Anogenital psoriasis - clinical picture and therapy

Psoriasis presenting with anogenital lesions is an important medical and social problem that is not sufficiently covered in the literature. The genitals and perianal area are involved in severe plaque and inverse psoriasis. Occasionally, the disease can be localized only in the anogenital zone. Diagnosis of psoriasis with localization on the genitals and/or perianal area is difficult, which is associated with the anatomical and physiological characteristics of the affected area. The manifestations of psoriasis become exudative, infiltration of papules and plaques is expressed little, the borders of rashes lose clarity, peeling on the skin is expressed weakly, in the depth of the folds due to maceration and friction is absent. Subjectively significant localization of the process, its prolonged course, pruritus lead to significant violations of the quality of life of patients and serve as prerequisites for the formation of anxiety-depressive disorders and sexual dysfunction Diagnosis and treatment of anogenital psoriasis presents significant challenges. Clinical guidelines tend to emphasize external therapy with topical corticosteroids and calcineurin inhibitors; in recent years, the efficacy of genetically engineered biological agents, including interleukin-17 inhibitors and phosphodiesterase-4 inhibitors, has been considered. The presented review systematizes information about anogenital psoriasis, peculiarities of its epidemiology, clinical picture, diagnosis and approaches to therapy.

Vulvar lichen sclerosus in girls and adult females: A single-center retrospective study of 744 patients in China.

Vulvar lichen sclerosus (VLS) is a chronic, inflammatory disease which is accompanied by itching and pain, affecting the patient's daily life and sexual activity. However, the disease characteristics of children and adults are not completely the same. Currently, there are few studies in China that compare the characteristics of VLS between girls and adult female patients. The aim of this study was to compare the epidemiology, clinical features, and combined autoimmune diseases of VLS patients between girls and adult females, and to help clinicians better understand VLS in different age groups. We enrolled 744 female patients for analysis, divided by age into a child group (<18 years) and an adult group (≥18 years). Among girl patients, 94.6% had preadolescent onset, while among adult female patients, only 4.6% had preadolescent onset, which was a statistically significant difference. The highest percentage of adult female patients had onset during their child-bearing period (75.4%), while 20% had postmenopausal onset, with a significant difference when the three onset states were compared. White patches were equally common in both girl and adult female patients' external genital area, while mossy lesions and labia minora atrophy were more common in adult female patients. Involvement of the clitoris, labia minora, and vaginal opening area were more common in adult patients. The perianal area was more commonly involved in girl patients. We found eight cases (1.2%) of secondary squamous cell carcinoma in adult female patients. We also found that 13 patients had concurrent lichen sclerosus lesions on the vulva and extragenital region, including two girls and 11 adult females. Extragenital lichen sclerosus (EGLS) occurred mostly in the torso. Clinicians should be aware of these differences so that early diagnosis and treatment of the disease can be achieved, to avoid irreversible anatomical alterations and the risk of cancer.

Impact of Pseudomonas aeruginosa carriage on ICU-acquired pneumonia: a European multicentre prospective cohort study

ObjectivesPseudomonas aeruginosa (PA) is a common causative pathogen of pneumonia acquired in the ICU. The aim of this study was to determine the incidence of PA ICU pneumonia (PAIP) and to quantify its independent association with PA colonisation at different body sites. MethodsAdult patients on mechanical ventilation at ICU admission were prospectively enrolled across 30 European ICUs. PA colonisation in the perianal area and in the lower respiratory tract were assessed within 72 hours after ICU admission and twice weekly until ICU discharge. PAIP development was evaluated daily. Competing risk models with colonisation as a time-varying exposure and ICU death and discharge as competing events were fitted and adjusted for confounders to investigate the association between PA carriage and PAIP. Results1971 subjects were enrolled. The colonisation prevalence with P. aeruginosa in the first 72 hours of ICU admission was 10.4% (179 perianal, 51 respiratory), while the acquisition incidence during the ICU stay was 7.0% (158 perianal, 47 respiratory). Of the 43 (1.8%) patients who developed PAIP, 11 (25.6%) were PA colonised on admission and 9 (20.9%) acquired colonisation prior to PAIP onset. Both perianal (adjusted sub distribution hazard ratio [aSHR] 4.4, 95%CI 1.7-11.6) and respiratory colonisation (aSHR 4.6, 95%CI 1.9-11.1) were independently associated with PAIP development. ConclusionsPAIP incidence was higher in PA colonised vs non-colonised patients. Both colonisation of the rectum and of the respiratory tract were associated with development of PAIP. The increased risk of P. aeruginosa colonisation for subsequent infection provides an opportunity for targeted preventive interventions.

