tertiary referral center. During the study period, 141 patients (91% men, 87% with HIV infection) underwent 175 anal cytology tests. Of these, 33% were negative for intraepithelial lesions or malignancy (NILM), 22% were atypical squamous cells of uncertain significance (ASCUS), 33% were low-grade squamous intraepithelial lesion (LSIL) and 12% were high-grade squamous intraepithelial lesion (HSIL). With regard to anoscopic visual impression, 46% of patients had no lesions and excision/biopsy of the identified lesions was performed in the remaining patients. The weighted kappa-agreement between abnormal cytological results and anoscopic visual impression was moderate (k = 0.48). The weighted kappa-agreement between simultaneous anal cytological examinations and anal histopathologic findings was low (kappa = 0.20). With regard to the histological examination of cases with HSIL or superficially invasive squamous cell carcinoma, 64% of patients had dysplasia of a lower grade according to the cytological analysis (6 ASCUS, 18 LSIL and 4 NILM). There was a poor correlation between anal cytology, histopathology and anoscopic visual impression and a high number of histological studies of HGD that were of a lower dysplastic degree according to the cytological examination. Therefore, anal cytology screening should not be used as the sole method of anal dysplasia screening.

High-resolution anoscopy or expectant management for anal intraepithelial neoplasia for the prevention of anal cancer: is there really a difference?

High-resolution anoscopy has been shown to improve identification of anal intraepithelial neoplasia but a reduction in progression to anal squamous-cell cancer has not been substantiated when serial high-resolution anoscopy is compared with traditional expectant management. The aim of this study was to compare high-resolution anoscopy versus expectant management for the surveillance of anal intraepithelial neoplasia and the prevention of anal cancer. This is a retrospective review of all patients who presented with anal squamous dysplasia, positive anal Pap smears, or anal squamous-cell cancer from 2007 to 2013. This study was performed in the colorectal department of a university-affiliated, tertiary care hospital. Included patients had biopsy-proven anal intraepithelial neoplasia from 2007 to 2013. Patients were treated with high-resolution anoscopy with ablation or standard anoscopy with ablation. Both groups were treated with imiquimod and followed every 6 months indefinitely. The incidence of anal squamous-cell cancer in each group was the primary end point. From 2007 to 2013, 424 patients with anal squamous dysplasia were seen in the clinic (high-resolution anoscopy, 220; expectant management, 204). Three patients (high-resolution anoscopy, 1; expectant management, 2) progressed to anal squamous-cell cancer; 2 were noncompliant with follow-up and with HIV treatment, and the third was allergic to imiquimod and refused to take topical 5-fluorouracil. The 5-year progression rate was 6.0% (95% CI, 1.5-24.6) for expectant management and 4.5% (95% CI, 0.7-30.8) for high-resolution anoscopy (p = 0.37). This was a retrospective review. There is potential for selection and referral bias. Because of the rarity of the outcome, the study may be underpowered. Patients with squamous-cell dysplasia followed with expectant management or high-resolution anoscopy rarely develop squamous-cell cancer if they are compliant with the protocol. The cost, morbidity, and value of high-resolution anoscopy should be further evaluated in lieu of these findings.

There is uncertainty about the nature and specificity of physical signs following anal child sexual abuse. The study investigates the extent to which physical findings discriminate between children with and without a history of anal abuse. Retrospective case note review in a paediatric forensic unit. all eligible cases from 1990 to 2007 alleging anal abuse. all children examined anally from 1998 to 2007 with possible physical abuse or neglect with no identified concern regarding sexual abuse. Fisher's exact test (two-tailed) was performed to ascertain the significance of differences for individual signs between cases and controls. To explore the potential role of confounding, logistic regression was used to produce odds ratios adjusted for age and gender. A total of 184 cases (105 boys, 79 girls), average age 98.5 months (range 26 to 179) were compared with 179 controls (94 boys, 85 girls) average age 83.7 months (range 35-193). Of the cases 136 (74%) had one or more signs described in anal abuse, compared to 29 (16%) controls. 79 (43%) cases and 2 (1.1%) controls had >1 sign. Reflex anal dilatation (RAD) and venous congestion were seen in 22% and 36% of cases but <1% of controls (likelihood ratios (LR) 40, 60 respectively), anal fissure in 14% cases and 1.1% controls (LR 13), anal laxity in 27% cases and 3% controls (LR 10).Novel signs seen significantly more commonly in cases were anal fold changes, swelling and twitching. Erythema, swelling and fold changes were seen most commonly within 7 days of last reported contact; RAD, laxity, venous congestion, fissure and twitching were observed up to 6 months after the alleged assault. Anal findings are more common in children alleging anal abuse than in those presenting with physical abuse or neglect with no concern about sexual abuse. Multiple signs are rare in controls and support disclosed anal abuse.

The role of Human Papilloma Virus (HPV) vaccination in the prevention of anal cancer in individuals with Human Immunodeficiency Virus-1 (HIV-1) infection

PubMed Central

2013-01-01

The incidence of anal cancer is increasing in the general population and especially in high-risk groups. A total of 90% of anal cancers are caused by human papilloma virus (HPV) infection of the anal canal. Similar to cervical cancer, anal cancer progresses through a predictable series of premalignant stages before resulting in invasive cancer; this process begins with persistent HPV infection. The HPV vaccine represents a promising strategy to combat the increasing incidence of anal cancer. Human Immunodeficiency Virus (HIV) predisposes people to persistent HPV infection, dysplasia, and subsequent anal cancer. Patients infected with HIV should be targeted for vaccination against HPV. There are difficulties in targeting this population, the most notable being that the optimal age for vaccination is prior to identification with any high-risk groups. Universal vaccination against HPV represents the best strategy to achieve maximum protection against anal cancer in high-risk groups. PMID:24757517

OBJECTIVE The purpose of this study was to determine whether evidence of denervation/reinnervation of the external anal sphincter is associated with anal incontinence symptoms immediately after delivery. STUDY DESIGN After a first vaginal delivery, 42 women completed an anal incontinence questionnaire. They also underwent concentric needle electromyography of the external anal sphincter. For each subject, motor unit action potential and interference pattern parameters were determined. RESULTS For the motor unit action potential, no difference was observed between patients with and without anal incontinence symptoms (t-test). For the interference pattern, the amplitude/turn was greater in subjects with fecal urgency (318 ± 48 [SD] μV) and fecal incontinence (332 ± 48 μV), compared with those without fecal urgency (282 ± 38 μV) and fecal incontinence (286 ± 41 μV; P = .02, t-test). CONCLUSION In this group of postpartum women with mild anal incontinence symptoms, interference pattern analysis shows evidence of denervation and subsequent reinnervation. PMID:18455531

Screening for Anal Cancer in HIV Positive Patients: Should We Make It A Standard-of-care?

Anal cancer is biological similar to cervical cancer, and is preceded by anal intraepithelial neoplasia (AIN). Screening for AIN and treatments to reduce the risk of anal cancer are not established as guidelines of care for HIV-infected patients. It is mainly because screening and treating of AIN is not yet proven to reduce the incidence of anal cancer. The present study preliminarily demonstrated that a successful screening program in preventing squamous cell anal cancer in HIV positive patients. The authors achieved their purpose of controlling the evolution of all abnormalities identified during the anal cancer screening, preventing AIN to progress towards anal cancer, and reversing any form of AIN by surgery, ablation or medical therapy. Randomized controlled multi-center trials with a large sample size should be carried out to validate the study results. It is wise for the physicians to actively screen and treat AIN in HIV-infected patients whenever possible unless the results of randomized controlled study demonstrate that doing so is inappropriate.

Pain is a prominent feature of acute dengue as well as a clinical criterion in World Health Organization guidelines in diagnosing dengue. We conducted a prospective cohort study to compare levels of pain during acute dengue between different ethnicities and dengue severity. Demographic, clinical and laboratory data were collected. Data on self-reported pain was collected using the 11-point Numerical Rating Scale. Generalized structural equation models were built to predict progression to severe disease. A total of 499 laboratory confirmed dengue patients were recruited in the Prospective Adult Dengue Study at Tan Tock Seng Hospital, Singapore. We found no statistically significant differences between pain score with age, gender, ethnicity or the presence of co-morbidity. Pain score was not predictive of dengue severity but highly correlated to patients' day of illness. Prevalence of abdominal pain in our cohort was 19%. There was no difference in abdominal pain score between grades of dengue severity. Dengue is a painful disease. Patients suffer more pain at the earlier phase of illness. However, pain score cannot be used to predict a patient's progression to severe disease.

OBJECTıVE: To compare the morphometric data relating to the muscular structures of the anal canal, in patients with chronic anal fissure and in control group, examined at a 3.0 Tesla MR system. Forty-seven consecutive patients with chronic anal fissure and randomly selected 40 patients who had no claims for perianal disease during their life time were included in the study. T2-weighted sagittal, high-resolution (HR) T2-weighted, and contrast-enhanced fat-suppressed T1-weighted oblique axial and oblique coronal images were retrospectively analyzed by two observers in consensus. Thickness of sphincteric muscles, anal canal length, anorectal angle, thickness of anococcygeal ligament, depth of Minor triangle, width between subcutaneous sphincters, vascularity of posterior commissure, visibility of posterosuperior projection of external sphincter, and angle between the distal anal canal and posterosuperior projection of external sphincter (H angle) in patients and in controls were compared and analyzed using t test, Mann-Whitney U test, and Spearman correlation. The patients with chronic anal fissure had longer anal canal (51.50 mm ± 0.91 vs. 44.11 mm ± 0.71; p = 0.000), thicker internal anal sphincter muscle at mid-anal level (4.18 ± 0.15 vs. 3.39 ± 0.07; p = 0.007), and wider space between subcutaneous external sphincters (11.39 ± 0.50 vs. 6.89 ± 0.22; p = 0.000). In patients, there was a positive correlation between H angle and external sphincter thickness at proximal (r = 0.347; p = 0.021), middle (r = 0427; p = 0.000), and distal (r = 0.518; p = 0.000)) levels of the anal canal. CONCLUSıON: 3.0 Tesla MR imaging provides detailed information about the morphometric changes in the anal sphincter muscles in patients with chronic anal fissure.

The diagnosis and treatment of complex anal fistula has been a significant challenge. Unwise incision and excessive exploration will lead to the secondary branch, sinus and perforation. A simple fistula may become a surgical problem and result in disastrous consequences. Preoperative accurate diagnosis of anal fistula, including in the internal opening, primary track and location of the fistula, extensions and abscess, is important for anal fistula treatment. In the diagnosis of anal fistula, imaging examination, especially MRI plays a crucial role. Localization and demarcation of anal fistula and the relationship with sphincter are important. MRI has been an indispensable confirmatory imaging examination.

Anal sex is an important yet little studied HIV risk behavior for women. Using information collected on recent sexual encounters, we examined the influence of sex partner and relationship characteristics on the likelihood of engaging in anal sex among women with a high risk of HIV infection. Anal sex was nearly 3 times more common among actively bisexual women (OR = 2.96, 95% CI: 2.17-4.03). Women were more likely to have anal sex with partners who injected drugs (OR = 2.32, 95% CI: 1.44-3.75), were not heterosexual (OR = 1.85, 95% CI: 1.18-2.90), and with whom they exchanged money or drugs for sex (OR = 1.79, 95% CI: 1.10-2.90). The likelihood of anal sex also increased with the number of nights sleeping together (OR = 1.15, 95% CI: 1.06-1.24). In contrast, emotional closeness and social closeness were not associated with anal sex. Condom use during anal sex was uncommon, and did not vary according to partner or relationship characteristics. Our findings support the need for HIV prevention interventions that target anal sex among heterosexuals, particularly in drug-using populations residing in neighborhoods with elevated levels of HIV prevalence.

Introduction The incidence of anal cancer is significantly higher in men who have sex with men (MSM) living with HIV when compared to the general population. We aimed to assess their awareness, knowledge and perceived level of personal risk for anal cancer to help inform educational strategies targeting this group. Methods A cross-sectional study of 327 HIV positive MSM in Melbourne, Australia, attending clinical settings (a sexual health centre, tertiary hospital HIV outpatients and high HIV caseload general practices) completed a written questionnaire in 2013/14. Poor knowledge was defined as those who had never heard of anal cancer, or scored 5 or less out of 10 in knowledge questions amongst those who reported ever hearing about anal cancer. Underestimation of risk was defined as considering themselves as having the same or lower risk for anal cancer compared to the general population. Results Of 72% (95% confidence interval (CI): 67–77) who had heard of anal cancer, 47% (95% CI: 41–53) could not identify any risk factors for anal cancer. Of total men surveyed, 51% (95% CI: 46–57) underestimated their risk for anal cancer. Multivariate analysis showed that men who underestimated their risk were older (OR 1.04 (per year increase in age), 95% CI: 1.01–1.07), had poor anal cancer knowledge (OR 2.06, 95% CI: 1.21–3.51), and more likely to have ever had an anal examination (OR 2.41, 95% CI: 1.18–4.93). They were less likely to consult a physician if they had an anal abnormality (OR 0.54, 95% CI: 0.31–0.96), to have had receptive anal sex (OR 0.12, 95% CI: 0.02–0.59) or speak English at home (OR 0.28, 95% CI: 0.09–0.90). Conclusions This survey of MSM living with HIV demonstrated limited awareness, knowledge level and estimation of risk for anal cancer. Further educational and public health initiatives are urgently needed to improve knowledge and understanding of anal cancer risk in MSM living with HIV. PMID:25828269

Women's experiences with anal sex: motivations and implications for STD prevention.

Heterosexual anal intercourse is a highly efficient mode of HIV transmission, yet little is known about the contexts in which women engage in it, or when and with whom they use condoms. Similarly, sexuality and reproductive health research has paid little attention to female desire and pleasure-seeking. In-depth interviews were conducted in Boston in 2006 with 28 women who reported having had unprotected anal intercourse in the last year with a man who was HIV-positive or whose serostatus was unknown. Sexual scripting theory guided analyses of their experiences with and motivations to practice anal intercourse. Participants engaged in anal intercourse for a wide variety of reasons: to experience physical pleasure, enhance emotional intimacy, please their male partners or avoid violence. Male partners usually initiated anal sex. Anal intercourse often occurred in the context of vaginal and oral sex. Among reasons women cited for not using condoms were familiarity with their partner and feeling that condoms made anal sex less pleasurable. Knowledge of HIV and STD risks did not appear to encourage condom use. Women who perceive condom use during anal sex as limiting their pleasure or intimacy may be at increased risk for acquiring HIV. Consequently, interventions to promote safer anal intercourse must find a way to increase the use of barrier methods without decreasing pleasure or perceived intimacy between sexual partners.

2015-01-01

The aim of this review is to provide an overview of the use of biological materials in the augmentation of the anal sphincter either as part of an overlapping sphincter repair (OSR) or anal bulking procedure. A systematic search of PubMed was conducted using the search terms "anal bulking agents," "anal sphincter repair," or "overlapping sphincter repair." Five studies using biological material as part of an overlapping sphincter repair (OSR) or as an anal bulking agent were identified. 122 patients underwent anal bulking with a biological material. Anorectal physiology was conducted in 27 patients and demonstrated deterioration in maximum resting pressure, and no significant change in maximum squeeze increment. Quality of life scores (QoLs) demonstrated improvements at 6 weeks and 6 months, but this had deteriorated at 12 months of follow up. Biological material was used in 23 patients to carry out an anal encirclement procedure. Improvements in QoLs were observed in patients undergoing OSR as well as anal encirclement using biological material. Incontinence episodes decreased to an average of one per week from 8 to 10 preoperatively. Sphincter encirclement with biological material has demonstrated improvements in continence and QoLs in the short term compared to traditional repair alone. Long-term studies are necessary to determine if this effect is sustained. As an anal bulking agent the benefits are short-term.

Pain and sleep disturbances are widespread, and are an important cause of a reduced quality of life. Despite this, there is a paucity of multinational population data assessing the association between pain and sleep problems, particularly among low- and middle-income countries (LMICs). Therefore, we investigated the relationship between pain and severe sleep disturbance across 45 LMICs. Community-based data on 240,820 people recruited via the World Health Survey were analyzed. Multivariable logistic regression analyses adjusted for multiple confounders were performed to quantify the association between pain and severe sleep problems in the last 30 days. A mediation analysis was conducted to explore potential mediators of the relationship between pain and severe sleep disturbance. The prevalence of mild, moderate, severe, and extreme levels of pain was 26.0%, 16.2%, 9.1%, and 2.2% respectively, whilst 7.8% of adults had severe sleep problems. Compared to those with no pain, the odds ratio (OR, 95% CI) for severe sleep problems was 3.65 (3.24-4.11), 9.35 (8.19-10.67) and 16.84 (13.91-20.39) for those with moderate, severe and extreme pain levels respectively. A country wide meta-analysis adjusted for age and sex demonstrated a significant increased OR across all 45 countries. Anxiety, depression and stress sensitivity explained 12.9%, 3.6%, and 5.2%, respectively, of the relationship between pain and severe sleep disturbances. Pain and sleep problems are highly co-morbid across LMICs. Future research is required to better understand this relationship. Moreover, future interventions are required to prevent and manage the pain and sleep disturbance comorbidity. Copyright © 2018 Elsevier Inc. All rights reserved.

Background Although foot pain has been linked to fall risk, contributions of pain severity, foot posture or foot function are unclear. These factors were examined in a cohort of older adults. Objective The purpose of this study was to examine the associations of foot pain, severity of foot pain and measures of foot posture and dynamic foot function with reported falls in a large, well-described cohort of older adults from the Framingham Foot Study. Methods Foot pain, posture and function were collected from Framingham Foot Study participants who were queried about falls over the past year (0, 1, 2+ falls). Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for the relation of falls with foot pain, pain severity, foot posture, and foot function adjusting for covariates. Results Of 1375 participants, mean age was 69y; 57% were female; 21% reported foot pain (40% mild pain, 47% moderate, 13% severe pain). One-third reported falls in past year (1 fall: n=263, 2+ falls: n=152). Foot pain was associated with a 62% increased odds of recurrent falls. Those with moderate and severe foot pain showed increased odds of 2+ falls (OR=1.78, CI 1.06–2.99, and OR = 3.25, CI 1.65–7.48, respectively) compared to no foot pain. Foot function was not associated with falls. Compared to normal foot posture, those with planus foot posture had 78% higher odds of 2+ falls. Conclusion Higher odds of recurrent falls were observed in individuals with foot pain, especially severe foot pain, as well as individuals with planus foot posture, indicating that both foot pain and foot posture may play a role in increasing the risk of falls among older adults.

