Abstract
Coronavirus 2019 disease (COVID-19) has created major impacts on public health. The virus has plagued a large population requiring hospitalization and resource utilization. Knowledge about the COVID-19 virus continues to grow. It can commonly present with gastrointestinal symptoms; initially, this was considered an atypical presentation, which led to delays in care. The pandemic has posed serious threats to the care of anorectal diseases. Urgent surgeries have been delayed, and the care of cancer patients and cancer screenings disrupted. This had added to patient discomfort and the adverse outcomes on healthcare will continue into the future. The better availability of personal protective equipment to providers and standard checklist protocols in operating rooms can help minimize healthcare-related spread of the virus. Telehealth, outpatient procedures, and biochemical tumor marker tests can help with mitigation of anorectal-disease-related problems. There is limited literature about the clinical management of anorectal diseases during the pandemic. We performed a detailed literature review to guide clinicians around management options for anorectal disease patients. We also highlighted the health challenges seen during the pandemic.

Abstract
The sexually transmitted enteric infections topic is one of the chapters of the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. The document was developed based on scientific evidence and validated in discussions with specialists. This article presents epidemiological and clinical aspects of these infections and guidance for service managers on their programmatic and operational management. The aim is to assist health professionals with screening, diagnosis, and treatment of people with sexually transmitted enteric infections and their sexual partners, in addition to supporting strategies for their surveillance, prevention, and control. The incidence of anorectal sexually transmitted infections has increased over the last years, mainly due to the increase in the practice of unprotected receptive anal sexual intercourse.

Abstract
Patients infected with the human immunodeficiency virus, particularly male homosexuals, are prone to develop disorders involving the anorectal and perineal structures. Cross-sectional imaging techniques, such as multidetector computed tomography with multiplanar reformations and magnetic resonance imaging performed with phased-array coils, are increasingly adopted to detect and stage infectious and neoplastic diseases, and to assess posttreatment modifications. Pyogenic perianal sepsis may be usefully investigated with imaging, particularly to assess the presence and topography of abscess collections to allow a correct surgical choice. Rectal inflammatory involvement is frequently detected during intestinal opportunistic infections, such as cytomegalovirus, pseudomembranous, and amebic colitides, including primary and secondary imaging signs consistent with proctocolitis. Anal carcinoma and intestinal lymphoma are increasingly diagnosed; therefore, special attention should be paid to the identification of solid tissue consistent with tumor; furthermore, MRI provides optimal staging and posttreatment follow-up of neoplastic lesions. Knowledge of this varied spectrum of anorectal and perineal opportunistic abnormalities and their imaging appearances should help radiologists to propose appropriate differential diagnoses, suggest correlation with laboratory and microbiological assays or biopsy, and reliably assess therapeutic response.

Abstract
Rectal syphilis, known as a great masquerader, can be difficult to diagnose because of its variable symptoms. Gastroenterologists should be aware of the possibility of rectal syphilis when confronted with anorectal ulcers, and should gather a detailed history about sexual preferences and practices, including homosexuality. We report a case of primary rectal syphilis mimicking rectal cancer on radiologic imaging. In this report, we described the clinical, endoscopic, and radiologic features of this rare case.

Abstract
The gastrointestinal mucosa is a target of many sexually transmitted infections, and major advances have increased our understanding of the consequences of such infections within the gastrointestinal system. HIV-1 is associated with a marked loss of mucosal CD4(+) T cells that express CC-chemokine receptor 5. This process seems to be more rapid and more severe in mucosa-associated lymphoid tissue than in the peripheral blood. Mechanistic insights into the underlying cause of acute and chronic gastrointestinal damage with HIV infection-microbial translocation, defects in intestinal epithelial barrier function and activation of a systemic immune response-have also been achieved. Increased understanding of the pathogenesis of mucosal HIV-1 infection may identify therapeutic targets to restore immunological function and the integrity of the intestinal mucosal epithelial barrier. The increasing prevalence of lymphogranuloma venereum in Europe, mostly in HIV-positive men who have sex with men, suggests a change in the epidemiology of what was previously considered to be a 'tropical' disease. The increasing incidence of acute HCV infection transmitted via sexual contact has also been fueled by high-risk sexual behaviors among men who have sex with men, many of whom are also HIV-positive. The first part of this Review discusses the pathogenesis and gastrointestinal complications of HIV infection, and the second part summarizes advances in our understanding of other sexually transmitted infections of the gastrointestinal system.