Fournier’s Gangrene Arising from Chronic Ischial Pressure Sore in a Paraplegic Patient: A Case Report

Fournier’s gangrene (FG) is a rare but life-threatening bacterial infection affecting the genital and perianal areas, often associated with high morbidity and mortality rates. Although pressure sores, injuries caused by prolonged pressure on the skin, are considered a risk factor for FG, they are rarely the direct cause of the condition. This case report presents a 65-year-old male with paraplegia and a chronic ischial pressure sore who presented with FG. The patient was treated with prompt surgical debridement and antibiotic therapy, followed by wound reconstruction using a local advancement flap. This enabled a successful outcome, with no further wound issues observed for 6 months. Early diagnosis, imaging modalities, prompt surgical intervention, and appropriate antibiotic therapy are essential for the successful management of FG. This case emphasizes the importance of recognizing the possibility of FG arising from pressure sores and highlights the critical role of early surgical intervention.

Factors Associated with Severe Hidradenitis Suppurativa, Using Hurley Staging and Metascore

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease for which certain risk factors are well known: obesity and smoking (in particular). However, the factors associated with more severe conditions, and therefore potential aggravators of the disease, remain a matter of debate. Our study aims to determine the clinical factors associated with severe HS using several severity scores. Methods: The data were obtained via the ERHS questionnaire from patients exclusively recruited at Erasme Hospital in Brussels. The severity of HS was firstly estimated by the Hurley score, and secondly by a metascore, a system combining the iHS4, HS-PGA, SAHS, and DLQI. Univariable and multivariable analyses were performed. Results: Six hundred and forty-seven patients were included in the Hurley analysis, and 456 patients in the metascore analysis. In multivariable analysis, men have a more severe metascore than women (odds ratio [OR] = 1.89, p = 0.022), smoking was associated with a more severe disease according to metascore, especially in mild cases (OR = 0.76, p = 0.043), and an elevated body mass index was associated with having Hurley stage III disease compared to Hurley I or II disease (OR = 1.09, p = 0.001). A significant association is also shown between blood pressure and Hurley stage (OR = 0.97, p = 0.025). Self-reports of nonsteroidal anti-inflammatory drugs aggravating the disease is also a factor associated with greater severity according to the metascore (OR = 0.12, p = 0.008). Finally, several locations of HS lesions were associated with greater severity, in particular the armpits according to the metascore (OR = 0.29, p < 0.001), and the perianal area according to the Hurley score (OR = 0.15, p < 0.001). Conclusion: HS seems to be more severe in men; smoking seems to aggravate mild cases of HS, while increased body mass index plays a major role in the transition from Hurley II to Hurley III.