Anal cancer is relatively common amongst HIV positive men who have sex with men (MSM), but little is known about the anal cancer screening practices of HIV physicians, and whether digital ano-rectal examination (DARE) is utilized for this. To determine the practice of anal cancer screening among HIV physicians, and to identify any barriers for implementing DARE as a method for anal cancer screening. 36 physicians from a sexual health centre, 2 tertiary hospital infectious diseases outpatient clinics, and 2 general practices completed a questionnaire on their practice of anal cancer screening amongst HIV positive MSM. Physicians were asked about their confidence in using DARE for anal cancer screening, and whether they perceived barriers to implementing this in their clinic. Most physicians (86%, 95% CI: 71-95) thought that anal cancer screening was important, but only 22% (95% CI: 10-39) were currently screening. Reasons for not screening were the absence of guidelines (87%, 95% CI: 60-98), lack of time (47%, 95% CI: 30-65), and concern about patient acceptability of DARE (32%, 95% CI: 17-51). Whilst 67% (95% CI: 49-81) of physicians felt confident in performing a DARE, only 22% (95% CI: 10-39) were confident in recognizing anal cancer using DARE. Although HIV physicians were aware of the need for anal cancer screening among the HIV + MSM population, few were routinely screening. If DARE were to be incorporated into routine HIV care, guidelines recommending screening and up-skilling of HIV physicians to recognize anal cancer are needed.

The anal sex among heterosexual couples is on the rise as reported in many scientific studies. Considering that unprotected anal sex has higher risk of human immunodeficiency virus (HIV) transmission than the vaginal sex, we undertook a study to understand the anal sex practices among Female Sex Workers (FSW). The study was conducted among FSW attending 11 randomly selected sexually transmitted infection (STI) clinics in Bill and Melinda Gates supported targeted interventions in Andhra Pradesh. A structured questionnaire was administered to the 555 FSW attending these clinics by project clinic counselors. Informed consent was obtained from all the study participants. Engaging in anal sex was self reported by 22% of sex workers, though demand from clients was reported to be much higher (40%). The reasons for anal sex practices included more money (61%), clout/influence of the client (45%), risk of losing client (27%), and forced sex (1.2%). Factors associated with anal sex were higher number of clients, higher duration of sex work, higher income, and older age group. Associated risks perceived by FSW were bleeding and injury to anal canal (98%) while only 28% associated it with higher HIV transmission risk. Reported Condom and lubricant use was about 88% and 39% respectively. The study shows that there is frequent anal sex, inconsistent condom and infrequent lubricant usage, economic and physical coercion, and low awareness of STI/HIV transmission risk among FSW, which have serious implications for HIV prevention programmes. There is a need to focus on anal sex education and use of lubricants along with condoms during anal sex in FSW-targeted interventions in AP.

Anal fissure has a very large number of treatment options. The choice is difficult. In an effort to assist in that, choice presented here is a systematic review and meta-analysis of all published treatments for anal fissure that have been studied in randomized controlled trials. Randomized trials were sought in the Cochrane Controlled Trials Register, Medline, EMBASE and the trials registry sites clinicaltrials.gov and who/int/ictrp/search/en. Abstracts were screened, full-text studies chosen, and finally eligible studies selected and abstracted. The review was then divided into those studies that compared two or more surgical procedures and those that had at least one arm that was non-surgical. Studies were further categorized by the specific interventions and comparisons. The outcome assessed was treatment failure. Negative effects of treatment assessed were headache and anal incontinence. Risk of bias was assessed for each study, and the strength of the evidence of each comparison was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. One hundred and forty-eight eligible trials were found and assessed, 31 in the surgical group and 117 in the non-surgical group. There were 14 different operations described in the surgical group and 29 different non-surgical treatments in the non-surgical group along with partial lateral internal sphincterotomy (LIS). There were 61 different comparisons. Of these, 47 were reported in 2 or fewer studies, usually with quite small patient samples. The largest single comparison was glyceryl trinitrate (GTN) versus control with 19 studies. GTN was more effective than control in sustained cure (OR 0.68; 95% CI 0.63-0.77), but the quality of evidence was very poor because of severe heterogeneity, and risk of bias due to inadequate clinical follow-up. The only comparison to have a GRADE quality of evidence of high was a subgroup analysis of LIS versus any medical therapy (OR 0.12; CI 0.07-0.21). Most of the other studies were downgraded in GRADE due to imprecision. LIS is superior to non-surgical therapies in achieving sustained cure of fissure. Calcium channel blockers were more effective than GTN and with less risk of headache, but with only a low quality of evidence. Anal incontinence, once thought to be a frequent risk with LIS, was found in various subgroups in this review to have a risk between 3.4 and 4.4%. Among the surgical studies, manual anal stretch performed worse than LIS in the treatment of chronic anal fissure in adults. For those patients requiring surgery for anal fissure, open LIS and closed LIS appear to be equally efficacious, with a moderate GRADE quality of evidence. All other GRADE evaluations of procedures were low to very low due mostly to imprecision.

The objective of this study was to assess the effect of clinical depression on pain self-management practices. We employed a cross-sectional analysis of baseline data from the Stepped Care for Affective disorders and Musculoskeletal Pain (SCAMP) study. Participants included 250 patients with pain and comorbid depression and 250 patients with pain only and were enrolled from urban university and VA primary care clinics. Musculoskeletal pain was defined as low back, hip or knee pain present >or=3 months and with at least a moderate, Brief Pain Inventory severity score >or=5. Depression was defined as a PHQ-9 score >or=10. We used multiple logistic and Poisson regression to assess the relationship between individual and combined effects of depression and pain severity on two core pain self-management skills: exercise duration and cognitive strategies. Depressed patients exercised less per week than did nondepressed patients but showed a trend towards more frequent use of cognitive strategies. On multivariable analysis, depression severity substantially decreased the use of exercise as a pain self-management strategy. In contrast, depression and pain severity interacted to increase the use of cognitive strategies. Depression and pain severity have differential effects on self-management practices. Understanding the differences between preferential strategies of pain patients with and without depression may be useful in tailoring pain self-management programs.

This qualitative study investigates the different methods for selecting sex partners by Korean homosexuals considering factors related to homosexual identity and sexual behavior. We take the approach of the grounded theory to examine the issue of sexual partnering of men who have sex with men (MSM). In-depth interviews of urban MSM and bisexual men were conducted. The snowball sampled through a MSM portal web site. Three key informants from the several areas were collected through a MSM portal website, and then, participants were gradually recruited with the snowball samplings in South Korea, 2011 (n=32). The results of coding the interviews based on the grounded theory approach identified three types of partnering: 1) MSM who do not prefer anal intercourse, but pursue safe sex in long-term relationships with fixed partners; 2) those who have fixed partners and perform anal sex, a category into which both MSM and bisexuals fall; and 3) those engaged in anal sex, but enjoy a concurrent sexual relationship without having fixed partners, which was common among bisexuals. The findings from this study elucidate several MSM and bisexual partnering types practice safe sex. This diversity in MSM partnering may increase the vulnerability of some MSM to HIV infection as safe-sex practices remain a matter of individual choice. Changes in Korean societal policies are necessary to enhance capacity building and encourage the practice of safe sex at the community level.

Teaching Men's Anal Pleasure: Challenging Gender Norms with "Prostage" Education

To help students critique sex/gender norms, sexuality educators should address men's anal pleasure. Men's anal receptivity blurs accepted binaries like male/female, masculine/feminine, and straight/queer. By suppressing men's receptivity, the taboo against men's anal pleasure helps legitimize hegemonic sex/gender beliefs--and the sexism,…

Pain symptoms in Malay patients with major depression.

2012-12-01

There is a strong association between depression and pain, which is influenced by various biological and psychological mechanisms. The objectives of this study were to assess the prevalence and severity of pain symptoms among patients with major depression; and to determine the correlation between pain with clinical variables, neurotic pathology and severity of depression. Fifty-one Malay patients with major depressive disorder without psychotic feature enrolled for the study. They were assessed with the Hamilton Rating Scale for Depression (HAM-D), Brief Pain Inventory (BPI) and Crown Crisp Experiential Index (CCEI). The majority (80.4%) of the subjects had experienced pain, but overall severity of the pain was mild (33.3%). There were no statistically significant differences in socio-demographic variables with the status of pain. The prevalence of pain was significantly higher in patients who were still depressed (p<0.05), had anxious depression (p<0.05) and those with prominent somatic symptoms of anxiety (SOM) (p<0.05). The severity of pain was significantly correlated with neuroticism, the severity of depression (HAM-D total score) and high scores on SOM, DEP and FFA subscales of the CCEI. Among the three, the DEP subscale had the highest correlation with severity of pain. The somatising patients were heterogeneous group. The pain symptoms were common in severe mixed anxiety-depression, predisposed by the underlying neurotic pathology. Neuroticism and high scores on SOM, DEP and FFA subscales of the CCEI contributed significantly to the pathogenesis of depressed Malay patients with pain symptoms. Copyright © 2012 Elsevier B.V.

2018-02-01

Objective measures of pain severity remain ill defined, although its accurate measurement is critical. Reciprocal baroreflex mechanisms of blood pressure (BP) control were found to impact differently on pain regulation, and thus their asymmetry was hypothesized to also connect to chronic pain duration and severity. Seventy-eight female patients with irritable bowel syndrome (IBS) and 27 healthy women were assessed for IBS severity and chronicity, negative affect, and various measures of resting autonomic function including BP, heart rate and its variability (HRV), baroreceptor-sensitivity to activations and inhibitions, gains of brady- and tachy-cardiac baro-responses, gains of BP falls/rises, and BP start points for these spontaneous baroreflexes. IBS directly and indirectly (through increased negative affect) was associated with asymmetry between baroreceptor activations/inhibitions compared to symmetrical baroreflex reciprocity in the healthy women. In the IBS group, independently of specific IBS symptoms, pain chronicity was associated with (i) decreased BP falls coupled with either (a) decreased tachycardia associated with lower disease severity (earlier "pain resilience" mechanism), or (b) decreased bradycardia associated with higher disease severity (later "pain decompensation" mechanism), or (ii) increased BP start point for baroreceptor activations coupled with either (a) BP increase (delayed "pain adaptation" mechanism) or (b) affect-related HRV decrease (delayed "pain aggravation" mechanism). We anticipate the findings to be a starting point for validating these autonomic metrics of pain suffering and pain coping mechanisms in other chronic pain syndromes to suggest them as biomarkers of its severity and duration for profiling and correct management of chronic pain patients. © 2017 John Wiley & Sons Ltd.

Associations between pain and depression are well known, yet foot pain, common in populations, has been understudied. This cross-sectional study examined foot pain and severity of foot pain with depressive symptoms in adults. Framingham Foot Study (2002-2008) participants completed questionnaires that included questions about foot pain (yes/no; none, mild, moderate, or severe pain) and the Center for Epidemiologic Studies Depression Scale (scores ≥16 indicated depressive symptoms). Age and body mass index (BMI) were also assessed. Sex-specific logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) for associations of foot pain with depressive symptoms, adjusting for age and BMI. In a subset, further models adjusted for leg pain, back pain, or other joint pain. Of 1,464 men and 1,857 women, the mean ± SD age was 66 ± 10 years. Depressive symptoms were reported in 21% of men and 27% of women. Compared to those with no foot pain and independent of age and BMI, both men and women with moderate foot pain had approximately a 2-fold increased odds of depressive symptoms (men with severe foot pain OR of 4 [95% CI 2.26-8.48], women with severe foot pain OR of 3 [95% CI 2.02-4.68]). Considering other pain regions attenuated ORs, but the pattern of results remained unchanged. Even after we adjusted for age, BMI, and other regions of pain, those reporting worse foot pain were more likely to report depressive symptoms. These findings suggest that foot pain may be a part of a broader pain spectrum, with an impact beyond localized pain and discomfort. © 2016, American College of Rheumatology.

Parental pain catastrophizing is a construct recognized to have a significant impact on experience of pain in both children and parents. This research aimed to investigate the probable relationship of parental pain catastrophizing with the parent's reports of children's anxiety, depression and headache severity amongst Iranian parents of children with chronic or recurrent headache. This study was conducted in 2015-16, in two pediatric neurological centers located in Tehran, Iran; with a convenience sampling method and 212 parents (120 mothers and 92 fathers) of 132 children with a chronic or recurrent headache (migraine and tension-type). They completed the Pain Catastrophizing Scale; Numeric Pain Rating Scale, asking for the average of pain severity in last three months before the research, and the Anxiety and Depression subscales of the Children Behavioral Check List. The mean age of parents was 35.41 yr (SD=5.58) and the mean age of children was 9.83 yr (SD=2.77). A total of 72 girls and 60 boys participated in this study with a mean pain severity for headache in last three months before the research of 4.99 (SD=2.63). Probable sex differences according to parental pain catastrophizing, pain severity, anxiety, and depression were assessed amongst parents. In the next step, the predictability of pain severity from parental pain catastrophizing was evaluated. Results indicated a significant relationship in maternal pain catastrophizing and estimates of pain intensity by mothers. These findings represent the importance of parent's especially mother's cognitive factors affecting their reports of their children's pain and related emotional disturbances.

We analized the long-term results after surgical treatment in 41 patients with chronic pancreatitis. Twenty one of them underwent resection: 19 pancreaticoduodenectomy (11 Whipple procedure and 8 Traverso Longmire); total pancreatectomy (1) and near-total pancreatectomy (1). In the remaining 20 patients a drainage procedure was carried out: Puestow-Duval (5); Partington (7); double derivation: pancreatic and biliar (5); triple derivation: pancreatic, biliar, gastric (2) and Nardi procedure+quisteduodenostomy in one patient. The following were evaluated: persistent pain; chronic alcoholism; nutrition status; exocrine function (syntomatic steatorrea, use of pancreatic enzyme preparation and fecal determination of glucide, protids and lipids) and endocrine function (glucose and insulin levels and glucose oral test). Surgery failed to relieve pain in 15.6% of the patients; failures were associated chronic alcoholism (p < 0.05); 18 patients (44%) required oral pancreatic enzymes. There weren't significant differences between resection and drainage procedures regarding the exocrine function. However, endocrine function was significantly worse (p < 0.05) after pancreaticoduodenectomy than after drainages procedures. Among the late, the endocrine function was better after Partington operation than after the Puestow-Duval.

Rectoanal repair (RAR), which combines doppler-guided hemorrhoidal artery ligation (HAL) and mucopexy via lifting of the hemorrhoidal prolapse, offers a minimally invasive alternative to conventional hemorrhoidectomy. Patients with grade II hemorrhoids were treated with HAL, and patients with grade III and IV hemorrhoids were treated with the RAR procedure by two surgeons. Postoperative follow-up was performed clinically and by proctoscopy after 8 weeks routinely, and long-term follow-up was performed using a standardized postal questionnaire. The overall complication rate was 29% (n = 118). After short-term follow-up, 26% (n = 106) of patients reported recurrent or persistent prolapsing piles, while 21% (n = 86) of patients had recurrent bleeding. After long-term follow-up, 24% (n = 98) of patients reported prolapsing piles, 3% (n = 12) bleeding, 3% (n = 12) pruritus, and 2% (n = 8) anal pain, while 20% (n = 82) complained of persistent mixed symptoms. HAL and RAR provide prolonged relief for patients with hemorrhoidal disease whose main symptoms are bleeding, pruritus and pain but not for patients with prolapse as an initial indication.

Effective treatment of dyssynergic defecation using sacral neuromodulation in a patient with cerebral palsy.

PubMed

Chan, Daniel K; Barker, Matthew A

2015-01-01

Dyssynergic defecation is a complex bowel problem that leads to chronic constipation and abdominal pain. Management is often challenging owing to the incoordination of multiple pelvic floor muscles involved in normal defecation. We report a case of dyssynergic defecatory dysfunction in a patient with cerebral palsy treated with sacral neuromodulation. At presentation, Sitz marker study and magnetic resonance defecography showed evidence of chronic functional constipation. Anorectal manometry, rectal anal inhibitory reflex, and rectal sensation study showed intact reflex and decreased first sensation of lower canal at 50 mL. After stage 2 of InterStim implant placement, bowel habits improved to once- to twice-daily soft solid bowel movements from no regular solid bowel movements. Fecal incontinence improved from daily liquid and small solid loss to no stool leakage. In patients with systemic medical problems contributing to defecatory dysfunction and bowel incontinence, such as cerebral palsy, sacral neuromodulation was found to provide significant relief of bowel symptoms in addition to associated abdominal pain. As a result of intervention, the patient reported significant improvement in quality of life and less limitations due to dyssynergic defecation.

A 4-year-old female Siberian Husky was diagnosed with pyogranulomatous steatitis at the site of a recurrence of left anal sac rupture (day 1). Carprofen and orbifloxacin were given for 13 days without improvement. A single dose of meloxicam was administered prior to surgical resection of the anal sac, and based on elevated liver enzyme activity, liver supportive therapy was initiated. The dog received carprofen and orbifloxacin orally on the evening of day 14. The dog became anorectic the following morning, and began vomiting. Despite supportive therapy, the dog was unresponsive to treatment and died on day 16. Postmortem examination revealed severe vacuolar change and acute necrosis of hepatocytes consistent with carprofen and meloxicam induced-toxicosis.

We conducted a qualitative study to examine the impact of an HIV prevention programme on female sex workers' lives in Guntur district, Andhra Pradesh. The study found evidence that, in addition to the HIV prevention programme, structural and environmental factors had recently changed the way sex work was being practiced. Recent closure of the brothels and implementation of a late-night street curfew by the police meant sex work had become more hidden, with clients often solicited using mobile phones from home or their work place (e.g., in the fields or factories). Sex work had become safer, with violence by non-regular partners rarely reported. Women understood the risks of unprotected vaginal sex and reported using condoms with their clients. However, clients were more frequently requesting anal sex, possibly due to recent exposure to pornography following increased accessibility to modern technologies such as mobile phones and the Internet. Anal sex with clients was common but women were often unaware of the associated risks and reported unprotected anal sex. HIV positive and/or older women faced severe financial hardship and difficulty soliciting sufficient clients, and reported unprotected vaginal and anal sex to earn enough to survive. Taken together, the findings from this study suggest changing vulnerability to HIV in this setting. It will be important for HIV prevention programmes to be flexible and creative in their approaches if they are to continue to reach this target community effectively.

