Evaluation of the Preoperative Slide Test in the Prediction of Intra-Abdominal Adhesions: A Single-Center, Double-Blinded, Prospective Observational Study.

BACKGROUND: To evaluate the efficacy of the preoperative ultrasonographic sliding sign in predicting intra-abdominal adhesions. METHODS: This was a single-center, double-blinded, prospective observational study undertaken from March and September 2021 on 110 patients with a history of previous abdominal surgery. All patients who were scheduled for laparoscopy underwent slide test in 5 zones of abdomen: right lower quadrant, left lower quadrant, previous operation site, vesicouterine pouch, and rectovaginal pouch. Adhesions were assessed by the same gynecologic surgeon using ultrasonography before the surgery and by gynecological surgeons during surgery, and by a third gynecologic surgeon to compare the preoperative slide test findings and laparoscopic findings after the surgery. RESULTS: Seventy-three (66.4%) patients underwent laparoscopic surgery, and 37 (33.6%) patients underwent laparotomy. The mean age of patients was 46.9 ± 1.0 years. Sensitivity, specificity, and positive and negative predictive values of preoperative ultrasonography in predicting adhesions were 89.5%, 91.7%, 97.5%, and 71.0%, respectively. The accuracy of the slide test was calculated as 90.0%. It was found that as the total number of cesarean sections increased the estimates of vesicouterine adhesions and actual adhesions increased (P = .008). Also, the prediction of intra-abdominal adhesions and actual adhesions significantly increased as the total number of surgical operations increased (P = .002). CONCLUSIONS: Intra-abdominal adhesions can be detected with the slide test, which is a non-invasive and well-tolerated procedure. Slide test can guide the physician before the elective operation in patients with previous abdominal surgery and may assist in counseling patients.

Molecular communication between Apelin-13, Apelin-36, Elabela, and nitric oxide in gestational diabetes mellitus.

OBJECTIVE: Gestational diabetes mellitus (GDM) is a type of diabetes that affects from 3.8% to 6.9% of pregnancies worldwide, causing significant mortality and unfavorable obstetric outcomes, such as delivery trauma and macrosomia risk. The fundamental processes of this metabolic disorder that first appeared during pregnancy are still unknown. Tissue hormones, particularly adipokines, have aided in understanding the pathophysiology of numerous disorders in recent years. This study aims to determine if Apelin-13 (APLN-13), Apelin-36 (APLN-36), Elabela (ELA), and nitric oxide (NO) molecules have all a part in the pathophysiology of GDM. PATIENTS AND METHODS: The study included 30 pregnant control women and 30 pregnant women who had been diagnosed with GDM in the second trimester and whose body mass index and age were compatible with each other. Blood samples were collected from 60 participants during the second trimester (30 control pregnant women and 30 GDM pregnant women) and postpartum (17 controls vs. 14 GDM). In these blood samples, the amounts of APLN-13, APLN-36, ELA, and NO were studied using the ELISA method. In addition, the participants' glucose, lipid profiles, and other parameters were obtained from the hospital record files. At postpartum, 29 pregnant women (13 control and 16 pregnant women with GDM) dropped out of the study without explanation. RESULTS: In the second trimester and postpartum plasma of mothers with GDM, APLN-13, APLN-36, NO, and ELA molecules were found to be significantly higher (< 0.05), compared to those of the control mothers, while APLN-13, APLN-36, NO values were significantly lower (0.05). While APLN-13, APLN-36, NO amounts in mothers with GDM were positively correlated with glucose amounts, they were negatively correlated with ELA amounts. Similarly, the triglyceride amounts in mothers with GDM were positively correlated with APLN-13, APLN-36 and NO, while they were negatively correlated with the ELA amounts. Due to gestational diabetes, APLN-13, APLN-36, NO, glucose, and triglyceride increased, and ELA decreased. CONCLUSIONS: It is predicted that the glucose increase in GDM is because Apelins reduce glucose transport to erythrocytes by inhibiting the sodium-dependent glucose transporter (SGLT) and that the increase in triglyceride and NO may be associated with high glucose levels in GDM. As a result, we believe that the above-mentioned chemicals may cause GDM Pathology by triggering one another.

Leptin/Melanocortin pathway hormones in obese patients after laparoscopic sleeve gastrectomy.

