Prognostic implications of response to neoadjuvant chemotherapy in breast cancer subtypes.

The current study was designed to assess the response to treatment, as well as clinical and survival outcomes, across different breast cancer subtypes in patients who underwent neoadjuvant chemotherapy (NAC). From 2014 to 2019, a total of 139 patients who were histologically confirmed to have breast cancer, underwent NAC, and subsequently received breast and axillary surgery, were retrospectively included in this study. The rates of pathological complete response (pCR) to NAC were significantly higher for HER2-positive and triple-negative subtypes than for luminal A and HER2-negative subtypes (p = 0.013). Multivariate analysis for disease-free survival (DFS) revealed that tumour grade and the presence of pCR were independent prognostic factors. The presence or absence of a pCR with NAC was an independent prognostic indicator in the multivariate analysis for overall survival (OS). Lastly, achieving a pCR was independently predicted by 18F-FDG PET/CT findings, the HER2-positive subtype, and the triple-negative subtype. Despite the inherent methodological limitations, our findings underscore the significance of identifying predictive markers to tailor NAC plans, with the aim of improving survival outcomes.

Relationship between the change in tumour-infiltrating lymphocyte level and residual tumour after neoadjuvant chemotherapy in patients with locally advanced breast cancer.

To evaluate the tumour-infiltrating lymphocyte (TIL) rates in breast tissue before and after neoadjuvant chemotherapy (NAC) and their impact on survival, eighty-four patients with locally advanced breast cancer (LABC) were assessed. Pre- and post-NAC TIL levels were determined using biopsy and surgical specimens, respectively. The median TIL rate was significantly different before (17.5%) and after (5%) NAC. Pre- and postoperative Ki-67 index, molecular subtype, pre- and post-NAC TIL concentration, and preoperative residual-cancer-burden TIL were significantly associated with pathological complete response (pCR). Specifically, higher pre-NAC TIL levels were associated with higher pCR rates. Postoperative Ki-67 index and pCR, and postoperative Ki-67 index were significant predictors of disease-free (DFS) and overall survival, respectively. The independent prognostic factors for DFS were postoperative Ki-67 score (hazard ratio [HR]: 6.16; p = 0.012), post-NAC TIL score (HR: 0.42; P = 0.041), and pCR (HR: 0.10; P = 0.038). Our study confirms that higher pre-NAC and lower postoperative TIL levels may be surrogate factors for longer DFS, and postoperative TIL rate may predict post-NAC pCR in patients with LABC.

Efficacy of proprioceptive neuromuscular facilitation in improving shoulder biomechanical parameters, functionality, and pain after axillary lymph node dissection for breast cancer: A randomized controlled study.

PURPOSE: Axillary lymph node dissection and radiotherapy have been associated with pain, physical symptoms, and decreased functional abilities in the upper extremity. This study aimed to evaluate the potential effects of the proprioceptive neuromuscular facilitation (PNF) technique on muscle strength, pain and functionality in this patient group in comparison with progressive resistance training (PRT). METHODS: The study was conducted with a randomized clinical trial design. Sixty-six women were included in the study and randomly divided into three groups: the PNF group (n = 22), the PRT group (n = 22), and the control group (n = 22). The participants were evaluated at the baseline and after eight weeks of treatment. Outcome measures were determined as pain (the Visual Analog Scale), upper extremity strength (isokinetic dynamometer), functionality (the Disabilities of the Arm, Shoulder and Hand questionnaire), and perception of change (the Global Rating of Change Scale). TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05288036. RESULTS: The results showed statistically significant changes in both treatment groups in terms of shoulder flexors/extensors, abductor/adductors, internal/external rotators strength/power/endurance measurement, pain, and functionality (p < 0.05). Concerning functionality and perception of change, the PNF group had a statistically significantly higher improvement compared to the remaining two groups (p < 0.05). CONCLUSION: PNF is an effective technique in increasing upper extremity muscle strength, reducing pain during rest and activity, and improving functionality in patients receiving breast cancer treatment.

Pretreatment platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio as a predictor of pathological complete response to neoadjuvant chemotherapy in patients with breast cancer: single center experience from Turkey.

