Comparison of etiological and physiological characteristics of fecal incontinence in men and women.

Fecal incontinence (FI) is often underreported and underestimated in men. Our aims were to clarify the causes and the physiological characteristics of FI in men and to underline the differences between etiological and physiological factors in men and women diagnosed with FI. The study cohort encompassed 200 men and 200 women who underwent anatomical and physiological evaluation for FI in a tertiary referral center specializing in pelvic floor disorders. All patients underwent endoanal ultrasound and anorectal manometry. Evacuation proctography was performed in some patients. Demographic, medical, anatomical, and physiological parameters were compared between the two study groups. Urge incontinence was the most frequent type of FI in both genders. In men, anal fistula, history of anal surgeries, rectal tumors, and pelvic radiotherapy were common etiologic factors, whereas history of pelvic surgeries was more common in women. Associated urinary incontinence was reported more frequently by women. External anal sphincter defects, usually anterior, were more common in women (M: 1.5%, F: 24%, P < 0.0001), whereas internal anal sphincter defect prevalence was similar in men and women (M: 6%, F: 12%, P = 0.19). Decreased resting and squeeze pressures were less common in men (M: 29%, F: 46%, P < 0.0001: M: 44%, F: 66%, P < 0.0001). The incidence of rectal hyposensitivity was higher in men (M: 11.1%, F: 2.8%, P < 0.0001), whereas rectal hypersensitivity was higher in women (M: 5.8%, F: 10.8%, P < 0.0001). Anorectal dyssynergia was more common in men (M: 66%, F: 37%, P < 0.0001). Significantly different etiological factors and physiological characteristics for FI were found in men. Acknowledging these differences is significant and may yield better treatment options.NEW & NOTEWORTHY Fecal incontinence (FI) in men has different etiological factors when compared with women. The prevalence of internal anal sphincter defect among men with FI was similar to women. Different manometric measurements were found among men with FI: decreased anal pressures were less common among men, whereas rectal hyposensitivity and anorectal dyssynergia were more common among men.

A Prospective, Single-Arm Study to Evaluate the Safety and Efficacy of an Autologous Blood Clot Product in the Treatment of Anal Fistula.

BACKGROUND: Surgical treatment of complex perianal fistula is technically challenging, associated with risk of failure, and may require multiple procedures. In recent years, several biologic agents have been developed for permanently eradicating anal fistulous disease with variable success. In this study, the treatment is an autologous whole-blood product created from the patients' blood. It forms a provisional matrix that was found to be safe and effective in healing acute and chronic cutaneous wounds. OBJECTIVE: The study aimed to assess the efficacy and safety of an autologous blood clot product as a treatment for transsphincteric perianal fistulas. DESIGN: A prospective single-arm study. SETTINGS: A single tertiary medical center. PATIENTS: Patients with simple or complex transsphincteric fistulas confirmed by MRI were included in the study. Cause was either cryptoglandular or Crohn's disease related (in the absence of active luminal bowel disease). INTERVENTION: The outpatient procedure was performed under general anesthesia and consisted of: 1) physical debridement and cleansing of the fistula tract; 2) suture closure of the internal opening; and 3) instillation of the autologous blood clot product into the entire tract. MAIN OUTCOME MEASURES: Safety and efficacy at 6- and 12-months after surgery. RESULTS: Fifty-three patients (77% men) with a median age of 42 (20-72) years were included in the study. Three patients withdrew consent, and 1 patient was lost to follow-up. At the time of this interim analysis, 49 and 33 patients completed the 6- and 12-month follow-up period. Thirty-four of the 49 patients achieved complete healing (69%) at 6 months, but 20 of the 33 patients (60%) achieved healing after 1 year. All patients who achieved healing at 6 months remained healed at the 1-year mark. In a subgroup analysis of patients with Crohn's disease, 7 of 9 patients completed 1-year follow-up, with 5 patients (71%) achieving clinical remission. No major side effects or postoperative complications were noted, but 2 adverse events occurred (admission for pain control and coronavirus 2019 infection). LIMITATIONS: Noncomparative single-arm pilot study. CONCLUSIONS: Treatment with an autologous blood clot product in perianal fistular disease was found to be feasible and safe, with an acceptable healing rate in both cryptoglandular and Crohn's disease fistula-in-ano. Further comparative assessment is required to determine its potential role in the treatment paradigm of fistula-in-ano. See Video Abstract .