OBJECTIVE: The melanocortin system is an important neural system underlying the control of body weight and food intake. This system has recently received great attention as a potential target for obesity treatment. Therefore, the objective of this study was to find out the leptin-melanocortin pathway before and after Laparoscopic Sleeve Gastrectomy (LSG) in obese patients. PATIENTS AND METHODS: The study was carried out with a total of 144 individuals in 3 groups [control, obese group before LSG and obese group after LSG (who underwent LSG one year ago)]. The amount of leptin (LEP), leptin receptor (LEPR), tropomyosin receptor kinase receptor B (TrkB), brain-derived neurotrophic factor (BDNF), pro-opiomelanocortin (POMC) and melanocortin-4 receptors (MC4R) molecules were measured by using Enzyme-Linked Immunosorbent Assays. RESULTS: A statistically significant difference was found between the groups in terms of body mass index (BMI) values (p = 0.001). There was also statistically significant difference present between obese before LSG group and obese after LSG group regarding the levels of LEP, TrkB, BDNF and proteins (p < 0.05). A decline was determined in the LEP and BDNF levels one year follow-up after LSG. CONCLUSIONS: The evidence suggests that the leptin melanocortin pathway strictly regulates food intake and BMI before and after LSG surgery. This pathway should be kept under control for effectively reducing food intake and body weight in the treatment of obesity.

Can renalase be a novel candidate biomarker for distinguishing renal tumors?

Renalase (RNLS) is synthesized mainly in renal tissues. The function of RNLS in cancerous renal tissues has not been investigated. We investigated the synthesis of RNLS in chromophobe renal cell carcinoma, papillary renal cell carcinoma and clear cell renal cell carcinoma with Fuhrman grades (FG): FG1, nucleoli are absent or inconspicuous and basophilic; FG2, nucleoli are conspicuous and eosinophilic and visible but not prominent; FG3, nucleoli are conspicuous and eosinophilic; FG4, extreme nuclear pleomorphism, multinucleate giant cells, and/or rhabdoid and/or sarcomatoid differentiation. We used 90 tissue samples including 15 healthy controls, 15 chromophobe renal cell carcinoma tissues and 10 papillary renal cell carcinoma renal tissues: 12 FG1, 14 FG 2, 14 FG 3 and 10 FG4. RNLS in the tissue samples was measured using enzyme linked immunosorbent assay and immunostaining of RNLS in these tissues. RNLS was significantly greater in the chromophobe renal cell carcinoma and papillary renal cell carcinoma tissues than the control. The least amount of RNLS was found in the renal tissues of clear cell renal cell carcinoma FG1; the amount of RNLS increased as the FG grades increased. Because RNLS increased significantly in renal tissues due to cancer, except for clear cell renal cell carcinoma FG1, RNLS may be useful biomarker for distinguishing grades of renal cancer. Because RNLS increases cell survival, anti-RNLS preparations may be useful for treating cancer in the future.

Factors Affecting the Histopathological Outcomes of Atypical Glandular Cells on Pap Test.

BACKGROUND: Glandular cell abnormalities may indicate the presence of pre-malignant or malignant lesions. AIM: This study aimed to investigate the relationship between atypical glandular cells (AGC) and patients' demographics, histopathological outcomes, Human Papillomavirus (HPV) test results. MATERIAL AND METHODS: Between January 2015 and December 2019, women with AGC on Pap tests were retrieved from the hospital electronic database. The patients with AGC on cervicovaginal smears who underwent further pathological, laboratory, and imaging diagnostic testing and who were followed up at least 1-year were included in the study, while those who had a history of cervical dysplasia or cancer, lost during follow-up, or had missing data were excluded. RESULTS: Of 85,692 Pap smears, 114 (0.13%) were diagnosed with AGC, of those 88 cases were eligible for final analysis. Gynecological malignancies were detected in 13 (14.8%) patients; including 6 (6.8%) endometrioid endometrial cancers, 3 (3.4%) non-endometrioid endometrial cancers, 2 (2.3%) cervical adenocarcinomas, 1 (1.1%) cervical squamous cell carcinoma, and 1 (1.1%) high-grade tubal serous cancer. Multivariate analysis revealed that presence of concomitant abnormal squamous lesion (P = 0.002), being 50 years and older (P = 0.028), HPV positivity (P < 0.001), and menopause (P = 0.023) were risk factors for significant pathology. CONCLUSION: The diagnosis of AGC may be related to the preneoplastic/neoplastic processes. A further comprehensive histopathological examination is required in women with AGC, aged 50 years and older, postmenopausal, HPV-positivity and concomitant squamous cell abnormality Clinicians should consider ovarian pathologies when there is no pathological finding on endometrial or cervical histopathological examination.

