BACKGROUND: Data regarding anal cutaneous HPV detection among HIV-positive and HIV-negative persons largely relies on studies among men who have sex with men in limited geographical settings. Understanding the distribution, determinants, and potential human health effects of anal cutaneous HPV types among men who have sex with women (MSW) is important. METHODS: Anal canal swab samples from 415 Russian MSW (384 HIV-negative and 31 HIV-positive) were tested for 43 β-HPVs and 29 γ-HPVs, using a multiplex PCR combined with Luminex technology...

BACKGROUND: Anal fissure is a linear tear in the distal anal canal resulting from persistent hypertonia and spasm of the internal sphincter which results in mucosal ischemia. We have conducted a study in order to compare the outcome of 0.2% glyceryl trinitrate cream versus 2% diltiazem cream in the treatment of chronic anal fissure. METHODS: This randomized controlled trial (RCT) was carried out in the Department of Surgical "B" unit, at Ayub Teaching Hospital, Abbottabad, Pakistan from 15th June 2012 to 15th May 2015...

We evaluated the concordance between β-HPVs detected in external genital skin, anal canal, and oral cavity specimens collected simultaneously from 717 men that were participating in the multinational HIM Study. Viral genotyping was performed using the Luminex technology. Species- and type-specific concordance was measured using kappa statistics for agreement. Overall, concordance of β-HPVs across sites was low and mainly observed among paired genital/anal canal samples. When grouped by species, solely β-4 HPVs showed moderate concordance in genital/anal pairs (κ = 0...

We report a case of perianal squamous cell carcinoma and left inguinal lymph node metastasis that showed a complete response more than 5 years after chemotherapy and concomitant proton beam therapy. A 34-year-old woman was referred to our hospital for an anal tumor and a left inguinal tumor. A digital rectal examination revealed a tumor in the anterior wall of the anal canal. In addition, the left inguinal lymph nodes were swollen, leading us to suspect metastases. Biopsy specimens confirmed poorly differentiated squamous cell carcinoma...

Introduction: Successful treatment of fistula-in-ano is sometimes challenging due to difficulty in recognising the internal opening and the course of the fistula tract. Although Goodsall’s rule was accepted in the past, as a method to determine the course of the fistula, recent data have shown conflicting results. Objectives: To study the predictive accuracy of Goodsall’s rule. Methods: A sample of 212 patients with simple fistulae were studied...

Squamous cell carcinoma of the anal canal (SCCA) is a rare HPV-associated cancer with limited sensitivity to standard chemotherapy. In a phase 2 study, nivolumab, an anti PD-1 immune checkpoint inhibitor, demonstrated significant efficacy as single-agent therapy in metastatic SCCA patients. Nevertheless, imaging assessment by standard RECIST criteria of the efficacy of immune therapy can be difficult in some patients due to tumor immune cell infiltration, and biomarkers of treatment efficacy are needed. We have previously developed a quantitative droplet digital PCR (ddPCR) technique to detect HPV circulating tumor DNA (HPV ctDNA), with excellent sensitivity and specificity...

AIMS: A proof of principle study of a novel wearable device to control neurogenic detrusor over-activity in eight male spinal cord injured subjects using conditional neuromodulation. METHODS: Transrectal stimulation was delivered through the device in response to simultaneously recorded external anal sphincter (EAS) contraction as a marker for neurogenic detrusor overactivity (NDO). The effect of conditional neuromodulation on bladder capacity and maximum detrusor pressure was investigated in addition to reliability of dyssynergic sphincter contraction as a marker for NDO...

Lateral internal sphincterotomy is used for the treatment of a chronic anal fissure. There is a lack of consensus for the amount of internal sphincter division necessary in the surgical treatment of an anal fissure. The anatomy of the anal sphincters and the subcutaneous partial sphincterotomy technique are presented with fresh anal canal specimen photographs. Lateral internal partial sphincterotomy is performed in 43 patients in the office between 2012 and 2013. The patients were questioned about their bowel habitus and any problem with anal control before the operation...

