Efficacy of Serratus Posterior Superior Intercostal Plane Block on Postoperative Pain and Total Analgesic Consumption in Patients Undergoing Reduction Mammoplasty Surgery: An Evidence Based Report.

Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that provides analgesia in shoulder, hemithorax and in the back of the neck. In this study, the efficacy of this block on postoperative pain and quality of recovery is reported in ten consecutive patients who had undergone reduction mammoplasty. Blocks were performed bilaterally with 30 ml 0.25 % bupivacaine for each side, at the end of surgery. Cumulative tramadol consumption and numerical rating scale (NRS) scores during rest (static) and coughing (dynamic) were assessed within the first postoperative 24 hours. Mean total tramadol consumption was 39 ±9.94 mg. NRS scores above 4 were observed in 5 patients in the dynamic NRS assessment at the postoperative 1st hour, while static and dynamic NRS scores were ≤4 at other durations. SPSIPB may play a part in postoperative multimodal analgesia following mammoplasty in the future and may reduce total analgesic consumption.

Effects of Modified Thoracoabdominal Nerve Block Through Perichondrial Approach on Postoperative Pain and Analgaesic Consumption in Patients Undergoing Laparoscopic Cholecystectomy.

OBJECTIVE: To investigate postoperative analgaesic efficacy of modified thoracoabdominal nerve block through perichondrial approach (M-TAPA) and its effect on opioid consumption in patients undergoing laparoscopic cholecystectomy (LC) surgery. STUDY DESIGN: Randomised, controlled trial. Place and Duration of the Study: Department of Anaesthesiology and Reanimation, Sivas Cumhuriyet University, Sivas, Turkiye, from April to May 2023. METHODOLOGY: The study was conducted in two randomised groups: M-TAPA (n = 21) and control group (CG) (no block) (n = 21). All patients had standard general anaesthesia. M-TAPA patients had bilateral M-TAPA block with 0.25% bupivacaine (total volume, 40 ml) at the end of the surgery. In contrast, CG patients had only tramadol for postoperative pain. A numerical rating scale (NRS) and visual analogue scale (VAS) were used for postoperative pain assessment. Total tramadol consumption was calculated. RESULTS: M-TAPA's NRS and VAS scores were lower in postoperative 24 hours (p<0.05). Total tramadol consumption was 116.67 ± 32.91 mg in CG and 35.71 ± 39.19 mg in M-TAPA (p<0.001). CONCLUSION: Bilateral M-TAPA block for postoperative pain control after LC surgery provided effective analgaesia for up to 24 hours and reduced total opioid consumption. Although the M-TAPA block is a novel approach, it will be a part of multimodal analgaesia for routine postoperative pain management in abdominal surgeries. However, more studies with higher numbers of patients will be needed. KEY WORDS: Analgaesia, Bupivacaine, Laparoscopic cholecystectomy, Nerve block, Pain management.

Increased Serum Systemic Immune-Inflammation Index is Independently Associated With Severity of Carotid Artery Stenosis.

Stroke is a significant contributor to morbidity and mortality. The present study investigated how the systemic immune inflammation index (SII) could be used to predict the likelihood of developing carotid artery stenosis (CAS), which can be seen using carotid artery angiography (CAAG). This study comprised 418 individuals who underwent CAAG for CAS. SII was calculated by multiplying the platelet count by the neutrophil/lymphocyte ratio (NLR). The patients were divided into two groups: non-critical and critical CAS (stenosis below %70 and above ≥70%, respectively). Compared with the non-critical CAS, the critical CAS group had greater high sensitivity C-reactive protein levels (4.5 [3.1-5.7] vs 3.9 [2-5] [mg/L], P < .001), NLR (4.1 [2.9-7.5] vs 2.9 [1.8-3.7], P < .001), platelet/lymphocyte ratio (233 [110-297] vs 119 [96-197], P < .001), and SII (860 [608-2455] vs 604 [458-740], P < .001). Receiver Operating Characteristic Curve analysis demonstrated the best cutoff value of 672.3 for SII to predict the critical CAS with 71.2% sensitivity and 60.1% specificity. According to our study, an increase in SII is an independent predictor of the severity of CAS in patients undergoing CAAG.

Efficacy of serratus posterior superior intercostal plane block (SPSIPB) on post-operative pain and total analgesic consumption in patients undergoing video-assisted thoracoscopic surgery (VATS): A double-blinded randomised controlled trial.