How Important is the Timing of Radioiodine Ablation in Differentiated Thyroidal Carcinomas: A Referral Centre Experience. / Cómo es de importante el momento de la ablación con radioyodo en los carcinomas diferenciados de tiroides: la experiencia de un centro de referencia.

INTRODUCTION: It's difficult to make a scientific, evidence-based approach about the timing of radioiodine remnant ablation (RRA) in patients with differentiated thyroid carcinomas (DTCs). Primary aim of the study was to reveal whether timing of RRA relates to achievement of non- structurally incomplete response (non-SIR) in low/intermediate and high-risk patients. Another aim was to reveal the correlation of timing with non-SIR status in reproductive-age women. MATERIALS AND METHODS: Records of 279 low, intermediate, and high-risk patients were analysed, retrospectively. Number of days between surgery and RRA is referred to as timing. Low/intermediate-risk patients, high-risk patients, and low/intermediate-risk reproductive-age women were divided into non-SIR and SIR groups, according to 2015 American Thyroid Association guidelines for therapy response. The relationship between timing and therapy response was analysed statistically. RESULTS: We could not find any significant relationship in patients with low/intermediate risk between timing and non-SIR, including women between 18-49 years of age (p >0.1). For high-risk patients, we found a statistically significant relationship between timing and non-SIR response. According to ROC analysis, RRA ≤58 days was found as a cut-off value. The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were calculated as 83.3%, 70.0%, 2.78, and 0.24, respectively. CONCLUSION: RRA must be initiated within 58 days after surgery in patients with high-risk DTCs. Under this approach, risk of SIR and associated mortality risk may be reduced. RRA timing for women in reproductive ages with low/intermediate risk groups may be planned according to their pregnancy/breastfeeding intent. For other low/intermediate risk groups, they can safely proceed according to the capacity of the medical facility and related logistical considerations.

Immunostaining characteristics of irisin in benign and malignant renal cancers.

We investigated the expression of irisin in renal cancers using immunocytochemistry. Irisin has been reported to exhibit anticancer properties. The study groups consisted of 22 cases each of control renal tissue, oncocytoma, chromophobe renal cell carcinoma (RCC), clear cell RCC (Fuhrman nuclear grades 1, 2, 3 and 4) and papillary RCC. We evaluated 10 slides for each of 176 cases. Slides were immunostained for irisin and histoscores were calculated for the prevalence and strength of immunostaining. Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC exhibited no irisin immunoreactivity. Irisin immunoreactivity was observed in some Fuhrman nuclear grade 4 RCCs. We found a significant decrease in irisin staining in chromophobe RCC compared to the control. Immunoreactivity in the oncocytoma tissue was comparable to the control group. Irisin immunoreactivity in chromophobe RCC decreased and no immunoreactivity was observed in Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC. Immunistochemical screening of irisin in renal oncocytomas and renal cancers may be useful for differential diagnosis.

A promising biomarker to distinguish benign and malignant renal tumors: ELABELA.

AIM: The aim of this study was to investigate ELABELA (ELA) expression in benign and malignant renal tissues and expression differences in different nuclear grades of clear cell carcinomas. MATERIALS AND METHODS: Patients that underwent surgery due to renal masses between the years of 2007 and 2017 were used. Control renal tissues (n = 23), papillary RCC (n = 23), clear cell RCC (CcRCC) [Fuhrman Grade1 (n = 23), Fuhrman Grade2 (n = 23), Fuhrman Grade3 (n = 23), Fuhrman Grade4 (n = 23)], and chromophobe RCC (n = 23) were included to the study. The Independent samples t-test was used for 2-point intergroup assessments and the one-way analysis of variance and posthoctukey test was used for the others. Values of P < 0.05 were considered statistically significant. RESULTS: ELA immunoreactivity was observed in proximal and distal tubules in the kidney, but not in glomeruli in control tissues. When compared with control kidney tissue, a statistically significant increase was observed in ELA immunoreactivity in renal oncocytoma. In the chromophobe RCC, ELA immunoreactivity was significantly lower than control kidney tissue, whereas papillary RCC did not show ELA immunoreactivity. However, compared with control kidney tissue, ELA immunoreactivity was not observed in Fuhrman Grade 1 and Grade 2 CcRCC. Also, there was a significant decrease at Fuhrman Grade 3 and Grade 4 CcRCC compared with control kidney tissues. In the statistical analysis of ELA immunoreactivity among the Fuhrman nuclear grades of CcRCCs, The ELA immunoreactivity was higher at Grade 4 CcRCC than Grade 1, Grade 2, and Grade 3. CONCLUSION: ELA is a usefull molecule to differentiate benign and malign renal tumors. But further broad and comprehensive studies are needed to investigate cellular and molecular mechanisms of ELAs on malign transformation.

