Abstract
Anorectal infections in neutropenic leukemia patients are a significant and potentially life-threatening complication. The pathogenesis of this condition is not entirely understood and believed to be multifactorial, including mucosal injury as a result of cytotoxic drugs, profound neutropenia and impaired host defense. Establishing an early diagnosis is key and often made clinically on the basis of signs and symptoms, but also from imaging studies demonstrating perianal inflammation or fluid collection. The management of anorectal infections in neutropenic leukemia patients is not straightforward, as there are no well-conducted studies on this entity. This review seeks to provide a framework into the pathophysiology and clinical presentation of anorectal infections in neutropenic leukemia patients, propose a diagnostic approach and to discuss controversies in the management of this condition.

Does Anti-TNF-α Therapy Affect the Bacteriological Profile of Specimens Collected from Perianal Lesions? A Retrospective Analysis in Patients with Crohn's Disease. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19052892.

Abstract
Anal abscesses and fistulas are potential complications of Crohn’s disease (CD). Chronic immunosuppression, loose stools, and poor wound healing in this population present challenges to the management of perianal diseases. The purpose of the study was to determine the predominant bacterial species found in specimens from perianal lesions causing anal abscess and/or fistula drainage in hospitalized patients, and to compare the number and type of microorganisms isolated from samples taken from patients undergoing biological therapy or traditionally treated. The outcomes of studies of patients treated for anal abscesses or fistulas from 2017 to 2019 were evaluated. Data obtained from medical records included culture and antibiotic sensitivity results of swabs from perianal lesions of isolated microorganisms. A total of 373 swabs were collected from perianal lesions during the analysis period, including 51 (49 positive samples) from patients with CD. The predominant pathogen was Escherichia coli (55%, p < 0.001), the second most common microorganism was Staphylococcus aureus (14.3%, p < 0.001). In vitro susceptibility testing showed E. coli, ESBL (strain with Extended Spectrum Beta-Lactamase) in five cases, S. aureus, MRSA (methicillin-resistant S. aureus -resistant to all beta-lactam antibiotics: penicillins with inhibitors, cephalosporins, monobactams, carbapenems, except for ceftaroline) in one sample. Biologic therapy does not affect the type of microorganisms isolated from perianal abscesses in patients with CD.

Abstract
Fluoroquinolones may be a good alternative for the treatment of bacterial peritonitis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). To test their efficiency against Gram-positive bacteria, we treatedwith intraperitoneal (i.p.) ciprofloxac in 30 episodes of Gram-positive bacterial peritonitis without manifest tunnel infection of the peritoneal catheters. Treatment was sustained for 5 days, then orally for 10 further days. Clinical and bacteriological responses were satisfactory in 25 cases, but resolution of infection was slow in 5 cases of Staphylococcus aureus. The minimal inhibitory and bactericidal concentrations were 0.06250.50 and 0.125-1.0 μg/mL respectively, lower than the plasma and dialysate concentrations of the drug. Side effects were negligible. We conclude that ciprofloxacin provides a good therapeutic alternative to more widely used antibiotics for the empirical treatment of peritonitis in patients undergoing CAPD. However, combinations of antibiotics may be necessary, in Staphylococcus aureus peritonitis.

Abstract
BACKGROUND Anorectal complications are common in patients with haematological malignancies. OBJECTIVES The objectives are to characterize anorectal complications in these patients, identify risk factors and shed light on treatment, morbidity and mortality rates. PATIENTS AND METHODS A retrospective, observational study that included 83 inpatients with haematological malignancies and proctological symptoms from January 2010 to September 2015 was conducted. Clinical outcomes were obtained through a detailed review of medical records. RESULTS The median age was 56 years, and 52 (62.7%) patients were men. Fifty-six (67.5%) patients had nonseptic anorectal complications and 27 (32.5%) patients had septic anorectal complications. RISKS FACTORS Patients with septic anorectal complications were more commonly male, older, and had lower absolute neutrophil counts, but the differences were not statistically significant (P=0.79, 0.67 and 0.89, respectively). In positive blood cultures [23/70 (32.9%)], Enterococcus faecium, Klebsiella pneumonia, and Escherichia coli were the most common isolated agents. TREATMENT In nonseptic anorectal complications, conservative treatments/minor proctological procedures were adopted, and patients with septic anorectal complications were treated with antibiotics±major proctological procedures and/or surgical drainage/debridement. RESULTS OF TREATMENT Forty-eight (85.7%) patients in the nonseptic complications group improved compared with 23 (85.2%) patients in the septic complications group. The overall mortality rate was 2.4% (n=2), with one (1.2%) death related to perianal sepsis. CONCLUSION Enterococcus spp. were more commonly identified in this study and can be increasing in this specific population. In contrast to other reports, we did not identify an association between septic anorectal complications and possible risk factors such as male sex, younger age or a low absolute neutrophil count. Most patients had nonseptic anorectal complications. A major proctological procedure/surgical debridement should always be applied in septic complications, which have better prognoses now than in the past.