Background and Aims: Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that can provide analgesia in the hemithorax, shoulder, and back of the neck. This study aimed to evaluate the post-operative analgesic effect of SPSIPB in patients undergoing video-assisted thoracoscopic surgery (VATS). Methods: It is a double-blind, randomised controlled trial. Twenty-four adult patients who underwent VATS via the uniportal technique were randomised into two groups: the SPSIPB group (n = 12) received SPSIPB along with intravenous patient-controlled analgesia (PCA) with tramadol, whereas the control group (n = 12) received only PCA with tramadol. At the end of the surgery, patients in the SPSIPB group received a unilateral SPSIPB under ultrasound guidance with the use of 30-mL bupivacaine 0.25%. The primary outcome was the numerical rating scale (NRS) scores of the patients. Secondary outcomes included the amount of tramadol and rescue analgesic (paracetamol) consumed by the patients, followed up for post-operative 24 hours. Categorical variables were compared using the Chi-Square Test. Mann-Whitney U Test was used to compare groups of variables that were not normally distributed. Results: The SPSIPB group had lower NRS values during post-operative 24 hours (P < 0.001). Mean (standard deviation) total tramadol consumption was 58.33 (26.23) mg in the SPSIPB group and 144.17 (13.11) mg in the control group (P < 0.001). Rescue analgesic need was lower in the SPSIP group in the first 18 post-operative hours (P < 0.05). Conclusion: Serratus posterior superior intercostal plane block provides good analgesia in the thoracic region after video-assisted thoracoscopic surgery.

Clinical Factors Affecting the Therapeutic Efficacy of Evening Primrose Oil on Mastalgia.

BACKGROUND: Saturated fatty acid esters may cause mastalgia via hypersensitivity of breast epithelium to circulating hormones. Evening primrose oil (EPO) may restore the saturated/unsaturated fatty acid balance and decrease sensitivity to steroidal hormones or prolactin. Conflicting results exist regarding EPO treatment for mastalgia. The aim of this study was to determine the effectiveness of EPO and factors affecting its efficacy in treatment of mastalgia. METHODS: The study included 1015 patients, ages 14-82 (mean age 42.21 ± 10.8), admitted to Acibadem Breast Clinic between January 2015 and March 2018. The patients were divided into group I (n = 581) treated with EPO (1300 mg, twice a day) and group II (n = 434) treated with paracetamol (500 mg, twice a day). The visual analog scale was used to assess EPO's therapeutic efficacy, compared with paracetamol, measured at admittance, 2 weeks, and 6 weeks. Clinical factors affecting the efficacy of EPO were analyzed. RESULTS: The therapeutic efficacy of EPO on mastalgia was significantly higher than with paracetamol (p < 0.001). Factors significantly affecting the efficacy of EPO treatment were hormone replacement therapy (HRT), IUD-with-levonorgestrel, iron deficiency, overt hypothyroidism, and Hashimoto thyroiditis (p < 0.01). Replacement of iron or thyroid hormone efficiently treated mastalgia in patients that did not respond to EPO treatment. Side effects (allergy, anxiety, blurred vision, constipation, and nausea) were rare and not statistically significant (p = 0.88). CONCLUSION: EPO can be used in the treatment of mastalgia without significant side effects. HRT, IUD-with-levonorgestrel, iron deficiency, overt hypothyroidism, and Hashimoto thyroiditis significantly affect the efficacy of EPO on mastalgia.

Oncologic safety of nipple-sparing mastectomy in patients with short tumor-nipple distance.

BACKGROUND: There is a tendency to avoid nipple-sparing mastectomy (NSM) when a tumor-nipple distance (TND) is <2 cm due to the risk of occult nipple involvement. The purpose of the study was to determine whether the patients who undergo NSM with immediate reconstruction are oncologically safe when TND is <2 cm. METHODS: Patients who underwent NSM followed by immediate reconstruction for breast cancer were retrospectively analyzed. Patients who are negative for nipple-base in either frozen-section or paraffin histopathology were included. MRI was used to obtain TNDs to compare local-recurrence-free and disease-free survival in group I (TND <2 cm) and group II (TND ≥2 cm). Disease-free survival rates were determined to assess the outcome. RESULTS: Of the 214 cases with malignancy on MRI, 21 cases diagnosed with pure ductal carcinoma in situ were excluded. Among the 193 NSM cases diagnosed with invasive cancer, TND was <2.0 cm in 59 (30.56%) cases and ≥2.0 cm in 134 (69.43%) cases. No significant differences were found between groups in regards to ER, PR, HER2-neu status, and nodal involvement (P = 0.34, P = 0.41, P = 0.54, and P = 0.12 respectively). In a median follow-up time of 62 months (range; 13-114), patients in group I had four local recurrences, whereas group II was found to have five local and three distant metastases. No significant differences were observed between groups concerning disease-free survival (10-year DFS 93.2% vs 96.3%; P = 0.368 respectively). CONCLUSIONS: Patients who have invasive cancer diagnosis with a TND <2 cm are eligible to undergo therapeutic NSM with immediate reconstruction.