Carcinoma of the anal canal: Intensity modulated radiation therapy (IMRT) versus three-dimensional conformal radiation therapy (3DCRT).

Patients with anal canal carcinoma treated with standard conformal radiotherapy frequently experience severe acute and late toxicity reactions to the treatment area. Roohipour et al. (Dis Colon Rectum 2008; 51: 147-53) stated a patient's tolerance of chemoradiation to be an important prediction of treatment success. A new intensity modulated radiation therapy (IMRT) technique for anal carcinoma cases has been developed at the Andrew Love Cancer Centre aimed at reducing radiation to surrounding healthy tissue. A same-subject repeated measures design was used for this study, where five anal carcinoma cases at the Andrew Love Cancer Centre were selected. Conformal and IMRT plans were generated and dosimetric evaluations were performed. Each plan was prescribed a total of 54 Gray (Gy) over a course of 30 fractions to the primary site. The IMRT plans resulted in improved dosimetry to the planning target volume (PTV) and reduction in radiation to the critical structures (bladder, external genitalia and femoral heads). Statistically there was no difference between the IMRT and conformal plans in the dose to the small and large bowel; however, the bowel IMRT dose-volume histogram (DVH) doses were consistently lower. The IMRT plans were superior to the conformal plans with improved dose conformity and reduced radiation to the surrounding healthy tissue. Anecdotally it was found that patients tolerated the IMRT treatment better than the three-dimensional (3D) conformal radiation therapy. This study describes and compares the planning techniques.

Human papillomaviruses (HPVs) cause cancer at multiple anatomic sites in men and women, including cervical, oropharyngeal, anal, vulvar, and vaginal cancers in women and oropharyngeal, anal, and penile cancers in men. In this EUROGIN 2014 roadmap, differences in HPV-related cancer and infection burden by gender and anatomic site are reviewed. The proportion of cancers attributable to HPV varies by anatomic site, with nearly 100% of cervical, 88% of anal, and less than 50% of lower genital tract and oropharyngeal cancers attributable to HPV, depending on world region and prevalence of tobacco use. Often mirroring cancer incidence rates, HPV prevalence and infection natural history varies by gender and anatomic site of infection. Oral HPV infection is rare and significantly differs by gender; yet HPV-related cancer incidence at this site is several-fold higher than at either the anal canal or penile epithelium. HPV seroprevalence is significantly higher among women compared to men, likely explaining the differences in age-specific HPV prevalence and incidence patterns observed by gender. Correspondingly, among heterosexual partners, HPV transmission appears higher from women to men. More research is needed to characterize HPV natural history at each anatomic site where HPV causes cancer in men and women, information that is critical to inform the basic science of HPV natural history and the development of future infection and cancer prevention efforts.

Obstetric anal sphincter injury (OASIS) following vaginal delivery increases the risk of anal incontinence (AI). Subsequent vaginal delivery and ageing increase the risk of worsening symptoms. Very little literature describes any in-depth understanding of what it is like to live with AI following a history of known OASIS. To describe and interpret women's experience of AI following OASIS and its impact on quality of life. An interpretive phenomenological study was conducted in a level 2 tertiary hospital in South Australia. Women with a history of OASIS and AI were purposefully recruited. The St Marks Vaizey score was utilised to identify symptom severity. Semi-structured open-ended interviews were conducted, and data were analysed utilising Van Manen thematic analysis. Participants (n = 10) aged 26-56 years. All women were symptomatic of AI following OASIS, and 80% had received a primary OASIS at their first vaginal delivery. The St Marks Vaizey score mean was 9.1 (range within 4-22). Three essential themes grieving for loss, silence, striving for normality with eight subthemes identified a significant sense of loss and psychological impact of AI for this group of women. Health professionals require a greater understanding of the negative impact of OASIS and AI on women's quality of life. This may improve the management, education and clinical care of this condition which may result as a consequence of OASIS. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Less is known about the sexual health of young adults than about adolescents, despite 20 to 24-year-olds' greater risk of unintended pregnancy and sexually transmissible infections. This paper provides information on college students' prior and current sexual practices including oral sex, vaginal intercourse, anal intercourse and masturbation. We analysed data from a cross-sectional sexuality survey of students from two university campuses in the USA, one Mid-western and one South-western (n = 1504). The sample consisted of non-Hispanic white, never-married students who identified as heterosexual. Of 16 possible combinations of four sexual activities (solitary masturbation, oral sex, vaginal intercourse and anal intercourse), only four contained more than 5% of respondents: masturbation, oral sex and vaginal intercourse (37%); oral sex and vaginal intercourse only (20%); all four (14%); and none (8%). Twenty percent had ever engaged in anal intercourse. Women were significantly less likely than men to have ever masturbated (48 v. 92%). Analyses exhibited several sexual health challenges, including lack of verbal sexual consent, alcohol use proximal to sex and lack of contraceptive use. Although few young adults are substituting it for vaginal intercourse, anal intercourse is increasingly common and safer sex efforts should encourage condom use during both sexual activities. Masturbation should be encouraged as an alternative to higher risk sexual practices and an essential aspect of sexual well being. Finally, practitioners should continue to address specific threats to college students' sexual health, including alcohol use and non-verbal consent.

Human papillomaviruses (HPVs) cause cancer at multiple anatomic sites in men and women, including cervical, oropharyngeal, anal, vulvar and vaginal cancers in women and oropharyngeal, anal and penile cancers in men. In this EUROGIN 2014 roadmap, differences in HPV-related cancer and infection burden by gender and anatomic site are reviewed. The proportion of cancers attributable to HPV varies by anatomic site, with nearly 100% of cervical, 88% of anal and <50% of lower genital tract and oropharyngeal cancers attributable to HPV, depending on world region and prevalence of tobacco use. Often, mirroring cancer incidence rates, HPV prevalence and infection natural history varies by gender and anatomic site of infection. Oral HPV infection is rare and significantly differs by gender; yet, HPV-related cancer incidence at this site is several-fold higher than at either the anal canal or the penile epithelium. HPV seroprevalence is significantly higher among women compared to men, likely explaining the differences in age-specific HPV prevalence and incidence patterns observed by gender. Correspondingly, among heterosexual partners, HPV transmission appears higher from women to men. More research is needed to characterize HPV natural history at each anatomic site where HPV causes cancer in men and women, information that is critical to inform the basic science of HPV natural history and the development of future infection and cancer prevention efforts. © 2014 UICC.

Carcinoma of the anal canal: Intensity modulated radiation therapy (IMRT) versus three-dimensional conformal radiation therapy (3DCRT)

Sale, Charlotte; Moloney, Phillip; Mathlum, Maitham

Patients with anal canal carcinoma treated with standard conformal radiotherapy frequently experience severe acute and late toxicity reactions to the treatment area. Roohipour et al. (Dis Colon Rectum 2008; 51: 147–53) stated a patient's tolerance of chemoradiation to be an important prediction of treatment success. A new intensity modulated radiation therapy (IMRT) technique for anal carcinoma cases has been developed at the Andrew Love Cancer Centre aimed at reducing radiation to surrounding healthy tissue. A same-subject repeated measures design was used for this study, where five anal carcinoma cases at the Andrew Love Cancer Centre were selected. Conformal and IMRTmore » plans were generated and dosimetric evaluations were performed. Each plan was prescribed a total of 54 Gray (Gy) over a course of 30 fractions to the primary site. The IMRT plans resulted in improved dosimetry to the planning target volume (PTV) and reduction in radiation to the critical structures (bladder, external genitalia and femoral heads). Statistically there was no difference between the IMRT and conformal plans in the dose to the small and large bowel; however, the bowel IMRT dose–volume histogram (DVH) doses were consistently lower. The IMRT plans were superior to the conformal plans with improved dose conformity and reduced radiation to the surrounding healthy tissue. Anecdotally it was found that patients tolerated the IMRT treatment better than the three-dimensional (3D) conformal radiation therapy.

Sex role segregation and mixing among men who have sex with men: implications for biomedical HIV prevention interventions.

PubMed

Armbruster, Benjamin; Roy, Sourya; Kapur, Abhinav; Schneider, John A

2013-01-01

Men who have sex with men (MSM) practice role segregation - insertive or receptive only sex positions instead of a versatile role - in several international settings where candidate biomedical HIV prevention interventions (e.g., circumcision, anal microbicide) will be tested. The effects of these position-specific interventions on HIV incidence are modeled. We developed a deterministic compartmental model to predict HIV incidence among Indian MSM using data from 2003-2010. The model's sex mixing matrix was derived from network data of Indian MSM (n=4604). Our model captures changing distribution of sex roles over time. We modeled microbicide and circumcision efficacy on trials with heterosexuals. Increasing numbers of versatile MSM resulted in little change in HIV incidence over 20 years. Anal microbicides and circumcision would decrease the HIV prevalence at 10 years from 15.6% to 12.9% and 12.7% respectively. Anal microbicides would provide similar protection to circumcision at the population level despite lower modeled efficacy (54% and 60% risk reduction, respectively). Combination of the interventions were additive: in 5 years, the reduction in HIV prevalence of the combination (-3.2%) is almost the sum of their individual reductions in HIV prevalence (-1.8% and -1.7%). MSM sex role segregation and mixing, unlike changes in the sex role distribution, may be important for evaluating HIV prevention interventions in international settings. Synergies between some position-specific prevention interventions such as circumcision and anal microbicides warrant further study.

. A pilot study on pain assessment among elderly with severe dementia in residential aged care facilities of Reggio Emilia district. Despite the availability of pain assessment tools and best practice recommendations for the assessment and management of pain in people with severe dementia, pain in residential aged care facilities is still undetected or misinterpreted. To assess pain prevalence and analgesic load medication in people with severe cognitive impairment admitted to residential aged care facilities of Reggio Emilia (Italy) province. A pilot cross-sectional study was conducted on 84 elderly patients affected by severe dementia and resident in aged care facilities. Pain was assessed with the PAINAD observational scale, both at rest and during routine procedures: positioning in bed, from bed to standing position, from bed to chair or during the medication of a pressure sore (under challenge). 33.4% of patients had pain at rest, mainly mild, and 86.9 % under challenge. During routine interventions, in 64 patients (76.2%) pain increased compared to at rest condition (for 39, 2/3, moderate-severe); although 46 of them were prescribed as-required analgesic medication, none had received the drug. Also patients with analgesics on regular basis experienced more pain during routine procedures. Many patients experienced pain during routine procedures. The regular use of pain assessment tools and adequate training of all healthcare professionals are essential requirements for an effective pain control.

Sleep disturbance in chronic pain is common, occurring in two-thirds of patients. There is a complex relationship between chronic pain and sleep; pain can disrupt sleep and poor sleep can exaggerate pain intensity. This may have an impact on both depressive symptoms and attention to pain. This study aims to evaluate the relationship between chronic pain and sleep, and the role of mood and attention. Chronic pain patients, recruited from a secondary care outpatient clinic, completed self-report measures of pain, sleep, depressive symptoms and attention to pain. Hierarchical regression and structural equation modelling were used to explore the relationships between these measures. Participants (n = 221) were aged between 20 and 84 (mean = 52) years. The majority of participants were found to be 'poor sleepers' (86%) with increased pain severity, depressive symptoms and attention to pain. Both analytical approaches indicated that sleep disturbance is indirectly associated with increased pain severity Instead the relationship shared by sleep disturbance and pain severity was further associated with depressive symptoms and attention to pain. Our results indicate that sleep disturbance may contribute to clinical pain severity indirectly though changes in mood and attention. Prospective studies exploring lagged associations between these constructs could have critical information relevant to the treatment of chronic pain.

Stained cytological specimens from 7 canine anal sac gland adenomas and 11 canine anal sac gland carcinomas were analyzed by computer-assisted nuclear morphometry. In each case, the nuclei of at least 100 neoplastic cells were measured, and the mean nuclear area (MNA), mean nuclear perimeter (MNP), mean nuclear diameter (MND) and nuclear roundness (NR) were calculated. The study aimed to evaluate (1) the possibility of using nuclear cytomorphometry as an auxiliary diagnostic method to differentiate between canine anal sac gland adenomas and adenocarcinomas, and (2) the prognostic value of nuclear morphometry in canine anal sac gland adenocarcinomas. The results indicated that (1) MNA, MNP, MND and NR could be used as effective auxiliary tools for differential diagnosis between canine anal sac gland adenomas and adenocarcinomas, and (2) MNA, MNP and MND are reliable prognostic indicators for canine anal sac gland adenocarcinomas.

SYNOPSIS Anal cancer is an increasingly common non-AIDS-defining cancer among HIV-infected individuals. It is associated with human papillomavirus (HPV), the most common sexually transmitted infectious agent. The 14 oncogenic types of HPV are causally associated with 5–10% of all cancers, notably anogenital cancers. HPV16 is the most common genotype detected in about 70% of anal cancers. The HPV types detected in anal cancer are included in the 9-valent vaccine. HPV vaccines have demonstrated efficacy in reducing anal precancerous lesions in HIV-infected individuals. The standard treatment for anal cancer has been fluorouracil (5-FU) and mitomycin (or cisplatin) as chemotherapy agents plus radiation, which can also be effectively used for the HIV-infected patients. Continued studies will be needed to test new treatment strategies in HIV-infected patients with anal cancer to determine which treatment protocols provide the best therapeutic index. PMID:27889034

To describe pain severity and pain interference and to explore the impact of pain severity on postoperative health-related quality of life of older people during their first year after discharge for hip surgery in Taiwan. Few studies have examined the impact of pain on postoperative quality of life for hip-fractured older persons. A descriptive, correlational design was used for this longitudinal study. Pain intensity, pain interference and quality of life were investigated prospectively for 87 elders within 12 months after discharge for hip surgery at a medical centre in Taiwan. Pain intensity and pain interference were measured by items from the Bodily Pain scale of the Medical Outcomes Study Short Form-36, Taiwan version. Quality of life dimensions were measured by all instrument scales, except bodily pain. Moderate to severe pain was reported by 41.3% and 24(.)8% of subjects at one and 12 months following discharge, respectively. Pain interference with life was reported as quite a bit or extreme by 31.1% of subjects at 12 months after discharge. Subjects who reported moderate/severe pain at one month after discharge experienced declines in general health (p = 0.03) and vitality (p = 0.02) from 6-12 months after discharge. Around a quarter of hip-fractured older persons experienced moderate to very severe pain and quite a bit to severe pain interference from six months to one year after discharge. Furthermore, pain experienced during the first month after discharge significantly impacted quality of life throughout the year following discharge, even after controlling for covariates. Nurses must pay attention and intervene with long-term postoperative pain in hip-fractured elders to prevent further declines in physically related outcomes. The findings of this study can be used to develop effective pain-management strategies for hip-fractured older patients.

The need for anal dysplasia screening and treatment programs for HIV-infected men who have sex with men: a review of the literature.

Roark, Randall

2011-01-01

Anal cancer rates, which were higher for men who have sex with men (MSM) compared to the general population before HIV, increased dramatically after the HIV epidemic began and continue to increase in HIV-infected MSM despite the advent of antiretroviral therapy and associated immune reconstitution. Because of the similarity to cervical cancer and an established link to human papillomavirus infection, many experts have called for widespread implementation of anal cytological screening and treatment programs, especially for HIV-infected MSM. However, other experts argue that it is too early for widespread implementation of such programs for reasons including lack of clear evidence that anal dysplasia is a precursor to anal cancer, or that detecting and treating anal dysplasia reduces the risk for developing anal cancer; lack of effective treatments for anal dysplasia when it is discovered; and lack of resources. This paper reviews current literature regarding these issues. Copyright © 2011 Association of Nurses in AIDS Care. Published by Elsevier Inc. All rights reserved.

2014-11-01

This study was designed to determine postoperative pain levels after ear, nose, and throat (ENT) surgery, and also to examine whether intraoperative fentanyl use during ENT surgery enhances the quality of postoperative pain control. The distribution of pain scores and rescue analgesic requirements among 198 patients undergoing ENT surgery were examined. Multivariate logistic regression analysis was performed to identify independent factors associated with moderate to severe postoperative pain (maximal pain score ≥ 5 on the numerical rating scale) and postoperative nausea and vomiting (PONV). 27.8% of patients experienced moderate to severe postoperative pain after ENT surgery. The distribution of postoperative pain levels was similar among procedures performed on different anatomical regions. Intraoperative fentanyl use was not associated with moderate to severe postoperative pain (adjusted odds ratio (95% confidence interval) :1.03 (0.51-2.13))]. On the other hand, intraoperative fentanyl use was independently associated with PONV [3.10 (1.25-8.92); P = 0.0138]. Prevalence of moderate to severe postoperative pain after ENT surgery was approximately 28%. Intraoperative fentanyl use was not associated with a decreased incidence of moderate to severe postoperative pain, but was significantly associated with PONV.

Background Pain is a prominent feature of acute dengue as well as a clinical criterion in World Health Organization guidelines in diagnosing dengue. We conducted a prospective cohort study to compare levels of pain during acute dengue between different ethnicities and dengue severity. Methods Demographic, clinical and laboratory data were collected. Data on self-reported pain was collected using the 11-point Numerical Rating Scale. Generalized structural equation models were built to predict progression to severe disease. Results A total of 499 laboratory confirmed dengue patients were recruited in the Prospective Adult Dengue Study at Tan Tock Seng Hospital, Singapore. We found no statistically significant differences between pain score with age, gender, ethnicity or the presence of co-morbidity. Pain score was not predictive of dengue severity but highly correlated to patients’ day of illness. Prevalence of abdominal pain in our cohort was 19%. There was no difference in abdominal pain score between grades of dengue severity. Conclusion Dengue is a painful disease. Patients suffer more pain at the earlier phase of illness. However, pain score cannot be used to predict a patient’s progression to severe disease. PMID:24788828

To evaluate anal sphincter anatomy using three-dimensional ultrasonography (3-DAUS) in incontinent women with vaginal delivery, correlate anatomical findings with symptoms of fecal incontinence and determine the effect of vaginal delivery on anal canal anatomy and function. Female with fecal incontinence and vaginal delivery were assessed with Wexner's score, manometry, and 3DAUS. A control group comprising asymptomatic nulliparous was included. Anal pressure, the angle of the defect and length of the external anal sphincter (EAS), the anterior and posterior internal anal sphincter (IAS), the EAS + puborectal and the gap were measured and correlated with score. Of the 62, 49 had fecal incontinence and 13 were asymptomatic. Twenty five had EAS defects, 8 had combined EAS+IAS defects, 16 had intact sphincters and continence scores were similar. Subjects with sphincter defects had a shorter anterior EAS, IAS and longer gap than women without defects. Those with a vaginal delivery and intact sphincters had a shorter anterior EAS and longer gap than nulliparous. We found correlations between resting pressure and anterior EAS and IAS length in patients with defects. Fecal incontinence symptoms did not correlate with anal pressures and anal sphincter anatomy changes, but women with sphincter defects have shorter anterior EAS and IAS and a longer gap.