The aim of this study was to investigate the predictive value of PLR and NLR as an indicator of pathological complete response (pCR) in patients with breast cancer after NACT. One hundred thirty-nine patients with early or LABC and candidates to NACT were retrospectively analyzed. The prognostic significance of PLR and NLR was analyzed. In addition, predictive indicators of pCR to NACT were also evaluated. pCR was obtained in 48.9% of patients. Significant difference was detected between pCR and PLR, tumor grade, clinical lymph node status and molecular subgroup. The higher rate of pCR was significantly achieved for patients with PLR low ( < 181.7) compared with those with PLR high (>181.7) (68.6% vs. 33.4%; P < 0.001). PLR, tumor grade and pCR to NACT for disease-free survival (DFS), and PLR, NLR, tumor grade and pCR to NACT for overall survival were detected to be prognostic factors by univariate analysis. On the other hand, a logistic regression analysis indicated that PLR and NLR were found to be an independent factors for predicting pCR to NACT ( P < 0.001; OR, 0.07; 95% CI, 0.02-0.25 and P = 0.016; OR, 4.66; 95% CI, 1.33-16.2, respectively), as were molecular subtypes ( P = 0.001; OR, 0.23; 95% CI, 0.09-0.56). Our results showed that PLR low and NLR low before NACT are readily feasible and simple and also inexpensive biomarkers predicting pCR to NACT for patients with LABC.

YouTube English videos as a source of information on arm and shoulder exercise after breast cancer surgery.

PURPOSE: To examine the reliability, quality and content of YouTube videos on exercises that can be performed after breast cancer (BC) surgery. METHODS: Videos selected from YouTube using the search terms 'shoulder exercise and BC surgery', 'arm exercise and BC surgery' and 'physiotherapy/physical therapy and BC surgery' were categorised as useful or misleading by a surgeon and a physiotherapist. The videos were analysed using the 5-point DISCERN scale for reliability, the Global Quality Scale for quality and a 10-item scale for comprehensiveness. RESULTS: Of the 180 videos initially analysed, 82 were included in the study, and 42 (51.2%) were classified as having misleading information and 40(48.8%) as having useful information. The reliability, quality and content scores of the videos containing useful information were higher (p < 0.001). Most of the videos in the useful information group (80%) were uploaded by universities/professional organisations/physicians/physiotherapists, while the majority of those in the misleading information group (47.6%) were uploaded by websites providing independent healthcare information. CONCLUSION: YouTube can be an important instrument to protect patients from musculoskeletal system complications after BC treatment and improve existing complications. Universities, physicians and physiotherapists should be encouraged to prepare more videos containing full and accurate information on this subject.

Risk Factors for Idiopathic Granulomatous Mastitis Recurrence after Patient-Tailored Treatment: Do We Need an Escalating Treatment Algorithm?

Objective: Idiopathic granulomatous mastitis (IGM) is a rare, relapsing, benign inflammatory breast disease. Due to the conflicting etiology and differential diagnosis, the effect of varied treatment regimens on high recurrence is controversial. Therefore, we aimed to report our clinical experience in determining risk factors for recurrence after patient-tailored treatment. Methods: This study evaluated 122 patients diagnosed with IGM according to sociodemographic characteristics, reproductive history, clinical presentation, time of diagnosis and radiological examinations, treatment management, and outcomes. The patients were classified into three groups based on curative treatment settings: medical therapy alone, surgery alone, and combined therapy. Results: The rates of patients receiving medical therapy alone, surgical therapy alone, and combined therapy were 23, 15.6, and 62.4%, respectively. Low vitamin B12 levels, accompanying rheumatological disease, complaints-fistulae, number of complaints ≥3, presence of erythema nodosum, multicentricity, and treatment modality had a significant effect on disease recurrence (p < 0.05). The effect on IGM recurrence was 2.8 times greater for the patients with lower vitamin B12 levels, 4.5 times greater for those with rheumatological disease, 3.3 times greater for those with fistulae, 2.4 times greater for those presenting with ≥3 complaints, 2 times greater for the presence of multicentricity, 2.3 times greater for the presence of erythema nodosum, and 4.5 times greater for the patients receiving medical therapy alone. Conclusion: Describing a low-risk patient profile can be an alternative while choosing monotherapy methods. For IGM patients at high risk of recurrence, an escalating treatment system may be effective in preventing relapses.

Monocyte-to-High-Density Lipoprotein Cholesterol Ratio: a Candidate Parameter for a Risk Assessment Model in COVID-19.