Is human papillomavirus associated with breast cancer or papilloma presenting with pathologic nipple discharge?

PURPOSE: There are little data on the presence or interaction of human papillomavirus (HPV) in intraductal papilloma or Breast cancer (BC) presenting with pathologic nipple discharge (PND). The study aimed to determine whether the HPV-genotypes are identifiable in papilloma or carcinoma of the breast by real-time PCR with broad-spectrum genotyping. METHODS: Formalin-fixed-paraffin-blocks obtained from the patients who were suffering from PND and underwent ductoscopic papilloma extraction (n = 27) or segmental/total mastectomy for cancer diagnosis (n = 18). HPV-DNAs were identified by PCR with broad-spectrum genotyping. Mc Nemar test was used to compare cancer-involved cases to normal-adjacent tissue concerning HPV positivity. Chi-Square test was used to analyze the association for receptor status in HPV positive cancer-involved cases. RESULTS: The mean age (±SD) was 49 ± 16 in papilloma and 52 ± 14 in BC patients, respectively. We found high prevalence of HPV in papilloma and carcinoma: 29.6% (n = 8) and 44.4% (n = 8), respectively. The most common type identified in breast lesions was HPV-11, and the others were HPV- 6, -11, -39, and -82. Cancer-involved samples were more contaminated by HPV in comparison to normal-adjacent tissues (p = 0.016). In HPV positive cancer-involved cases, hormone receptors were found to be more positive than HER2-Neu (p = 0.035). CONCLUSIONS: Our data suggest that HPV might be a causative agent for the development of papilloma and carcinoma of the breast in some cases presenting with PND. HPV positive breast cancers are more likely to be hormone positive. Further studies needed for validation regarding the integration of HPV-DNAs into the human genome that causes BC.

The role of molecular biomarkers for predicting adjacent breast cancer of Atypical Ductal Hyperplasia diagnosed on core biopsy.

BACKGROUND: Atypical Ductal Hyperplasia (ADH) is a disease of the proliferative breast lesion characterized with atypia and when diagnosed on core needle biopsy (CNB), excisional biopsy is the current management to exclude adjacent cancer, which may found 10 to 20%. OBJECTIVE: The purpose of the study is to investigate the role of biomarkers on surgical decision after the diagnosis of ADH on CNB. METHODS: Patients with pure ADH on core biopsy were retrospectively selected, and categorized according to final pathology after excision into three groups: Group I (n: 39) ADH; Group II (n: 27) ductal carcinoma in situ (DCIS), and Group III (n: 9) invasive cancer (IC). Immunohistochemical analyses were performed using biomarkers MUC1, Ki67, Cyclin B1, and Cyclin D1. RESULTS: Only Cyclin D1 was significant in between group analysis by one-way ANOVA (64.74, 49.44, and 51.11, respectively; p= 0.01). However when appropriate cut-off levels (2%-50%) were used for each biomarkers using X2 test, no statistical significance was found. CONCLUSION: MUC1, Ki67, Cyclin B, and Cyclin D1have failed to predict adjacent cancer on core biopsy specimens with ADH. Further surgery is warranted for all ADH cases diagnosed on core biopsies until a new predictor is identified.

Comparison of the Effects of Intrathecal Fentanyl and Intrathecal Morphine on Pain in Elective Total Knee Replacement Surgery.