7044 It Is Back, Three Decades Later! When To Stop Glucagonoma surveillance?

Abstract Disclosure: A.T. Wahba: None. J.S. Dillon: Advisory Board Member; Self; Crinetics Pharmaceuticals, CA. A 76-year-old woman presented to the Neuroendocrine Tumor (NET) Clinic for evaluation of sore mouth, perianal area and itchy ankles. She had a medical history notable for glucagonoma, status post distal pancreatectomy and splenectomy in 1988, 32 years prior to her current presentation. She recalled that she had CT imaging post operatively for a few years, but no more recent imaging. She was diagnosed with diabetes mellitus in approximately 2002, with highly variable glucose control. She developed a left leg DVT with pulmonary emboli one year prior to presentation. Shortly after her thromboembolic events, she noted her current presenting complaints. A CT abdomen scan with contrast was reported as normal. Three months later, an abdomen ultrasound for evaluation of right upper quadrant pain and intractable vomiting, showed a liver mass. MRI revealed a contrast enhancing 3.1x2.1x1.8 cm lesion in liver segment 6 and 7. Her plasma Glucagon concentration, which had been undetectable when last checked in 2007, was 382 (N: &amp;lt; 80 pg/ml). CT-guided needle biopsy of the liver lesion confirmed a well differentiated neuroendocrine tumor, immunohistochemically positive for somatostatin receptor 2 (SSTR2A), Islet-1 and PAX6, with low mitotic count and Ki-67 proliferation index of 0.45%. Gallium-68 DOTATATE-PET scan showed a single avid hepatic metastasis, with no other evidence of somatostatin receptor expressing tumor. She was initially started on a combination of short-acting Octreotide 100 mcg TID and monthly 20 mg Sandostatin LAR injections for symptomatic relief. Zinc copper 100 mg capsules were prescribed with significant improvement of skin rash and glossitis within 2-4 months. Repeat MRI abdomen at 3 months and 6 months showed a stable single liver lesion without evidence of additional metastasis. She has continued annual clinic visits and abdomen MRI follow up with stable imaging findings at 3 years. Percutaneous ablation, trans hepatic arterial embolization and surgical resection were discussed, but the patient preferred a more conservative approach of monthly octreotide LAR, which she tolerated well, and which resolved her symptoms. Glucagonoma syndrome presents classically with 5D’s: Dermatitis (Necrolytic Migratory Erythema), DVTs, Diabetes mellitus, Depression, Diarrhea. The National Comprehensive Cancer Network guidelines recommend monitoring glucagonoma patients post-resection for up to 10 years with clinical evaluation, glucagon levels every 6-12 months and imaging studies as clinically indicated. Our case illustrates that recurrence can occur after 30 years from initial resection and that longer surveillance should be considered. Presentation: 6/3/2024

A Successful Case of Using a New Method of Surgical Treatment of Patients with Transsphincteric Pararectal Fistulas

INTRODUCTION: Surgical treatment of high transsphincteric and extrasphincteric pararectal fistulas (PFs) is one of the unsolved problems of modern coloproctological practice. Currently, there is no uniform approach in treatment of these kinds of PFs. AIM: To present a clinical case of successful application of the developed method of treatment of high transsphincteric PFs using resorbable АПТОС® threads with notches and antibacterial coating. The paper presents a case of application of the developed method for the treatment of high transsphincteric PFs using resorbable АПТОС® threads with notches and antibacterial coating in a patient admitted to a surgical department on a planned basis with complaints of the presence of a skin defect in the perianal area with permanent purulent discharge, periodic elevation of body temperature to 37.5°С–38.0°С accompanied by pain in the anus area. Detailed description of surgical intervention method is given. Within the first 3 days after the surgical intervention, low-grade body temperature persisted (37.3°С–37.5°С). The pain syndrome was most pronounced throughout the first postoperative day, in the following days analgesics were not required. On the 7th day, the patient was discharged in satisfactory condition under supervision of a surgeon at the local clinic. On the control examinations at 1 and 6 months, no data on recurrence, anal incontinence were obtained. CONCLUSION: The presented clinical case demonstrates reasonability and effectiveness of the method developed by authors for surgical treatment of high transsphincteric PFs with use of resorbable АПТОС® threads with notches and antibacterial coating.

Differentiating clinical characteristics of perianal inflammatory bowel disease from perianal hidradenitis suppurativa

AbstractBackgroundPerianal draining tunnels in hidradenitis suppurativa (HS) and perianal fistulizing inflammatory bowel disease (IBD) present diagnostic and management dilemmas.MethodsWe conducted a retrospective chart review of patients with perianal disease evaluated at Mayo Clinic from January 1, 1998, through July 31, 2021. Patients' demographic and clinical data were extracted, and 28 clinical features were collected. After experimenting with several machine learning techniques, random forests were used to select the 15 most important clinical features to construct the diagnostic prediction model to distinguish perianal HS from fistulizing perianal IBD.ResultsA total of 263 patients were included (98 with HS, 100 with IBD, and 65 with both IBD and HS). Patients with HS had a higher mean body mass index, a higher smoking rate, and more commonly showed cutaneous manifestations of tunnels and comedones, while fistulas, abscesses, induration, anal tags, ulcers, and anal fissures were more common in patients with IBD. In addition to having lesions in the perianal area, patients with IBD often had lesions in the buttocks and perineum, while those with HS had additional lesions in the axillae and groin. Among the statistically significant features, the 15 most important were identified by random forest: fistula, tunnel, digestive symptom, knife‐cut ulcer, perineum, body mass index, age, axilla, abscess, tags, smoking, groin, genital cutaneous edema, erythema, and bilateral/unilateral.ConclusionsThe results of this study may help differentiate perianal lesions, especially perineal HS and fistulizing perineal IBD, and provide promise for a better therapeutic outcome.