BACKGROUND: COVID-19 has become a pandemic and threatened human public health across the world. Determining effective predictive biomarkers that can classify patients according to risk levels is critical to identify cases that can potentially progress to severe complications and death with the rapid progression of the disease. Therefore, we aimed to investigate the utility of the monocyte-to-high-density lipoprotein cholesterol ratio (MHR), a recently emerging inflammatory marker, as a clinically useful inflammation-based marker in determining patients at higher risk of decreased overall survival in patients with COVID-19. METHODS: The demographics, laboratory data, and MHR of 127 patients with laboratory confirmed COVID-19 were evaluated in terms of clinical outcomes. The patients discharged from the hospital constituted the survivor group, while those that died were evaluated as the non-survivor group. RESULTS: The MHR values were found to be significantly higher in the non-survivor group compared to the survivors (p < 0.05). The high-density lipoprotein cholesterol (HDL-C) values were significantly lower in the non-survivor group (p < 0.05), while there was no statistically significant difference in the monocyte values (p > 0.05). Spearman's analyses revealed no correlation between the MHR values and white blood cell, neutrophil, ferritin, D-dimer, and C-reactive protein (CRP) in the non-survivor group (p > 0.05). According to the binary logistic regression analysis model, the neutrophil, ferritin, D-dimer, CRP, and MHR values the most significant factors in predicting survival (p = 0.021, p = 0.004, p = 0.000, p = 0.001, and p = 0.016, respectively), and an increase in the neutrophil, ferritin, D-dimer, CRP and MHR values decreased the survival rate by 1.1, 1.5, 1.8, 1.6, and 1.7 times, respectively. CONCLUSIONS: MHR can help predict the severity of the COVID-19 disease and patient outcomes. Therefore, this parameter can serve as a clinically useful and potentially predictive inflammation-based marker for identifying patients with COVID-19 who are at higher risk of decreased overall survival. Considering the serious consequences of the current and possible future pandemics, the establishment of a risk assessment model, including MHR in COVID-19 and similar infections is of vital importance in reducing morbidity and mortality by identifying potential risk factors that can predict the course of the disease.

Role of peripheral inflammatory biomarkers, transforming growth factor-beta and interleukin 6 in predicting peritoneal adhesions following repeat cesarean delivery.

BACKGROUND: Repeat cesarean deliveries (CDs) pose a risk in the development of intra-abdominal adhesions. AIM: We aimed to examine the incidence and severity of adhesions in repeat CDs using a specific scoring system and assess the predictive power of the pre-operative value of transforming growth factor (TGF)-ß and interleukin (IL)-6 with selected peripheral inflammatory biomarkers (PIBs) in the prediction of adhesion formation. METHODS: This prospective study enrolled 91 pregnant women at term, who had previously undergone at least one or more scheduled CDs. PIBs, namely C-reactive protein, white blood cell count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index, TGF-ß, and IL-6 were studied according to the presence and location of adhesions. RESULTS: There was a significant difference only in the variables of the number of CDs, post-operative adhesion index (PAI) score, IL-6, and TGF-ß on the presence of adhesion (p < 0.05). The linear regression model revealed that the effect of the number of CDs, PAI score, and IL-6 values on TGF-ß was significant (p < 0.05). The effect of the PAI score on TGF-ß was higher than that of IL-6. As a reciprocal relationship, the effect of the TGF-ß value on the PAI score was also higher than that of IL-6. CONCLUSION: In patients with a history of repeat CDs, the preoperative determination of TGF-ß seems to be an important independent predictor of POA. The adverse events due to post-operative adhesion caused by repeat CDs can be overcome by detecting high-risk patients with a comprehensive assessment and individualized intervention integrated into overall patient management.

Sleep disturbances and non-cyclical breast pain: where to break the vicious cycle?

PURPOSE: This study aimed to assess the sleep quality of patients with the complaint of non-cyclical breast pain (NCBP), compare them to a healthy control group, and analyze the interrelationship of sleep quality with pain, anxiety, depression, and quality of life. METHODS: This cross-sectional study was conducted in consecutive women presenting to the general surgery clinic between May 2020 and December 2020. Patients diagnosed with NCBP formed one group for study and 44 receiving routine well-woman care formed the control group. Evaluations were undertaken using the Nottingham Health Profile (NHP), short-form McGill Pain Questionnaire (SF-MPQ), Hospital Anxiety and Depression Scale (HADS), and Pittsburgh Sleep Quality Index (PSQI). RESULTS: Of 160 consecutive patients, 116 were diagnosed with NCBP and 44 controls. Poor sleep quality (PSQI > 5) was present in 59% (n = 69) of the women with NCBP and 38% (n = 17) of the controls (p = 0.018). According to PSQI global score, overall sleep quality was significantly lower in the NCBP group compared to the control group (p < 0.007). Sleep latency, sleep duration, and daytime dysfunction were the major components determining the PSQI global score (p = 0.004, p = 0.004, and p < 0.001, respectively). The correlation matrix revealed a statistically significant correlation between the HAD-A, HAD-D, and SF-MSQ and NHP subgroups and PSQI global score in the NCBP group (p < 0.001) whereas this significant correlation was detected with only the NHP subgroups among the controls. CONCLUSIONS: A considerable proportion of NCBP patients, regardless of sensory or affective characteristics and trajectory of pain, experience significant sleep disturbances. Further studies should be conducted to evaluate the existence of central sensitization syndrome in NCBP patients to determine the required pharmacological treatment.