En los últimos años, se han desarrollado varios agentes biológicos con el fin de erradicar permanentemente la enfermedad fistulosa anal con éxito variable. El tratamiento RD2-Ver.02 es un producto de sangre total autólogo creado a partir de la sangre de los pacientes, que forma una matriz provisional que resultó segura y eficaz para curar heridas cutáneas agudas y crónicas.OBJETIVO:Evaluar la eficacia y seguridad de RD2-Ver.02 como tratamiento para las fístulas perianales transesfinterianas.DISEÑO:Un estudio prospectivo de un solo brazo.LUGARES:Un único centro médico terciario.PACIENTES:Se incluyeron en el estudio pacientes con fístulas transesfinterianas simples o complejas confirmadas mediante resonancia magnética. La etiología fue criptoglandular o relacionada con la enfermedad de Crohn (en ausencia de enfermedad intestinal luminal activa).INTERVENCIÓN:El procedimiento ambulatorio se realizó bajo anestesia general y consistió en: 1) desbridamiento físico y limpieza del trayecto fistuloso; 2) cierre con sutura de la abertura interna; y 3) instilación de RD2-Ver.02 en todo el tracto.PRINCIPALES MEDIDAS DE VALORACIÓN:Seguridad y eficacia a los 6 y 12 meses después de la cirugía.RESULTADOS:Se incluyeron en el estudio 53 pacientes (77% varones) con una mediana de edad de 42 (20-72) años. Tres pacientes retiraron su consentimiento y un paciente se perdió durante el seguimiento. En el momento de este análisis intermedio, 49 y 33 pacientes completaron el período de seguimiento de 6 y 12 meses, respectivamente. Treinta y cuatro (34) pacientes lograron una curación completa (69%) a los 6 meses, mientras que 20 de 33 pacientes (60%) lograron una curación después de un año. Todos los pacientes que lograron la curación a los 6 meses permanecieron curados al año. En un análisis de subgrupos de pacientes con enfermedad de Crohn, 7/9 pacientes completaron un seguimiento de un año y 5 pacientes (71%) alcanzaron la remisión clínica. No se observaron efectos secundarios importantes ni complicaciones postoperatorias, mientras que ocurrieron 2 eventos adversos (ingreso para control del dolor e infección por COVID-19).LIMITACIONES:Estudio piloto no comparativo de un solo brazo.CONCLUSIONES:Se encontró que el tratamiento con RD2-Ver.02 en la enfermedad fístula perianal es factible y seguro, con una tasa de curación aceptable tanto en la fístula criptoglandular como en la de Crohn en el ano. Se requiere una evaluación comparativa adicional para determinar su papel potencial en el paradigma de tratamiento de la fístula anal. (Pre-proofed version ).

The value of CA125 in predicting acute complicated colonic diverticulitis.

BACKGROUND: CA125 is a widely used serum marker for epithelial ovarian cancer which levels may also rise in benign conditions involving peritoneal irritation. We aimed to determine if serum CA125 levels can predict disease severity in patients presenting with acute diverticulitis. METHODS: We conducted a single-center prospective observational study, analyzing CA125 serum levels in patients who presented to the emergency department with computerized tomography-proven acute left-sided colonic diverticulitis. Univariate, multivariate, and receiver operating characteristic (ROC) analyses were used to correlate CA125 serum levels at time of initial presentation with the primary outcome (complicated diverticulitis) and secondary clinical outcomes (need for urgent intervention, length of hospital stay (LOS) and readmission rates). RESULTS: One hundred and fifty-one patients were enrolled between January 2018 and July 2020 (66.9% females, median age 61 years). Twenty-five patients (16.5%) presented with complicated diverticulitis. CA125 levels were significantly higher among patients with complicated (median: 16 (7-159) u/ml) vs. uncomplicated (8 (3-39) u/ml) diverticulitis (p < 0.001) and also correlated with the Hinchey severity class (p < 0.001). Higher CA125 levels upon admission were associated with a longer LOS and a greater chance to undergo invasive procedure during the hospitalization. In patients with a measurable intra-abdominal abscess (n = 24), CA125 levels were correlated with the size of the abscess (Spearman's r = 0.46, p = 0.02). On ROC analysis to predict complicated diverticulitis, the area under the curve (AUC) for CA125 (AUC = 0.82) was bigger than for the leukocyte count (AUC = 0.53), body temperature (AUC = 0.59), and neutrophil-lymphocyte ratio (AUC = 0.70) - all p values < 0.05. On multivariate analysis of factors available at presentation, CA125 was found to be the only independent predictor of complicated diverticulitis (OR 1.12 (95% CI 1.06-1.19), p < 0.001). CONCLUSIONS: The results from this feasibility study suggest that CA125 may accurately discriminate between simple and complicated diverticulitis, meriting further prospective investigation.