The importance in diagnosing patients with conflicting observational data for post surgery radioiodinated ablation of thyroid remnants.

OBJECTIVE: There is a special group of patients, according to 2015 American Thyroid Association guidelines. This group is defined as "the patients with conflicting observational data for post-surgery radioiodine ablation (COD for PSRIA)". For this special group of patients RIA is applied after a thorough reassessment of histopathological, clinical and biochemical features, including thyroglobulin (Tg). However, there is no consensus on what is the suitable cut-off value for the radioiodine ablation (RIA) decision or for therapy prediction. Moreover, is also unclear which Tg parameters should be used for these purposes. If we can determine useful and practical cut-off values for excellent response (ER) and non-structural incomplete response (non-SIR) response categories, this will facilitate our therapy response prediction before RIA and may allow us to categorize the group of "COD for PSRIA" based on a higher risk of recurrence/relapse or disease specific mortality rates according to serum thyroglobulin (Tg). This categorization may also enable us to plan the follow-up frequency of patients more scientifically. Consequently, it may provide the more efficient use of medical facility and healthcare system resources. SUBJECTS AND METHODS: Two hundred forty-nine patients (out of 577 examined) with "COD for PSRIA" were included in this study. Firstly, patients with indeterminate, biochemical incomplete and structural incomplete responses were considered as the non-ER group and compared to the ER group. Secondly, patients with excellent, indeterminate, and biochemically incomplete responses were considered as the non-SIR group and compared to the SIR group. The data were evaluated by MedCalc Statistical Software version 18.9. RESULTS: The cut-off value for ER patients was calculated as ≤6.57ng/mL. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 67.9%, 75.4%, 55.6% and 83.8%, respectively. The cut-off value for non-SIR patients was calculated as ≤12.7ng/mL. Sensitivity, specificity, PPV and NPV were 78.5%, 91.7%, 35.5% and 98.6%, respectively. CONCLUSION: If a patient has ≤6.57ng/mL pre-ablative Tg, follow-up intervals of patients with "COD for PSRIA" may be extended due to lower recurrence/relapse rates. However, if a patient has >12.7ng/mL pre-ablative Tg, these patients should be followed-up more frequently in order to determine SIR earlier. This approach may enable more efficient use of medical facility and healthcare system resources and a more scientific planning of their follow-up treatment. This approach seems to have the potential to contribute significantly to cost-effectiveness.

The effect of different nasal irrigation solutions following septoplasty and concha radiofrequency: a prospective randomized study / Efeito de diferentes soluções para irrigação nasal após septoplastia e radiofrequência das conchas nasais: estudo prospectivo e randomizado

Abstract Introduction Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing. Objective The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency. Methods The present study was a prospective, randomized, controlled simple blind study of 120 patients who underwent septoplasty and bilateral concha radiofrequency. Patients were divided into four groups according to the nasal irrigation solution used: tap water, buffered isotonic saline, saline with xylitol, and hypertonic sea water. Patients were examined on the 7th and 15th postoperative days. A saccharine test was applied to determine mucociliary activity preoperatively and on the 7th and 15th postoperative days. Patients were asked about drying and obstruction using a 10 cm visual analog scale. In addition, patients were examined to determine the crusting score. Results There was no significant difference found in the preoperative and 7th and 15th postoperative days' mucociliary clearance times among the four groups. The crusting score was found to be significantly lower in the hypertonic sea water group (p < 0.001). Drying and obstruction on the 7th and 15th postoperative days were found to be significantly more comfortable in the hypertonic sea water group (p < 0.001). Conclusion Hypertonic sea water is the recommended irrigation solution, as it is associated with less crusting, drying, and obstruction in the nose for the postoperative period following septoplasty and concha radiofrequency.