To assess the normal anatomy of the anal sphincter complex using high-resolution MR imaging with phased -array coil. Twenty patients, 13 males and 7 females, ranging in age between 27 and 56 years underwent MRI evaluation of the pelvic region, using a superconductive 1.5 T magnet (maximum gradient strength, 25 mT/m; minimum rise time 600 microseconds, equipped with phased-array coil. High-resolution T2-weighted Turbo Spin Echo sequences (TR, 4055 ms; TE, 132 ms; matrix 390x512; in-plane resolution, 0.67x0.57 mm) were acquired on multiple axial, sagittal and coronal planes. Images were reviewed by two experienced gastrointestinal radiologists in order to evaluate the normal anal sphincter complex. Optimal image quality of the anal sphincter complex was obtained in all cases. Different muscular layers were observed between the upper and lower aspects of the anal canal. In the lower part of the anal canal, internal and external sphincter muscles could be observed; in the upper part, puborectal and internal sphincter muscles were depicted. Good visualization of intersphincteric space, levator ani muscle and ischioanal space was also obtained in all cases. High-resolution MR images with phased-array coil provide optimal depiction of the anal canal and the anal sphincter complex.

Human papillomavirus (HPV)-related anal cancer lesions are often found adjacent to the squamocolumnar junction (SCJ). We have assessed the histopathology and associated HPV genotypes in anal SCJ lesions in surgically excised anal warts in HIV-negative and -positive patients. Histopathology identified 47 squamous intraepithelial lesions (SILs) adjacent to the SCJ amongst a total of 145 cases of clinically diagnosed anal condylomata. The anal SCJ lesions were further analyzed with p16, CK7 and p63 immunohistochemistry and HPV genotyping. Sixteen (16/47) of the excised anal wart lesions contained HSIL; Three were HSIL and exclusively associated with oncogenic HPVs. A further thirteen (13/47) were mixed lesions. Of these eight were HSILs with LSIL and six were HSILs with papillary immature metaplasia (PIM); Ten of the mixed lesions were associated with one or more oncogenic HPVs, while three cases were exclusively associated with HPV6. Clinically diagnosed anal warts cannot be assumed to be limited to low-grade lesions as anal warts of the SCJ often show heterogeneous lesions, with coexistence of LSIL, PIM, and HSIL. Lesions showing PIM, however, may mimic HSIL, because they are hypercellular, but lack the nuclear atypia and conspicuous mitotic activity of HSIL; and are p16 negative. Copyright © 2016 The Authors.

Although the primary cause of anal cancer is human papillomavirus (HPV) infection in the anal canal, little attention has been paid to the epidemiology of anal HPV infection in men who have sex with women (MSW). Exfoliated cells from the anal canal of 902 MSW in Brazil (São Paulo), Mexico (Cuernavaca), and the United States (Tampa) were tested for HPV DNA. The prevalence of HPV infection in the anal canal (12.0%) was similar among MSW in each city (P=.77), whereas 7.0% had infection with oncogenic types. Men in Tampa had a 4-fold higher prevalence of infection with HPV type 16 (HPV-16) than that among men in São Paulo or Cuernavaca (P<.001). Duration of relationship with a primary sex partner and ever having oral or anal sex with a man was associated with infection with any HPV type and with any oncogenic type, whereas lifetime number of female sex partners was associated with infection with any HPV type. Anal canal HPV infection is commonly found among MSW, and the prevalence of infection with HPV-16 may differ substantially by geography. Men who have a larger lifetime number of female sex partners, who are in a sexual relationship of <1 year in duration, and who have a history of oral or anal sex with men were most likely to have an anal HPV infection.

To determine the prevalence and risk factors for dysplasia in an urban population of HIV-infected young men who have sex with men (YMSM) and to determine the adherence to guidelines for anal cytology screening. The electronic medical record was utilized to collect pre-existing demographic information, medical history, laboratory data, and anal cytology results. Among 60 subjects (mean age 21.2 years) at their first diagnostic anal cytology, 32 (53.3%) had an anal cytological abnormality and 28 (46.7%) had normal anal cytology. The abnormal results were as follows: 21 (65.6%) had atypical squamous cells of undetermined significance (ASCUS), one (3.1%) had atypical squamous cells and high-grade squamous intraepithelial lesion could not be excluded, nine (28.1%) had low-grade squamous intraepithelial lesion, and one (3.1%) had high-grade squamous intraepithelial lesion. In univariate analysis, abnormal anal cytology was not associated with any of the identified risk factors. The proportion of YMSM at the HIV Specialized Care Center who had an anal cytology screen rose from 32.3% (10/31) in 2008, the first full year of anal cytology screening at this clinic, to 81.4% (35/43) in 2012. The prevalence of abnormal anal cytology in this YMSM population is similar to the prevalence in other, primarily adult men who have sex with men, HIV-infected populations. Further studies are necessary to determine risk factors and outcomes of abnormal test results in HIV-infected YMSM populations.

This study analyzed event-level partnership data from a computer-assisted survey of 719 gay and bisexual men (GBM) enrolled in the Momentum Health Study to delineate potential linkages between anal sex roles and so-called “sex drugs”, i.e. erectile dysfunction drugs (EDD), poppers and crystal methamphetamine. Univariable and multivariable analyses using generalized linear mixed models with logit link function with sexual encounters (n=2,514) as the unit of analysis tested four hypotheses: 1) EDD are significantly associated with insertive anal sex roles, 2) poppers are significantly associated with receptive anal sex, 3) both poppers and EDD are significantly associated with anal sexual versatility and, 4) crystal methamphetamine is significantly associated with all anal sex roles. Data for survey respondents and their sexual partners allowed testing these hypotheses for both anal sex partners in the same encounter. Multivariable results supported the first three hypotheses. Crystal methamphetamine was significantly associated with all anal sex roles in the univariable models, but not significant in any multivariable ones. Other multivariable significant variables included attending group sex events, venue where first met, and self-described sexual orientation. Results indicate that GBM sex-drug use behavior features rational decision-making strategies linked to anal sex roles. They also suggest that more research on anal sex roles, particularly versatility, is needed, and that sexual behavior research can benefit from partnership analysis. PMID:26525571

Indirect and direct trauma following vaginal birth can negatively impact on the pelvic floor function increasing the risk of anal incontinence. It is often difficult for women to openly disclose that they have anal incontinence and there are limited data collection tools available for the identification of these women in a clinical setting. This study aims to describe the prevalence of undisclosed anal incontinence in antenatal and postnatal women with pelvic floor dysfunction. Retrospective cohort study of 230 antenatal and postnatal women referred to a Continence Nursing Service in a large tertiary hospital in South Australia, Australia, with pelvic floor dysfunction. A criteria list was utilised to access the primary reason for referral, anal incontinence assessments and attendance to an appointment. Anal incontinence was identified in 26% of women (n=59). Anal incontinence was the primary reason for referral amongst 8 women, with the remaining 51 women identified as having anal incontinence following clinical screening via phone consultation. Eighty six percent of women stated they had not previously disclosed anal incontinence to health professionals. Overall, 71% of symptomatic women (n=28 antenatal and n=14 postnatal women) attended appointments to a service specialising in pelvic floor dysfunction. Women presenting with urinary incontinence or other markers of pelvic floor dysfunction should be actively screened for anal incontinence as the prevalence of this condition is high amongst childbearing women.

We studied prevalence, risk factors and concordance of vaginal and anal HPV infection and L1 seropositivity among female sex workers (FSW) in Amsterdam. In 2016, FSW aged ≥18 years having a sexually transmitted infections (STI) consultation were invited to participate. Participation entailed taking vaginal and anal self-swabs. Demographics and sexual behaviour data were collected. HPV DNA was analysed using the SPF10-PCR-DEIA-LiPA25-system-v1. Serum was tested for HPV L1 antibodies using multiplex serology assays. Determinants of vaginal and anal high risk HPV (hrHPV) infection and L1 seropositivity were assessed with logistic regression analyses. We included 304 FSW; median age was 29 years (IQR 25-37). Vaginal and anal hrHPV prevalence were 46% and 55%, respectively. HrHPV L1 seropositivity was 37%. Vaginal-anal hrHPV concordance was strong, but no significant association between vaginal or anal hrHPV infection and seropositivity was found. Having had anal sexual contact was not associated with anal hrHPV infection (P = 0.119). Vaginal and anal hrHPV prevalence is high among FSW in Amsterdam, the Netherlands. Promotion of HPV vaccination, preferably at the beginning of the sex (work) career, may be a useful prevention method against hrHPV infection and disease.

India has a large population of HIV-positive individuals, including men who have sex with men (MSM), and the incidence of human papillomavirus (HPV)-related cancers is high. In developed countries, HIV-positive MSM exhibit the highest prevalence of anal HPV infection and incidence of anal cancer. Little is known about anal HPV infection in HIV-positive Indian MSM. We evaluated 300 HIV-positive MSM from 2 cities in India. Men were tested for anal HPV infection using L1-HPV DNA polymerase chain reaction with probes specific for 29 types and a mixture of 10 additional types. CD4 level and plasma HIV viral load were measured. Participants completed an interviewer-administered questionnaire including a sexual history. The prevalence of anal HPV was 95% (95% confidence interval: 91% to 97%). The 3 most common types were HPV 35 (20%), HPV 16 (13%), and HPV 6/11 (13%). History of taking antiretroviral medications decreased risk of anal HPV 16 infection [relative risk (RR): 0.6 (0.4-1.0)]. Having an increased number of vaginal sex partners lowered risk of any anal HPV infection. Ever having receptive sex increased risk of any anal HPV [RR: 1.2 (1.1-1.4)] and anal HPV 16 [RR: 6.5 (1.8-107)]. Almost all Indian HIV-positive MSM had anal HPV infection. The prevalence of HPV 16 was lower and the prevalence of other oncogenic HPV types was higher than in similar populations in North America and Europe. Vaccine-based prevention strategies for HPV infection in India should consider potential differences in HPV type distribution among HIV-infected MSM when designing interventions.

Anal cancer is more common in women than in men, yet little is known about the natural history of human papillomavirus (HPV) in women. The objective was to examine the natural history of anal HPV in heterosexual women. Young women participating in an HPV cohort study were seen at 4-month intervals for cervical and anal HPV testing. Time to clearance was estimated using the Kaplan-Meier approach; risks for persistence were assessed using Cox regression models. Seventy-five women (mean age, 23.5 ± 4.1 years) who tested positive for anal HPV were followed for a mean of 84.5 ± 44.9 months. By 3 years, 82.5% of anal non-16 high-risk (HR) HPV, 82.6% of low-risk (LR) HPV, and 76.2% of HPV-16 infections had cleared. By 3 years, only 36.4% of women had become negative for all HPV types. In the multivariable model, concurrent cervical HPV-16 (P < .001), weekly alcohol use (P = .015), anal touching during sex (P = .045), recent anal sex (P = .04), and no condom use during anal sex (P = .04) were associated with HPV-16 persistence. Greater number of new sex partners (P = .024) and condom use during vaginal sex (P = .003) were associated with clearance. Similar associations were found for clearance in all HR-HPV infections. Only concomitant cervical HPV was associated with non-16 HR-HPV persistence. The majority of anal HPV infections cleared within 3 years. HPV-16 infections were slower to clear than other HR-HPV infections, consistent with its role in anal cancer. Specific sexual behaviors were associated with persistence, suggesting that education and behavioral interventions may decrease persistence.

Little is known about the incidence of anal human papillomavirus (HPV) infection and related sequelae, as well as factors associated with these outcomes, among adolescents who are HIV infected versus HIV uninfected but at risk. We analyzed the data from a multisite US study, the Reaching for Excellence in Adolescent Care and Health Project. Adolescents aged 12 to 18 years who were behaviorally HIV infected (n = 319) or HIV uninfected but at risk (n = 177) were recruited. Incidence rates for anal HPV, high-risk anal HPV, anogenital warts, and anal dysplasia were calculated using Poisson modeling. Factors associated with these outcomes were examined using Cox proportional hazards modeling. Mean age at entry was 16.8 years; mean (SD) follow-up time for detection of anal HPV was 22.4 (10.8) months. Most participants (76%) were female; 70% were black non-Hispanic. HIV-infected (vs. HIV-uninfected) women had a significantly higher incidence of anal HPV (30 vs. 14 per 100 person-years; P = 0.002), high-risk anal HPV (12 vs. 5.3 per 100 person-years; P = 0.04), and anogenital warts (6.7 vs. 1.6 per 100 person-years; P = 0.002) but not anal dysplasia. Although incidence rates were higher for these outcomes among HIV-infected versus HIV-uninfected men, the differences were not statistically significant. Among women, factors associated with anal HPV and related sequelae differed by HIV status and included biological, behavioral, and HIV-related factors. No factors were associated with outcomes in men. HIV-infected versus HIV-uninfected adolescent women had higher rates of anal HPV and anogenital warts. Because HIV-infected youth are at increased risk of these outcomes, enhanced HPV prevention efforts such as vaccination are warranted for this group.

In Western countries, tuberculous anal fistula may not be an issue because tuberculosis [TB] is not common, and this is a very rare form of extrapulmonary manifestation of TB. However in TB-endemic countries, careful diagnostic differentiation is required because the clinical features of TB anal fistula and Crohn's disease [CD] anal fistula are similar, with distinguishing features remaining unclear. We aimed to analyse the clinical features of TB versus CD anal fistulas. Among 13872 patients who underwent anal fistula surgery from 2003 to 2014, 87 patients with TB fistulas and 116 patients with CD fistulas were included. Data on the annual incidence of TB and CD, as well as the clinical, pathological, ultrasonographic, colonoscopic and surgical data were analysed. Compared with CD, the TB group was older [median: 37 vs 22 years] and underlying chronic illness was more common [20.3% vs 2.6%]. In the TB group, 46 patients [59.7%] showed active or inactive pulmonary TB, and acid-fast bacilli and caseating granuloma were found in 56.3% and 62.1%, respectively. During colonoscopy, mucosal lesions were observed more frequently in CD [96.9% vs 16.9%]. TB anal fistula is clinically very similar to CD anal fistula. In Korea, the incidence of CD anal fistula has recently increased in prevalence, whereas the prevalence of TB anal fistula is decreasing but is still persistent. We recommend that clinicians should prepare for a possibility of TB as well as CD anal fistula in TB-endemic countries including Korea.

Anal sex is an efficient mode of STI transmission and studies indicate that anal sex is common among heterosexuals, including adolescents. We examined the association between individual, partner, and sexual partnership-level characteristics with anal sex among a household survey of 263 individuals aged 15-24 years in Baltimore City, Maryland. We used weighted multiple logistic regression to examine correlates of anal sex in a heterosexual partnership by gender. Twenty-nine percent of males and 15% of females reported anal sex in a partnership in the past 6 months. For males, anal sex was associated with having two or more partners in the past 3 months (AOR = 13.93, 95% CI 3.87-50.12), having been tested for HIV (AOR = 0.30, 95% CI 0.12-0.72), and oral sex with a partner (AOR = 8.79, 95% CI 1.94-39.78). For females, anal sex was associated with reporting having a main partner (AOR = 6.74, 95% CI 1.74-23.65), partner meeting place (AOR = 3.03, 95% CI 1.04-8.82), partner history of STI (AOR = 0.20, 95% CI 0.05-0.85), and oral sex with a partner (AOR = 8.47, 95% CI 1.08-66.25). Anal sex was associated with inconsistent condom use for both males (OR = 5.77, 95% CI 1.68-19.79) and females (OR = 5.16, 95% CI 1.46-18.30). We conclude that anal sex is a prevalent risk behavior among heterosexual youth and is associated with a range of factors at the individual and partnership levels. These findings provide support for comprehensive sex education that includes information about anal sex; findings from this study can inform public health campaigns targeting youth at risk for STIs.

This study aimed to evaluate the incidence of anal dysplasia in women at high risk of developing those lesions and to assess the relationships between positive anal cytology and different risk factors. We performed an observational cross-sectional study involving a patient survey and chart review. The study was conducted at the cervical pathology unit at the Hospital Universitario 12 de Octubre, Madrid, Spain, from 2011 to 2015. Patients were 215 women aged 18 to 65 years old with risk factors for anal dysplasia, for whom anal evaluation was indicated. Anal cytology was performed in all patients. High-resolution anoscopy and anal biopsy were used to investigate abnormalities. All patients completed a survey regarding sexual practices. The patients' demographic and clinical data were collected by using a retrospective chart review. The main outcome measure was the incidence of anal dysplasia in this population. Of the 215 patients, 45 (21.0%) presented with cytological abnormalities (atypical squamous cells of undetermined significance, 13.5%; low-grade squamous intraepithelial lesion, 5.6%; high-grade squamous intraepithelial lesion, 1.9%). Anoscopy was performed in 31 patients (14.4%) and 2 patients (0.9%) had abnormal findings. One case (0.5%) of low-grade anal intraepithelial neoplasia was identified. Only immunosuppression (p = .01) and smoking status (p = .02) were significantly correlated with positive anal cytology results. Limitations of the study include the small single-center sample, a lack of controls, the retrospective design, potential survey response biases, and the nonstandardized survey. The incidence of abnormal cytological findings was 21.0%, whereas low-grade anal intraepithelial was confirmed in 0.5% of the patients. There is a higher incidence of cytological abnormalities among immunosuppressed women and smokers.