Abstract
The large intestinal mucosa contains immunological structures that may potentially serve as a site for induction of mucosal immunity against infections. Adenovirus (Ad), which is effective in gene transfer to epithelia, may be an ideal antigen delivery system for vaccination at the large intestinal mucosa. To investigate this potential, we immunized mice with recombinant replication-deficient Ad through a single intracolorectal (ICR) administration. Effective transfer of encoded genes was found in both the epithelial layer and lamina propria of the colorectal mucosa. Dendritic cells were able to transfer antigen to the draining lymph nodes, where antigen-specific CD8(+) T cells were primed. Functional antigen-specific CD8(+) T cells and IgA-specific antibodies were detected during the effector phase in the large intestine. Compared to other immunization routes (intranasal, subcutaneous), ICR immunization induced stronger colorectal immune responses and more potent protection against rectal challenge with pathogenic viruses. Further, this immunization strategy provided vaginal protection, more potent than that induced by vaccination in the nose or skin. Therefore, large intestine mucosal immunization using Ad represents an effective vaccination strategy against virus infection at both rectal and vaginal mucosal tissue sites.

Abstract
INTRODUCTION Anal fissure is a common and distressing problem the true incidence of which is probably higher than recorded. There is a progressive understanding of the etiopathogenesis of this entity and the changing trend in its management approach. This is a systematic review of available published literature looking at current management options in anal fissures. METHODS A MEDLINE-based search of the relevant literature from 1970 to 2004 was performed on the current concepts in etiopathogenesis and management of anal fissure. RESULTS The current opinion is a drift toward conservative measures as the first- and second-line approaches rather than surgery for treatment of anal fissure. Simple and readily available measures with less complication, good patient compliance, and satisfaction requiring no hospitalization should first be considered. CONCLUSIONS Most anal fissures heal with medical therapy, but their limitations include side effects, poor compliance, and recurrence of the fissure. A cautious surgical approach is required to treat those who do not respond to medical therapy.

Abstract
The incidence of syphilis, an infectious disease caused by Treponema pallidum, is low worldwide. The knowledge of its symptoms is however important, since the infectivity is high and therapy is comparatively easy. The first feature of an infection is the chancre, which is nearly always located in the genital region. In half of the infected patients after 8-12 weeks, if untreated, a generalisation takes place, during which the bacteria affect all organ systems. At first the skin diseases are most prominent; in long-term disease (late syphilis) symptoms of the central nervous system and the cardiovascular system become more relevant. In the chancre the infectious agent may be proven natively, but not in a culture. At about 3-6 weeks after infection specific serum antibodies may be proven with very sensitive and specific methods. Mainly the TPHA and FTA tests are used. These tests allow a reliable diagnosis to be made also in cases with ambiguous clinical features. The treatment of syphilis is performed by using parenteral depot penicillins for 14 days. It may also be applied as post-exposure prophylaxis. Specifics of the course have to be take into consideration in cases of coexisting HIV infections and neurosyphilis. The disease has a favourable prognosis, when treatment starts early enough.

Abstract
The global increase in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and sexually transmitted infections (STIs) has led to the introduction of barrier methods, such as condoms. However, drawbacks associated with condoms, such as men being reluctant to use them and women being unable to negotiate their use, have led to the search for better and acceptable alternatives, namely the microbicides. These are gel formulations that, when used prior to sexual intercourse, protect against the transmission of HIV and other STIs. However, after observing the side-effects of nonoxynol-9, a component of the microbicidal formulations available on the market, the focus has shifted to natural available compounds demonstrating the preferred protective effects. Antimicrobial peptides (AMPs) are one such group of compounds present in a wide range of organisms from bacteria to humans. The existing 750 or so, low-molecular-weight, cationic charged peptides are classified into five major groups based on their three-dimensional structure obtained by nuclear magnetic resonance studies. The hypothesized mode of action seems to be the interaction of the positively charged peptides with the negatively charged phospholipids present on the surface of the cell membrane. Various studies have demonstrated the effect of several AMPs, namely, defensins, protegrins, cathelicidins, cecropins, polyphemusins, magainins and melittins, against various STI-causing pathogens and HIV/herpes simplex virus, both in vitro and in vivo. The contraceptive efficacies of magainin and nisin in vitro and in vivo are worth mentioning. We believe these peptides are suitable candidates in the development of newer mechanism-based microbicides in future.