Objective. Total knee replacement is one of the most painful orthopedic surgical procedures. In this study, our goal was to compare the intraoperative and postoperative hemodynamic effects, the side effects, the effect on the duration of pain start, the 24-hour VAS, and the amount of additional analgesia used, of the fentanyl and morphine we added to the local anesthetic in the spinal anesthesia we administered in cases of elective knee replacement. Materials and Methods. After obtaining the approval of the Erciyes University Medical Faculty Clinical Drug Trials Ethics Committee, as well as the verbal and written consent of the patients, we included 50 patients in our prospective, randomized study. Results. In our study, the morphine group (Group M) had lower pain scores in the 2nd, 6th, 12th, and 24th hours compared to the fentanyl group (Group F). When additional analgesic requirements were compared, it was found that in the 2nd, 6th, and 24th hours fewer Group M patients needed more analgesics than did Group F patients. Conclusion. The fentanyl group also had lower first analgesic requirement times than did the morphine group. In terms of nausea and vomiting, there was no statistically significant difference between the two groups.

Improving the color of bulgur: new industrial applications of tempering and UV/sun-light treatments.

Color (CIE b*; yellowness) is an important parameter for bulgur quality. Color of bulgur is mainly due to natural pigments (carotenoids) that are present at different levels in wheat. In order to increase the customer acceptability, the producers try to obtain yellowish color in bulgur. In this study, two different tempering methods (spray and steam) were used before sun and UV- light polishing applications. Sun and UV-light were applied to tempered bulgur for 12, 24, 36, 48, 60 and 72 h. Moisture content (%, d.b.), ash content (%, d.b.), protein content (%, d.b.), total carotenoid content in terms of lutein equivalent (TCC) and color values (CIE L*; lightness, CIE b*; yellowness, CIE a*; redness and CIE YI; yellowness index) were determined. It was found that UV-light was more effective (P < 0.05) on the CIE L* and CIE b* values compared to sunlight. Both tempering methods were significantly (P < 0.05) increased the CIE L*, CIE b* and CIE YI values. Steam tempering has a significant effect (P < 0.05) on the CIE b* values as well as UV and time of UV exposure. The highest value of TCC i.e. 6.31 µg/g was obtained by using spray tempering and UV-light exposure. As a conclusion, as proposed methods steam tempering and UV-light have an obvious positive effect on the color of bulgur.

Single Institution Experience with Lymphatic Microsurgical Preventive Healing Approach (LYMPHA) for the Primary Prevention of Lymphedema.

BACKGROUND: As many as 40 % of breast cancer patients undergoing axillary lymph node dissection (ALND) and radiotherapy develop lymphedema. We report our experience performing lymphatic-venous anastomosis using the lymphatic microsurgical preventive healing approach (LYMPHA) at the time of ALND. This technique was described by Boccardo, Campisi in 2009. METHODS: LYMPHA was offered to node-positive women with breast cancer requiring ALND. Afferent lymphatic vessels, identified by injection of blue dye in the ipsilateral arm, were sutured into a branch of the axillary vein distal to a competent valve. Follow-up was with pre- and postoperative lymphoscintigraphy, arm measurements, and (L-Dex®) bioimpedance spectroscopy. RESULTS: Over 26 months, 37 women underwent attempted LYMPHA, with successful completion in 27. Unsuccessful attempts were due to lack of a suitable vein (n = 3) and lymphatic (n = 5) or extensive axillary disease (n = 1). There were no LYMPHA-related complications. Mean follow-up time was 6 months (range 3-24 months). Among completed patients, 10 (37%) had a body mass index of ≥30 kg/m(2) (mean 27.9 ± 6.8 kg/m(2), range 17.4-47.6 kg/m(2)), and 17 (63%) received axillary radiotherapy. Excluding two patients with preoperative lymphedema and those with less than 3-month follow-up, the lymphedema rate was 3 (12.5%) of 24 in successfully completed and 4 (50 %) of 8 in unsuccessfully treated patients. CONCLUSIONS: Our transient lymphedema rate in this high-risk cohort of patients was 12.5%. Early data show that LYMPHA is feasible, safe, and effective for the primary prevention of breast cancer-related lymphedema.

Decision making and factors influencing long-term satisfaction with prophylactic mastectomy in women with breast cancer.