Case report: is necrotizing fasciitis in a rectal cancer patient after targeted systemic therapy related to the tumor site? - evidence from a hepatocellular carcinoma patient

Necrotizing fasciitis (NF) is a rare and life-threatening serious infectious disease, characterized by acute onset and rapid progress, leading to extensive necrosis of skin, soft tissue as well as fascia by a variety of aerobic and anaerobic bacteria, localized on external genitalia, scrotum, groin and perianal areas in males. There exist numerous common etiologies for NF, yet NF induced by malignant neoplasms is exceedingly rare. Several studies have reported that NF may be associated with tumor site (rectal/sigmoid colon cancer) and blood supply dysfunction caused by targeted therapy drugs (bevacizumab, aflibercept, ramucirumab). The perforation of colorectal cancer poses a unique risk factor for NF. However, in our two cases, the patient with rectal cancer received CapeOX (oxaliplatin + capecitabine) + bevacizumab + tislelizumab for 3 cycles without perforation but did develop NF. One month after debridement, the patient continued immunotherapy with tislelizumab alone for the fourth cycle and maintained for an additional 3 cycles without any recurrence of NF. Therefore, does the occurrence of NF correlate with the tumor site (rectum) and targeted immunotherapy? Another patient with hepatocellular carcinoma also developed NF after receiving 2 cycles of lenvatinib + sintilimab treatment. The third cycle of sintilimab immunotherapy was administered on the 13th day after operation, which was subsequently maintained for an additional 2 cycles without recurrence of NF. The absence of a direct correlation between hepatocellular carcinoma and rectal tumor location as well as immunotherapy, suggests that NF may be closely linked to targeted therapy.

Prognostic factors and clinical outcomes in Fournier’s Gangrene: a retrospective study of 35 patients

BackgroundFournier’s gangrene is a severe form of infectious necrotizing fasciitis affecting the perineum, perianal, and genital areas; it is associated with substantial morbidity and mortality. Hence, it is important to identify prognostic factors that can predict clinical outcomes and guide treatment strategies. Thus, our study aimed to analyze patient characteristics and determine prognostic factors affecting clinical outcomes in Fournier’s gangrene.MethodsThis retrospective study involved examining medical records spanning 18 years for patients with Fournier’s gangrene at our institution. Considering the exclusion criteria, data from 35 patients were included in this study.ResultsA total of 35 patients were included in the analysis. The mean age of the patients showed no statistically significant difference between the survivor and non-survivor groups. The Charlson Comorbidity Index, American Society of Anesthesiologists score, and Acute Physiology and Chronic Health Evaluation II score were not significantly different between the two groups. Notably, the initial Sequential Organ Failure Assessment score was significantly higher in the non-survivor group than that in the survivor group. The overall in-hospital mortality rate was 17.1%. Moreover, the prevalence of multidrug resistant bacterial infection was markedly higher in the non-survivor group than that in the survivor group. Coagulation dysfunction was significantly more prevalent in the non-survivor group than that in the survivor group, and had the most significant impact on in-hospital mortality. A multivariable logistic regression analysis identified multidrug resistant bacterial infection to be independently associated with high in-hospital mortality.ConclusionsCoagulation dysfunction and multidrug resistant bacterial infection were identified as independent negative prognostic factors, highlighting the need for prompt monitoring and proactive strategies against Fournier’s gangrene.

