INTRODUCTION
Fournier's gangrene is a rare but life-threatening form of necrotizing soft tissue infection involving the perineal, genital, or perianal region, commonly caused by a mix of aerobic and anaerobic organisms. Initially discovered in dental abscesses, Streptococcus anginosus have been increasingly reported in pyogenic and systemic infections with abscess formation. We present a rare case of perineal abscess that developed into Fournier's gangrene in which the causative pathogen isolated was S. anginosus.
PRESENTATION OF CASE
A 58-year-old male with uncontrolled type 2 diabetes, hypertension and hidradenitis suppurativa of the groin, presented with worsening testicular pain. He was found to have a necrotizing soft tissue infection of the perineum, consistent with Fournier's gangrene. He was successfully treated with multiple surgical debridement and broad-spectrum intravenous antibiotics. He was transitioned to oral antibiotics before transferring to a tertiary care facility for reconstruction.
DISCUSSION
The setting of uncontrolled diabetes and hidradenitis suppurativa may be the likely etiology for this peculiar case of Fournier's gangrene secondary to S. anginosus. Compromised tissue integrity and impaired local immune defenses from these etiologies predisposes to the development of Fournier's gangrene. Historically, these abscesses typically resolve after intravenous antibiotics and incision and drainage. However, the abscess in this case did not resolve but rather progressed to Fournier's gangrene. Perineal abscesses that grow S. anginosus should raise a high index of suspicion for worse outcomes.
CONCLUSION
In conclusion, we recommend a multidisciplinary approach and rapid diagnosis for the management of S. anginosus in the setting of a perineal abscess, with early aggressive surgical debridement and broad-spectrum antibiotics.

Actinotignum schaalii (formerly known as Actinobaculum schaalii) is an anaerobic or facultative anaerobic gram-positive bacillus that can be found commensally in the urogenital region. It can be overlooked because it grows slowly and is difficult to identify with classical microbiology laboratory techniques. Colonies become visible after 48-72 hours of incubation on blood agar in anaerobic or CO₂-rich media. While it typically causes urinary tract infection in older individuals, cases of bacteremia, vertebral osteomyelitis, endocarditis and cellulitis have been reported. Fournier's gangrene caused by A.schaalii has been reported very rarely so far. Fournier's gangrene has been defined as necrotizing fasciitis of the external genitalia, perineal and perianal region. Diabetes, immunosuppression, peripheral vascular disease, urethral anomalies, chronic alcoholism and smoking are important predisposing factors. In addition, approximately 25% of the cases have no known or identifiable etiology. The bacteria causing the infection may originate from skin, urogenital or intestinal microbiota. In this case report, a new case of Fournier's gangrene caused by A.schaalii was presented. A 65-year-old male patient admitted to the emergency department with the complaints of pain, swelling, redness in the left testis and also nausea, vomiting and chills that started three days ago. Physical examination revealed increased diameter of the scrotum, intense hyperemia of the skin and foci of necrosis. It was learned that the patient had no known chronic disease other than benign prostatic hyperplasia. The patient reported smoking of 25 packs of cigarettes per year. Routine laboratory tests revealed leukocyte= 32.41 x 109/L, neutrophil= 89.9%, procalcitonin= 1.62 ug/L, CRP= 265.07 mg/L and the patient was operated with the diagnosis of Fournier's gangrene. Gram staining of the abscess specimen obtained during the operation showed gram-positive bacilli both inside and outside the leukocytes. After 24 hours, grampositive bacilli were detected in the Gram staining of thin, transparent/gray colonies grown on 5% sheep blood and chocolate agar. The isolate was identified as A.schaalii by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) VITEK® MS (bioMérieux, France) microbial identification system. VITEK®2 ID ANC (bioMérieux, France) bacterial identification card was also used for comparison but the bacteria could be identified. As a result of the sequence analysis performed for confirmation, it was shown to be 100% homologous with Actinobaculum schaalii (GenBank accession no: FJ711193.1). For susceptibility tests, 5% sheep blood Schaedler agar was used and incubated in anaerobic environment. According to the minimal inhibitory concentration (MIC) results evaluated after 48 hours, penicillin was found to be 0.032 mg/L, clindamycin 0.125 mg/L, ciprofloxacin 0.19 mg/L, ceftazidime 4 mg/L, and amoxicillin 0.19 mg/L. The primary cause that initiated the infection in the case could not be identified, but it was thought that the presence of prostatic hyperplasia and smoking history may have contributed to the occurence or the progress of the disease. It is noteworthy that the ciprofloxacin MIC result was quite low compared to other studies. In addition, this study revealed the value of MALDI-TOF MS based methods in identification. In conclusion, it is thought that a significant proportion of A.schaalii infections may be overlooked due to the difficulty in growth and identification. Increasing the diagnostic power of clinical microbiology laboratories for poorly identified bacteria and renewing the databases of commercial identification systems are important for the early and accurate diagnosis and treatment of serious infections that may occur with such agents.