Abstract
PURPOSE To use magnetic resonance (MR) imaging to document the appearance of perianal infection in patients with a hematologic malignancy (HM) compared with that in immunocompetent control patients. MATERIALS AND METHODS After an ethical waiver was obtained, 38 patients with an HM were matched by age and sex to 38 control patients with no history of immunocompromise or Crohn disease. Both groups had undergone MR imaging for perianal symptoms and/or systemic sepsis. Two radiologists who were blinded to the diagnosis independently reviewed the MR images and recorded the size and distribution of abscesses and/or fistula tracts, the extent of perianal edema, and the likely diagnosis. Groups were compared by using the Mann-Whitney-Wilcoxon, χ(2), or Fisher exact test. Receiver operating characteristic (ROC) curves were constructed to estimate the ability of MR imaging to help distinguish patients with an HM from control patients. RESULTS Patients with an HM had significantly greater perianal edema than did control patients (mean arc angle of anal canal involved, 220° vs 60°; P < .001). However, they had significantly lower rates of fistula (15 [39.5%] vs 35 [92.1%] of 38; P < .001). Abscesses were similar in frequency (10 [26.3%] vs 17 [44.7%] of 38; P = .15) and were unrelated to the degree of neutropenia (P = .71) or the use of chemotherapy (P = .10). Surgical treatment was rarely required in patients with an HM, either during the acute illness (four [10.5%] of 38) or thereafter (three [7.9%] of 38). MR imaging had an excellent ability to help discriminate patients with HM from immunocompetent patients (areas under the ROC curve, 0.91 and 0.97). CONCLUSION Perianal infection in patients with an HM is more likely to cause diffuse perianal edema and is less likely to cause fistulas than in immunocompetent patients. MR imaging can help distinguish patients with an HM from those without immunocompromise.

Abstract
INTRODUCTION The aim of this study was to examine the type and frequency of perianal conditions in a contemporary series of febrile neutropenic patients and to examine the risk factors, management options and outcome of septic perianal conditions. METHODS Medical records of all adult febrile neutropenic patients (933 patients) who were admitted during the period from January, 2009 to December 2011 were retrospectively review. All patients with perianal complaints or conditions were included. The clinical features, management and outcome of septic conditions were recorded. RESULTS Of all the reviewed charts, 101 (10.8%) had perianal complaints or conditions. Most of them were non septic (74.3%), like piles and fissures, and were treated conservatively. In 26 patients the diagnosis was a septic condition: abscess (12 patients), fistula (4), inflammation (9) and necrotizing fasciitis (1). Septic conditions were more commonly found in males younger than 40 years. Surgery was done in 13 patients to drain a collection and in 2 patients to debride necrotic tissue. Most patients who had no collection had conservative management. There was 1 fatality only (3.8%) in those 26 patients. CONCLUSION Most of the perianal conditions in febrile neutropenic patients are non septic and are managed conservatively. Septic perianal conditions are not associated with a poor prognosis as in the past. Surgical drainage should be reserved to conditions where there is a collection; otherwise patients should be managed conservatively but with close monitoring.

Abstract
Most childhood tumors will first present to a physician; some tumors will present in an atypical manner and may mimic a surgical condition. The diagnosis may be missed if the surgeon is not aware of the possibility of cancer. A very great number of rare presentations of childhood cancer have been described in the literature. It is important that the surgeon who is not experienced in the management of childhood cancer is aware that an apparently benign condition could be a manifestation of an underlying malignancy [71, 83] (Table 22.1).

Abstract
Choices of empirical antibiotic therapy for patients with febrile neutropenia must be made with very little information about the source and site of infection. The clinician is aided by recognition of the subtle signs and symptoms of infection in immunocompromised patients. National guidelines should be applied according to the microbiological patterns and trends in drug resistance at each institution. Case studies are provided to illustrate these challenges in daily practice.