Readmission with acute kidney injury following ileostomy: patterns and predictors of a common phenomenon.

PURPOSE: Ileostomy is associated with various complications, often necessitating rehospitalization. High-output ileostomy is common and may lead to acute kidney injury (AKI). Here we describe the temporal pattern of readmission with AKI following ileostomy formation and identify risk factors. METHODS: Patients that underwent formation of ileostomy between 2008 and 2021 were included in this study. Readmission with AKI with high output ileostomy was defined as readmission with serum creatinine > 1.5-fold compared to the level at discharge or latest baseline (at least stage-1 AKI according to Kidney Disease: Improving Global Outcome (KDIGO) criteria), accompanied by ileostomy output > 1000 ml in 24 h. Patient characteristics and perioperative course were assessed to identify predictors for readmission with AKI. RESULTS: Of 1191 patients who underwent ileostomy, 198 (16.6%) were readmitted with a high output stoma and AKI. The mean time to readmission with AKI was 98.97 ± 156.36 days. Eighty-six patients (43.4%) had early readmission (within 30 days), and 66 (33%) were readmitted after more than 90 days. Over 90% of patients had more than one readmission, and 110 patients (55%) had 5 or more. Patient-related predictors for readmission with AKI were age > 65, body mass index > 30 kg/m2, and hypertension. Factors related to the postoperative course were AKI with creatinine > 2 mg/dl, postoperative hemoglobin < 8 g/dl or blood transfusion, albumin < 20 g/dl, high output stoma and need for loperamide, and length of hospital stay > 20 days. Factors related to early versus late readmissions and multiple readmissions were also analyzed. CONCLUSIONS: Readmission with AKI following ileostomy formation is a consequential event with distinct risk factors. Acknowledging these risk factors is the foundation for designing interventions aiming to reduce frequency of AKI readmissions in predisposed patient populations.

The association between vacuum-assisted vaginal delivery and anal sphincter injury.

INTRODUCTION: Vacuum-assisted vaginal delivery (VAVD) is considered a major risk factor for obstetric anal sphincter injuries (OASIS). However, it is difficult to estimate its true contribution to the occurrence of OASIS, as its performance may be confounded by other determinants. Therefore, we aimed to evaluate the association of VAVD with OASIS among primiparous women compared to SVD. METHODS: A retrospective cohort study including all primiparous women who vaginally delivered a cephalic singleton gestation during the years 2011 to 2020. As VAVDs were not performed before 34 gestational weeks, we capped the cohort at this gestational age. Women were allocated into two groups: VAVDs and spontaneous vaginal deliveries (SVD). We compared women with OASIS to those without and performed a multivariate analysis including factors that were found significant in the univariate analysis. We further divided the whole cohort into different subcategories. The primary outcome was the rate of OASIS in VAVD compared to SVD. RESULTS: Overall, 23,272 primiparous vaginal deliveries were available for evaluation. Of these, 3595 delivered by VAVD and 19,677 delivered spontaneously. OASIS occurred in 421 (1.8%) of the deliveries. OASIS were more common in VAVDs than in SVDs [83 (2.3%) vs. 338 (1.7%), respectively, OR (95% CI) 1.35 (1.06-1.72), p = 0.01]. After multivariate regression analysis, OASIS were not found to be independently associated with the mode of delivery [aOR 1.21 (95% CI) 0.88-1.68, P = 0.23]. In a categorical analysis of OASIS rates by risk factors and mode of delivery, VAVD was not associated with an increase in OASIS among women giving birth to neonates weighing > 3500 g compared to SVD [OR (95% CI) 1.02 (0.65-1.62), P = 0.90]. CONCLUSION: Among primiparous women VAVD did not increase the risk of OASIS compared to SVD.

Risk of anal sphincter injury in trial of labor post cesarean section.

