BACKGROUND
Rectal mucosal melanoma is a rare and highly aggressive disease. Common symptoms include anal pain, an anal mass, or bleeding. As such, the disease is usually detected on rectal examination of patients with other suspected anorectal diseases. However, due to its rarity and nonspecific symptoms, melanoma of the rectal mucosa is easily misdiagnosed.
CASE SUMMARY
This report describes the case of a 58-year-old female patient who presented with a history of blood in her stool for the prior one or two months, without any identifiable cause. During colonoscopy, a bulge of approximately 2.2 cm × 2.0 cm was identified. Subsequently, the patient underwent endoscopic ultrasound (EUS) to characterize the depth of invasion of the lesions. EUS suggested a hypoechoic mucosal mass with involvement of the submucosal layer and heterogeneity of the internal echoes. Following surgical intervention, the excised tissue samples were examined and confirmed to be rectal malignant melanoma. The patient recovered well with no evidence of recurrence during follow-up.
CONCLUSION
This case shows that colonoscopy with EUS and pathological examination can accurately diagnose rare cases of rectal mucosal melanoma.

Women living with human immunodeficiency virus are at an increased risk of developing cancers related to human papillomavirus (HPV). Thus, it is important to combine clinical assessments, serological screening, and HPV data for planning prevention policies. This study aimed to identify HPV and its specific types in the cervical, anal, and oral mucosa of HIV-seropositive women, associating it with viral load and lymphocyte count. Sociodemographic characteristics, health data (CD4+ and CD8+ T cell counts and viral load), and biological samples (cervical, anal, and oral) were collected from 86 HIV-positive women undergoing antiretroviral therapy. Data were classified according to the presence or absence of HPV-DNA, HPV-DNA presence at one or more anatomic sites, and level of oncogenic risk, considering low- and high-risk oncogenic HPV-DNA groups. The presence of HPV in the cervicovaginal site was 65.9%, 63.8% in anal canal, and 4.2% in oral mucosa. A viral load ≥75 HIV copies/mL was associated with the presence of HPV-DNA. There was an association between viral load and the low-risk HPV or high-risk HPV groups. We found a high prevalence of HPV infection in HIV-seropositive women, particularly in the cervical and anal mucosa, with viral load ≥75 HIV copies/mL being associated with HPV-DNA presence.

The objective of this study was to determine the efficacy of the direct-fed microbial 10-G upon cattle growth performance, liver and lung health, carcass quality, and yield outcomes, as well as prevalence and enumeration of in feces and lymph nodes. Fed beef heifers ( = 1,400; initial shrunk body weight [] 343.3 ± 36.2 kg) were blocked by the day of arrival and randomly allocated to one of two treatments (0 [negative control, CON] or 2 g of a direct-fed microbial [10-G] that provided 1 billion CFUs per animal per day of , , , , and ) with 10 pens per treatment. Recto-anal mucosal fecal samples (; = 477) and subiliac lymph nodes (; = 479) were collected longitudinally at harvest from 23 to 25 heifers per pen. Data were analyzed using mixed models; pen served as the experimental unit; block and harvest date were random effects. No differences were detected in dry matter intake ( = 0.78), final BW ( = 0.64), average daily gain ( = 0.51), gain to feed ( = 0.71), hot carcass weight ( = 0.54), dressed carcass yield ( = 0.52), 12th rib fat depth ( = 0.13), longissimus muscle area ( = 0.62), calculated empty body fat ( = 0.26), or marbling score ( = 0.82). Distributions of liver scores ( ≥ 0.34), quality grades ( ≥ 0.23), and yield grades ( ≥ 0.11) were also not different between treatments. A tendency was detected for more normal lungs ( = 0.08; 10-G = 65.96%, CON = 61.12%) and fewer inflated lungs at harvest for cattle fed 10-G ( = 0.10; 10-G = 0.29%, CON = 1.16%); other lung outcomes did not differ ( ≥ 0.54). prevalence did not differ for RAM samples ( = 0.41; 10-G = 97.74%, CON = 96.82%) or SLN ( = 0.22; 10-G = 17.92%, CON = 13.66%). concentration of RAM samples ( = 0.25; 10-G = 3.87 log CFU/g, CON = 3.32 log CFU/g) or SLN ( = 0.37; 10-G = 1.46 log CFU/g, CON = 1.14 log CFU/g) also did not differ between treatments at harvest. These results do not demonstrate any difference in live animal performance, carcass characteristics, or carriage for heifers fed 10-G.