Fournier’s Gangrene: clinical case review and analysis of risk factors for mortality

BackgroundFournier’s Gangrene is a severe surgical infectious disease, and various risk factors can increase its mortality rate. The purpose of this study is to retrospectively analyze the clinical characteristics and laboratory data of Fournier’s Gangrene patients, followed by an analysis of mortality-related risk factors. This study has no secondary objectives.MethodsThis study included 46 hospitalized patients diagnosed with Fournier’s Gangrene at Suzhou Traditional Chinese Medicine Hospital from December 2013 to March 2024. Clinical data for all patients were extracted from the electronic medical records system. The collected data included gender, age, duration of illness, length of hospital stay, sites of infection involvement, comorbidities, white blood cell count, hematocrit, albumin, blood glucose, creatinine, serum sodium, serum potassium upon admission, microbial culture results, and patient outcomes (survival/death). The Simplified Fournier Gangrene Severe Index (SFGSI) was used to score all patients. Patients were categorized into survival and death groups based on clinical outcomes. Differences between categorical variables were compared using the χ² test or Fisher’s exact test. Differences between numerical variables were compared using Student’s t-test or the Mann-Whitney U test. Binary logistic regression was employed to analyze the risk factors for mortality in Fournier’s Gangrene.ResultsAmong the 46 Fournier’s Gangrene patients, 39 were male (84.8%) and 7 were female (15.2%). The age ranged from 17 to 86 years, with a median age of 61 years. Fourteen cases (30.4%) were confined to the perianal area, 26 cases (56.5%) had fascial necrosis involving the perianal, perineal, and genital regions, while 6 cases (13.0%) extended to the abdominal wall. At a 3-month postoperative follow-up, 43 patients (93.5%) survived, while 3 patients (6.5%) died shortly after admission due to severe illness. Based on the outcome, patients were divided into survival and death groups with 43 and 3 cases, respectively. Significant differences were observed between the two groups in terms of age (P<0.05), extension to the abdominal wall (P<0.01), hematocrit (P<0.01), albumin (P<0.01), SFGSI (P<0.01), and SFGSI>2 (P<0.01). Binary logistic regression analysis indicated that decreased hematocrit was an independent risk factor for mortality in Fournier’s Gangrene patients.ConclusionThis study provides a detailed analysis of the clinical characteristics and risk factors for mortality in Fournier’s Gangrene patients. The primary outcome of this study is that a decreased hematocrit is an independent risk factor for predicting mortality in FG patients. These findings offer valuable prognostic insights for clinicians, underscoring the importance of early identification and correction of reduced hematocrit to improve patient outcomes and survival rates.

EP264 - Dermatofibrosarcoma protuberance of the perianal region

Abstract Introduction Dermatofibrosarcoma protuberans (DFSP) is a rare low-grade sarcoma affecting dermis and subcutaneous fat. Typically presents as slow-growing lump on the trunk, extremities or head and neck.(1) It can be locally aggressive with a high recurrence rate.(2) Only 6 reported cases of DFSP in peri-anal region. Case Description A 26-year-old male presented with slow-growing peri-anal lump for over a year with intermittent localised pain and episodes of bleeding. No other symptoms or trauma to peri-anal area noted. No relevant medical or surgical history. Examination revealed an irreducible two-by-five by one-centimetre semi-pedunculated perianal lump extending from the seven o’clock to eleven o’clock position. It was firm and tethered to the skin. Case Description Flexible sigmoidoscopy was normal. Excision biopsy histology reported diffuse infiltration of spindle cells with storiform pattern of growth without clear margins. Immunohistochemistry analysis expressed CD34 with minimal focal expression of SMA and variable Ki-67 proliferation indexed up to 15-20% in most active areas. SOX10, S100, desmin, factor XIIIA, MNF116 and CD31 were negative. Diagnosis was DFSP. Local lower gastrointestinal multi-disciplinary arranged urgent imaging and referral to tertiary centre. Magnetic resonance imaging of the pelvis identified no definite underlying localised restricted diffusion or solid enhancing nodule. Wide local excision at tertiary centre with histopathology confirmed clear margins. Conclusion Patient is under follow-up locally and at the tertiary. Urgency and a singular episode of stool incontinence was reported at two-weeks follow-up which subsequently normalised. He is currently under 3-6 monthly reviews with repeat MRI prior to next appointment. Patient has returned to normal activities.

Dermatoscopic features of vulvar lichen sclerosus in children: A retrospective study.