INTRODUCTION: We wanted to evaluate whether secundiparas who achieved vaginal birth after cesarean (VBAC) were at an increased risk for obstetric anal sphincter injury (OASI) compared to primiparas who delivered vaginally, with a stratification by the mode of delivery-spontaneous or operative vaginal delivery. MATERIAL AND METHODS: We conducted a retrospective cohort study of primiparous women who delivered by vacuum-assisted delivery between March 2011 and June 2019. Primiparas delivering vaginally and secundiparas undergoing VBAC were compared. The cohort was further stratified into two categories: spontaneous vaginal delivery and operative vaginal delivery. RESULTS: Overall, 23 822 primiparas who delivered vaginally and 1596 secundiparas who underwent VBAC were analyzed. Operative vaginal delivery was performed in 4561 deliveries. OASI rate did not differ between the VBAC and primipara groups (1.3% vs 1.8%, P = .142). A total of 20 857 women delivered by spontaneous vaginal delivery, among them 1180 (5.7%) women were secundiparas and 19 677 (94.3%) were primiparas. OASI rate was comparable between the secundiparas undergoing VBAC and primiparas delivering vaginally (17 [1.4%] vs 338 [1.7%], P = .436). A total of 4561 women delivered by operative vaginal delivery, among them 416 (9.1%) were secundiparas and 4145 (90.9%) were primiparas. The rate of operative vaginal deliveries was higher among the VBAC group compared with the primipara group (6.1% vs 17.4%, P < .001). However, women undergoing successful VBAC had lower rates of OASI compared with primiparas (3 [0.7%] vs 96 [2.3%]; odds ratio [OR] 0.30, 95% CI 0.09-0.97, P = .032). After multivariate logistic regression including all statistically significant factors, OASI was not associated with VBAC in spontaneous or operative vaginal deliveries (adjusted OR 0.85, 95% CI 0.51-1.40 and 0.39, 95% CI 0.12-1.28, respectively). CONCLUSIONS: Secundiparas undergoing VBAC were not at a higher risk of OASI when compared with primiparas delivering vaginally, either in spontaneous or operative vaginal deliveries. This information might aid when counseling women contemplating a trial of labor after cesarean--to address their concerns regarding the risks and benefits of VBAC.

Sonographic fetal head circumference and the risk of obstetric anal sphincter injury following vaginal delivery.

INTRODUCTION: High birth weight is strongly associated with OASIS; nevertheless, it has not been determined which biometric characteristics most affect OASIS occurrence. We aimed to evaluate the association of estimated fetal head circumference with OASIS occurrence among primiparous women delivering by unassisted vaginal delivery. METHODS: A retrospective study included all primiparous women who delivered at term by spontaneous vaginal delivery from 2011-2019. Women were allocated to two groups: (1) those who experienced OASIS and (2) those who did not experience OASIS. Risk factors for OASIS were analyzed. RESULTS: Overall, 7646 women were included in the study cohort. Of those, 119/7646 (1.6%; 95% CI, 1.3-1.9%) experienced OASIS. Sonographic head circumference and birth weight did not vary between groups. Prolonged second stage was more common in the OASIS group [23 (19%) vs. 986 (13.3%), 1.58 OR (95% CI 1.003-2.51, p = 0.04)]. Absence of epidural analgesia was more common in the OASIS group [30 (25%) vs. 1197 (15.9%), 1.8 OR (95% CI 1.1-2.7, p = 0.006)]. On multivariate logistic regression analysis, the lack of epidural analgesia and duration of second stage of labor were both independently positively associated with OASIS [adjusted OR 2.67 (95% CI 1.55-4.62), p < 0.001, adjusted OR 1.23 (95% CI 1.11-1.43), p < 0.001, respectively)]. CONCLUSION: Sonographic head circumference and birth weight are not associated with OASIS occurrence among primiparous women delivering by an unassisted vaginal delivery. Prolonged second stage and the use of epidural analgesia are modifiable risk factors among these women.

Validation of the Wexner scale in a Hebrew-speaking population.