Chronic intestinal schistosomiasis (CIS) refers to the long-term effects of infection with Schistosoma parasites in the intestines. This condition typically develops after repeated or prolonged exposure to contaminated freshwater containing Schistosoma eggs. The current study reports a case of an adult male, who complained of abnormal abdominal and anal pain for a month and had a medical history of complex perianal fistulae. The endoscopic investigation revealed different degrees of hyperemia, concentrated in the sigmoid colon and rectum. Lesions were localized in the rectum and sigmoid colon. Yellow granular hyperplasia, whether concentrated or dispersed, single or multiple polyps, along with observations of mucosal congestion, edema, faint vascular striations, erosions, superficial ulcers, and scattered petechial hemorrhages were noted. Also, the segmented areas of the colon had different degrees of inflammation. The microscopic histopathological analysis showed a culprit of surgical scar tissue. The granulomas harbored Schistosome parasites at the submucosal depth. Also, an erosion in the colonic mucosal tissues accompanied by lymphoplasmacytic and micro-abscess infiltrates was seen. A Schistosoma bilharzial ova was observed in the granuloma at the submucosal level. Endoscopic and histopathological investigations are useful tools to differentiate between CIS and Crohn's disease. These tools can distinguish CIS from Crohn's disease. Early detection and treatment are essential to prevent the progression of the disease and minimize long-term complications.

A 70-year-old male was admitted with severe haematochezia and lipothymia. His medical history was relevant for coronary artery disease and radiation proctopathy. During hospitalization, was hemodynamically stable with persistent haematochezia. Laboratory examination revealed continuous haemoglobin fall, despite erythrocyte reposition, with administration of 11 units since admission. Colonoscopy showed an 8mm fibrinous lesion with an adherent clot, at 40cm from the anal verge. During exploration, a heavy spurting haemorrhage developed, with haemostasis being achieved with 4 clips, followed by site tattoo. Considering the risk of severe bleeding relapse in a high-risk patient, the patient underwent emergent Hartmann type colectomy. Histopathology report revealed a vascular lesion with arterial and venous vessels, protruding through the submucosa, muscular and subserosa, with a focal mucosal erosion, without neoplastic disease, compatible with an arteriovenous malformation (AVM).

BACKGROUND
The rectal and vaginal walls are typically sutured if severe perineal lacerations with rectal mucosal damage occur during vaginal delivery. In case of anal incontinence after the repair, re-suturing of the anal sphincter muscle is standard procedure. However, this procedure may not result in sufficient improvement of function.
CASE PRESENTATION
A 41-year-old woman underwent suture repair of the vaginal and rectal walls for fourth-degree perineal laceration at delivery. She was referred to our department after complaining of flatus and fecal incontinence. Her Wexner score was 15 points. Examination revealed decreased anal tonus and weak contractions on the ventral side. We diagnosed anal incontinence due to sphincter dysfunction after repair of a perineal laceration at delivery. We subsequently performed sphincter re-suturing with perineoplasty to restructure the perineal body by suturing the fascia located lateral to the perineal body and running in a ventral-dorsal direction, which filled the space between the anus and vagina and increased anal tonus. One month after surgery, the symptoms of anal incontinence disappeared (the Wexner score lowered to 0 points), and the anorectal manometry values increased compared to the preoperative values. According to recent reports on the anatomy of the female perineal region, bulbospongiosus muscle in women does not move toward the midline to attach to the perineal body, as has been previously believed. Instead, it attaches to the ipsilateral surface of the external anal sphincter. We consider the fascia lateral to the perineal body to be the fascia of the bulbospongiosus muscle.
CONCLUSIONS
In a case of postpartum anal incontinence due to sphincter dysfunction after repair of severe perineal laceration, perineoplasty with re-suturing an anal sphincter muscle resulted in improvement in anal sphincter function. Compared to conventional simple suture repair of the rectal wall only, this surgical technique may improve sphincter function to a greater degree.