Resumo Introdução Soluções para irrigação nasal são amplamente usadas após cirurgias endonasais. Essas soluções removem os resíduos e crostas, reduzem a probabilidade de formação de sinéquias e aceleram a cicatrização da mucosa. Objetivo O objetivo do presente estudo foi comparar os efeitos das soluçoes para irrigaçao nasal com diferentes conteudos apos septoplastia e turbinoplastia com radiofrequencia. Método O presente estudo foi um estudo cego simples, randomizado, controlado e prospectivo de 120 pacientes submetidos a septoplastia e turbinoplastia bilateral com radiofrequencia. Os pacientes foram divididos em quatro grupos de acordo com a soluçao nasal utilizada: agua da torneira, soluçao salina isotonica tamponada, soluçao salina com xilitol e agua do mar hipertonica. Os pacientes foram examinados no 7° e 15° dias do pos-operatorio. O teste de sacarina foi utilizado para determinar a atividade mucociliar pre-operatoria e no 7° e 15° dias do pos-operatorio. Os pacientes foram questionados sobre a sensaçao de secura e obstruçao nasais utilizando uma escala visual analógica de 10 cm. Alem disso, os pacientes foram examinados para determinar o escore em relaçao a crostas. Resultados Não houve diferença significativa entre o pré-operatório e o sétimo e 15° dias do pós-operatório dos tempos de clearance mucociliar entre os quatro grupos. Verificou-se que o escore em relação a crostas foi significativamente menor no grupo que usou água do mar hipertônica (p < 0,001). As sensações de secura e obstrução nasais no sétimo e 15° dias do pós-operatório mostraram-se significativamente mais confortáveis no grupo água do mar hipertônica (p < 0,001). Conclusão A água de mar hipertônica é a solução de irrigação recomendada, pois está associada a menor incidência de crostas, secura e obstrução nasais no pós-operatório de cirurgia de septoplastia e das conchas nasais com radiofrequência.

Influence of CPAP treatment on airway and systemic inflammation in OSAS patients.

AIM: Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent respiratory disorders in the upper airways during sleep. Although continuous positive airway pressure (CPAP) has been accepted to be the most effective treatment for OSAS, its role on inflammation remains debatable. In this study, our aim was to examine the influence of 3 months of CPAP treatment on tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), 8-isoprostane, and peroxynitrite levels in exhaled breathing condensates (EBC) and serum. METHODS: Thirty-five patients who were newly diagnosed as moderate or severe OSAS with full night polysomnography and used CPAP therapy regularly for 3 months were included in the study. Polysomnography, spirometric tests, fasting blood samples, and EBC were ascertained on entry into the study and after 3 months of treatment. All patients were assessed monthly for treatment adherence and side effects. RESULTS: We found that all polysomnographic parameters were normalized after CPAP therapy in the control polysomnogram. Also, all markers in EBC and nitrotyrosine and 8-isoprostane levels in serum were decreased significantly with CPAP treatment. Sedimentation rate, C-reactive protein, IL-6, and TNF-α remained unchanged in serum after treatment. We found that baseline nitrotyrosine levels were significantly correlated with apnea-hypopnea index, oxygen desaturation index, and percent time in SpO2 < 90 % (p < 0.01). CONCLUSIONS: CPAP therapy has primarily a relevant impact on airways, and nitrotyrosine levels correlated well with severity of OSAS. This treatment decreases both inflammation and oxidative stress levels in airways in OSAS patients. Also, this treatment helps to decrease systemic oxidative stress levels in serum.

Comparing anterior palatoplasty and modified uvulopalatopharyngoplasty for primary snoring patients: preliminary results.

OBJECTIVES: To evaluate and compare the long-term efficacy of modified uvulopalatopharyngoplasty (mUP3) and anterior palatoplasty (AP) techniques for treating snoring in a prospective clinical trial. METHODOLOGY: Patients with total apnea-hypopnea index values < 5/per hour sleep were included in the study. Patients completed the Epworth sleepiness scale (ESS) and snoring visual analogue scale (VAS) before and 24 months after surgery, and a VAS for pain after the operation. RESULTS: Twenty-four patients were in the mUP3 group with a mean age of 42.1 +/- 11.8 years, and 26 in AP group with a mean age of 43.2 +/- 10.4 years. Snoring VAS values were significantly decreased after surgery in both groups (p < 0.025), but changes between operative groups were not statistically significant (p > 0.05). Patients' ESS scores in both groups significantly decreased (p < 0.025), but ESS score changes between groups were not significantly different (p > 0.05). Two years postoperatively, patient satisfaction was 85% in the AP group, and 70% in the mUP3 group. Pain VAS values were significantly lower in the AP group than in the mUP3 group (p < 0.001). Eight patients (33.3%) in the mUP3 group and one (7.7%) in the AP group reported nasal regurgitation of liquids upon swallowing during the first week postoperatively. Two years after the operation, 10 patients (41.6%) in the mUP3 group and 9 (34.6%) in AP group still had a lump sensation in the throat. CONCLUSIONS: We compared the efficacy of the mUP3 and AP techniques to treat patients with primary snoring and found less morbidity and more patient satisfaction in the AP group.