Abstract
Despite improvements in the supportive care of immunosuppressed patients controversy still surrounds the surgical management and outcome of anorectal sepsis in these patients. We reviewed 83 immunocompromised patients with diagnosis of perianal sepsis from 1995 to 1997. Sixty-six patients (80%) were followed for a mean of 15 months. Mean age was 44 years and 76 per cent were males. Twenty-eight per cent were HIV+, 34 per cent had inflammatory bowel disease on steroids, 20 per cent had malignancies, and 18 per cent had diabetes. Twenty-eight per cent had anal fistula, 2 per cent had perianal abscess, and 40 per cent had both. Primary sites of fistula were: transsphincteric (38%), intersphincteric (33%), superficial (20%), and suprasphincteric (3%), and multiple tracks (6%). Horseshoeing was present in 14 per cent of cases. The most commonly practiced surgical procedures were primary fistulotomy (n = 23) and fistulotomy plus drainage (n = 28). Seven patients underwent fistulotomy and ostomy and eight patients were treated with fistulectomy plus drainage. Most wounds (91%) healed within 8 weeks. Incontinence (6%) and recurrence (7%) were the most commonly observed complications. These results are similar to those seen in the general population. Perianal sepsis can be safely managed in immunocompromised patients, with high rates of healing and low complication rates. An aggressive sphincter-preserving approach in the management of these patients may be undertaken.

Abstract
BACKGROUND Infections are a major cause of mortality in neutropenic patients. They require long hospital stays and highly expensive therapeutic measures. In this review we discuss the practical and pharmaco-economic aspects of the management of febrile neutropenia. PREVENTION AND THERAPY Prevention of fever of unknown origin (FUO) demands hygienic and antimicrobiotic measures. First-line antibiotic therapy consists of an aminoglycoside combined with an ureidopenicillin or a 3rd-generation cephalosporin. Double beta-lactam antibiotic combinations are equally effective and less toxic, but more expensive. Monotherapy with carbapenems, ceftazidime, or cefepime appear to offer comparable efficacy. Lung infiltrates require immediate treatment with amphotericin B. If the initial therapeutic regime fails, a carbapenem plus a glycopeptide antibiotic and a parenteral antimycotic drug should be applied after 3 to 4 days. The prophylactic or interventional administration of hematopoietic growth factors is only indicated in special high-risk situations. CONCLUSIONS Using the described therapeutic procedure, the response rate exceeds 90%. Consistent, step-wise escalating administration of antibiotics is essential. More evaluation is needed to determine whether selected patients with febrile neutropenia can be treated on an outpatient basis.

Abstract
The microbiology of perirectal abscesses in 144 patients was studied. Aerobic or facultative bacteria only were isolated in 13 (9%) instances, anaerobic bacteria only were isolated in 27 (19%) instances, and mixed aerobic and anaerobic flora were isolated in 104 (72%) instances. A total of 325 anaerobic and 131 aerobic or facultative isolates were recovered (2.2 anaerobic isolates and 0.9 aerobic isolates per specimen). The predominant anaerobes were as follows: Bacteroides fragilis group (85 isolates), Peptostreptococcus spp. (72 isolates), Prevotella spp. (71 isolates), Fusobacterium spp. (21 isolates), Porphyromonas spp. (20 isolates), and Clostridium spp. (15 isolates). The predominant aerobic and facultative bacteria were as follows: Staphylococcus aureus (34 isolates), Streptococcus spp. (28 isolates), and Escherichia coli (19 isolates). These data illustrate the polymicrobial aerobic and anaerobic microbiology of perirectal abscesses.

Abstract
These complex anorectal conditions are difficult to diagnose because clinical features overlap. In general, an aggressive approach is reserved for hidradenitis suppurativa and necrotizing infections. Patients with Crohn's disease, hematologic disorders, or AIDS are often treated more conservatively, but the correct timing and degree of aggressiveness of surgical intervention may considerably improve the overall outcome. The increasing incidence of AIDS and the frequency with which infected patients present to surgical clinics make it imperative that all surgeons have a working knowledge of the conditions associated with this syndrome. Expertise is required not only to diagnose and treat these conditions but also to protect oneself and others from being inadvertently infected with the HIV. A high index of suspicion and constant vigilance permit the successful resolution of many of these challenging problems.