To explore the dermoscopic features of lichen sclerosus in different parts of the external genitalia in children. A retrospective analysis of the dermoscopic features of 42 female children with vulvar lichen sclerosus treated in the Department of Dermatology of Shanxi Children's Hospital from January 2020 to May 2023. Among the 42 female children, aged 3-14 years (mean: 7.24 ± 2.43 years), the duration of vulvar lichen sclerosus ranged from 3 months to 2 years (mean: 9.83 ± 4.93 months). Clinical lesions occurred in the labia minora in 18 cases (42.9%), labia majora in 38 cases (90.5%), posterior fourchette in 36 cases (85.7%), perianal area in 13 cases (31.0%), anterior fourchette in 17 cases (40.5%), clitoris in seven cases (16.7%), and interlabial sulcus in 11 cases (26.2%). Dermoscopic findings common in the labia majora included follicular keratotic plugs, cloverleaf-like structures, comedo-like openings, and linear vessels (p < .05); however, purple-red globules and patches and white linear streaks were more common in the posterior fourchette (p < .05), whereas dotted vessels were more common in the labia minora (p < .05). Common dermoscopic findings in pediatric vulvar lichen sclerosus were yellow-white structureless areas, white linear streaks, follicular keratotic plugs, and cloverleaf-like structures; yellow-white structureless areas and white linear streaks showed the highest specificity. The dermoscopic findings varied among different affected areas, which provides a basis for further understanding of the characteristics of different sites of vulvar lichen sclerosus in the pediatric population.

Clinicopathological Findings and Comprehensive Review of Buschke-Lowenstein Tumors Based on a Case Study.

The Buschke-Löwenstein tumor (BLT), also known as giant condyloma acuminatum, is a rare, exophytic tumor, arising from pre-existing warty lesions associated with human papillomavirus (HPV) infection, particularly strains 6 and 11, which are considered to have low oncogenic potential. BLT presents as a large, cauliflower-like growth typically affecting the penis, vulva, vagina, perineum, scrotum, anus, and perianal area. Despite being a benign lesion, BLT is locally aggressive with a high recurrence rate, and can potentially undergo malignant transformation into squamous cell carcinoma, contributing to an overall mortality rate of 20-30%. The primary treatment is complete surgical excision with wide margins, frequently requiring complex reconstructive techniques for defect coverage. We report on a 68-year-old patient, with multiple comorbidities, who presented with a two-year history of a large exophytic tumor in the genital region, affecting the penis, along with progressive erectile dysfunction and urinary problems. The tumor was surgically excised with oncological safety margins, and reconstruction was performed using advancement and rotation flaps from the scrotum and intact penile skin. Histopathological examination confirmed the diagnosis of Giant Condyloma (Buschke-Löwenstein tumor), showing acanthosis, papillomatosis, parakeratosis, and koilocytic cell collections, with positive immunohistochemical staining for p16, p63, and ki67. Postoperatively, the patient had a good clinical outcome and a complete surgical cure. This case highlights the critical need for timely intervention and comprehensive management strategies in treating giant condyloma, given its potential for local invasion and substantial impacts on patient quality of life. Early diagnosis and thorough surgical excision are crucial for effective management and to reduce the high recurrence, morbidity and malignant transformation risk associated with this condition.