Abstract
BACKGROUND Cryptosporidiosis, caused by Cryptosporidium, is an enteric illness that has received much attention as an infection of immunocompromised persons as well as in community outbreaks (frequently waterborne). There are, however, no studies of the risk factors for sporadic community-acquired cryptosporidiosis in the immunocompetent US population. We undertook a case-control study in the San Francisco Bay Area as part of a national study sponsored by the Centers for Disease Control and Prevention to ascertain the major routes of transmission for endemic cryptosporidiosis, with an emphasis on evaluating risk from drinking water. METHODS Cases were recruited from a population-based, active surveillance system and age-matched controls were recruited using sequential random-digit dialing. Cases (n = 26) and controls (n = 62) were interviewed by telephone using a standardized questionnaire that included information about the following exposures: drinking water, recreational water, food items, travel, animal contact, and person-to-person fecal contact, and (for adults) sexual practices. RESULTS In multivariate conditional logistic regression analyses no significant association with drinking water was detected. The major risk factor for cryptosporidiosis in the San Francisco Bay Area was travel to another country (matched odds ratio [95% confidence interval]: 24.1 [2.6, 220]). CONCLUSION The results of this study do not support the hypothesis that drinking water is an independent risk factor for cryptosporidiosis among the immunocompetent population. These findings should be used to design larger studies of endemic cryptosporidiosis to elucidate the precise mechanisms of transmission, whether waterborne or other.

Abstract
BACKGROUND Efforts to develop topical microbicide products have all but ignored evaluation for rectal use. GOAL The goal of this study was to assess the effects of multiple rectal applications of Conceptrol (containing 4% nonoxynol-9) on flora and mucosal tissues in the pig-tailed macaque model. STUDY DESIGN Monkeys (8 per group) received daily rectal applications of Conceptrol, placebo gel, or no product, for 3 days. At each visit, a preapplication rectal lavage specimen and swab specimen for microbiology and pH determination were collected. Conceptrol or placebo gel (2.5 ml) was then administered intrarectally. Fifteen minutes after application, samples were again collected. RESULTS Gross observation of rectal lavage indicated sheets of epithelium 15 minutes after application of the nonoxynol-9 product. Histopathology of these samples revealed epithelial sheets with stroma attached. The presence of H(2)O(2)-producing lactobacilli remained relatively constant, whereas that of H(2)O(2)-producing viridans streptococci diminished in all nonoxynol-9-exposed animals in which these organisms were detected at baseline. CONCLUSIONS Repeated applications of nonoxynol-9 disrupts the rectal mucosa of the pig-tailed macaque. The disruption of these tissues could have serious implications for an increase in likelihood of acquisition of sexually transmitted infection/HIV in humans.

Abstract
Topically applied microbicides that eradicate pathogens at the time of initial exposure represent a powerful strategy for the prevention of sexually transmitted infections. To aid in the further development of an effective topical microbicide, we assessed the minimum cidal concentration (MCC) of two cecropin peptides, D2A21 and D4E1, and gel formulations containing 0.1 to 2% D2A21 against Chlamydia trachomatis in vitro. The MCC of peptide D2A21 was 5 microM (18.32 microg/ml), and that of peptide D4E1 was 7.5 microM (21.69 microg/ml). The MCC of gel formulations containing 2% D2A21 was 0.2 mM (0.7 mg/ml), and that of gel formulations containing 0.5% D2A21 was 0.2 mM (0.7 mg/ml). There was no significant variation in the results when two different C. trachomatis strains were tested, and the addition of 10% human blood did not significantly alter the MCCs. pH values above and below 7 reduced the activity of the D2A21 peptide alone, but the MCC of the 2% D2A21 gel formulation was only slightly altered at the various pHs tested. Ultrastructural studies indicated that C. trachomatis membranes were disrupted after D2A21 exposure, resulting in leakage of the cytoplasmic contents. These in vitro results suggest that these cecropin peptides may be an effective topical microbicide against C. trachomatis and support the need for further evaluation.