OBJECTIVE
The epidemiological profile of anal fistula and anorectal abscess has not been well studied. Based on the results of a retrospective cross-sectional survey, we aimed to investigate the potential influential factors associated with anal fistula and anorectal abscess.
METHODS
We conducted a retrospective analysis of outpatients who visited the proctology department at China-Japan Friendship Hospital between January 2017 and May 2022. A comprehensive questionnaire was designed to collect potential influential factors, and according to formal anorectal examination and the corresponding diagnostic criteria, all the participants were divided into patients with anal fistula or perianal abscess and healthy control group. Multiple logistic regression was used to identify factors in significant association with anal fistula and perianal abscess. Additionally, we combined restricted cubic spline regression to examine the dose-response relationship between factors and the risk of developing anal fistula or anorectal abscess.
RESULTS
The present study included 1,223 participants, including 1,018 males and 206 females, with 275 anal fistulas, 184 anorectal abscesses, and 765 healthy controls. We found no statistically significant differences between patients and controls in basic information and preoperative assessment of life factors, except for body mass index. It was indicated that people with overweight or obesity were more prone to anal fistula (OR = 1.35, 95% CI: 1.00-1.82, = 0.047; OR = 3.44, 95% CI: 2.26-5.26, < 0.001) or anorectal abscess (OR = 1.41, 95% CI: 1.00-1.99, = 0.05; OR : 2.24, 95% CI: 1.37-3.67, = 0.001) than normal-weight individuals. The dose-response research indicated the J-shaped trend between the ascending BMI levels and the higher risk of suffering from anal fistula and anorectal abscess.
CONCLUSIONS
Our findings indicate that overweight and obesity are risk factors for anal fistula and anorectal abscess, which plays a role in the prevention of anorectal diseases. This provides some theoretical basis for clinicians to provide health education to their patients.

BACKGROUND
Managing complex perianal fistulizing Crohn's disease (CD) remains challenging, despite current medical and surgical treatment approaches. Darvadstrocel, a therapy utilizing adipose-derived stem cells, shows promise in promoting tissue regeneration and healing, offering a novel and effective treatment for fistula management.
METHOD
A systematic literature search was conducted on PubMed and Scopus to identify studies involving patients with complex perianal fistulizing CD treated with darvadstrocel.
RESULTS
In total, 2 randomized controlled trials (RCT), 5 observational studies with retrospective data collection and 2 observational studies with prospective design were included in the final review. Data from the European ADMIRE-CD RCT demonstrated that darvadstrocel is superior to placebo in terms of clinical and imaging improvement over both the short and long term. These findings align with the prospective studies analyzed in this systematic review. The rate of treatment-emergent adverse events in the ADMIRE-CD trial's RCTs was similar in both the darvadstrocel and control groups, with perianal abscess being the most common adverse event up to 52 weeks after drug administration. Retrospective studies indicated no side-effects beyond 52 weeks.
CONCLUSIONS
Darvadstrocel appears to be a new, potentially effective and safe treatment option for the management of complex perianal fistulas. However, more randomized clinical trials are needed to evaluate the efficacy and safety profile of the drug.

Hidradenitis suppurativa (HS) is a chronic, debilitating inflammatory disorder of the hair follicles that localizes to the intertriginous and anogenital regions of the body. Lesions are characterized by inflammatory nodules, subcutaneous abscesses, fibrosis, and sinus tracts. Crohn's disease (CD) is an idiopathic chronic inflammatory bowel disease that affects any part of the gastrointestinal tract. Multiple treatment options exist for CD, including monoclonal anti-tumor necrosis factor alpha (TNF-α) antibodies like adalimumab (Humira). Adalimumab is an anti-TNF agent that has been approved by the United States Food and Drug Administration (FDA) for the treatment of HS. A 35-year-old African American male with a history of fistulizing CD presented to the hospital for evaluation of severe pain and purulent drainage from open sores in his bilateral axillary regions, groin, buttocks, and face for four days. He was on adalimumab for two years, during which time he noted the development of Hurley stage III HS. The physical exam was remarkable for a cachectic, painful-appearing male, with multiple abscesses on his lower jaw extending to his upper neck draining thick serosanguinous fluid, with similar findings in his bilateral axillary regions, bilateral groin, and perianal regions. He was treated with intravenous antibiotics consisting of a fourth-generation cephalosporin and vancomycin. While the etiology of HS in this patient is inconclusive, the timing of its development closely aligns with the initiation of Humira and is not a manifestation of CD. Paradoxical adverse effects describe a phenomenon in which a medication can induce a condition that it classically can be used to treat. In this patient's case, it was HS.