The Role of 18F-FDG PET/CT in Predicting the Neoadjuvant Treatment Response in Patients with Locally Advanced Breast Cancer.

Purpose: Patients with locally advanced breast cancer (LABC) should be treated with neoadjuvant chemotherapy (NAC). Pathological complete response (pCR) is related to better disease-free survival (DFS). The best strategy for assessing the efficacy of NAC has not been established yet, but several studies have shown that 18F-FDG PET/CT is a potential imaging tool for assessing pCR. The aim of this study is to investigate the merits of 18F-FDG PET/CT imaging in predicting pCR in both axillary and breast tissue and to establish a threshold maximum standard uptake value (SUVmax) for predicting the response after completion of NAC. Methods: A total of 186 LABC patients, treated with an NAC regimen according to tumor subtype, were retrospectively analyzed in this study. All patients underwent 18F-FDG PET/CT imaging before and after completion of NAC. PET parameters were measured in the most FDG avid breast tissue and axillary lymph nodes. We analyzed the correlation between the tumor SUVmax of the PET/CT response and the pCR after surgery. DFS was also evaluated with respect to pCR. Results: Higher pCR rates were significantly associated with a higher tumor grade, an initial Ki-67 ≥20% (p = 0.03 and p = 0.003, respectively), a triple-negative subtype (32.9%), and a human epidermal growth factor receptor 2 (HER-2)-positive subtype (24.7%) (p < 0.001). There was a significant correlation between the pCR and a complete response in 18F-FDG PET/CT (p < 0.001). The overall sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of 18F-FDG PET/CT to determine the pCR after NAC were 100%, 72.2%, 85%, 75.2%, and 100%, respectively. We demonstrated a 1.1 cutoff SUVmax for breast tumors after NAC (OR: 3.94, 95% CI: 1.14-5.05, p = 0.004), the 18F-FDG PET/CT response to NAC (OR: 0.50, 95% CI: 0.25-0.99, p = 0.003), and the molecular subtype of breast tumors (OR: 0.58, 95% CI: 0.38-0.88, p = 0.011). Conclusion: Our results confirm that 18F-FDG PET/CT is a useful method for predicting the NAC response in LABC.

A Qualitative Analysis of Ostomy-Related Patient Education Videos on YouTube.

OBJECTIVE: To analyze the content, reliability, and quality of the most viewed YouTube videos targeting patients with ostomies intending to learn about ostomy care (OC). METHODS: Using the keywords "stoma care," "colostomy care," and "ileostomy care," researchers assessed the publicly visible English-language ostomy patient education videos available on YouTube. A total of 84 videos were independently analyzed by two physicians experienced in OC. Data on video characteristics, source, content, reliability, and quality were collected and recorded for each video separately. RESULTS: Of the 84 videos analyzed, 49 were classified as useful (58.33%) and 35 as misleading (41.66%). There were statistically significant differences between the groups in terms of the time elapsed since upload (P < .017), reliability (P < .001), comprehensiveness (P < .001), Global Quality Scale scores (P < .001), source (P < .001), and lecturer types (P < .011). The reliability, comprehensiveness, and Global Quality Scale scores were statistically higher for videos uploaded by universities, professional healthcare communities, and nonprofit physicians (P < .001). However, the popularity of the OC videos posted on YouTube was not related to their reliability, comprehensiveness, or quality. CONCLUSIONS: The open-access nature of the YouTube platform may impair patient education video quality and accuracy. YouTube may be an additional educational tool for OC, but clinicians need to be familiar with specific and reliable resources to guide and educate new patients with ostomies to achieve the best outcomes.

Comparison of Ultrasound-Guided Type-II Pectoral Nerve Block and Rhomboid Intercostal Block for Pain Management Following Breast Cancer Surgery: A Randomized, Controlled Trial.