Analgesic Efficacy of EMLA Cream Among Patients Undergoing Hemorrhoidectomy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Post-hemorrhoidectomy pain is a concerning complication for patients and doctors, mainly due to perianal skin dissection and the complex innervation of the area. Therefore, our aim is to explore the analgesic efficacy and safety of EMLA cream among patients undergoing hemorrhoidectomy. We conducted a comprehensive search of five electronic databases (PubMed, Scopus, Web of Science, Embase, Cochrane) from inception until July 6, 2024. A risk of bias assessment was performed using the Risk of Bias Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB-2). Only randomized controlled trials (RCTs) were included. Our outcomes of interest were pain assessment using the Visual Analogue Scale (VAS) score, patient satisfaction, meperidine dosage, frequency of meperidine requests, and single urinary catheterization. We used RevMan software to conduct the statistical analysis. Dichotomous data were pooled as relative risk (RR), while continuous data were pooled as mean difference (MD). Four RCTs were included in our review. Two RCTs showed a low overall risk of bias, while one RCT showed a high risk, and the last one showed some concerns. Our analysis showed a significant difference between the two groups, favoring the EMLA group over the control group, upon arrival at the recovery room and at night on the day of the operation (MD=-1.76, 95% CI (-3.17, -0.36), p=0.01 and MD=-1.65, 95% CI (-2.48, -0.81), p=0.0001, respectively). However, there was no significant difference between the two groups in the morning on the day after the operation (MD=-0.9, 95% CI (-2.02, 0.21), p=0.11). Moreover, patients who used EMLA cream reported increased patient satisfaction compared to those who did not. However, there was no significant difference between both groups in terms of the use of urinary catheterizations. In conclusion, our study showed that applying EMLA cream over the perianal area after hemorrhoidectomy can effectively reduce postoperative pain and decrease the required opioid dosage and patient requests. This ultimately leads to increased patient satisfaction. However, further studies are still required to confirm these findings.

Audit of Genito-Anal Injuries in male and female sexual abuse cases - A retrospective study.

Background: Sexual assault is a global issue wherein timely examination of sexual assault victims by medico-legal officers and an understanding of the characteristics and factors influencing their injuries have a crucial impact on medico-legal evidence collection and its use in the court. Genital injury findings improve the level of justice for victims, but the lack of injury does not negate the possibility of sexual violence incurred on the victim. The following study describes in great detail the different factors associated with injury characteristics and the medico-legal importance of all these factors. Methodology: It was a retrospective descriptive study conducted at the Forensic Medicine Department of King Edward Medical University, Lahore, Pakistan. All the cases included that fulfill the predefined inclusion criteria were included. A record chart was designed, and six years’ data was recorded in it from the medical records of the medico-legal clinic. It was entered and edited manually. Methods used to prevent data entry errors included double entry and validation following data entry Difference of proportions between variables, where appropriate, has been calculated by Pearson Chi-Square test and Fischer Exact test at 95% confidence interval. Data were analyzed using SPSS v23. All procedures performed in this study involving human participants were following the ethical standards of the institutional and/or national research committee and the Helsinki declaration. Results: Genito anal injury was present in 28.2% cases and was absent in 71.8% cases. Most of the victims were aged 11 to 15 years. The most common injury in the victims was a tear. In females, the most common injury site was the vagina, while the perianal area was the most injured site in males. There was a significant relation (p&lt;0.05) between type and site of injury, gender, site of injury, and prior sexual intercourse experience and prevalence rate of injury. Conclusion: This study concludes that the presence of injuries in the Genito anal area is suggestive of sexual assault and provides useful court evidence.

Development of Fournier's gangrene after chemotherapy for the recurrence of testicular cancer despite the absence of anorectal lesions: A case report.

Fournier's gangrene usually occurs when a specific bacterium intrudes into soft tissue, causing a wound or tumor. We encountered a patient with Fournier's gangrene due to severe myelosuppression after chemotherapy, despite the absence of an initial lesion on the anus and rectum. A 54-year-old man with a left testicular cancer recurrence had undergone chemotherapy. He had asymptomatic hepatitis and high hepatitis B virus DNA levels, which were normalized by administering tenofovir alafenamide fumarate. Twelve days after the start of chemotherapy, he complained of severe pain around the anus. The following day, he went into septic shock. Visual inspection showed dark purple skin discoloration on the left side of the anus. Laboratory data revealed severe neutropenia. Computed tomography showed a high density of soft tissue on the left side of the anus and gas bubbles in the left femoral ring. We diagnosed the patient with Fournier's gangrene due to a severe immunosuppressive state resulting from chemotherapy. We emergently removed necrotic tissue to the fullest extent possible. However, because the patient was in severe sepsis status, careful management in the intensive care unit was required for 32 days. After the first emergency operation, we performed several additional excisions. Finally, 391 days after the initial surgery, the patient was discharged from our hospital. The tumor has not recurred, and he is under outpatient observation in the urology department. Fournier's gangrene should be considered in patients who are in a severe myelosuppressive state due to chemotherapy, have normal hepatitis B virus DNA levels but high hepatitis B surface antigen after tenofovir administration, complain of severe pain in the perianal area, and have a dark purple skin discoloration around the anus, despite having no initial anorectal lesions.