Abstract
BACKGROUND A topical microbicide should protect against acquisition of sexually transmitted infection during both vaginal and rectal intercourse. The rectal microflora of the Macaca nemestrina (pig-tailed macaque) and humans were examined, as well as the histopathology of rectal tissues. In a subset of macaques, a human rectal isolate of Chlamydia trachomatis was inoculated into the rectum to establish rectal chlamydial infection. GOAL To evaluate the comparability of the pig-tailed macaque rectal model with humans. STUDY DESIGN Rectal swabs were collected for microbiologic analysis to characterize normal microflora in pig-tailed macaques and humans. Subsequently, 10 macaques received a rectal inoculation with C trachomatis, serovar D, prepared from a clinical rectal isolate. RESULTS The rectal microflora of pig-tailed macaques (n = 80) were found to be comparable with the rectal flora of humans (n = 40). The prevalence of Lactobacillus in the rectum was higher in the macaques than in humans. Coliform and Enterococcus were decreased in the macaques, as compared with those of humans. In 9 of 10 macaques, rectal chlamydial infection was confirmed by culture or ligase chain reaction on days 2, 7, and 14 after inoculation. The test results were positive for rectal chlamydial infection by ligase chain reaction only for the remaining animal on day 14 after inoculation. CONCLUSIONS The findings demonstrate that the rectal environment of the pig-tailed macaque is a useful model for further evaluation of newly developed topical microbicides for rectal use. Furthermore, such products can be evaluated for protection against rectal chlamydial infection in this model.

Abstract
PURPOSE Patients with acquired immunodeficiency syndrome are often in poor general physical condition. Diarrhea and bleeding hemorrhoids frequently contribute to the morbidity, and patients with such problems cause an increasing load on many outpatient clinics. METHODS Twenty-two patients (17 males) with acquired immunodeficiency syndrome had injection treatment for bleeding second-degree to fourth-degree hemorrhoids according to standard outpatient clinic routines. Mean follow-up was 24 months. RESULTS No complications were recorded. The treatment was successful in all patients, and no hemorrhoidectomy was necessary. Nineteen patients improved after their first injection, whereas 3 patients required two to six weeks repeated treatments to improve. Four subjects with the longer follow-up (4 years) showed an improvement lasting 12 to 18 months and then required one to two treatments per year to stop recurrent bleeding. CONCLUSIONS Because of their poor general condition and poor wound healing, a conservative approach is preferable to avoid a formal hemorrhoidectomy in patients with acquired immunodeficiency syndrome. Sclerotherapy seems to be an attractive alternative.

Abstract
Sexually transmitted diseases (STDs) occur commonly in sexually active human immunodeficiency virus (HIV)-positive men. STDs may have atypical presentations, can cause significant morbidity in persons with HIV infection, and may increase the risk of HIV transmission. Thus, the appropriate diagnosis and treatment of STDs in this population are extremely important. The clinical manifestations and treatment of several common STDs in HIV-positive men are reviewed. Further research is needed to define effective management and screening strategies for STDs in men with HIV infection.

Abstract
Sexually transmitted diseases (STDs) are the cause of many different anorectal symptoms and complaints. Patients often present concerned that they have hemorrhoids. It is very important for primary care providers to be aware of the prevalance of anorectal STDs, common presentations, and management options. This article specifically addresses anal warts, gonorrhea, chlamydia, syphilis, herpes, and anorectal manifestations associated with HIV.

Abstract
A systematic approach to the patient with anorectal complaints allows for an accurate and efficient diagnosis of the underlying problem. The process can be divided into the interview, the examination, treatment, and conveyance of information. Throughout this process, the patient must be reassured and made as comfortable as possible. A successful interaction with the patient leads to a diagnosis and a treatment plan that is acceptable to both the physician and the patient.

Abstract
PURPOSE Anorectal diseases are common in human immunodeficiency virus-infected individuals. The aim of this prospective study was to assess the cause and clinical presentation of anorectal disease in this human immunodeficiency virus-infected population. METHODS A registry of all human immunodeficiency virus-seropositive patients with anorectal complaints who were referred to and followed up in the colorectal surgery clinic at a county hospital was maintained, with all data collected prospectively. All patients underwent examination under anesthesia with random cultures and biopsies, along with specific sampling of any suspicious lesions. RESULTS Data from 180 consecutive human immunodeficiency virus-seropositive patients with anorectal symptoms were analyzed. Mean age of the population was 34 years, with a male-to-female ratio of 14:1. This group comprised homosexual and bisexual males (55 percent), injection-drug users (15 percent), heterosexuals (12 percent), and others (18 percent). The average lag time from diagnosis of human immunodeficiency virus to anorectal symptoms was 48 months. The average CD4 lymphocyte count was 160 cells/mm3. The most common symptom was anorectal pain (57 percent), followed by lumps or warts (28 percent), rectal bleeding (12 percent), discharge (11 percent), and pruritus (6 percent), with 24 percent of patients having multiple complaints. Anal condyloma was the most prevalent pathology observed (43 percent), of which 10 percent was associated with anal intraepithelial neoplasia. Wide-based anal ulcers were the most frequent noncondylomatous lesions, occurring in 32 percent of patients, with the majority (91 percent) presenting with the chief complaint of anorectal pain. Some of these ulcers were associated with viral infections: herpes simplex virus (12 percent) and cytomegalovirus (7 percent). However, most ulcers were idiopathic, with negative cultures and biopsies. Other lesions encountered included fistulas (14 percent), abscesses (12 percent), hemorrhoids (6 percent), and malignancy, with two cases of Kaposi's sarcoma, one case of non-Hodgkin's lymphoma, and one case of squamous-cell carcinoma. More than one anorectal condition was identified in 16 percent of the patients. CONCLUSIONS Human immunodeficiency virus infection is associated with a wide spectrum of anorectal disease, of which the most common lesions are anal condylomata and painful ulcers. The majority of these anal ulcers gave negative culture and biopsy results. In addition, there seems to be a high incidence of anorectal neoplasia in this patient population.