PURPOSE: Although breast-conserving surgery-axillary dissection (BCS-AD) is a minimally invasive surgery, patients may suffer from moderate-to-severe pain. Several regional techniques can be used for pain control. The type II pectoral nerve block (PECS II) and the rhomboid intercostal block (RIB) are interfascial plane blocks that have been reported to provide effective analgesia after breast surgery. This study aims to compare the analgesic efficacy of the PECS II block and the RIB after breast surgery. PATIENTS AND METHODS: Ninety female patients aged 18 to 65 years with American Society of Anesthesiologists (ASA) classes I and II physical status who underwent unilateral BCS-AD surgery were included. Patients were divided into three groups (n = 30 in each): the PECS II group, the RIB group, or the control group. PECS II block and RIB were performed with 30 mL 0.25% bupivacaine. Ibuprofen 400 mg IV 3 × 1 was given in the postoperative period. A patient control analgesia device included a dose of 10 µg/mL fentanyl, which was prepared and connected to the patients. RESULTS: There were no statistical differences between groups in terms of demographical data. Postoperative fentanyl consumption was significantly lower in the PECS II and RIB groups than the control group. The need for rescue analgesia use was significantly higher in the control group than the other groups. At all times, visual analog scale scores were significantly lower in the PECS II and RIB groups than the control group. CONCLUSIONS: The PECS II block and the RIB provide similar effective analgesia after BCS-AD.

Self-reported medication adherence in differentiated thyroid cancer survivors: Role of illness perception and medication beliefs.

BACKGROUND: To investigate medication adherence (MA) to Levothyroxine in differentiated thyroid cancer survivors and analyze the related factors for nonadherence. METHODS: The Medication Adherence Report Scale (MARS), Hospital Anxiety and Depression Scale (HAD), Brief Illness Perception Questionnaire (B-IPQ), and Beliefs about Medicines Questionnaire (BMQ) were used to assess MA. RESULTS: Nonadherence was reported in 77 of 197 patients (39.1%). Socioeconomic status and education levels were found to be significantly related to MA. The HAD scores, all items of B-IPQ, and BMQ were associated with MA and showed a correlation with the MARS scores. The primary predictors of MA were greater confidence in treatment modality (odds ratio [OR]: 0.48, 95% confidence interval (CI): 0.37-0.63) and greater belief that the medication had minimal risk of harm (OR: 3.35, 95% CI: 1.50-7.49). CONCLUSIONS: Special attention should be paid to educational programs for differentiated thyroid carcinoma patients concerning the effectiveness and low risk of harm of medication in order to improve MA.

A Comparison of the Circulating Endocan Levels between the Inflammatory and Malignant Diseases of the Same Organ: The Breast.

PURPOSE: Idiopathic granulomatous mastitis (IGM) is a benign inflammatory breast disease that can clinically mimic breast carcinoma (BC). The aim of this study was to compare the endocan levels between inflammatory and neoplastic diseases of the breast, and to determine whether endocan is a convenient diagnostic biomarker for early stage BC and for the differentiation from IGM. MATERIAL AND METHODS: A total of 65 patients, consisting of 35 newly diagnosed with BC and 30 with IGM proven by core biopsies, and 20 healthy volunteer women with similar demographic characteristics were enrolled in the study. Endocan was assayed by a commercially available enzyme-linked immunosorbent assay kit. RESULTS: The endocan level was found to be significantly higher in the BC group than in the control group (p = 0.003). Although the endocan level was higher in the IGM group compared to the control group, there was no statistically significant difference (p = 0.057). No significant distinctive difference was observed between the BC and IGM groups in terms of the endocan level (p = 0.373). The serum endocan level was found to be positively correlated with BMI and vitamin D levels in the BC group (p = 0.043 and p = 0.023, respectively). CONCLUSIONS: We demonstrated that the serum endocan level was increased in patients with BC compared to healthy subjects, whereas in our enrolled study patient population, endocan was not a statistically valid biomarker for the differential diagnosis between BC and IGM. These findings indicate the potential role of endocan in the pathogenesis of BC.

Can Traditional Fermented Food Products Protect Mothers Against Lactational Mastitis.