The evacuative motor responses of the anal canal and recto-anal reflexes during defecation were studied in an isolated rat recto-anal model preparation using (i) partitioned organ bath, (ii) electrical stimulation, (iii) balloon distension and (iv) morphological techniques. Electrical field stimulation applied to the anal canal or to the distal part of the rectum elicited tetrodotoxin (10(-7) M)-sensitive frequency-dependent local or descending contractions of the anal canal and the local responses were bigger in amplitude (14.9 ± 1.35 mN) than the descending contractions (5.3 ± 0.7 mN at frequency of 5 Hz, p < 0.05). The balloon-induced distension of the distal rectum evoked descending responses of the anal canal consisting of a short contraction (1.50 ± 0.18 mN) followed by deep relaxation (3.12 ± 0.34 mN). In the presence of atropine (3 x 10(-7) M) the electrically-elicited (5 Hz) local or descending contractions of the anal canal were suppressed and a relaxation revealed. The initial contraction component of the distension-induced response was decreased while the relaxation was not changed. During atropine treatment, spantide (10(-7) M) lowered even more the contractile component of the anal canal response. NG-nitro-L-arginine (5 x 10(-4) M) enhanced the contraction, prevented the atropine-dependent relaxation of the electrically-elicited response and inhibited the distension-induced relaxation. L-Arginine (5 x 10(-4) M) suppressed the contraction and extended the relaxation. ChAT-, substance P- and NADPH-diaphorase-positive perikarya and nerve fibers were observed in myenteric ganglia of the anal canal. The results suggest activation-dependent descending reflex motority of the anal canal involving electrical stimulation-displayed cholinergic and tachykininergic and distension manifested nitrergic neuro-muscular communications.

To characterize the rate of obstetric anal sphincter injuries and identify key risk factors of obstetric anal sphincter injuries, including duration of the second stage of labor. This retrospective cohort study included all singleton, term, cephalic vaginal deliveries within Kaiser Permanente Northern California between January 2013 and December 2014 (N=22,741). Incidence of obstetric anal sphincter injuries, defined as third- or fourth-degree perineal lacerations, was the primary outcome. Multiple logistic regression models were conducted to identify obstetric anal sphincter injury risk factors and high-risk subpopulations. The overall incidence rate of obstetric anal sphincter injuries was 4.9% (3.6% of women who delivered spontaneously vs 24.0% of women who had a vacuum-assisted vaginal delivery, P<.001, CI 18.1-22.6%). In bivariate and multivariate analyses, obstetric anal sphincter injury incidence was higher among women with second stage of labor longer than 2 hours, Asian race, nulliparity, vaginal birth after cesarean delivery, episiotomy, and vacuum delivery. Women with a vacuum-assisted vaginal delivery had four times the odds of obstetric anal sphincter injury (adjusted odds ratio [OR] 4.23, 95% CI 3.59-4.98) and those whose second stage of labor lasted at least 180 minutes vs less than 60 minutes had three times the odds of incurring obstetric anal sphincter injury (adjusted OR 3.20, 95% CI 2.62-3.89). Vacuum-assisted vaginal delivery conferred the highest odds of obstetric anal sphincter injury followed by prolonged duration of the second stage of labor, particularly among certain subpopulations. Understanding these risk factors and their complex interactions can inform antepartum and intrapartum decision-making with the goal of reducing obstetric anal sphincter injury incidence.

The aim of the study was to estimate the magnitude of the association between HPV-related gynecological neoplasms and secondary anal cancer among women in Puerto Rico (PR). We identified 9,489 women who had been diagnosed with a primary cervical, vaginal, or vulvar tumor during 1987-2013. To describe the trends of invasive cervical, vulvar, vaginal, and anal cancer, the age-adjusted incidence rates were estimated using the direct method (2000 US as Standard Population). Standardized incidence ratios (observed/expected) were computed using the indirect method; expected cases were calculated using 2 methods based on age-specific rates of anal cancer in PR. The ratio of standardized incidence ratios of anal cancer was estimated using the Poisson regression model to estimate the magnitude of the association between HPV-gynecologic neoplasms and secondary anal cancer. A significant increase in the incidence trend for anal cancer was observed from 1987 to 2013 (annual percent change = 1.1, p < .05), whereas from 2004 to 2013, an increase was observed for cervical cancer incidence (annual percent change = 3.3, p < .05). The risk of secondary anal cancer among women with HPV-related gynecological cancers was approximately 3 times this risk among women with non-HPV-related gynecological cancers (relative risk = 3.27, 95% CI = 1.37 to 7.79). Anal cancer is increasing among women in PR. Women with gynecological HPV-related tumors are at higher risk of secondary anal cancer as compared with women from the general population and with those with non-HPV-related gynecological cancers. Appropriate anal cancer screening guidelines for high-risk populations are needed, including women with HPV-related gynecological malignancies and potentially other cancer survivors.

Trends in incidence and survival for anal cancer in New South Wales, Australia, 1972-2009.

Little is known about the incidence and survival of anal cancer in New South Wales (NSW), Australia, as anal cancer cases are often grouped together with other colorectal cancers in descriptive epidemiological analyses. We studied patterns and trends in the incidence and survival of people diagnosed with anal cancer in NSW, Australia, 1972-2009 (n=2724). We also predicted anal cancer incidence in NSW during 2010-2032. Given the human papilloma virus-associated aetiology for most anal cancers, we quantified these changes over time in incidence and survival by histological subtype: anal squamous cell carcinoma (ASCC); and anal adenocarcinoma (AAC). There was a linear increase in incident anal cancer cases in NSW with an average annual percentage change (AAPC) of 1.6 (95% CI 1.1-2.0) such that, in combination with age-period-cohort modelling, we predict there will be 198 cases of anal cancer in the 2032 calendar year (95% CI 169-236). Almost all of these anal cancer cases are projected to be ASCC (94%). Survival improved over time regardless of histological subtype. However, five-year relative survival was substantially higher for people with ASCC (70% (95% CI 66-74%)) compared to AAC (51% (95% CI 43-59%)), a 37% difference. Survival was also greater for women (69% (95% CI 64-73%)) with ASCC compared to men (55% (95% CI 50-60%)). It was not possible to estimate survival by stage at diagnosis particularly given that 8% of all cases were recorded as having distant stage and 22% had missing stage data. Aetiological explanations, namely exposure to oncogenic types of human papillomavirus, along with demographic changes most likely explain the actual and projected increase in ASCC case numbers. Survival differences by gender and histological subtype point to areas where further research is warranted to improve treatment and outcomes for all anal cancer patients.

Obstetric anal sphincter tears are common and an important factor in the etiology of anal incontinence. The objective of the study was to evaluate the prevalence of residual defects of the external anal sphincter (EAS) after primary repair of obstetric anal sphincter injury using four-dimensional (4D) transperineal ultrasound and to correlate sonographic findings of residual defects and levator avulsion with significant symptoms of anal incontinence, defined as St Mark's fecal incontinence score (SMIS) of ≥ 5. This was a retrospective observational study. One-hundred and forty women were seen after primary repair of obstetric anal sphincter tears in a dedicated perineal clinic at a tertiary hospital in Australia. They all underwent a standardized interview, and physical and 4D transperineal ultrasound examination. Mean follow-up interval was 1.9 months after delivery. Eighty-nine (64%) women had a 3a/3b tear, 28 (20%) a 3c/4(th) degree tear and 23 (16%) an unclassified 3(rd) degree tear. Thirty-five (25%) patients reported symptoms of anal incontinence. Nine had an SMIS of ≥ 5. A residual defect was found in 56 (40%) cases and levator avulsion in 27 (19%). On multivariate logistic regression, residual defects (P = 0.03; odds ratio (OR) = 6.38; 95% CI, 1.23-33.0) and levator avulsion (P = 0.047; OR = 4.38; 95% CI, 1.02-18.77) were found to be independent risk factors for anal incontinence. Residual defects of the EAS were found on transperineal ultrasound in 40% of women after primary repair of obstetric anal sphincter injuries. Although most were asymptomatic, residual anal sphincter defects and levator avulsion were associated with significant symptoms of anal incontinence as quantified using the SMIS.

Human immunodeficiency virus (HIV)-infected women have a higher burden of anal high-grade squamous intraepithelial lesions (HSIL) and anal cancer (AC) compared with HIV-uninfected women. Guidelines for AC screening in this population are heterogeneous. Here we report outcomes and risk factors for anal HSIL following implementation of universal AC screening offered to all HIV-infected women. Data from women who underwent AC screening with anal cytology from April 2009 to July 2014 were analyzed. Routine clinical data included anal and cervical cytology, demographic/behavioral data, and high-resolution anoscopy (HRA) results. We evaluated the association of cytology with HRA results, and predictors of HSIL pathology, and compared rates of HSIL pathology among women meeting screening guidelines to those who did not. Seven hundred forty-five HIV-infected women were screened with anal cytology. Thirty-nine percent had abnormal anal cytology on initial screen and 15% on secondary screen; 208 women underwent HRA following abnormal anal cytology. HSIL was found in 26% and 18% of anal biopsies following initial and secondary screening, respectively. One woman had AC. Cigarette smoking more than doubled HSIL risk. Among women who underwent AC screening despite not meeting existing guideline criteria, 21% and 10%, respectively, were found to have HSIL on biopsy. Neither meeting criteria for screening nor history of receptive anal sex was significantly associated with HSIL. Anal HSIL is common in HIV-infected women. Substantial numbers of HSIL would have been missed by strictly adhering to existing AC screening guidelines. These results support routine screening of all HIV-infected women regardless of human papillomavirus history or sexual practices. © The Author 2016.

HP (2-20) is a 19-aa, amphipathic, α-helical peptide with antimicrobial properties that was derived from the N-terminus of Helicobacter pylori ribosomal protein L1. We previously showed that increasing the net hydrophobicity of HP (2-20) by substituting Trp for Gln(17) and Asp(19) (Anal 3) increased the peptide's antimicrobial activity. In hydrophobic medium, Anal 3 forms an amphipathic structure consisting of an N-terminal random coil region (residues 2-5) and an extended helical region (residues 6-20). To investigate the structure-activity relationship of Anal 3, we substituted Pro for Glu(9) (Anal 3-Pro) and then examined the new peptide's three-dimensional structure, antimicrobial activity and mechanism of action. Anal 3-Pro had an α-helical structure in the presence of trifluoroethanol (TFE) and sodium dodecyl sulfate (SDS). NMR spectroscopic analysis of Anal 3-Pro's tertiary structure in SDS micelles confirmed that the kink potential introduced by Pro(10) was responsible for the helix distortion. We also found that Anal 3-Pro exhibited about 4 times greater antimicrobial activity than Anal 3. Fluorescence activated flow cytometry and confocal fluorescence microscopy showed that incorporating a Pro-hinge into Anal 3 markedly reduced its membrane permeability so that it accumulated in the cytoplasm without remaining in the cell membrane. To investigate the translocation mechanism, we assessed its ability to release of FITC-dextran. The result showed Anal 3-Pro created a pore <1.8 nm in diameter, which is similar to buforin II. Notably, scanning electron microscopic observation of Candida albicans revealed that Anal 3-Pro and buforin II exert similar effects on cell membranes, whereas magainin 2 exerts a different, more damaging, effect. In addition, Anal 3-Pro assumed a helix-hinge-helix structure in the presence of biological membranes and formed micropores in both bacterial and fungal membranes, through which it entered the cytoplasm and tightly bound to DNA. These results indicate that the bending region of Anal 3- Pro peptide is prerequisite for effective antibiotic activity and may facilitate easy penetration of the lipid bilayers of the cell membrane.

Spasm of the internal sphincter plays a role in hemorrhoidal disease and may be a source of anal pain after hemorrhoid surgery. We have evaluated the effects of topical diltiazem, a calcium channel blocker, in reducing pain after hemorrhoidectomy. After hemorrhoidectomy, 18 patients were randomly assigned to receive 2 percent diltiazem ointment (n = 9) or a placebo ointment (n = 9). Ointments were applied to the perianal region three times daily for seven days. Patients were prescribed hydrocodone bitartrate (Vicodin) to take as needed. The type and number of prescribed or nonprescribed medications taken during the postoperative period were recorded. Patients maintained a log to measure postoperative pain daily and perceived benefit of the ointment, using a Visual Analog Scale ranging from 0 to 10. Any postoperative morbidity noted during the follow-up period was recorded. Patients using the diltiazem ointment had significantly less pain and greater benefit than those in the placebo group throughout the first postoperative week. Postoperative pain scores in the placebo group averaged 8.8 +/- 1.2 early and diminished to 5.2 +/- 1.7 at the end of one week, compared to the diltiazem group of 5.2 +/- 2.4 early and 2.3 +/- 1.2 at the end of one week (P < 0.001, both time periods). Perceived benefit in the placebo group averaged 2.7 +/- 1.2 vs. 5.6 +/- 1.4 in the diltiazem group (P < 0.001). Total and daily narcotic use was higher in the placebo group, but this was not statistically significant (P = 0.13). No differences in the frequency of use of nonsteroidal anti-inflammatory drugs and acetaminophen were seen between the two groups, and there were no differences in morbidity between the two groups. Perianal application of 2 percent diltiazem ointment after hemorrhoidectomy significantly reduces postoperative pain and is perceived as beneficial, with no increase in associated morbidity. Patients using a placebo ointment tend to take more prescription narcotics for pain relief postoperatively, with a similar usage of nonsteroidal anti-inflammatory drugs and acetaminophen, although differences were not significant.

While increasing evidence suggests that observers discount high-severity chronic pain, factors that occasion such discounting are poorly understood, particularly regarding health provider vs lay perspectives. This study examined the effects of supporting medical evidence and comorbid psychological distress (pain behavior) on medical student and lay clinical judgments of increasingly severe patient pain reports. In a 2 × 2 × 2 × (7) mixed between- and within-subject design, participants (medical students vs lay) made clinical judgments after reading vignettes describing a hypothetical patient that varied in levels of medical evidence and pain behavior (low vs high) and pain severity (4/10-10/10). Fourth-year medical students (N = 115) and lay persons in the community (N = 300) participated in this research. While both medical student and lay judgments plateaued at high levels of pain severity, judgments regarding cause (medical vs psychological), treatment (opioid prescription), and disability showed growing divergence as levels of reported pain severity increased. Divergence relative to medical and psychological causes of pain was found irrespective of the level of supporting medical evidence; divergence relative to opioid treatment and support for a disability claim was found when supporting medical evidence was low. The results indicate differing expectations of chronic pain treatment for health care providers relative to the lay public that could impact clinical care, especially at high pain severity levels, where lay expectations diverge significantly from those of health professionals. © 2015 American Academy of Pain Medicine.

Partners' Overestimation of Patients' Pain Severity: Relationships with Partners' Interpersonal Responses.

PubMed

Junghaenel, Doerte U; Schneider, Stefan; Broderick, Joan E

2017-09-26

The present study examined whether concordance between patients' and their partners' reports of patient pain severity relates to partners' social support and behavioral responses in couples coping with chronic pain. Fifty-two couples completed questionnaires about the patient's pain severity. Both dyad members also rated the partner's social support and negative, solicitous, and distracting responses toward the patient when in pain. Bivariate correlations showed moderate correspondence between patient and partner ratings of pain severity (r = 0.55) and negative (r = 0.46), solicitous (r = 0.47), and distracting responses (r = 0.53), but lower correspondence for social support (r = 0.28). Twenty-eight couples (54%) were concordant in their perceptions of patient pain; partners overestimated pain in 14 couples (27%), and partners underestimated pain in 10 couples (19%). Couple concordance in pain perceptions was not related to patients' reports; however, it significantly predicted partners' reports: Partners who overestimated pain reported giving more social support (β = 0.383, P = 0.016), fewer negative responses (β = -0.332, P = 0.029), and more solicitous responses (β = 0.438, P = 0.016) than partners who were in agreement or who underestimated pain. Partner overestimation of pain severity is associated with partner-reported but not with patient-reported support-related responses. This finding has important clinical implications for couple interventions in chronic pain. © 2017 American Academy of Pain Medicine. All rights reserved.

To evaluate the effect of interventions for general practitioners and nursing home staff to improve pain severity and appropriateness of pain medication in nursing home residents (NHR). This cluster-randomized controlled trial was conducted in six nursing homes in the intervention and control group, respectively. Pain management was analysed before (T0) and after (T1, T2) an educational intervention in 239 NHR, aged ≥65 years, without moderate or severe cognitive impairment. Primary and secondary outcomes were average pain severity and appropriateness of pain medication as determined with the Numeric Rating Scale and Pain Medication Appropriateness Scale (PMASD ), respectively. At T0, 72.2% and 73.7% of NHR (mean age 83 years) reported pain (average pain severity 2.4) in the intervention and control group, respectively. The PMASD at T0 was 53.9 in the intervention group and 60.8 in the control group (p = 0.12), while 20.6% compared to 6.9% (p = 0.009) received no pain medication in the two groups. At T2, non-significant improvements in the average pain severity (1.59) and PMASD (61.07) were observed in the intervention group. Moreover, the mean individual PMASD increased by 8.09 (p = 0.03) and the proportion of NHR without pain medication decreased by 50% (p = 0.03) in the intervention group. No appreciable changes were found in the control group at T2. NHR exhibited a high prevalence of pain with overall low severity, while a high proportion of individuals received inappropriate pain medications. Both findings were not significantly improved by the intervention, although some aspects of drug treatment were meaningful improved. © 2015 European Pain Federation - EFIC®

Objective Parental pain catastrophizing is a construct recognized to have a significant impact on experience of pain in both children and parents. This research aimed to investigate the probable relationship of parental pain catastrophizing with the parent’s reports of children’s anxiety, depression and headache severity amongst Iranian parents of children with chronic or recurrent headache. Materials & Methods This study was conducted in 2015-16, in two pediatric neurological centers located in Tehran, Iran; with a convenience sampling method and 212 parents (120 mothers and 92 fathers) of 132 children with a chronic or recurrent headache (migraine and tension-type). They completed the Pain Catastrophizing Scale; Numeric Pain Rating Scale, asking for the average of pain severity in last three months before the research, and the Anxiety and Depression subscales of the Children Behavioral Check List. Results The mean age of parents was 35.41 yr (SD=5.58) and the mean age of children was 9.83 yr (SD=2.77). A total of 72 girls and 60 boys participated in this study with a mean pain severity for headache in last three months before the research of 4.99 (SD=2.63). Probable sex differences according to parental pain catastrophizing, pain severity, anxiety, and depression were assessed amongst parents. In the next step, the predictability of pain severity from parental pain catastrophizing was evaluated. Results indicated a significant relationship in maternal pain catastrophizing and estimates of pain intensity by mothers. Conclusion These findings represent the importance of parent’s especially mother’s cognitive factors affecting their reports of their children’s pain and related emotional disturbances.