Comparison of diagnostic methods for laboratory diagnosis of the zoonotic tapeworm Dipylidium caninum in cats

The tapeworm Dipylidium caninum is the most widely distributed cestode infecting dogs, cats, and sometimes humans, worldwide. The diagnosis of the infection caused by D. caninum is achieved via the visualization of proglottids in feces or with traditional microscopic tests, but both lack sensitivity. The present study has evaluated and compared the diagnostic performance of a PCR protocol on different feline biological samples to detect D. caninum. A sample of feces, a Scotch tape test from the perianal area, and a rectal swab were collected from a total of 100 privately owned cats from Italy and Greece. All fecal samples were subjected to macroscopic examination and to floatation. Based on the results of the above tests the cats were divided in three groups, i.e. (i) cats positive for D. caninum (regardless of positivity for other endoparasites (Group A; n = 50 cats), (ii) cats negative for D. caninum but infected by other helminths (Group B; n = 25 cats), and (iii) cats negative for intestinal endoparasites (Group C; n = 25 cats). For each sample, the DNA was extracted from feces, floatation supernatant, Scotch tape test and rectal swabs and subjected to PCR. For 33 cats from Group A, at least one sample type scored positive at PCR. Of these, all were PCR-positive in the floatation aliquot, while nine and one cats were positive by PCR on feces and Scotch tape test, respectively. Swabs were negative by PCR for all the cats. None of the samples from cats of Groups B and C was positive by any PCR. Sequences obtained from amplicons generated from samples of cats enrolled in Italy had 99–100 % identity with the recently described D. caninum feline genotype. The data presented here suggest that PCR could be a useful tool for diagnosing D. caninum infections, under certain circumstances, e.g. when proglottids are unidentified, unseen or overlooked, even though it has limitations, e.g. false negative results due to fecal PCR inhibitors, uneven distribution of parasitic elements, or to intermittent proglottid and/or egg shedding.

Fistula in Ano is a chronic inflammatory condition having a tubular structure with opening in the Anorectal canal at one end and surface of perineum or perianal skin on the other end. Any opening in perianal area with chronic pus discharge indicates fistulous tract. Prolong sitting, unhygienic condition, obesity, repeated irritation due to hair may increase the risk of occurrence. In Ayurveda it is correlated with Bhagandar and Acharya Sushruta mentioned five types of Bhagandar. He had explained Shastra karma along with Kshar karma and Bheshaja chikitsa for treatment. Here a case of fistula in Ano in a 21 years male patient was examined in Shalya OPD and treated with Ksharsutra, considering it as an ideal procedure in treatment of Bhagandar as it cuts and curettes the unhealthy tissue present inside the fistulous tract. An Anal fistula can heal more quickly after taking a sitz bath. The warm water helps ease pain and suffering while also reducing inflammation. Moreover, it can aid in maintaining cleanliness in the affected area, lowering the chance of infection. Abhayarishta and Kumaryasav can be used as a laxative to help manage constipation.

Survey of pain and stigma experiences in people diagnosed with mpox in Baltimore, Maryland during 2022 global outbreak.

A high prevalence of mpox in men who have sex with men and in people with HIV, plus visually striking and contagious lesions, have raised concerns for mpox stigma. 24 PCR-confirmed mpox patients were surveyed over the course of three months, utilizing an mpox stigma scale adapted from the HIV Stigma Scale plus assessment of pain, analgesic efficacy, and healthcare experiences. Participants were cis-male (100%), with male sexual partners (96%), mostly African-American (88%), and living with HIV (79%). Patients answered 4-16 of 24 (mean 10) stigma questions affirmatively, particularly related to negative effects of mpox on the LGBTQ community. 79% reported pain, most commonly of limbs and perianal area, with perianal pain being rated most severe. The most effective pain relief occurred with opioids (100% major relief, n = 2) and tecovirimat (63% major relief, 25% moderate, n = 16). Patients were satisfied with care provided at the studied clinics, but had negative experiences at all other mentioned sites.