INTRODUCTION: The Cleveland Clinic Incontinence Score, known as the Wexner Score (WS), is a simple, disease-specific questionnaire for anal incontinence (AI) assessment. We aimed to translate and validate a Hebrew version of the WS. METHODS: Between November 2018 and December 2019, the WS was back translated and reviewed by a multidisciplinary pelvic floor team. The questionnaire was filled out by patients visiting the urogynecology and surgical pelvic floor clinics. Two weeks after completion, the patients were contacted using telephone surveys to assess the test-retest reliability examination. Construct validity was assessed by comparing the WS to the Colorectal-Anal Distress Inventory 8 (CRADI-8), a part of the validated Hebrew version of the Pelvic Floor Distress Inventory questionnaire (PFDI-20). RESULTS: Overall, 91 female patients completed the WS questionnaire. Eighty-five percent (n = 78) responded to the re-test WS questionnaire. A high intraclass coefficient of 0.87 was found in the WS total score, with a range from 0.82 to 0.86 for its subscales. A significant positive relationship between the Hebrew versions of the WS and CRADI-8 scores was established (r = 0.66, p < 0.0001). CONCLUSION: A new, Hebrew-translated version of the WS is a reliable and valid instrument for assessing AI.

The role of fetal head circumference in the formation of obstetric anal sphincter injuries following vacuum deliveries among primiparous women.

PURPOSE: To evaluate the association of sonographic fetal head circumference (HC) with obstetric anal sphincter injury (OASIS) occurrence among primiparous women who underwent vacuum-assisted delivery (VAD). METHODS: A retrospective study of all primiparous women who delivered at term by VAD between 2011 and 2019 and underwent ultrasound with fetal biometry within 1 week prior to delivery. Women who suffered OASIS were compared to women without OASIS. RESULTS: Overall, 74 of 3222 (2.3%) primiparous women suffered an OASIS. As compared with control, women with OASIS were younger (median 28 vs. 30 years, p = 0.001), had higher BMI (median 28.2 vs. 26.9 kg/m2, p = 0.03), and had a longer second stage of labor (median 190 vs. 168 min, p = 0.01). Fetal head circumference was larger in the OASIS group (mean 334 vs. 330 mm, p = 0.03), occiput posterior fetal head position was more prevalent (12 (16%) vs. 232 (7.4%), OR [95% CI]: 2.43 (1.29-4.57), p = 0.004), and the rate of mediolateral episiotomy performed was lower (58 (78.0%) vs. 2777 (88.2%), OR [95% CI]: 0.48 (0.27-0.85), p = 0.01). Multivariate regression modeling identified higher fetal HC (aOR [95% CI] 1.03 (1.001-1.06), p = 0.04) and occiput posterior (aOR [95% CI] 2.5 (1.16-5.71), p = 0.01) as independently positively associated with OASIS. Mediolateral episiotomy and maternal age were independently negatively associated with an OASIS (aOR [95% CI] 0.39 (0.18-0.85), p = 0.01); aOR [95% CI] 0.4 (0.17-0.60), p = 0.001). CONCLUSIONS: Sonographic large fetal HC is associated with OASIS occurrence during VAD. The only modifiable predictor of OASIS detected was mediolateral episiotomy, found to be protective against OASIS.

Breast Cancer in Men: A Single Center Experience Over a Period of 22 years.

BACKGROUND: Male breast cancer (MBC) is a rare disease that is poorly understood. Treatment protocols are widely extrapolated from breast cancer in women. OBJECTIVES: To review the experience with MBC of a single center in Israel over a period of 22 years. METHODS: This single center retrospective study evaluated all patients diagnosed with MBC over a period of 22 years (1993-2015). Data were extracted from patient medical charts and included demographics, clinical, surgical, and oncological outcomes. RESULTS: The study comprised 49 patients. Mean age at diagnosis was 64.1 ± 13.5 years. The majority were diagnosed at early stages (1A-2A) (54.4%), 30.6% were stage 3B mostly due to direct skin and nipple involvement, and 59.2% of the patients had node negative disease. All of the patients were diagnosed with invasive ductal carcinoma and 30.6% had concomitant ductal carcinoma in situ. Estrogen receptor (ER) status was predominantly positive and luminal B (HER2-) was the most common subtype. Of the patients, 18.4% were BRCA carriers. The majority of patients underwent mastectomy. Radiotherapy was delivered to 46.9% and hormonal therapy to 89.8%. Chemotherapy was administered to 42.9%. Overall survival was 79.6% with a median survival of 60.1 (2-178) months; 5- and 10-year survival was 93.9% and 79.6%, respectively. Progesterone receptor (PR)-negative patients had a significantly improved overall survival. CONCLUSIONS: MBC has increasing incidence. PR-negative status was associated with better overall survival and disease-free interval. Indications to radiotherapy and hormonal therapy need standardization and will benefit from prospective randomized control trials.