Although foot pain has been linked to fall risk, contributions of pain severity, foot posture, or foot function are unclear. These factors were examined in a cohort of older adults. The purpose of this study was to examine the associations of foot pain, severity of foot pain, and measures of foot posture and dynamic foot function with reported falls in a large, well-described cohort of older adults from the Framingham Foot Study. Foot pain, posture, and function were collected from Framingham Foot Study participants who were queried about falls over the past year (0, 1, and ≥2 falls). Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the relation of falls with foot pain, pain severity, foot posture, and foot function adjusting for covariates. The mean age of the 1,375 participants was 69 years; 57% were female, and 21% reported foot pain (40% mild pain, 47% moderate pain, and 13% severe pain). One-third reported falls in the past year (1 fall: n = 263, ≥2 falls: n = 152). Foot pain was associated with a 62% increased odds of recurrent falls. Those with moderate and severe foot pain showed increased odds of ≥2 falls (OR 1.78, CI 1.06-2.99, and OR 3.25, CI 1.65-7.48, respectively) compared to those with no foot pain. Foot function was not associated with falls. Compared to normal foot posture, those with planus foot posture had 78% higher odds of ≥2 falls. Higher odds of recurrent falls were observed in individuals with foot pain, especially severe foot pain, as well as in individuals with planus foot posture, indicating that both foot pain and foot posture may play a role in increasing the risk of falls among older adults. © 2017 S.

Henriksen, Marius; Aaboe, Jens; Bliddal, Henning

2012-08-01

In a cross sectional study, we investigated the relationships between knee pain and mechanical loading across the knee, as indicated by the external knee adduction moment (KAM) during walking in patients with symptomatic knee OA who were distinguished by different radiographic disease severities. Data from 137 symptomatic medial knee OA patients were used. Based on Kellgren/Lawrence (K/L) grading, the patients were divided into radiographically less severe (K/L ≤ 2, n=68) or severe (K/L>2, n=69) medial knee OA. Overall knee pain was rated on a 10 cm visual analog scale, and peak KAM and KAM impulses were obtained from gait analyses. Mixed linear regression analyses were performed with KAM variables as the outcome, and pain and disease severity as independent variables, adjusting for age, gender, and walking speed. In adjusted analyses, less severe patients demonstrated negative relationships between pain intensities and dynamic loading. The severe patient group showed no relationship between pain intensity and peak KAM, and a positive relationship between pain intensity and KAM impulse. In radiographically less severe knee OA, the negative relationships between pain intensity and dynamic knee joint loading indicate a natural reaction to pain, which will limit the stress on the joint. In contrast, either absent or positive relationships between pain and dynamic loading in severe OA may lead to overuse and accelerated disease progression. These findings may have a large potential interest for strategies of treatment in knee OA. Copyright © 2011 Elsevier B.V. All rights reserved.

Incongruence of pain severity ratings among people experiencing pain and their observers has been linked to psychological distress. Previous studies have measured pain rating congruence through static self-report, involving a single rating of pain; however, this method does not capture changes in ratings over time. The present study examined the extent to which partners were congruent on multiple ratings of a participants' pain severity during the cold pressor task. Furthermore, 2 components of pain anxiety-pain catastrophizing and perceived threat-were examined as predictors of pain congruence. Undergraduate couples in a romantic relationship (N = 127 dyads) participated in this study. Both partners completed measures of pain catastrophizing and perceived threat before randomization to their cold pressor participant or observer roles. Participants and observers rated the participant's pain in writing several times over the course of the task. On average, observers rated participants' pain as less severe than participants' rated their own pain. In addition, congruence between partners increased over time because of observers' ratings becoming more similar to participant's ratings. Finally, pain catastrophizing and perceived threat independently and jointly influenced the degree to which partners similarly rated the participant's pain. This article presents a novel application of the cold pressor task to show that pain rating congruence among romantic partners changes over time. These findings indicate that pain congruence is not static and is subject to pain anxiety in both partners. Copyright © 2016 American Pain Society. Published by Elsevier Inc. All rights reserved.

Abdominal pain physiology may be better understood studying electrophysiology, histology, and symptom scores in patients with the symptoms of gastroparesis (Gp) treated with gastric electrical stimulation (GES). Ninety-five Gp patients’ symptoms were recorded at baseline and during temporary and permanent GES. Gastric-emptying times and cutaneous, mucosal, and serosal electrogastrograms were obtained. S100-stained, full-thickness gastric biopsies were compared with autopsy controls. Sixty-eight patients reported severe pain at baseline. Severe pain patients’ mean pain scores decreased with temporary GES from 3.62 to 1.29 (P < 0.001) and nonsevere pain from 1.26 to 0.67 (P = 0.01). With permanent GES, severe mean pain scores fell to 2.30 (P < 0.001); nonsevere pain changed to 1.60 (P = 0.221). Mean follow-up was 275 days. Mean cutaneous, mucosal, and serosal frequencies and frequency-to-amplitude ratios were markedly higher than literature controls. For patients with Gp overall and subdivided by etiology and severity of pain, S-100 neuronal fibers were significantly reduced in both muscularis propria layers. GES improved severe pain associated with symptoms of Gp. This severe pain is associated with abnormal electrogastrographic activity and loss of S100 neuronal fibers in the stomach’s inner and outer muscularis propria and, therefore, could be the result of gastric neuropathy.

2016-01-01

Anal fissure (fissure-in-ano) is a very common anorectal condition. The exact etiology of this condition is debated; however, there is a clear association with elevated internal anal sphincter pressures. Though hard bowel movements are implicated in fissure etiology, they are not universally present in patients with anal fissures. Half of all patients with fissures heal with nonoperative management such as high fiber diet, sitz baths, and pharmacological agents. When nonoperative management fails, surgical treatment with lateral internal sphincterotomy has a high success rate. In this chapter, we will review the symptoms, pathophysiology, and management of anal fissures. PMID:26929749

Although a rare disease, anal cancer is increasingly being diagnosed in patients with risk factors, mainly anal infection with the human papilloma virus. Magnetic resonance imaging (MRI) with external phased-array coils is recommended as the imaging modality of choice to grade anal cancers and to evaluate the response assessment after chemoradiotherapy, with a high contrast and good anatomic resolution of the anal canal. MRI provides a performant evaluation of size, extent and signal characteristics of the anal tumor before and after treatment, as well as lymph node involvement and extension to the adjacent organs. MRI is also particularly helpful in the assessment of complications after treatment, and in the diagnosis for relapse of the diseases.

Allostatic load and pain severity in older adults: Results from the English Longitudinal Study of Ageing

Sibille, Kimberly T.; McBeth, John; Smith, Diane; Wilkie, Ross

2017-01-01

Pain is common in older adults, is frequently experienced as stressful, and is associated with increased morbidity and mortality. Stress regulatory systems are adaptive to challenge and change, allostasis, until demands exceed the adaptive capacity contributing to dysregulation, resulting in a high allostatic load. A high allostatic load is associated with increased risk of morbidity and mortality. Pain severity, based on the average intensity of frequent pain, was hypothesized to be positively associated with AL. Four formulations of AL were investigated. Cross-sectional data from Wave 4 (2008–2009) of the English Longitudinal Study of Aging (ELSA) were analysed. Covariates in the model included age, sex, education, smoking status, alcohol consumption, activity level, depression and common comorbid health conditions. A total of 5341 individuals were included; mean age 65.3(±9.2) years, 55% female, 62.4% infrequent or no pain, 12.6% mild pain, 19.1% moderate pain, and 5.9% severe pain. Severe pain was associated with greater AL defined by all four formulations. The amount of variance explained by pain severity and the covariates was highest when allostatic load was defined by the high risk quartile (12.9%) and by the clinical value (11.7%). Findings indicate a positive relationship between pain severity and AL. Further investigation is needed to determine if there is a specific AL signature for pain that differs from other health conditions. PMID:27988258

AIM: To assess the long-term outcome of endoscopic hemorrhoid ligation (EHL) for the treatment of symptomatic internal hemorrhoids. METHODS: A total of 759 consecutive patients (415 males and 344 females) were enrolled. Clinical presentations were rectal bleeding (593 patients) and mucosal prolapse (166 patients). All patients received EHL at outpatient clinics. Hemorrhoid severity was classified by Goligher’s grading. The mean follow-up period was 55.4 mo (range, 45-92 mo). RESULTS: The number of band ligations averaged 2.35 in the first session for bleeding and 2.69 for prolapsed patients. Bleeding was controlled in 587 (98.0%) patients, while prolapse was reduced in 137 (82.5%) patients. After treatment, 93 patients experienced anal pain and 48 patients had mild bleeding. Patient subjective satisfaction was 93.6%. Repeat treatment or surgery was performed if symptoms were not relieved in the first session. In the bleeding group, the recurrence rate was 3.7% (22 patients) at 1 year, and 6.6% and 13.0% at 2 and 5 years. In the prolapsed group, the recurrence rate was 3.0%, 9.6% and 16.9% at 1, 2 and 5 years, respectively. CONCLUSION: EHL is an easy and well-tolerated procedure for the treatment of symptomatic internal hemorrhoids, with good long-term results. PMID:21633644

Treatment of hemorrhoids: A coloproctologist’s view

PubMed Central

Lohsiriwat, Varut

2015-01-01

Hemorrhoids is recognized as one of the most common medical conditions in general population. It is clinically characterized by painless rectal bleeding during defecation with or without prolapsing anal tissue. Generally, hemorrhoids can be divided into two types: internal hemorrhoid and external hemorrhoid. External hemorrhoid usually requires no specific treatment unless it becomes acutely thrombosed or causes patients discomfort. Meanwhile, low-graded internal hemorrhoids can be effectively treated with medication and non-operative measures (such as rubber band ligation and injection sclerotherapy). Surgery is indicated for high-graded internal hemorrhoids, or when non-operative approaches have failed, or complications have occurred. Although excisional hemorrhoidectomy remains the mainstay operation for advanced hemorrhoids and complicated hemorrhoids, several minimally invasive operations (including Ligasure hemorrhoidectomy, doppler-guided hemorrhoidal artery ligation and stapled hemorrhoidopexy) have been introduced into surgical practices in order to avoid post-hemorrhiodectomy pain. This article deals with some fundamental knowledge and current treatment of hemorrhoids in a view of a coloproctologist - which includes the management of hemorrhoids in complicated situations such as hemorrhoids in pregnancy, hemorrhoids in immunocompromised patients, hemorrhoids in patients with cirrhosis or portal hypertension, hemorrhoids in patients having antithrombotic agents, and acutely thrombosed or strangulated hemorrhoids. Future perspectives in the treatment of hemorrhoids are also discussed. PMID:26309351

Laparoscopy for inflammatory bowel disease: pros and cons.

Sardinha, T C; Wexner, S D

The role of laparoscopic surgery in the treatment of colorectal malignancies is still under investigation, although it can offer significant benefits to many patients with inflammatory bowel disease (IBD). The aim of this study was to assess the pros and cons of the laparoscopic management of IBD. Data were obtained from a review of the literature published since 1992, when the first report of laparoscopic surgery for IBD appeared in print. From 1992 to 1997 several series of laparoscopic colorectal surgery for the management of IBD have been reported. A close evaluation of these studies revealed that laparoscopy in patients with terminal ileal Crohn's disease or anal Crohn's disease in need of fecal diversion offers significant advantages compared to laparotomy, including decreased pain, length of hospitalization, and disability. An additional bonus is improved cosmesis and a reduction in symptomatic postoperative adhesions. These many benefits can be achieved without any increase in morbidity or expense. Conversely, the use of this technology for restorative proctocolectomy in patients with mucosal ulcerative colitis is associated with a longer operative time and an increased incidence of both intra- and postoperative complications compared to laparotomy. Laparoscopic colorectal surgery can thus be advantageous for treatment of terminal ileal Crohn's disease but cannot be routinely justified for the treatment of mucosal ulcerative colitis.

Although little is known about its origins, neck pain may be related to several associated anatomical pathologies. We aimed to characterize the incidence and features of chronic neck pain and analyze the relationship between neck pain severity and its affecting factors. Between March 2012 and July 2013, we studied 216 patients with chronic neck pain. Initially, combined tramadol (37.5 mg) plus acetaminophen (325 mg) was administered orally twice daily (b.i.d.) to all patients over a 2-week period. After two weeks, patients were evaluated for neck pain during an outpatient clinic visit. If the numeric rating scale of the patient had not decreased to 5 or lower, a cervical medial branch block (MBB) was recommended after double-dosed previous medication trial. We classified all patients into two groups (mild vs. severe neck pain group), based on medication efficacy. Logistic regression tests were used to evaluate the factors associated with neck pain severity. A total of 198 patients were included in the analyses, due to follow-up loss in 18 patients. While medication was successful in reducing pain in 68.2% patients with chronic neck pain, the remaining patients required cervical MBB. Lateral cervical curvature, such as a straight or sigmoid type curve, was found to be significantly associated with the severity of neck pain. We managed chronic neck pain with a simple pharmacological management protocol followed by MBB. We should keep in mind that it may be difficult to manage the patient with straight or sigmoid lateral curvature only with oral medication.

Myxopapillary ependymoma as a cause of back pain in a young male – A case report

PubMed Central

Ngo, Trung P; Dufton, John; Stern, Paula J; Islam, Omar

2013-01-01

Objective: Primary spinal cord tumours are rare causes of low back pain but can be a significant cause of morbidity if undiagnosed and untreated. The following is a case of a young male patient presenting with low back pain and radicular symptoms caused by myxopapillary ependymoma. Clinical Features: A nineteen year old male presented to an orthopaedic surgeon with a long history of back pain. He was initially diagnosed with soft tissue injuries and discharged. He began to experience erectile and bowel dysfunction two years later and was re-referred to the orthopaedic surgeon by his family physician but was lost to follow-up. The patient did not present to the surgeon until two years after his symptom profile changed. At that point, MRI examinations revealed a large myxopapillary ependymoma extending from T12 to L4 that was confirmed by a pathologist. Intervention and Outcome: The tumour was surgically resected with subsequent adjuvant radiotherapy. After one year, the patient required continued catheterization and had poor anal tone. His back and leg complaints were almost normal. Follow-up MRI examinations revealed no disease progression or new spinal lesions at 4 years after the initial diagnosis. Conclusion: The clinical presentation of primary spinal cord tumours is non-specific and can easily be missed. In cases of chronic back pain, signs and symptoms should be regularly monitored for changes indicative of progressive neurological compromise such as sensory, motor and bowel/bladder dysfunction. If there is deterioration of clinical signs and symptoms, a spinal tumour should be considered in the list of differential diagnoses. Delayed diagnosis and treatment of these rare causes of back pain could lead to poor outcomes; therefore, a referral to a surgeon should be done immediately with proper follow up to ensure continuity of care.

Hemorrhoidectomy is the most effective long-term treatment for hemorrhoids. Although it is possible to perform hemorrhoidectomy as a day case with a high degree of patient satisfaction, patients take an average of 14 days off work after surgery. Stapled hemorrhoidectomy is believed to be less painful than conventional hemorrhoidectomy and should allow an earlier return to work. The aim of this study was to compare both the immediate and the long-term results of stapled hemorrhoidectomy with diathermy hemorrhoidectomy in patients with prolapsing internal hemorrhoids in an intended day-care setting. Thirty-one patients were randomly assigned to undergo diathermy hemorrhoidectomy (n = 16) or stapled hemorrhoidectomy performed with a purpose-designed endoluminal stapling device, PPH01T (n = 15). All operations were planned as day or short-stay cases. All patients received lactulose, commenced preoperatively, together with postoperative topical glyceryl trinitrate and oral metronidazole. Patients were assessed by structured interview to assess their symptoms before and after surgery, with an intended follow-up of six months. All patients completed a 10-cm visual analog pain scale daily for the first ten days after surgery. The total pain score (sum of all pain scores) was significantly higher in the diathermy group (50 (range, 9.8-79.9) vs. 19.6 (range, 1.3-89.5), P = 0.03). Patients took a median of 14 (range, 3-21) days off work after diathermy hemorrhoidectomy compared with 10 (range, 3-38) days for the patients undergoing stapled hemorrhoidectomy (P = 0.15). At long-term follow-up, three patients (all in the stapled group) developed new symptoms of fecal urgency and anal pain, and three patients required further surgery to remove symptomatic external hemorrhoids after stapled hemorrhoidectomy. Although stapled hemorrhoidectomy is less painful in the short term, this does not lead to a significantly earlier return to work, and some patients develop new symptoms at long-term follow-up.

Objective Determine the effect of perineal lacerations on pelvic floor outcomes including urinary and anal incontinence, sexual function and perineal pain in a nulliparous cohort with low incidence of episiotomy. Methods Nulliparous women were prospectively recruited from a midwifery practice. Pelvic floor symptoms were assessed with validated questionnaires, physical examination and objective measures in pregnancy and 6 months postpartum. Two trauma groups were compared, those with an intact perineum or only 1st degree lacerations and those with 2nd, 3rd or 4th degree lacerations. Results 448 women had vaginal deliveries. 151 sustained second degree or deeper perineal trauma and 297 had an intact perineum or minor trauma. 336 (74.8%) presented for 6-month follow-up. Perineal trauma was not associated with urinary or fecal incontinence, decreased sexual activity, perineal pain, or pelvic organ prolapse. Women with trauma had similar rates of sexual activity however they had slightly lower sexual function scores (27.3 vs. 29.1, p=0.01). Objective measures of pelvic floor strength, rectal tone, urinary incontinence, and perineal anatomy were equivalent. The subgroup of women with deeper (> 2cm) perineal trauma demonstrated increased likelihood of perineal pain (15.5 vs. 6.2 %) and weaker pelvic floor muscle strength (61.0 vs. 44.3%); p=0.03 compared to women with more superficial trauma Conclusion: Women having second degree lacerations are not at increased risk for pelvic floor dysfunction other than increased pain, and slightly lower sexual function scores at 6 months postpartum.