Abstract
PURPOSE Individuals infected with the human immunodeficiency virus often have disorders affecting the anorectum. These disorders may be complex and difficult to treat. We reported our early experience with 40 human immunodeficiency virus-positive patients with perianal disorders in 1990. We now present our series of 260 consecutive human immunodeficiency virus-positive patients with perianal disorders who underwent evaluation between 1989 and 1996 to examine the distribution of disorders, their treatments, and outcomes. METHOD Patients were identified at initial presentation and followed prospectively. RESULTS Two-hundred forty-nine (96 percent) of 260 patients were male, with an average age of 34.9 (range, 19-58) years. Average duration of human immunodeficiency virus positivity was 5 years, 5 months, with a maximum of 11 years, 5 months. Median CD4 count was 175 (range, 2-1,100) cells/mm3. Only 89 (34 percent) patients satisfied the criteria of the Centers for Disease Control and Prevention's for acquired immunodeficiency syndrome at presentation. The most frequent major presenting symptoms were anorectal pain (55 percent), a mass (19 percent), and blood in the stool (16 percent). Risk factors included homosexuality (75 percent) and a prior history of sexually transmitted disease (45 percent). Forty different perianal disorders were identified, which were categorized as benign noninfectious (18), infectious (14), neoplastic (6), and septic (2). The most common disorders were condyloma (42 percent), fistula (34 percent), fissure (32 percent), and abscess (25 percent). Neoplasms were present in 19 patients (7 percent). One hundred seventy-one patients (66 percent) had more than one disorder, with an average of 2.9 disorders among these patients. Four hundred eighty-five procedures were performed on 178 patients (2.7/patient), with no mortalities and a 2 percent complication rate. Thirty-one patients (12 percent) died during the course of follow-up, but anorectal disease was the cause of death in only two patients. CONCLUSIONS Perianal manifestations of human immunodeficiency virus infection are common, often multiple, and varied. Patients with perianal disorders seek treatment throughout the course of the human immunodeficiency virus infection, and a perianal condition may be this disease's initial manifestation. Although recurrence is common and healing delayed, improved overall management of human immunodeficiency virus infection and a healthier human immunodeficiency virus-positive patient population have improved the outcome of surgical intervention in human immunodeficiency virus-infected patients with perianal disorders.

Abstract
Specific pathologic processes, particularly oral, esophageal, and intestinal infections, are common in the alimentary tract of AIDS patients. Many of these diseases are adequately assessed only by biopsy with histologic examination. Most are rare or unreported in immunocompetent hosts and are easily missed by those not familiar with them. This article describes the gross or endoscopic and histologic appearances and the diagnostic criteria for enteric pathologic processes seen in HIV-infected individuals.