Perineal Stapled Rectal Prolapse Resection in Elderly Patients: Long-term Follow-up.

BACKGROUND: Full-thickness rectal prolapse has a significant negative impact on quality of life. The therapeutic options, specifically in elderly patients, are imperfect. Perineal stapled rectal prolapse resection is a novel operation for treating external rectal prolapse. Long-term follow-up following this procedure is lacking. In our study, we report a long-term follow-up of 30 patients, analyzing the long-term recurrence rate, morbidity, and functional outcome. OBJECTIVE: This study aimed to examine the long-term results of perineal stapled rectal resection in a population unfit for prolonged general anesthesia. DESIGN: This was a cohort study with a prospective follow-up. SETTINGS: This study was conducted at a single tertiary referral center. PATIENTS: Patients undergoing perineal stapled rectal resection from January 2010 to June 2013 were included. INTERVENTIONS: Perineal stapled rectal prolapse resection was performed. MAIN OUTCOME MEASURES: The primary outcome measured was prolapse recurrence. RESULTS: A total of 30 patients underwent the surgical intervention. The median follow-up period was 61 months (range, 37-65). No intraoperative or postoperative complications occurred. Six patients (20%) had recurrent rectal prolapse, and continence was not achieved in any of the patients. Two patients who had recurrence underwent a redo perineal stapled rectal resection. LIMITATIONS: This study was limited by the small cohort of selected patients. CONCLUSIONS: Frail patients that can only endure a short procedure under regional anesthesia should be considered for perineal stapled rectal prolapse resection. The lack of mortality and morbidity, specifically in this population, along with the low long-term recurrence rates, make this a favorable surgical alternative.

How Prevalent is Hydronephrosis Secondary to Acute Appendicitis: A Cross-Sectional Study.

BACKGROUND: Right hydronephrosis secondary to acute appendicitis is an under-reported phenomenon with only several case reports published. OBJECTIVES: To assess the incidence of this phenomenon in our database of patients diagnosed with acute appendicitis. METHODS: Data were collected on 1092 patients who underwent surgery due to acute appendicitis between 2003 and 2007 in our tertiary medical center. The data entailed demographic, surgical, and hospitalization parameters including ultrasound or computed tomography examinations and presence of right hydronephrosis prior to surgery. RESULTS: Out of 1092 patients, appendicitis was eventually diagnosed in 87.4% of the patients. Only 594 (54%) had preoperative imaging performed prior to surgery (ultrasound or computed tomography). Out of these 594 patients, 21 (3.5%) had a new right hydronephrosis diagnosed and all had appendicitis with 15/21 (71%) having a retrocecal appendix. Of those with retrocecal appendix, 10 were pregnant women (48%). Erythrocyturia was present in 15/21 patients (71%) and in 10/11 of patients (91%) after excluding those who were pregnant. No significant differences were seen in patients with hydronephrosis regarding age, hospitalization, and surgery time. In all patients, an ultrasound was performed 2 weeks after surgery demonstrating the disappearance of hydronephrosis. Median follow-up time was 41.7 months (range 14.8-118.4 months). CONCLUSIONS: Our study shows that 3.5% of our cohort had right hydronephrosis secondary to acute appendicitis. Although this presentation is very rare, physicians should be aware of this phenomenon and the risk for delayed diagnosis and treatment of acute appendicitis.

Assessment of the normal and pathological alignment of the elbow in children using the trochleocapitellar index.

BACKGROUND: The current research is a retrospective study that involves the description of a new trochleocapitellar index (TCI), on basis of anteroposterior (AP) radiographs of normal and fractured paediatric elbows. This index may be useful in assessing the alignment of the elbow with a supracondylar fracture. METHODS: The index was evaluated to define its normal and pathological range in children between the ages of 1-13 years. A total of 212 elbows in 141 children were radiographically evaluated. 70 children without fracture elbows were evaluated by radiographs taken at the time of trauma. 35 children with unilateral fractures that healed in a normal alignment were compared to 33 patients that had a mal-union and three patients with bilateral elbow fractures. The patients were radiographically assessed at the time of fracture as well as after fracture healing as part of a routine clinical assessment. Treatment included observation, cast or internal fixation as needed. RESULTS: The current study establishes that the normal range of the TCI was 0.25-0.8. The average TCI is 0.45. The lower range correlates with a valgus alignment of the elbow while the higher range indicates a neutral alignment. The TCI in fractured elbows that have healed in a clinically normal alignment is different than the contra-lateral elbow's TCI. This might indicate a sub-clinical remaining deformity. CONCLUSIONS: In current practice, paediatric patients with elbow trauma, often undergo bilateral radiographs during emergency room visits. The TCI has high negative and positive predictive values and might be superior to direct angle measurement that is currently in use. The use of the TCI measurement is expected to reduce exposure to irradiation in elbow trauma patients as bilateral comparative films appear to be superfluous when this measurement is used.