BACKGROUND: An anal fissure (AF) is a tear in the epithelial lining of the anal canal. This is a very common condition, but the choice of treatment is unclear. The use of anal dilators is effective, economic, and safe. The aim of the study was to compare the efficacy of two conservative treatments, the use of anal dilators or a finger for anal dilatation, in reducing anal pressure and resolving anal fissures. METHODS: Fifty patients with a clinical diagnosis of AF were randomly assigned to one of the treatments, self-massage of the anal sphincter (group A, 25 patients) or passive dilatation using dilators (group B, 25 patients)...

INTRODUCTION: There are few cases of synchronous rectal adenocarcinoma revealed by an anal fistula. The diagnosis of synchronous mucinous adenocarcinoma of the recto sigmoid and anal canal remains difficult. The chronic anal fistula can be mistaken as the common manifestation of a benign perianal abscess or fistula. CASE PRESENTATION: We present a rare case of a Greek Caucasian 79year old male patient with anal fistula and a recurrent perianal abscess who subsequently was found to have developed synchronous rectosigmoid and perianal mucinous adenocarcinoma on biopsy...

Inflammatory bowel disease (IBD) is characterized by recurrent or chronic inflammation of the gastrointestinal tract, which results in increased risk of developing cancer. Anorectal malignant melanoma is often misdiagnosed as either hemorrhoids or benign anorectal conditions in inflammatory bowel disease. Therefore, the overall prognosis and survival of IBD are poor. To date, the best treatment strategy remains controversial. Only early diagnosis and complete excision yield survival benefit. Here, we report a 64-year-old woman with ulcerative colitis, who was found to have anal malignant melanoma on routine colonoscopy...

BACKGROUND Dieulafoy's lesion of the anal canal is an uncommon cause of lower gastrointestinal bleeding due to rupture of a submucosal artery. This could be an under-recognized cause of hemorrhagic shock in rare cases. CASE REPORT We present 2 cases admitted with bleeding per rectum and hemorrhagic shock, and both were diagnosed as Dieulafoy's lesion of the anal canal on sigmoidoscopy. One case was treated surgically and the second was managed endoscopically. CONCLUSIONS Dieulafoy's lesion of the anal canal can be a source of massive lower gastrointestinal bleeding...

VATER association is a nonrandom occurrence of congenital malformations: vertebral defects, anal atresia, tracheoesophageal fistula, renal defects, and radial bone anomalies. We report the case of a 19-year-old man with a childhood diagnosis of VATER association, who presented to the motion sickness clinic with severe seasickness. We discuss the clinical and laboratory diagnosis of vestibular pathophysiology, which was confirmed by MRI of lateral semicircular canal and vestibule dysplasia. We suggest the possibility of vestibular involvement as part of the developmental field defect associated with VATER syndrome, which hitherto has rarely been reported...

BACKGROUND: Over the last decade, the causal link between human papillomavirus (HPV) infection and squamous cell carcinoma of the anus (SCCA) has been well described. Because HPV infection in one site is often associated with other sites of infection, it then follows that patients with SCCA may have an increased risk of additional HPV-related cancers. Identifying and targeting at-risk sites through cancer screening and surveillance may help to guide best practices. The current study sought to ascertain sites and risk of HPV-related second primary malignancies (SPMs) in survivors of SCCA...

Multimodal therapeutic strategies combining chemotherapy, radiation therapy and surgery have been shown to be feasible and to have a positive impact on outcomes by decreasing the risk of locoregional recurrence and often by increasing overall survival. The advantages of neoadjuvant chemo(radio)therapy include optimal tumor control combined with better tolerance and compliance to treatment while also increasing the number of candidates for surgery. Whereas indications for neoadjuvant therapy are increasing, its impact on surgical treatment and postoperative outcomes are not well-known...