Abstract
Anorectal disorders are commonly encountered in the practice of emergency medicine. Most can be diagnosed and treated in the emergency department setting. Almost all anorectal disorders once diagnosed and treated in the emergency department need appropriate follow-up to ensure adequacy of treatment, for further possible diagnostic procedures (e.g., endoscopy, biopsy), or for definitive treatment. Hemorrhoids are the most prevalent anorectal disorder and are the most common cause of hematochezia. Treatment is dependent on the degree of hemorrhoid prolapse and symptoms. Most cases can be treated by conservative medical treatment (e.g., dietary changes, sitz baths) or nonsurgical procedures (e.g., rubber band liagation, infrared coagulation). Surgical excision of symptomatic thrombosed external hemorrhoids is indicated if within 48 to 72 hours of pain onset. Anal fissures are one of the most common causes of anorectal pain. They are most frequently idiopathic, and most are located in the posterior midline of the anal canal. Most anal fissures are adequately treated by a medical approach using sitz baths, stool softeners, and analgesics. If the anal fissure becomes chronic and is not responsive to medical therapy, a lateral sphincterotomy of the internal anal sphincter is the surgical procedure of choice. Pharmacologic treatment (botulinum toxin or nitroglycerin ointment) to decrease internal anal sphincter tone has shown promise in the treatment of anal fissure. Anorectal abscesses are categorized into four types: perianal, ischiorectal, intersphincteric, and supralevator. Most are idiopathic and contain mixed aerobic-anaerobic pathogens. Fistula formation varies from 25% to 50% and is much more common with gut-derived organisms (e.g., E. coli, B. fragilis). Definitive treatment for an anorectal abscess is timely surgical incision and drainage to prevent more serious complications (e.g., serious infection, extension of the abscess). Anal carcinomas are infrequent, the majority of them being squamous cell or epidermoid carcinomas. The emergency physician must maintain a high index of suspicion and obtain a biopsy of suspicious lesions in order not to miss the diagnosis of a cancer. The most common presenting complaint of anal tumors is rectal bleeding. Combination chemotherapy and radiotherapy have shown promising results in the treatment of anal canal tumors. Bacterial, viral, and protozoal infections can be transmitted to the anorectum via anoreceptive intercourse. Such infections must be considered when a patient presents with rectal pain or discharge, tenesmus, or rectal or perineal ulcers. Proctosigmoidoscopy and rectal cultures may be necessary to determine the cause. Potential rectal complications of HIV infection include infectious diarrhea, acyclovir-resistant strains of HSV2, Kaposi's sarcoma, lymphoma, and squamous cell carcinoma. Rectal injuries may result from penetrating or blunt trauma, iatrogenic injuries, or foreign bodies. Rectal injury should be suspected when a patient presents with low abdominal, pelvic, or perineal pain or blood per rectum after sustaining trauma or undergoing an endoscopic or surgical procedure. Tetanus prophylaxis, intravenous antibiotics, and surgical intervention are indicated in all but superficial rectal tears.

Abstract
Fifty human immunodeficiency virus (HIV)-infected patients with perianal sepsis were studied. Seven (14 per cent) had serious septic complications, four patients with severe necrotizing gangrene, and three with abscesses in the mediastinum, liver and brain respectively. CD4+ lymphocyte counts were significantly lower in patients with severe septic complications as compared with those with uncomplicated perianal sepsis (P < 0.05). In patients with HIV presenting with rare (metastatic) abscesses, perianal sepsis must always be kept in mind as a possible focus. Although HIV-infected patients have a limited life expectancy perianal fistulas and abscesses should be aggressively treated, because of the high risk of severe complications.

Abstract
PURPOSE Anorectal disease is commonly found in human immunodeficiency virus (HIV)-infected patients. The aim of this study was to determine the spectrum of anorectal disease, its surgical treatment, clinical outcome, and its relation to immune status. METHODS Medical records of all HIV-infected patients with anorectal pathology that required surgical treatment from January 1984 to January 1994 were retrospectively reviewed. Patients were divided into five different groups: common anorectal pathology (hemorrhoids, polyps, Group A); condylomata acuminata (Group B); perianal sepsis (abscesses, fistulas, Group C); anorectal ulcers (Group D); malignancies (Group E). RESULTS Eighty-three patients needed 204 surgical consultations (13 percent conservative, 87 percent operative) for 170 anorectal diseases. Fifty-one patients had multiple anorectal pathology. Operative intervention resulted in adequate wound healing and symptom relief in 59 percent of patients, adequate wound healing without relief of symptoms in 24 percent of patients, and disturbed wound healing was related to type of anorectal disease (P < 0.001) and to preoperative CD4(+)-lymphocyte counts (P < 0.01). Disturbed wound healing and most insufficient immune status were encountered in Groups C, D, and E. Within these groups low CD4(+)-lymphocyte counts were a risk factor for disturbed wound healing (P = 0.004). Median postoperative survival was highest (4.7 years) in Group A, lowest (0.6 years) in Groups D and E, and related to type of anorectal disease (P = 0.0001). CONCLUSIONS The spectrum of anorectal disease is complex. Type of anorectal disease is strongly related to immune status, wound healing, and postoperative survival.

Abstract
Anorectal manifestations are commonplace in patients with HIV infection. However, standardized or rational treatment of these conditions has not been proposed and many patients are denied adequate treatment based on fear of complications. This review looks critically at the available literature to draw conclusions about treatment, results and complications of surgery for anorectal problems in these patients.