Predelivery sonographic predictors of obstetric anal sphincter injury among nulliparous women.

OBJECTIVE: Data available at admission to delivery of nulliparous has rarely been investigated for prediction of obstetric anal sphincter injury (OASI). The aim of the present study was to study risk factors for OASI in nulliparous based on information available at admission. METHODS: A retrospective study of all nulliparous women undergoing labor, during March 2011 to January 2021 was performed. We compared women with OASI following delivery to those without by univariate and multivariable regression. RESULTS: A total of 30 262 deliveries were included and 4181 (13.4%) of those were delivered by an emergent cesarean delivery. OASI followed 453 (1.5%) deliveries. Women in the OASI group were younger 29 ± 4.4 versus 30 ± 4.8, P = 0.001. In a multivariable regression analysis, higher sonographic estimated fetal weight was positively associated with OASI occurrence (aOR, 95% CI: 1.13 [1.00-1.29]). Maternal age was inversely associated with OASI occurrence (adjusted odds ratio [aOR], 95% confidence interval [CI] 0.95 [0.92-0.97]). CONCLUSION: Sonographic fetal weight estimation is an independent risk factor for OASI occurrence that may be available at admission for delivery among nulliparous women.

Prepubertal chronic stress and ketamine administration to rats as a neurodevelopmental model of schizophrenia symptomatology.

Increased vulnerability to psychiatric disorders, such as schizophrenia, has been associated with higher levels of stress. In the early development of the central nervous system, changes in function of glutamatergic N-Methyl-D-aspartate (NMDA) receptors can possibly result in the development of psychosis, cognitive impairment and emotional dysfunction in adulthood. Thus, in this study we examined the behavioural consequences of the exposure of male rats to chronic stress (postnatal days 30-60) and ketamine administration (postnatal days 41-45); both during a sensitive developmental time window. We found that the locomotor activity of both ketamine and ketamine+chronic stress groups was significantly higher compared with that of the control rats. In contrast, the locomotor activity of the chronic stress group was significantly lower compared with all other groups. Examining anhedonia in the sucrose preference test we found a significantly decreased sucrose intake in both ketamine+chronic stress and the chronic stress groups compared with the control rats. No significant differences were observed in sucrose intake between the control and the ketamine group. The object recognition test revealed that the attention to the novel object was significantly impaired in the ketamine+chronic stress group. Similarly, the ketamine+chronic stress group showed the poorest learning ability in the eight-arm radial maze, starting on the 8th day. Finally, throughout the different pre-pulse intensities, the ketamine+chronic stress group showed impaired PPI compared with all other groups. The results indicate that the combination of prepubertal onset of chronic stress and ketamine may serve as a valid novel animal model for schizophrenia-like symptoms.

Combined 3D Endoanal Ultrasound and Transperineal Ultrasound Improves the Detection of Anal Sphincter Defects.

INTRODUCTION: Anal sphincter injury, mainly due to obstetric or iatrogenic etiology, is the most common cause of fecal incontinence (FI). Three-dimensional endoanal ultrasound (3D EAUS) is used for assessment of the integrity and the degree of anal muscle injury. However, 3D EAUS accuracy may be hampered by regional acoustic effects, such as intravaginal air. Therefore, our aim was to examine whether a combination of transperineal ultrasound (TPUS) and 3D EAUS would improve the accuracy of detection of anal sphincter injury. METHODS: We prospectively performed 3D EAUS followed by TPUS in every patient evaluated for FI in our clinic between January 2020 and January 2021. The diagnosis of anal muscle defects was assessed in each ultrasound technique by two experienced observers that were blinded to each other's assessments. Interobserver agreement for the results of the 3D EAUS and the TPUS exams was examined. A final diagnosis of anal sphincter defect was based on the results of both ultrasound methods. Discordant results were re-analyzed by the two ultrasonographers for a final consensus on the presence or absence of defects. RESULTS: A total of 108 patients underwent ultrasonographic assessment due to FI (mean age 69 ± 13). Interobserver agreement for the diagnosis of tear on EAUS and TPUS was high (83%) with Cohen's kappa of 0.62. EAUS confirmed anal muscle defects in 56 patients (52%), while TPUS confirmed them in 62 patients (57%). The final consensus agreed on the diagnosis of 63 (58%) muscular defects and 45 (42%) normal exams. The Cohen's kappa coefficient of agreement between the results of the 3D EAUS and the final consensus was 0.63. CONCLUSIONS: The combination of 3D EAUS and TPUS improved the detection of anal muscular defects. The application of both techniques for the assessment of the anal integrity should be considered in every patient going through ultrasonographic assessment for anal muscular injury.