Rectal perforation secondary to an ingested foreign body is a rare occurrence that can be challenging to diagnose. It may initially present as a perianal abscess. Herein, we report a rare incident involving a patient who presented with a perianal abscess. The initial assessment and an abdominal CT scan revealed a large horseshoe perianal abscess with a small linear hyperdensity noted near the anal verge. The patient was taken to the operating room, where he was found to have perforated the rectum due to an ingested chicken bone. The procedure involved the incision and drainage of the abscess, along with the removal of the foreign body.

Background Diagnosis and management of perianal abscesses (PAA) are based on history and clinical examination. Imaging is not indicated except in complicated cases, as determined by the surgical team. The monetary, ionizing radiation, and resource utilization costs of a computed tomography (CT) scan in the emergency room must be considered when used for diagnostic purposes of PAAs. Methods A retrospective analysis of 129 patients diagnosed with a diagnosis of PAA between 2015-2020 was performed. The primary endpoints included length of stay, CT performed, time from patient presentation to CT, and CT scan completion prior to surgical consultation. Data is reported as n (%) or median (IQR). Results Of the 129 patients diagnosed with PAA, 81 underwent CT, and 48 did not. General surgery was consulted in 88% of cases. There were no statistically significant differences in age (p=0.562), sex (p=0.531), or ethnicity (p=0.356). The median hospitalization time was two days when CT was performed (p=0.001). The median time elapsed from presentation to the emergency department and CT scan performed was 16 hours (p=0.001). CT scans were ordered before the surgical consultation in 65% of cases (p=0.001) and 17% after a surgical consultation was placed (p=0.009). Conclusion Performing CT scans prior to surgical evaluation for the diagnosis of PAA is not a responsible practice. The cost, resources, and radiation exposure must be considered. This study demonstrated that more CT scans are ordered prior to surgical consultation for PAA, resulting in a prolonged wait time in the emergency department.

A 34-year-old male presented with spontaneous rectal pain. He was diagnosed with a posterior rectal wall abscess 7 cm proximal to the anal verge that was confirmed on an MRI (magnetic resonance imaging) pelvis. This abscess was drained through a transrectal route. Rectal wall abscess is an exceedingly rare pathology compared to perianal abscess; therefore, this case highlights the key aspects of its management.

Perianal fistula and its recurrence is a challenging entity for surgeons. It is a well-establi1shed fact that magnetic resonance imaging (MRI) findings influence surgical procedures and reduce the rate of recurrence. In this study, we assessed the contrast-enhanced (CE) three dimensional T1 sequences [sampling perfection with application optimized contrast using different flip angle evolution (SPACE) and volumetric interpolated breath-hold examination (VIBE)] in a 3T MRI system to evaluate perianal fistulas and compared them with two-dimensional (2D) sequences. Forty-four patients (mean age, 38.8 ± 15.3 [standard deviation]; 32 males, 12 females) with perianal fistula were included in this prospective study. The patients underwent conventional noncontrast, 2D sequences, diffusion-weighted imaging, followed by postcontrast, 2D T1 images in both axial and coronal planes, and 3D sequences at 3T. Acquisition times were recorded for each sequence. Each postcontrast sequence was evaluated in terms of image quality, presence of artifacts, fistula type, presence of an abscess, visibility, and number of internal orifices. The surgical findings were considered the gold standard. The imaging findings were compared with the surgical findings. In all three sequences, the fistula type and abscess were identified correctly in all patients. The sensitivity value for identification of ramifications utilizing CE 3D T1 VIBE sequence, CE 3D T1 SPACE, and CE 2D T1 images was 100, 86, and 36%, respectively. The number of internal orifices was identified by the CE 3D T1 VIBE and CE 3D T1 SPACE sequences in 100 and 92% of patients, respectively. CE 2D T1 images correctly identified internal orifices in 80% of patients. The overall scan time for each 3D sequence was shorter than for the combined postcontrast 2D sequences. CE 3D T1 SPACE and CE 3D T1 VIBE sequences outperformed conventional CE 2D sequences in the evaluation of perianal fistulas in terms of visibility and the number of internal orifices with a shorter scanning time. Among the 3D sequences, CE 3D T1 VIBE is slightly superior to CE 3D T1 SPACE sequence.