Abstract
In patients infected with human immunodeficiency virus (HIV) no effective surgical procedure has been described for anorectal ulceration that is resistant to medical therapy. This study was designed to determine the effectiveness of surgical excision of anorectal ulcers, with or without mucosal advancement. The medical records of patients with HIV and anorectal pathology diagnosed between 1984 and 1994 were reviewed. Patients with anorectal ulcers were divided into group A which was treated only with excision and group B in which excision was combined with mucosal advancement. Surgical treatment was considered successful if relief of symptoms was achieved within 4 weeks of the operation. Excision of anorectal ulcers was successful in seven of 16 patients (44 per cent) in group A. Relief of symptoms was achieved in 12 of 13 patients (92 per cent) in group B when surgical excision was combined with mucosal advancement, which is significantly better than the results in group A (P = 0.02). This non-randomized study indicates that after unsuccessful medical treatment persistent symptomatic ulcers should be treated operatively by excision with mucosal advancement.

Abstract
During the past 20 years, there has been an increased use of the anorectum for erotic pleasure. Consequently, this has led to an overwhelming rise in sexually transmitted diseases (STDs) of the anus and rectum. It is important that surgeons involved with the care of colon and rectal disorders be familiar with each of these diseases. The recent AIDS epidemic has been a challenge to the medical community. Equally as challenging is the management of common anorectal disorders in the AIDS patient. AIDS not only influences the manner in which STDs present but is associated with its own spectrum of anorectal disorders. Discussion and management of STDs and anorectal disorders of AIDS patients are presented.

Abstract
Four distinct disease processes account for the majority of surgically correctable intra-abdominal pathologies associated with human immunodeficiency virus (HIV) infection: cytomegalovirus infection, Kaposi's sarcoma, non-Hodgkin's lymphoma and mycobacterial infection. Affected patients may also develop acute cholecystitis and appendicitis with significant frequency. Thorough investigation, when possible, will obviate the need for laparotomy in most HIV-infected patients with abdominal symptoms and signs. In those who require surgical intervention, the outcome varies greatly according to the nature of the diagnosis.

Abstract
PURPOSE Individuals who are seropositive for the human immunodeficiency virus are at high risk for opportunistic infection and anorectal disorders. Little prospective information is available regarding anorectal pathogens in these patients. METHODS One hundred sixty-three HIV-seropositive patients presented to the colorectal clinic between 1989 and 1992. Forty-seven (29 percent) patients were thought to have an infectious process and were prospectively studied using a standardized multiculture protocol. RESULTS Mean age was 33 (range, 19-59) years. All were male; high-risk behavior accounted for 87 percent of HIV transmissions. Presenting complaints included anorectal pain (79 percent), pus per anum (28 percent), and blood per anum (26 percent). Examination revealed perianal tenderness (60 percent), condyloma (38 percent), perianal ulcers (38 percent), and anal fissures (34 percent). Sixty-six sets of cultures were performed; 28 patients had one set, 15 had two sets, and 4 had three sets. Thirty-two of these 47 patients (68 percent) had positive cultures including herpes (50 percent), cytomegalovirus (25 percent), Neisseria gonorrhoeae (16 percent), chlamydia (16 percent), acidfast bacilli (2 percent), and others (9 percent). Six of 32 patients with positive cultures had more than one organism cultured. Sixteen (50 percent) patients with positive cultures were treated medically, 8 (25 percent) were treated surgically and 8 (25 percent) were treated with both modalities. Sixty-one procedures were performed on 17 patients for condylomata. Eighteen patients had 20 procedures for abscesses, 50 percent of whom had positive cultures for other than common bowel flora; all improved. Fourteen patients underwent 33 procedures for perianal fistulas. Mycobacterium fortuitum was cultured from one patient who required 13 procedures for abscesses and fistulas. Forty-five (96 percent) patients were followed for an average of 12.5 months +/- 2.9 SEM (range, 1-94 months). Symptoms were improved or resolved in 22 of 32 (69 percent) patients with positive cultures and in 11 of 13 (84 percent) with negative cultures. CONCLUSIONS Specific pathogens may often be identified in human immunodeficiency virus-seropositive patients with anorectal disorders if aggressively sought. Although patients without specific pathogens identified may be expected to improve with planned empiric treatment, positive identification allows more directed therapy.