Management of Chronic Anal Fissure with a Novel Topical Hemp-Herbal-Based Ointment: A Pilot Study.

Introduction: Anal fissure (AF) is a common anorectal disease. Although several pharmacological treatments are available, many patients still require surgical interventions. In this study, we aimed to evaluate the efficacy of an ointment based on a multifunctional blend of herbal ingredients including hemp (ProctoFiz) for chronic AF. Methods: A single-arm, questionnaire-based prospective study was conducted in a large tertiary center to evaluate the outcomes of patients suffering from chronic AF treated with topical ProctoFiz. Results: Ninety-two patients were included in the study, 54 (58.7%) were females with a median age of 39 (range 17-78). 32 patients (34.7%) suffered from recurrent AF before enrolling in the study, and 5 patients (5.4%) underwent previous surgical interventions for AF. Three patients (3.2%) were lost to follow-up, leaving 89 patients for analysis. Eighty patients (89.9%) reported significant improvement of symptoms after 1 week using ProctoFiz, and 79 patients reported continued improvement after 1 month of treatment. The mean pain Visual Analog Score (VAS) declined by 6.6 points (8.9 vs. 2.3; 95% CI: 7.20 to -5.99, p < 0.0001) following 1 week of treatment, with continuous improvement to a mean of 0.64 after 1 month. Negative impact on quality of life significantly decreased from a mean of 8.8 to 0.38 following a month of treatment (p < 0.0001), with significant reduction in the number of patients suffering from bleeding following bowel movements (64.1-2.5%; p = 0.0001). Conclusion: Hemp-based topical treatment of AF is feasible and significantly improves AF-correlated symptoms.

Laser hemorrhoidoplasty for II-IV grade hemorrhoids: should we treat them the same?

Laser Hemorrhoidoplasty (LHP) is a novel therapeutic option for hemorrhoids. In this study, we aimed to evaluate the post-operative outcomes of patients undergoing LHP surgery based on hemorrhoid grade. A retrospective analysis of a prospective database of all patients who underwent LHP surgery between September 2018 and October 2021 was performed. Patients' demographics, clinical perioperative data, and post-operative outcomes were recorded and analyzed. One hundred and sixty two patients that underwent laser hemorrhoidoplasty (LHP) were included. Median operative time was 18 min (range 8-38). Median total energy applied was 850 Joule (450-1242). Complete remission of symptoms following surgery was reported by 134 patients (82.7%), while 21 patients (13%) reported partial symptomatic relief. Nineteen patients (11.7%) presented with post-operative complications, and 11 patients (6.75%) were re-admitted following surgery. Post-operative complication rate was significantly higher in patients with grade 4 hemorrhoids compared to grades 3 or 2, due to a higher rate of post-operative bleeding (31.6% vs. 6.5% and 6.7%, respectively; p = 0.004). Furthermore, post-operative readmission rate (26.3% vs. 5.4% and 6.2%; p = 0.01) and reoperation rate were also significantly higher in grade IV hemorrhoids (21.1% vs. 2.2% and 0%; p = 0.001). Multivariate analysis found that grade IV hemorrhoids had a significantly higher risk for post-operative bleeding (OR 6.98, 95% CI 1.68-28.7; p = 0.006), 30-day readmission (OR 5.82, 95% CI 1.27-25.1; p = 0.018), and hemorrhoids recurrence (OR 11.4, 95% CI 1.18-116; p = 0.028). LHP is an effective treatment for hemorrhoids grades II-IV, but carries significant risk for bleeding and re-intervention in patients with grade IV hemorrhoids.