Tongue abscess with actinomycosis.

Actinomycosis of the tongue is uncommon, but without proper treatment, it causes extensive tissue destruction. A mass that may mimic both benign and malignant neoplasms can be seen at clinical presentation and may mislead the diagnosis. Early diagnosis is critical but usually difficult with cultures or imaging. We report a patient who presented with a tumor-like deeply localized primary actinomycosis of the tongue with its magnetic resonance imaging findings.

Comparison of adenoidectomy methods: examining with digital palpation vs. visualizing the placement of the curette.

OBJECTIVE: To evaluate the effectiveness of adenoidectomy by defining the remnant volume and localization in nasopharynx, following being satisfied with completeness of removal of the adenoid tissue with digital palpation. METHODS: A prospective study conducted on 99 patients undergoing adenoidectomy+/-tonsillectomy. The main mass of the patient's adenoid tissue was removed with a sharp adenoid curette without visualization and the surgeon was allowed to palpate the adenoid bed and repeat the curettage until satisfied with completeness of removal. Then nasopharynx was visualized with a laryngeal mirror for defining the anatomical localization of the residual adenoid tissue and curettage completed under indirect mirror visualization. The volumes of the adenoid tissue excised at both stages were measured. RESULTS: By blunt curettage and digital palpation, only 20.2% of the patients (20) had no residual adenoid tissue. In patients who had residual adenoid tissue, the proportion of the median percentage of residual adenoid tissue to total adenoid tissue was 19.98% (range 3.22-50%). The anatomical localization of the residual adenoid tissue were, along the torus tubarius on either side of the nasopharynx in 9 (11.4%), on the pharyngeal roof near choanal openings in 64 (81%), along the torus tubarius on either side of the nasopharynx+on the pharyngeal roof near choanal openings in 5 (6.3%), and on the pharyngeal roof near choanal openings+on the posterior wall of nasopharynx in 1 (1.3%) patients. There was no difference found among surgeons in the percentage and the location of the residue left (p>0.05). CONCLUSION: Digital palpation is not a dependable technique and visualization of the nasopharynx is crucial for a complete adenoidectomy.

Effects of a topical hemostatic agent on an epistaxis model in rabbits.

BACKGROUND: Ankaferd BloodStopper (ABS) is a standardized herbal compound consisting of 5 different plant extracts. ABS, as a topical medicinal product, has been approved by the Turkish Ministry of Health for the management of dermal, external postsurgical and postdental surgery bleedings. OBJECTIVE: The aim of this study was to assess the hemostatic effect of ABS in an experimental epistaxis model. METHODS: Adult female New Zealand rabbits were used in this study. Standardized full-thickness mucosal wounds were created to provide bleeding on the right and left side of the nasal septum of rabbits with a 3-mm surgical punch. To stop bleeding, the wounds were treated with topical ABS on one side and with topical isotonic saline solution as a control on the other side of the nasal septum. Investigators were blinded to treatment. The duration of bleeding was measured in order to compare the hemo-static effect with ABS or topical isotonic saline solution. The wounds were observed for the duration of bleeding in order to compare the hemostatic effect of ABS with isotonic saline solution and acute adverse effects (AEs) for 30 minutes by a researcher blinded to treatment groups. RESULTS: Six rabbits (mean weight, 2.6 kg [range, 2.3-3.1 kg]) were used in this study. Mean (SD) bleeding time in the wounds administered ABS (98 [17] sec) was significantly less than that of the controls (266 [36] sec; P = 0.004). No AEs were observed up to 30 minutes after study initiation. CONCLUSION: This study suggests that ABS may be more effective in reducing time to hemostasis when compared with isotonic saline solution in this epistaxis model in rabbits.