Abstract
PURPOSE The aim of this study was to describe our experiences of surgical removal of inflamed bowel in cytomegalovirus enterocolitis. METHODS Eight homosexual males with a mean age of 41 years (range, 29-59 years) and a mean CD4 count of 21 x 10(6)/l (1-60 x 10(6)/l) with advanced human immunodeficiency virus infection and severe cytomegalovirus enterocolitis were treated with ileocecal resection (4 patients) or right-sided hemicolectomy (4 patients). Symptoms were lower abdominal pain, severe diarrhea, fever, and weight loss, unrelieved by anticytomegalovirus therapy. Radiologic examination showed that ulcerative inflammation was limited to the right colon and terminal ileum. Microscopic examination confirmed the cytomegalovirus enterocolitis. Intermittent cytomegalovirus treatment, usually with foscarnet for 10 to 14 days every 4 to 6 weeks was given postoperatively. RESULTS Two minor postoperative complications occurred: a lesser wound infection and a moderate bleeding from the abdominal wound edges. One patient died after three weeks because of gastrointestinal bleeding from an ulcerating Kaposi's sarcoma lesion and another patient died from unrelated causes three weeks after discharge from the hospital. The remaining 6 patients experienced complete or partial palliation of the abdominal symptoms for a mean of 14 months (range, 5-35 months) until death or the end of observation time. One patient is still alive two years after the operation. The overall mean survival was 12 months (range, 0.5-35 months). Recurrent or persistent symptoms and/or signs of cytomegalovirus enterocolitis occurred in four patients after a mean of seven months. CONCLUSION Resection of inflamed bowel combined with postoperative anticytomegalovirus treatment leads to excellent palliation and a relatively favorable survival in AIDS patients with cytomegalovirus enterocolitis.

Abstract
Cytomegaloviruses (CMV) commonly infect man but overt disease only occurs in few patients; in the vast majority the infection is subclinical. We report on a HIV-negative pregnant woman. She suffered from a life-threatening ulcerating colitis due to CMV infection for which laparotomy was indicated. The case history is presented and suggestions are given for the surgical treatment of gastrointestinal complications such as haemorrhage, toxic colitis and perforation. Although CMV disease usually occurs in immunocompromised patients such as AIDS patients and transplant recipients, one should always keep the possibility of CMV infection in mind. The gastrointestinal tract is one of the sites of infection where the colon and terminal ileum are most frequently involved in complications such as bleeding and perforation. Gastrointestinal complications of CMV infection, although rare, can be life threatening and often require extensive surgery.

Abstract
In a prospective study, we analysed the anorectal lesions observed in 148 human immunodeficiency virus-infected patients and compared the data with those reported in the literature. The majority of the patients (97.3%) were homosexual or bisexual men. The mean age of the population was 34.2 years. A history of previous sexually transmitted diseases was found in 79.7% of the male patients. The stage of HIV-related disease, according to the Centers for Disease Control classification, could be determined in 141 patients: 54.6% were stage II, 3.5% stage III and 41.8% stage IV. Anal condylomata were the most frequent manifestation, affecting 29.7% of the patients, 7.1% of whom showed moderate to severe dysplasia. The types were mainly 6, 11, 16 and 18, but types 31, 35 and 39 were also observed. Ulcerations were the most frequent non-condylomatous lesions, occurring in 41 patients; most (60%) were due to herpes viruses, and a large minority (21%) to cytomegalovirus. The etiology could not be determined in five cases. Anal sepsis was present in 11.4%, haemorrhoidal disease in 16.8% and fissures in 6%. Six patients developed Kaposi's sarcoma and seven, non-Hodgkin's lymphoma. No anal cancers were observed. Finally, wound healing was slowed in the patients operated on for haemorrhoids, fissures and suppuration. No statistical analysis could be performed because of the small number of patients.

Abstract
The charts of all patients with the acquired immune deficiency syndrome (AIDS) who underwent emergency intra-abdominal surgery between January 1981 and July 1987 were reviewed. Eleven AIDS patients underwent 13 emergency laparotomies. Seven of these patients (64 percent) had cytomegalovirus (CMV) ileocolitis as the pathologic process requiring emergent surgical intervention. Four patients had hemorrhagic CMV proctocolitis and three had perforations of CMV ulcers of the ileum or rectosigmoid. The operations performed included three subtotal colectomies, two segmental resections, and two diverting stomas. The postoperative mortality rate in the CMV group was 28 percent at one day, 71 percent at one month, and 86 percent at six months. Furthermore, CMV ileocolonic pathology was directly responsible for 70 percent of the deaths in AIDS patients who underwent emergent exploratory laparotomy.