INTRODUCTION AND IMPORTANCE
Buschke-Löwenstein tumor (BLT) is a rare perianal lesion caused by low-risk mucosal HPV 6 or 11 but less frequently associated with high-risk HPV types. It is a large, exophytic, verrucous lesion of the anogenital region. BLT presents as a benign tumor but exhibits malignant clinical behavior and has a high rate of local recurrence and malignant transformation. The optimal treatment approach for BLT is still debated due to the lack of consensus. Various therapeutic modalities have been proposed, including topical agents, surgical excision, immunotherapy, chemo-radiotherapy, and electrocoagulation.
CASE PRESENTATION
This case report presents a heterosexual, immunocompetent patient with anal pain, pruritus, and spontaneous bleeding. The physical examination revealed an exophytic, pedunculated verrucous lesion, which appeared to be a typical fibroepithelial lesion.
CLINICAL DISCUSSION
The patient underwent wide excision, followed by a re-excision due to a surgical margin issue. The tumor exhibited malignant transformation into a well-differentiated SCC. However, due to the tumor's stage, size, location, histological type, and the extended time interval between the two surgeries, postoperative radiotherapy was not performed. Follow-up examinations over 12 months revealed no evidence of recurrence in either the patient's clinical evaluation or pelvic MRI.
CONCLUSIONS
Although comprehensive research is lacking, wide local excision is considered the preferred first-line treatment for early-stage cases without evidence of local invasion. Furthermore, HPV immunization can prevent the development of Buschke-Löwenstein tumor, and early administration of the HPV vaccine is recommended to avoid acquiring HPV infection.

OBJECTIVES
Lateral internal sphincterotomy is a conventional surgical intervention for chronic anal fissures, yet the potential for postoperative anal incontinence underscores the need for an alternative approach. This study aimed to evaluate the outcomes of patients with chronic fissures who underwent a combination of fissurectomy, vertical non-full thickness midline sphincterotomy (VNMS), and mucosal advancement flap (MAF), as a means of mitigating the risk of incontinence.
METHODS
This retrospective analysis included forty-six consecutive patients with chronic anal fissures, unresponsive to topical diltiazem, who underwent fissurectomy combined with VNMS and MAF between April 2018 and May 2023. Primary outcome measures encompassed fissure healing rates. Continence was assessed using the Fecal Incontinence Severity Index (FISI), and manometric assessments were conducted before the procedure and three months postoperatively.
RESULTS
With a median follow-up of 27 months, there were no postoperative complications, and the overall fissure healing rate reached 96% (44/46). At three months post-procedure, FISI scores were reduced to 0, with no instances of fecal soiling. Anal resting pressure exhibited a significant reduction at 3 months [pre-op: 133 (95% CI, 128-150) vs. 3 mo: 109 (95% CI, 100-117) cmHO; = 0.01]. Similarly, maximum anal squeeze pressure showed a significant decrease three months post-surgery [pre-op: 317 cmHO (95% CI, 294-380) vs. 3 mo: 291 cmHO (95% CI, 276-359), = 0.03].
CONCLUSIONS
The combination of fissurectomy, VNMS, and MAF proved to be an effective approach for chronic anal fissures, yielding favorable medium-term outcomes without postoperative anal incontinence.

We report a long-term remission in candidiasis in a 57-year-old Finnish female with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) suffering from recurrent oral, esophageal, gastric, vaginal, and anal candidiasis since childhood. Candidiasis treatment with antifungal medicines fluconazole, itraconazole, posaconazole, voriconazole, caspofungin, nystatin, or amphotericin-B during 2008-2021 had variable effects and intermittent development of antifungal resistance and hospital periods. The patient started using fermented lingonberry juice (FLJ) as a mouth rinse daily in April 2021. No symptoms or mucosal signs of candidiasis in any part of the digestive system or vaginal area have been noticed during this exceptionally long-term 2 ½ year remission in candidiasis without antifungal medications.