Abstract
Neutrophils have a critical role in host defense. Reduction in the absolute neutrophil count to below 1,000/μL is associated with increased susceptibility to infection. The pattern of infections depends on the severity and the duration of neutropenia and other associated defects in host defense mechanisms and exposure to antibiotics and other drugs, particularly corticosteroids and immunosuppressive agents. Breaks in the integrity of the skin or the gastrointestinal mucosal surfaces serve as the portals of entry for the majority of infecting organisms. Empiric antibiotic therapy and hospitalization are almost always required for the management of fever (temperature >38.2°C) in a neutropenic patient. A single antibiotic (e.g., ceftazidime or imipenem) or a combination of antibiotics with activity against both gram-positive and gram-negative organisms usually provides effective antimicrobial therapy. In low-risk patients, trials of out-patient therapy are ongoing. When febrile neutropenia does not respond to empiric broad-spectrum antibacterial therapy, fungal infections, particularly Candida and Aspergillus, should be considered, and antifungal therapy should be initiated. Recently, availability of the hematopoietic growth factors, particularly G-CSF and GM-CSF, have changed the approach to prevention and treatment of neutropenia. Randomized controlled studies have established that these growth factors accelerate hematopoietic recovery following chemotherapy and bone marrow transplantation. By shortening the duration of neutropenia, many of the heretofore inevitable problems with fever and infection can be avoided. The only major factor limiting the use of these agents is their cost. Despite the use of these growth factors, some patients will still experience slow hematopoietic recovery. For these patients, use of neutrophil transfusions, possibly from G-CSF-stimulated normal donors, may prove to be a useful adjunctive therapy.

Abstract
Improvement in supportive care including the introduction of new antibiotics, antiviral and antifungal agents and haematopoietic growth factors have all contributed to a decreased chemotherapy-related mortality and morbidity in cancer patients. However, infections/septic shock during neutropenia still constitutes a major threat to these patients. Most patients develop fever during neutropenia and in 20-40% a manifest bacteremia is documented. In patients with prolonged neutropenia, the risk for fungal infections is increased. The spectrum of bacterial, fungal and viral infections in the neutropenic patient is reviewed.

Abstract
In this prospective multicenter trial, treatment strategies for 1573 patients with neutropenia < 1000/microliters and fever > or = 38.5 degrees C after cytotoxic chemotherapy were compared. Patients with unexplained fever were randomized to a three-phase sequential study for different established drug regimens. If an infection could be defined microbiologically or clinically, treatment modifications were determined. In phase I, treatment for all patients consisted of acylaminopenicillin (PEN) plus aminoglycoside (AMG); or third-generation cephalosporin (CEPH) plus AMG; or PEN plus CEPH. In 800 patients with unexplained fever the response rates were: PEN/AMG (n = 258): 74.4%, CEPH/AMG (n = 252): 73.4%; PEN/CEPH (n = 290): 70.0%. Total response rate was 72.5%. In phase II, patients not responding after 3 days received PEN/CEPH/vancomycin (n = 70) or PEN/CEPH/AMG (n = 74). The respective response rates were 52.9% and 55.4%, total 54.2%. If fever did not resolve, the patients received either PEN/CEPH (n = 40) or imipenem/cilastatin (n = 59) both in combination with amphotericin-B/5-flucytosin/rifampin. The response rates were 62.5% and 79.7%, respectively (p = 0.07), total 72.7%. No significant differences between the treatment modalities compared were found. Analyzing all three phases together, 91.3% of patients with unexplained fever were cured. The response rate was also analyzed according to patients with gram-positive bacteremia (n = 183), response rate = 82.5%; gram-negative organisms (n = 145) 78.6%; fungemia (n = 51) 43.1% (p < 0.001); lung infiltrates (n = 269) 61.3% (p < 0.001); clinically documented infections (n = 198) 84.4%; and clinically and microbiologically documented infections (n = 84) 82.1%. If infections were diagnosed after at least 5 febrile days, more lung infiltrates and fungal infections occurred (p < 0.001). Leukocytes rising above 500/mu during the infection predicted better response rates (p < 0.001): in unexplained fever 97.8% vs 86.5% and lower death rates 1.5% vs 8.5%. In documented infections the response rates were then 89.9% vs 62.3% and the death rates 7.0% vs 20.5%. Therapy of neutropenic fever and infections must be adapted according to risk factors and should include early empiric antifungal therapy. The therapeutic and prophylactic use of hematopoietic growth factors to overcome neutropenia should be evaluated.

Abstract
PURPOSE This study was designed to evaluate the spectrum, clinical presentation, management, and outcome of anorectal disease in neutropenic leukemic patients and to compare operative and nonoperative management in neutropenic leukemic patients. METHODS A retrospective review of hospital records was performed. RESULTS One hundred fifty-one of 2,618 (5.8 percent) patients hospitalized with leukemia had concomitant symptomatic anorectal disease. Data from 81 patients were available for analysis. Fifty-two (64 percent) were treated nonoperatively and 29 (36 percent) underwent operative treatment. Fifty-seven (70.4 percent) had absolute neutrophil counts < 1,000/mm3, and 54 (66.7 percent) were severely neutropenic (absolute neutrophil count < 500/mm3). Management and outcomes of 54 severely neutropenic patients were analyzed. In 20 patients who underwent surgery there were 4 deaths (20 percent) and 4 recurrences (20 percent), whereas in 34 patients managed nonoperatively there were 6 deaths (18 percent) and 4 recurrences (12 percent) (P > 0.05). CONCLUSIONS Symptomatic anorectal disease afflicted 5.8 percent of hospitalized leukemic patients. In these patients, anorectal sepsis was a major source of mortality. Our data suggest that anorectal abscesses in neutropenic leukemic patients may be safely drained. Because we did not observe excessive morbidity or mortality (20 percent vs. 18 percent) in the operated neutropenic leukemics as compared with the nonoperated patients, selected neutropenic leukemic patients should not be denied anorectal surgery when otherwise indicated.