Background/Objective: Various dietary factors, including the daily food intake during pregnancy and lactation can play a role in the development of lactational mastitis (LM). To investigate the effect of the most commonly consumed fermented foods (FF) during pregnancy and lactation in Turkey and other factors described in the literature regarding childbirth and breastfeeding on the development of LM. Materials and Methods: The study included 607 volunteers in the lactational period, of whom 303 had LM and 304 had no mastitis event. The data on sociodemographics, childbirth, and breastfeeding, and the consumption frequency of six types of FF were collected through a face-to-face questionnaire. Results: The variables significantly and independently associated with LM were birth week (odds ratio [OR] = 80.83, 95% confidence interval [CI]: 1.12-1.94), birth weight (OR = 0.63, CI: 1.24-1.79), time to breastfeeding after birth (OR = 0.79, CI: 1.62-2.31), breastfeeding length (OR = 0.12, CI: 2.25-2.78), breast preference (OR = 0.13, CI: 2.83-3.42), use of cream on nipples (OR = 0.81, CI: 1.31-1.97), use of oral probiotics (OR = 0.29, CI: 1.86-2.92), and receiving breastfeeding education from an expert (OR = 0.22, CI: 1.22-2.34). According to the multinominal logistic regression analysis, the daily consumption of kefir (OR = 0.69, CI: 1.18-2.22), homemade yogurt (OR = 0.78, CI: 1.14-1.87), conventional yogurt (OR = 0.81, CI: 1.24-2.46), boza (OR = 0.79, CI: 2.19-2.99), tarhana (OR = 0.52, CI: 2.47-2.81), and pickles (OR = 0.22, CI: 1.22-2.34) significantly reduced the risk of LM development. The diversity of consumed FF was also found to be protective against LM (OR = 0.34, CI: 1.34-2.35). Conclusion: Kefir, homemade and conventional yogurt, boza, tarhana, and pickles can protect breastfeeding mothers and also reduce the risk of LM development.

Demographic and Clinical Features of Hidradenitis Suppurativa in Turkey.

BACKGROUND: The literature contains conflicting reports on the epidemiology and frequency of hidradenitis suppurativa (HS), a chronic, recurrent inflammatory disease of the apocrine glands. OBJECTIVE: To evaluate the clinical and demographic characteristics of HS cases in Turkey and investigate the similarities with world epidemiology. METHOD: The records of 208 patients that presented to our polyclinics and were diagnosed with HS between June 2012 and July 2017 were retrospectively evaluated. RESULTS: Of the cases, 68.3% were male and 31.7% were female. Of the patients, 75.5% had no family history of HS, 60.6% were smokers, 39.4% were aged 20-29 years, and 36.1% were aged 30-39 years. The most commonly involved regions were the axilla (62%), groin (50.5%), and gluteus (15.9%). According to univariate analyses, male patients had higher disease stages than females (odds ratio=1.67). The patients with groin involvement, high body mass index (BMI), and low education level (0-8 years) had higher risk of severe disease stage (odds ratio=1.63, 8.91, and 1.51, respectively). The most commonly used treatment was oral antibiotics in Hurley stages I and II, and surgical intervention in Hurley III. In all 3 Hurley stages, clavulanic acid-amoxicillin combination was the mostly used systemic antibiotic (41.8%, 43.2%, and 47.8%, respectively). CONCLUSIONS: This is the first epidemiological study on HS in the Turkish population, where HS shows male predominance. Male gender, low education level, absence of acne, high BMI, and groin involvement were associated with severe disease stages. Determining associated comorbidities and possible risk factors is important in progression and prevention of the disease.

The effect of fibrin glue in preventing staple-line leak after sleeve gastrectomy. An experimental study in rats.

PURPOSE: To evaluate the effect of fibrin glue on staple-line leak after sleeve gastrectomy. METHODS: Fourteen adult wistar rats 300 gr were randomized into two groups: Control group (n=7) and study group (n=7). All the rats underwent sleeve gastrectomy using lineer stapler. In the study group, fibrin glue was used to reinforce the staple-line. The rats were sacrificed 7 days after surgery. The stomach was resected, submerged in saline and exposed to excess pressure to obtain a burst pressure value. The gastric staple line was evaluated histopathologically according to the Ehrlich Hunt scale. The results of the two groups were compared. RESULTS: The mean Ehrlich-Hunt scores for inflammation, fibroblastic activity and neo-angiogenesis were similar between the groups (p>0.05). Collagen deposition was significantly higher in study group (3.42±0.53) when compared with control group (2.57±0.78) (p=0.035). The mean burst pressure was 137.8±8.5 mmHg for control group and 135.0±8.1 mmHg for study group (p=0.536). CONCLUSION: Reinforcement of the staple-line with fibrin glue has no effect on the burst pressure after sleeve gastrectomy. More studies are needed to evaluate the precautions against leak after sleeve gastrectomy.