Chronic pain is commonly co-morbid with a depressive or anxiety disorder. Objective of this study is to examine the influence of depression, along with anxiety, on pain-related disability, pain intensity, and pain location in a large sample of adults with and without a depressive and/or anxiety disorder. The study population consisted of 2981 participants with a depressive, anxiety, co-morbid depressive and anxiety disorder, remitted disorder or no current disorder (controls). Severity of depressive and anxiety symptoms was also assessed. In separate multinomial regression analyses, the association of presence of depressive or anxiety disorders and symptom severity with the Chronic Pain Grade and location of pain was explored. Presence of a depressive (OR = 6.67; P<.001), anxiety (OR = 4.84; P<.001), or co-morbid depressive and anxiety disorder (OR = 30.26; P<.001) was associated with the Chronic Pain Grade. Moreover, symptom severity was associated with more disabling and severely limiting pain. Also, a remitted depressive or anxiety disorder showed more disabling and severely limiting pain (OR = 3.53; P<.001) as compared to controls. A current anxiety disorder (OR = 2.96; p<.001) and a co-morbid depressive and anxiety disorder (OR = 5.15; P<.001) were more strongly associated with cardio-respiratory pain, than gastro-intestinal or musculoskeletal pain. These findings remain after adjustment for chronic cardio respiratory illness. Patients with a current and remitted depressive and/or anxiety disorder and those with more severe symptoms have more disabling pain and pain of cardio-respiratory nature, than persons without a depressive or anxiety disorder. This warrants further research. PMID:25330004

To examine outcomes after primary obstetric anal sphincter injuries in a subsequent pregnancy. This was a retrospective analysis of prospectively collated data from a large perinatal database between 2006 and 2010. Primiparous vaginal deliveries with an obstetric anal sphincter injury were identified and tracked to identify their subsequent delivery characteristics and perineal outcomes. A primary obstetric anal sphincter injury occurred in 5.3% of primiparous vaginal deliveries (9,857/186,239); of those patients, 2,093 had a subsequent delivery, and 91.9% delivered vaginally (1,923/2,093). The recurrent obstetric anal sphincter injury rate was also found to be 5.3% (102/1,923). The adjusted odds ratios (ORs) for primary obstetric anal sphincter injuries were significantly increased in large-for-gestational-age neonates for both third-degree laceration (adjusted OR 2.1, 95% confidence interval [CI] 1.9-2.2) and fourth-degree laceration (adjusted OR 2.7, 95% CI 2.3-3.1) and almost all obstetric interventions studied. The adjusted ORs for recurrent obstetric anal sphincter injuries were significant for large-for-gestational-age (25/102, adjusted OR 2.2, 95% CI 1.3-3.6) and instrumental deliveries (15/102, adjusted OR 2.4, 95% CI 1.2-4.6). In this study population, the incidence of recurrent obstetric anal sphincter injuries was similar to that of primary obstetric anal sphincter injuries, and most patients went on to deliver vaginally for subsequent deliveries. The risk of recurrent obstetric anal sphincter injuries was doubled in those who delivered a large-for-gestational-age neonate and in those who had an instrumental delivery.

A retrospective study of anal sac tumours without pulmonary metastases, from the author's clinical records for the period July 1989 to July 2002, was conducted to establish the response to treatment with surgery and melphalan chemotherapy. Of 21 dogs with tumours of the anal sacs 19 had apocrine gland adenocarcinomas of anal sac origin, one had a benign papillary cystadenoma and another had a malignant melanoma. Two of the 19 dogs had bilateral anal sac adenocarcinomas. Ten of the 19 dogs with apocrine gland adenocarcinomas of anal sac origin had sublumbar lymphadenopathy. Five dogs were excluded by their owners from recommended treatment. Fourteen dogs with apocrine gland adenocarcinomas of anal sac origin were treated by surgical cytoreduction and chemotherapy with melphalan. Seven of the 14 dogs had regional lymph node metastases. Cytoreduction was by local excision of the anal sac in all 14 dogs and concurrent removal of the sublumbar retroperitoneal lymph nodes in the seven dogs with regional lymph node metastases. The median survival time of dogs with sublumbar nodal metastasis was 20 months and for dogs with tumour localised to the anal sac the median survival time was 29.3 months. There was no difference in median survival of those dogs with sublumbar metastases compared to those without. This study suggests there is a role for melphalan in the treatment of dogs with anal sac adenocarcinoma when combined with cytoreductive surgery, with treatment survival times and the local recurrence rate of the primary tumour comparing favourably with previously published treatment regimes.

Prevalence estimates of anal high-risk human papillomavirus (HR-HPV) are needed in sub-Saharan Africa where HIV is endemic. This study evaluated anal HR-HPV in Nigeria among HIV-positive and HIV-negative men who have sex with men (MSM) for future immunization recommendations. We conducted a cross-sectional study to compare the prevalence of anal HR-HPV infections between 64 HIV-negative and 90 HIV-positive MSM. Multivariate Poisson regression analyses were used to examine demographic and behavioral risk factors associated with any HR-HPV infections. The median age of the 154 participants was 25 years (interquartile range, 22-28 years; range, 16-38 years), and the median age at initiation of anal sex with another man was 16 years (interquartile range, 13-18 years; range, 7-29 years). The prevalence of anal HR-HPV was higher among HIV-positive than HIV-negative MSM (91.1% vs. 40.6%, P < 0.001). In the multivariate analysis, HIV infection (adjusted prevalence ratio [aPR], 2.02; 95% confidence interval [CI], 1.49-2.72), 10 years or more since anal sexual debut (aPR, 1.26; 95% CI, 1.07-1.49), and concurrent relationships with men (aPR, 1.32; 95% CI, 1.04-1.67) were associated with increased anal HR-HPV prevalence. Anal HR-HPV infection is high for young Nigerian MSM, and rates are amplified in those coinfected with HIV. Providing universal coverage as well as catch-up immunization for young MSM may be an effective anal cancer prevention strategy in Nigeria.

Breakthrough pain (BTP) is traditionally defined as a transitory pain flare in opioid-treated patients with chronic background pain. This definition has, however, been challenged in recent years. This study aimed to analyze BTP prevalence in different pain conditions. This was a prospective, non-interventional, observational study conducted from June to September 2011 in two Italian pain treatment reference centres. Consecutive patients aged >18 years with oncological or non-oncological pain were eligible for this study; background pain was acute/ subacute (<3 months) or chronic (>3 months). The characteristics of pain were evaluated by means of a structured interview by physicians, and patients were asked to complete a dedicated clinical study form. The following outcomes were assessed: chronic pain duration (in patients with chronic pain), BTP prevalence, and number and severity of daily BTP episodes. All outcomes were assessed in four populations of patients with: (a) chronic oncological pain; (b) chronic non-oncological pain; (c) non-chronic oncological pain; (d) non-chronic non-oncological pain. The correlation between BTP and gender was also investigated. Of 1,270 patients with chronic pain, 1,086 had non-oncological pain (85.5%). Most patients (68.6%) with non-oncological pain were female (P = 0.001). Pain duration was significantly longer in non-oncological pain versus oncological pain groups (P = 0.002). BTP prevalence was lower in non-oncological patients (P < 0.001). No differences were reported in terms of number and severity of daily BTP episodes. BTP was more frequent in females with non-oncological pain (P = 0.04). Females had a significantly higher pain severity (P = 0.02) than males. BTP is frequently reported in patients who do not have BTP according to the traditional definition. BTP frequency and severity is similar in oncological and non-oncological pain.

Anal intercourse is reported by many heterosexuals, and evidence suggests that its practice may be increasing. We estimated the proportion of the HIV burden attributable to anal sex in 2015 among heterosexual women and men in the United States. The HIV Optimization and Prevention Economics model was developed using parameter inputs from the literature for the sexually active U.S. population aged 13-64. The model uses differential equations to represent the progression of the population between compartments defined by HIV disease status and continuum-of-care stages from 2007 to 2015. For heterosexual women of all ages (who do not inject drugs), almost 28% of infections were associated with anal sex, whereas for women aged 18-34, nearly 40% of HIV infections were associated with anal sex. For heterosexual men, 20% of HIV infections were associated with insertive anal sex with women. Sensitivity analyses showed that varying any of 63 inputs by ±20% resulted in no more than a 13% change in the projected number of heterosexual infections in 2015, including those attributed to anal sex. Despite uncertainties in model inputs, a substantial portion of the HIV burden among heterosexuals appears to be attributable to anal sex. Providing information about the relative risk of anal sex compared with vaginal sex may help reduce HIV incidence in heterosexuals.

Palefsky, Joel

2009-01-01

Purpose of the review The incidence of human papillomavirus (HPV)-related cancers is increased among people with HIV infection compared with the general population. This review will describe recent findings in HPV-associated cancer incidence since the introduction of antiretroviral therapy (ART), HPV/disease prevalence at sites other than cervix and anus, and recent data on screening and treatment of anal intraepithelial neoplasia (AIN). Recent findings Consistent with high prevalence of anogenital HPV infection, cervical intraepithelial neoplasia (CIN) and AIN in HIV-positive men and women, new data show that the incidence of cervical cancer has not declined since the introduction of ART and that the incidence of anal cancer is rising. Several studies also highlight high rates of HPV infection and HPV-associated disease at sites other than the cervix and anus, including the penis and mouth. Treatment methods for AIN have been described and show reasonable efficacy. Summary New data imply that the problem of HPV-related cancers will not decline among HIV-positive men and women in the ART era, highlighting the need to perform studies to determine if screening and treatment of AIN will prevent development of anal cancer. Recent data show progress in both of these areas. PMID:19339939

The anal canal is an important body part clinically. However, there is no agreement about the epithelium of the anal canal, the anal transitional zone (ATZ) epithelium in particular. The aim of this study is to clarify the structure of the epithelium of the human lower rectum and anal canal. Intact rectum and anus obtained from patients who underwent surgery for rectal carcinoma were examined by light and scanning electron microscopy (LM and SEM). By LM, three types of epithelium were observed in the anal canal: simple columnar epithelium, stratified squamous epithelium, and stratified columnar epithelium. The lower rectum was composed of simple columnar epithelium. SEM findings showed stratified squamous epithelium that consisted of squamous cells with microridges, changing to simple columnar epithelium consisting of columnar cells with short microvilli at the anorectal line. LM and SEM observations in a one-to-one ratio revealed that the area of stratified columnar epithelium based on LM corresponded to the anal crypt and sinus. In conclusion, the epithelium of the human anal canal was fundamentally composed of simple columnar epithelium and stratified squamous epithelium. We found no evidence of the ATZ.

The pathophysiology of sporadic proctalgia fugax remains unknown. This study investigates whether patients with this syndrome exhibit alterations in anal function and morphology. Eighteen patients with sporadic proctalgia fugax and 18 sex-matched and age-matched healthy controls were studied. Manometric studies investigated anal resting and squeeze pressures, the rectoanal inhibitory reflex, rectal compliance, and smooth muscle response to edrophonium chloride administration. External and internal sphincter thickness was measured endosonographically. Patients had slightly higher (P = 0.0291) anal resting pressures (65.5 +/- 11.4 mmHg) than controls (56 +/- 9.9 mmHg). However, anal squeeze pressure, sphincter relaxation during rectal distention, and rectal compliance were similar in both groups, and no alterations were detected in external and internal anal sphincter thickness. Edrophonium chloride administration was followed by sharp postrelaxation contractions in two patients, whereas anal function remained unaltered in controls. Acute episodes of proctalgia, which occurred in two patients while under study, were associated with a rise in anal resting tone and an increase in slow wave amplitude. In the resting state, patients with proctalgia fugax have normal anorectal function and morphology. However, they may exhibit a motor abnormality of the anal smooth muscle during an acute attack.

Objectives. We sought to learn what factors are associated with anal intercourse among adolescents and young adults. We examined demographic, behavioral, relationship context, attitudinal, substance use, and mental health correlates of recent heterosexual anal intercourse among adolescents and young adults who reported engaging in recent unprotected sex. Methods. Among 1348 at-risk adolescents and young adults aged 15 to 21 years in 3 US cities, we assessed sexual risk behavior with each sexual partner in the past 90 days. Data were collected from 2000 to 2001. Results. Recent heterosexual anal intercourse was reported by 16% of respondents. Females who engaged in anal intercourse were more likely to be living with a sexual partner, to have had 2 or more partners, and to have experienced coerced intercourse. For males, only a sexual orientation other than heterosexual was a significant predictor of engaging in heterosexual anal intercourse. Conclusions. Our findings document the prevalence of heterosexual anal intercourse among adolescents and young adults who had recent unprotected sex. Among females, the variables associated with anal intercourse relate to the context and power balance of sexual relationships. Different influences for males and females suggest different foci for interventions. PMID:19008522

One of the most troublesome complications of anal preserving surgery is anal sphincter dysfunction. The aim of this study was to evaluate functional recovery after implantation of adipose-derived stem cell (ADSC) sheets, novel biotechnology, for an anal sphincter resection animal model. Eighteen female Sprague-Dawley rats underwent removal of the nearest half of the internal and external anal sphincter muscle. Nine rats received transplantation with ADSC sheets to the resected area while the remaining rats received no transplantation. The rats were evaluated for the anal function by measuring their resting pressure before surgery and on postoperative days 1, 7, 14, 28, and 56. In addition, the rats were examined for the presence of smooth muscle and also to determine its origin. The improvement of the anal pressure was significantly greater in the ADSC sheet transplantation group compared with the control group. Histologically, at the vicinity of the remaining smooth muscle, reproduction of smooth muscle was detected. Using in fluorescence in situ hybridization, the cells were shown to be from the recipient. Regenerative therapy using ADSC sheet has the potential to recover anal sphincter dysfunction due to anorectal surgery. © 2017 S. Karger AG, Basel.

To evaluate the prevalence of anal intraepithelial lesions and associated risk factors in women with cervical neoplasia. The present cross-sectional study enrolled patients with intraepithelial or invasive cervical neoplasia who had been referred to the lower genital tract pathology outpatient department of the Instituto de Medicina Integral Prof. Fernando Figueira, Recife, Brazil, between December 1, 2008, and December 31, 2009; patients with HIV infections were excluded. All participants underwent anal cytology and high-resolution anoscopy; sociodemographic and clinical risk factors were identified using multivariate analysis. There were 324 patients included and 37 (11.4%) had anal intraepithelial neoplasia. Factors associated with anal intraepithelial neoplasia in the multivariate analysis were being older than 35 years of age (P=0.002), having completed no more than 4 years of education (P=0.012), anomalous anal cytology (P=0.003), and anomalous high-resolution anoscopy findings (P<0.001); subclinical HPV lesions on vulvoscopy (P=0.057) were not associated with anal intraepithelial neoplasia. The prevalence of anal intraepithelial neoplasia was high among patients with cervical neoplasia who did not have HIV, particularly patients older than 35 years. © 2017 International Federation of Gynecology and Obstetrics.

Purpose High-grade anal intraepithelial neoplasia (HGAIN) is the precursor lesion to invasive anal cancer. HPV vaccination holds great promise for preventing anal cancer. Methods We examined 235 HIV-1-infected men screening for participation in a multi-site clinical trial of a quadrivalent HPV vaccine. All participants had anal swabs obtained for HPV testing and cytology, and high resolution anoscopy with biopsies of visible lesions to assess for HGAIN. Results HPV 16 and 18 were detected in 23% and 10%, respectively; abnormal anal cytology was found in 56% and HGAIN in 30%. HGAIN prevalence was significantly higher in those with HPV 16 detection compared to those without (38% vs. 17%, P=.01). Use of antiretroviral therapy, nadir and current CD4+ cell count were not associated with abnormal anal cytology or HGAIN. Conclusion HGAIN is highly prevalent in HIV-infected men. Further studies are needed on treatment and prevention of HGAIN. PMID:23611828

Evidence for the secondary sexual development of the anal fin in female kokanee salmon Oncorhynchus nerka.

This study examines whether the anal fin undergoes secondary sexual development similar to other reproductive traits in salmonids. This hypothesis was tested by comparing the anal-fin size of female kokanee salmon Oncorhynchus nerka that were in the early and late stages of sexual development. Females in an advanced stage of maturation had significantly larger anal fins relative to females in an early state of maturation (+4-7%), indicating that the anal fin undergoes secondary sexual development. The magnitude of this secondary growth was comparable with snout length (+9-10%), which is known to undergo secondary sexual development in female salmonids. When morphological trait dimensions were compared between the sexes, the anal fin was the only morphological trait found to have a female-biased sexual size dimorphism. This is the first study to show that the anal fin of female salmonids undergoes secondary sexual development. © 2015 The Fisheries Society of the British Isles.

Using a cross-sectional survey, we examined the gender differences in prevalence of and factors associated with anal sex among adolescents attending the only public STI clinic in Singapore. Data were collected from 1035 sexually active adolescents aged 14 to 19 and analyzed using Poisson regression. Prevalence of anal intercourse was 28%, with significantly more females (32%) than males (23%) ever engaged in it. On multivariate analysis, the factors associated with anal intercourse for both genders were oral sex and the nonuse of contraception at last sex. For males, anal intercourse was associated with younger age of sexual debut and greater perceived external control. Among females, it was associated with higher rebellious scores and lack of confidence to resist peer pressure to engage in sex. Consistent condom use for anal sex was 22% and 8% for males and females, respectively. STI prevention programs for adolescents should address anal sex, be gender-specific, and take into consideration individual personality characteristics.

Diagnostic Testing for Fecal Incontinence

PubMed Central

Olson, Craig H.

2014-01-01

Many tests are available to assist in the diagnosis and management of fecal incontinence. Imaging studies such as endoanal ultrasonography and defecography provide an anatomic and functional picture of the anal canal which can be useful, especially in the setting of planned sphincter repair. Physiologic tests including anal manometry and anal acoustic reflexometry provide objective data regarding functional values of the anal canal. The value of this information is of some debate; however, as we learn more about these methods, they may prove useful in the future. Finally, nerve studies, such as pudendal motor nerve terminal latency, evaluate the function of the innervation of the anal canal. This has been shown to have significant prognostic value and can help guide clinical decision making. Significant advances have also happened in the field, with the relatively recent advent of magnetic resonance defecography and high-resolution anal manometry, which provide even greater objective anatomic and physiologic information about the anal canal and its function.