Abstract
Rats were used as a model for a living heterotopic cardiac allograft organ transplant. Rats treated in this model with recombinant rat interferon-gamma (IFN-gamma) showed accelerated rejection in a dose-dependent fashion. However, rats treated with maintenance doses of cyclosporine and IFN-gamma expressed increased rejection at 20 days that had resolved completely by 45 days post-transplantation. Polymorphonuclear leukocytes (neutrophils) were isolated from the blood of rats, and their function was determined by treating the cells with f-Met-Leu-Phe (fMLP) and measuring superoxide produced. Results indicate that the neutrophils from rats treated with maintenance doses of cyclosporine and IFN-gamma still had increased IFN-gamma-modulated fMLP-induced respiratory burst and that maintenance cyclosporine therapy can inhibit the IFN-gamma-mediated accelerated rejection without compromising the antimicrobial effects of IFN-gamma treatment.

Abstract
In most centers treating cancer patients, significant progress has been made in permitting patients to survive even prolonged courses of neutropenia. This has resulted from a better understanding of the epidemiology of infection and the points during the clinical course when they pose a risk for the patient with prolonged neutropenia. Considerable benefit has been derived from the availability of more potent broad-spectrum antimicrobial agents and from organized strategies for when they should be initiated, how and when they should be modified, and for how long they should be continued. The possibility that the duration of neutropenia might be attenuated in patients receiving chemotherapy now seems real with the ever-expanding repertoire of cytokines and other biologic agents that augment the hematopoietic and immune systems. Coupled with the use of peripheral stem cell reconstitution or the insertion of genes into hematopoietic stem cells that might render them resistant to the cytocidal effects of certain chemotherapeutic agents, it now seems possible to envision regimens that might alter the consequences of neutropenia as we have come to know them. It is likely, therefore, as additional experience is garnered and as chemotherapy regimens are devised, that the optimal approach to the management of the patient with prolonged neutropenia will include the rational use of antibiotics together with cytokines and other biologicals. Hopefully, such regimens will permit the delivery of chemotherapy in a manner that might enhance its tumoricidal activity and improve the outcome of patients with cancer.

Abstract
A retrospective study of all patients presenting with acute leukemia to a single institution during the period 1968-1988 was undertaken to determine the type and incidence of surgical complications. One hundred twenty-eight of 296 patients were identified as requiring a surgical consultation for complications occurring during the course of the disease and many surgical disciplines were involved. Operative intervention was often required for these complications. Pediatric surgical specialists need to be aware of the range of surgical complications that can occur in children with acute leukemia and they must work in close co-operation with pediatric medical oncologists to ensure optimal treatment for all patients.

Abstract
The role of operation for anorectal infections associated with perineal gangrene and cellulitis in children with myelo-suppression from cancer chemotherapy is unclear. We evaluated anorectal/perineal infections caused by Pseudomonas aeruginosa in 16 children with malignant diseases seen over 27 years. In 12 of 16 patients, leukemia was the underlying malignancy (ALL 10, AML 2), and in 13 of 16, severe neutropenia (absolute neutrophil count less than 500/mm3) was present at diagnosis. Cultures of the lesions showed multiple organisms in 14 of 16 patients with Escherichia coli, Klebsiella species, and Enterococcus being the most frequent coexisting organisms. All positive blood cultures grew P aeruginosa exclusively. Of three patients with necrotizing infections, two had complete resolution with medical treatment alone; the other patient who developed this problem while on terminal care died. In none of the 16 patients was a major operation (debridement or diversion) performed. Five patients died, three of whom were considered terminally ill when the anorectal infections occurred. Four of the five deaths occurred before 1974. Since then, only 1 of 7 patients died. Excluding the three terminally ill patients, the success rate of medical therapy alone is 85% (11/13). The antibiotic regimen should include an aminoglycoside in synergistic combination with anti-Pseudomonas penicillin. These results suggest that operative management may have no role in the management of anorectal infections caused by P aeruginosa in children with cancer.