Genital warts are caused by human papillomavirus (HPV). HPV is a leading cause of anogenital malignancies and a role of HPV in the aetiology of oro-pharyngeal cancers has been demonstrated. The frequency of oral HPV infection in patients with genital warts and the association between concomitant genital, anal and oral infection is unclear. A total of 201 men and women with genital wart-like lesions were recruited. Swab samples were obtained from the genital warts and the anal canal and an oral rinse was collected. Anal HPV was found in 46.2% and oral HPV in 10.4% of the participants. Concordance between anal and genital wart HPV types was 78.1%, while concordance between oral and genital wart types was 60.9%. A lower concordance of 21.7% was observed between anal and oral HPV types. Significantly more women than men had multiple HPV types and anal HPV. In conclusion, extra genital HPV is common in patients with genital warts. A gender inequality seems to exist.

Purpose We characterized the location and spatial distribution of whole body pain among patients with urologic chronic pelvic pain syndrome (UCPPS) using a body map; and compared the severity of urinary symptoms, pelvic pain, non-pelvic pain, and psychosocial health among patients with different pain patterns. Methods 233 women and 191 men with UCPPS enrolled in a multi-center, one-year observational study completed a battery of baseline measures, including a body map describing the location of pain during the past week. Participants were categorized as having “pelvic pain only” if they reported pain in the abdomen and pelvis only. Participants who reported pain beyond the pelvis were further divided into two sub-groups based on the number of broader body regions affected by pain: an “intermediate” group (1–2 additional regions outside the pelvis) and a “widespread pain” group (3–7 additional regions). Results Of the 424 enrolled patients 25% reported pelvic pain only, and 75% reported pain beyond the pelvis of which 38% reported widespread pain. Participants with greater number of pain locations had greater non-pelvic pain severity (p<0.0001), sleep disturbance (p=0.035), depression (p=0.005), anxiety (p=0.011), psychological stress (p=0.005), negative affect scores (p=0.0004), and worse quality of life (p≤0.021). No difference in pelvic pain and urinary symptom severity were observed by increasing pain distribution. Conclusions Three-quarters of men and women with UCPPS reported pain outside the pelvis. Widespread pain was associated with greater severity of non-pelvic pain symptoms, poorer psychosocial health and worse quality of life, but not worse pelvic pain or urinary symptoms. PMID:28373134

Negative cognitions are central to the perpetuation of chronic pain and sleep disturbances. Patients with temporomandibular joint disorder (TMJD), a chronic pain condition characterized by pain and limitation in the jaw area, have a high comorbidity of sleep disturbances that possibly exacerbate their condition. Ethnic group differences are documented in pain, sleep and coping, yet the mechanisms driving these differences are still unclear, especially in clinical pain populations. 156 women (79% white, 21% African American (AA)) diagnosed with TMJD were recruited as part of a randomized controlled trial evaluating the effectiveness of interventions targeting sleep and pain catastrophizing on pain in TMJD. Analysis of baseline data demonstrated that relative to white participants, AA exhibited higher levels of clinical pain, insomnia severity and pain catastrophizing, yet there was no ethnic group difference in negative sleep-related cognitions. Mediation models revealed pain catastrophizing, but not sleep-related cognitions or insomnia severity, to be a significant single mediator of the relationship between ethnicity and clinical pain. Only the helplessness component of catastrophizing together with insomnia severity sequentially mediated the ethnicity-pain relationship. These findings identify pain catastrophizing as a potentially important link between ethnicity and clinical pain and suggest that interventions targeting pain-related helplessness could improve both sleep and pain especially for AA patients. Pain related helplessness and insomnia severity contribute to ethnic differences found in clinical pain among woman with temporomandibular joint disorder. Findings can potentially inform interventions that target insomnia and catastrophizing to assist in reducing ethnic disparities in clinical pain. Copyright © 2018. Published by Elsevier Inc.

To assess whether men who have sex with men (MSM) prefer a gel or a suppository as a delivery vehicle for a rectal microbicide. 77 HIV-negative MSM with a recent history of inconsistent condom use during receptive anal intercourse (RAI) who acknowledged being at risk of contracting HIV were enrolled in a randomised, crossover acceptability trial. They compared 35 ml placebo gel with 8 g placebo rectal suppositories used on up to three RAI occasions each. Participants preferred the gel over the suppository (75% versus 25%, p<0.001) and so did their partners (71% versus 29%, p<0.001). The gel received more favourable ratings overall and on attributes such as colour, smell, consistency, feeling in rectum immediately after insertion and/or 30 minutes after insertion and application process. The gel resulted in less negative ratings in terms of participants being bothered by leakage, soiling, bloating, gassiness, stomach cramps, urge to have bowel movement, diarrhoea, pain or trauma. Participants liked the gel more in terms of feelings during anal sex, sexual satisfaction, partners' sexual satisfaction and liking the product when condoms were used and when condoms were not used. In this sample taken from one of the populations most likely to benefit from rectal microbicide availability, gel had greater acceptability than a suppository as a potential microbicide vehicle.

The lack of data on condom and lubricant use among African men who have sex with men (MSM) hinders prevention efforts. We describe use, knowledge, and access to lubricants in Dar es Salaam and Tanga, Tanzania. Data were collected in 2012 and 2013 from a cross-sectional survey of 200 MSM in Dar es Salaam and 100 MSM in Tanga, Tanzania. The most common reason for not using condoms was dislike of condoms. Two-thirds of the men reported always using a lubricant for anal sex. Results showed that: fewer men who have sex with both men and women (MSMW) know about lubricants; more MSM look for, have difficulty finding, and find lubricants to be expensive; and MSM use lubricants to facilitate penetration. MSMW commonly receive their lubricants from their sexual partner, while MSM got them from friends and pharmacies. HIV-negative MSM used lubricants to facilitate penetration and reduce pain. HIV-positive MSM are likely to get their lubricants from pharmacies or friends. MSMW use Vaseline® significantly more than MSM as a lubricant. Results suggest that HIV prevention knowledge among MSM is greater, so HIV prevention efforts should emphasise carrying water-based lubricant among MSMW. Consequently, there is an opportunity to co-market condoms and water-based lubricants. © The Author(s) 2016.

Haemorrhoids disease is one of the most frequently occurring disabling conditions of the anorectum. We re-present the method, advantages and results of using direct current electrotherapy in the treatment of haemorrhoids. Symptomatic grades 1, 2 or 3 internal and mixed haemorroids were treated. Exposure and evaluation was with an operative proctoscope which visualized one-eighth of the anal canal at a time. All diseased segments were treated per visit, indicators of successful treatment were, darkening of the treated segment, immediate shrinking of the haemorrhoid and ceasation of popping sound of gas release at the probe tip. Patients were followed up for two weeks. No bowel preparations, medications, anesthesia nor admission was required. Four hundred and fifty six segments were exposed, 252(55.3%) were diseased. eight patients with either grades 2 or 3 diseases required two treatment visits. The most common symptom was rectal bleeding (94.7%), followed by prolapsed but manually reduced hemorrhoids (68%). Prolapse of tuft of haemorrhoidal tissue with spontaneous return was seen in 59.6%, anal pain in 29.8%, and itching in 3.5%. the median number treated segments per patient was 4. No complication was encountered. All patients treated remained symptom free at a mean duration of follow up of 16 months. Direct current electrotherapy is an effective, painless and safe out-patient treatment method for grades 1 to 3 internal and mixed hemorrhoid disease.

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. PMID:27468181

Radiographic features of lumbar disc degeneration (LDD) are common findings in patients with chronic mechanical low back pain; however, its role in disability and intensity of pain is debatable. This study aims to investigate the associations of the x-ray features of LDD and lumbar spondylolisthesis with severity of disability and intensity of pain. A cross-sectional study was conducted on 439 patients with chronic mechanical low back pain who attended the rheumatology clinic, National Hospital of Sri Lanka, Colombo, from May 2012 to May 2014. Severity of disability was measured using Modified Oswestry Disability Index and intensity of pain was assessed using numeric rating scale (0-100). X-ray features of LDD (disc space narrowing, anterior osteophytes and overall LDD) and spondylolisthesis were assessed in lateral recumbent lumbar x-rays (L1/L2 to L5/S1) and graded by a consultant radiologist blinded to clinical data. Generalised linear model with linear response was used to assess the associations of x-ray features of LDD with severity of disability and intensity of pain adjusting for age, gender, body mass index and pain radiating into legs. Mean age was 48.99 ± 11.21 and 323 (73.58%) were females. 87 (19.82%) were obese. Mean severity of disability was 30.95 ± 13.67 and mean intensity of pain was 45.50 ± 20.37. 69 (15.72%), 26 (5.92%) and 85 (19.36%) patients had grade 2 disc space narrowing, anterior osteophytes and overall LDD, respectively. 51 (11.62%) patients had lumbar spondylolisthesis. Grade of disc space narrowing and overall LDD were not associated with severity of disability or intensity of pain. The presence of lumbar spondylolisthesis was associated with severity of disability. Female gender and pain radiating into legs were associated with severity of disability and intensity of pain. Advancing age was associated with x-ray features of LDD and lumbar spondylolisthesis. Lumbar spondylolisthesis is associated with severity of disability in patients with chronic mechanical low back pain. Associations of x-ray features of LDD with severity of disability and intensity of pain are inconclusive. Female gender and pain radiating into legs are significant confounders.

To determine the accuracy of clinical diagnosis of obstetric anal sphincter injuries (OASIS) using three-dimensional (3D) endoanal ultrasound (EA-US) and to compare symptoms and anal manometry measurements between women with anal sphincters adequately repaired and those with persistent anal sphincter defects. The EA-US images of women with clinically diagnosed and repaired OASIS, defined as third- or fourth-degree perineal tear, who attended the perineal clinic at Croydon University Hospital over a 10-year period (2003-2013) were reanalyzed by a single expert blind to symptoms and the results of clinical examination. St Mark's Incontinence Scores (SMIS) and anal manometry measurements were obtained and compared between women with an intact anal sphincter and those with an anal sphincter scar and between those with an intact anal sphincter and those with a defect. Anal manometry measurements were compared between women with an external anal sphincter (EAS) defect and those with an internal anal sphincter (IAS) defect. The images of 908 women were reanalyzed. No evidence of OASIS was found in 64 (7.0%) women, an EAS scar alone was detected in 520 (57.3%) and an anal sphincter defect in 324 (35.7%). Of the 324 women with a defect, 112 had an EAS defect, 90 had an IAS defect and 122 had a combined IAS and EAS defect. SMIS results were significantly higher in women with an anal sphincter defect compared with those with no evidence of OASIS (P = 0.018), but there was no significant difference in scores between women with an intact sphincter and those with an EAS scar only. Women with a defect had a significantly lower maximum resting pressure (median (range), 44 (8-106) vs 55 (29-86) mmHg; P < 0.001) and maximum squeeze pressure (median (range), 74 (23-180) vs 103 (44-185) mmHg; P < 0.001) compared with those in the intact group. Similar, but less marked, differences were observed in women with an EAS scar compared with those who had an intact anal sphincter. The anal length was significantly shorter in women with a defect compared with those in the intact group (median (range), 20 (10-40) vs 25 (10-40) mm; P = 0.003). Seven percent of women with a clinical diagnosis of OASIS were wrongly diagnosed. We believe that this rate may differ from that of other units but training methods and competency assessment tools for the diagnosis and repair of OASIS need urgent reappraisal. The role of EA-US in the immediate postpartum period needs further evaluation as the accurate interpretation of the images is dependent on the expertise of the staff involved. Copyright © 2016 ISUOG.

This study validated the Patellofemoral Pain Severity Scale translated into Chinese. The Chinese Patellofemoral Pain Severity Scale was translated from the original English version following standard forward and backward translation procedures recommended by the International Society for Pharmacoeconomics and Outcomes Research. The survey was then conducted in clinical settings by a questionnaire comprising the Chinese Patellofemoral Pain Severity Scale, Kujala Scale and Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index. Eighty-four Chinese reading patients with patellofemoral pain were recruited from physical therapy clinics. Internal consistency of the translated instrument was measured by Cronbach alpha. Convergent validity was examined by Spearman rank correlation coefficient (rho) tests by comparing its score with the validated Chinese version of the Kujala Scale and the WOMAC Osteoarthritis Index while the test-retest reliability was evaluated by administering the questionnaires twice. Cronbach alpha values of individual questions and their overall value were above 0.85. Strong association was found between the Chinese Patellofemoral Pain Severity Scale and the Kujala Scale (rho = -0.72, p < 0.001). Moderate correlation was also found between Chinese Patellofemoral Pain Severity Scale with the WOMAC Osteoarthritis Index (rho = 0.63, p < 0.001). Excellent test-retest reliability (Intraclass correlation coefficient = 0.98) was demonstrated. The Chinese translated version of the Patellofemoral Pain Severity Scale is a reliable and valid instrument for patients with patellofemoral pain.

The association between high mechanical knee joint loading during gait with onset and progression of knee osteoarthritis has been extensively studied. However, less attention has been given to risk factors related to increased pain during gait. The purpose of this study was to evaluate knee joint moments and clinical characteristics that may be associated with gait-related knee pain in patients with knee osteoarthritis. Sixty-seven participants with knee osteoarthritis were stratified into three groups of no pain (n=18), mild pain (n=27), or moderate/severe pain (n=22) based on their self-reported symptoms during gait. All participants underwent three-dimensional gait analysis. Quadriceps strength, knee extension range of motion, radiographic knee alignment and self-reported measures of global pain and function were also quantified. The moderate/severe pain group demonstrated worse global pain (P<0.01) and physical function scores (P<0.01) compared to the no pain and the mild pain groups. The moderate/severe pain group also walked with greater knee flexion moments during the midstance phase of gait compared to the no pain group (P=0.02). Additionally, the moderate/severe pain group demonstrated greater varus knee malalignment (P=0.009), which was associated with higher weight acceptance peak knee adduction moments (P=0.003) and worse global pain (P=0.003) and physical function scores (P=0.006). Greater knee flexion moment is present during the midstance phase of gait in patients with knee osteoarthritis and moderate/severe pain during gait. Additionally, greater varus malalignment may be a sign of increased global knee joint dysfunction that can influence many activities of daily living beyond gait. Copyright © 2015 Elsevier Ltd.

Assessing pain intensity in older adults is critical and challenging. There is debate about the most effective way to ask older adults to describe their pain severity, and clinicians vary in their preferred approaches, making comparison of pain intensity scores across settings difficult. A total of 3,676 residents from 71 community nursing homes across eight states were asked about pain presence. The 1,960 residents who reported pain within the past 5 days (53% of total, 70% female; age: M = 77.9, SD = 12.4) were included in analyses. Those who reported pain were also asked to provide a rating of pain intensity using either a verbal descriptor scale (VDS; mild, moderate, severe, and very severe and horrible), a numeric rating scale (NRS; 0 = no pain to 10 = worst pain imaginable), or both. We used item response theory (IRT) methods to identify the correspondence between the VDS and the NRS response options by estimating item parameters for these and five additional pain items. The sample reported moderate amounts of pain on average. Examination of the IRT location parameters for the pain intensity items indicated the following approximate correspondence: VDS mild approximately NRS 1-4, VDS moderate approximately NRS 5-7, VDS severe approximately NRS 8-9, and VDS very severe, horrible approximately NRS 10. This IRT calibration provides a crosswalk between the two response scales so that either can be used in practice depending on the preference of the clinician and respondent.

Back pain is more prevalent in the obese, but whether back pain severity is directly correlated to obesity in veterans is unknown. We sought to determine if there was a correlation between body composition and low back pain severity in a sample of veterans. The hypothesis was that veterans with higher body mass index values would report higher low back pain severity scores. This study was a retrospective chart review of 1768 veterans presenting to a Veterans Affairs chiropractic clinic with a chief complaint of low back pain between January 1, 2009 and December 31, 2014. Spearman's rho was used to test for correlation between body composition as measured by body mass index and low back pain severity as measured by the Back Bournemouth Questionnaire. On average, the sample was predominantly male (91%), older than 50, and overweight (36.5%) or obese (48.9%). There was no correlation between body mass index and Back Bournemouth Questionnaire scores, r = .088, p < .001. The majority of veterans with low back pain in this sample were either overweight or obese. There was no correlation between body composition and low back pain severity in this sample of veterans.

HIV-positive men who have sex with men (MSM) have an increased risk for anal human papillomavirus (HPV) infection, anal high-grade intraepithelial lesions (HSIL), and anal cancer. Smoking is associated with abnormal anal cytology and with an increased risk for anal cancer. We collected 3736 intraanal swabs from 803 HIV-positive MSM who participated in an anal cancer screening program between October 2003 and August 2014. HPV prevalence, anal cytology and HPV DNA load of high-risk (HR) HPV-types 16, 18, 31 and 33 of non-smokers and smokers were compared. HPV-typing was performed by alpha-HPV genus-specific PCR and hybridization with 38 type-specific probes using a multiplex genotyping assay. In samples positive for HPV16, 18, 31, or 33, HPV DNA loads were determined by type-specific real-time PCRs and expressed as HPV DNA copies per betaglobin gene copy. At baseline, HR-HPV DNA (80.5 vs. 89.0%, p=0.001), HPV16 DNA (41.6 vs. 52.3%, p=0.003), HPV18 DNA (15.5 vs. 26.0%, p<0.001), anal dysplasia (LSIL+HSIL; 51.5 vs. 58.4%, p=0.045) and HSIL (17.2 vs. 22.7%, p=0.048) were detected more frequently in smokers compared to non-smokers. Throughout the study period 32.7% of non-smokers and 39.9% of smokers developed HSIL (p=0.011), and three smokers developed anal cancer. Considering swabs from the entire study period (median HPV load value per patient per cytology grade), smokers with normal anal cytology had significantly higher HPV16 loads (median 0.29 vs. 0.87, n=201, p=0.007) and cumulative high-risk-HPV loads (median 0.53 vs. 1.08, n=297, p=0.004) than non-smokers. Since elevated HR-HPV DNA loads are associated with an increased risk for HPV-induced anogenital cancers, HPV-infected HIV-positive MSM should be counseled to refrain from smoking. Additionally, for smokers, shorter anal cancer screening intervals than for non-smokers may be appropriate. Copyright © 2015 Elsevier GmbH. All rights reserved.