PURPOSE: Studies demonstrate an increasing rate of contralateral prophylactic mastectomy (CPM). The purpose of this study is to evaluate decision making and factors influencing women's long-term satisfaction with CPM. Descriptive analysis is used to analyze the results of our designed questionnaire approved by our Institutional Review Board. METHODS: We searched our institutional cancer registry for patients diagnosed with breast cancer between 2000 and 2010. The studied time frame is of significance as this study is the first to measure response rate in questions examining patient satisfaction for >1 year after undergoing CPM. The questionnaire was mailed to all consented participants to examine factors contributing to the choice of CPM and postoperative satisfaction. RESULTS: Of the 206 women included in the study, 147 were aged up to 50 years. Majority of women who underwent CPM in this cohort was with a bachelor's degree or higher, married or partnered women, and women earning >$60,000/y. Almost all women were "happy with overall surgery" and would recommend CPM to other patients. Psychological factors, such as fear of recurrence, were more commonly associated with the decision for CPM in patients with invasive carcinoma. Opinions of partners, relatives, friends, and physicians further contributed to the decision to undergo surgery. The availability of reconstruction was also an influential factor in the overall decision. CONCLUSIONS: The majority of our study participants experienced long-term satisfaction with the surgical procedure of CPM. From our analysis, we can confidently say that fear of cancer recurrence and the opinions of others, among other factors, were influencing contributors toward the decision of undergoing CPM.

Exploring breast with therapeutic ductoscopy.

Breast lesions are thought to arise mostly from the epithelium of ductal lining. Conventional imaging could only show indirect images of suspected lesions which are confirmed by percutaneous biopsies. However, ductoscopy provides direct images of the ductal epithelium which is the source of most malignant and papillary lesions. As an advance of current ductoscopy systems, pathologic nipple discharge (PND) could be treated ductoscopically by miniaturized endo-baskets or wires. Our goal is to discuss current intraductal technology which enables diagnostic and therapeutic advance for breast lesions that cause nipple discharge.

Interventional ductoscopy for pathological nipple discharge.

BACKGROUND: Despite the low likelihood of malignancy, it is recommended that patients who have pathologic nipple discharge (PND) undergo duct excision. Intraductal papilloma is well-known most frequent cause of PND. Our goal is to determine whether the ductoscopic retrieval of a solitary papilloma is feasible and/or therapeutic for patients with PND. The accompanying video demonstrates this interventional ductoscopic approach. METHODS: Consented patients who had been diagnosed with PND were recruited to have ductoscopic exploration. Patients with palpable masses and suspicion of malignancy on ultrasound or mammography were excluded. Under local anesthesia, ductoscopy was performed using LaDuScope-T flex with an outer diameter of 1.1 mm, which allows extraction of a single papilloma with a microbasket (380 µm) via a working channel. Patients with sessile single papilloma or failure on ductoscopic extraction underwent ductoscopically guided microductectomy. Success was determined by recurrence of PND and by standard radiological examinations. RESULTS: Three patients presented in the video had negative cytology and normal conventional diagnostic imaging. Two patients diagnosed with a nonsessile single papilloma underwent successful ductoscopic extraction. The interventional examination times of those patients were 30 and 35 min. Patient who had a sessile papilloma underwent ductoscopically guided microductectomy. These patients had no recurrence of discharge or suspicious of malignancy after 5 years follow-up. CONCLUSIONS: Interventional ductoscopy provides an incisionless therapeutic option for patients diagnosed with a papillary nonsessile benign lesion that causes PND.

Optimizing surgical margins in breast conservation.

Adequate surgical margins in breast-conserving surgery for breast cancer have traditionally been viewed as a predictor of local recurrence rates. There is still no consensus on what constitutes an adequate surgical margin, however it is clear that there is a trade-off between widely clear margins and acceptable cosmesis. Preoperative approaches to plan extent of resection with appropriate margins (in the setting of surgery first as well as after neoadjuvant chemotherapy,) include mammography, US, and MRI. Improvements have been made in preoperative lesion localization strategies for surgery, as well as intraoperative specimen assessment, in order to ensure complete removal of imaging findings and facilitate margin clearance. Intraoperative strategies to accurately assess tumor and cavity margins include cavity shave techniques, as well as novel technologies for margin probes. Ablative techniques, including radiofrequency ablation as well as intraoperative radiation, may be used to extend tumor-free margins without resecting additional tissue. Oncoplastic techniques allow for wider resections while maintaining cosmesis and have acceptable local recurrence rates, however often involve surgery on the contralateral breast. As systemic therapy for breast cancer continues to improve, it is unclear what the importance of surgical margins on local control rates will be in the future.

Gamma probe (99m)Tc-pertechnetate assisted completion thyroidectomy vs conventional thyroidectomy in differentiated thyroid carcinoma.

Patients undergoing partial thyroidectomy for benign diseases may need re-operation if differentiated thyroid carcinoma (DTC) is detected on histopathology. The aim of this study was to determine if using gamma probe during the above surgery in a procedure called: gamma probe completion thyroidectomy (GPCT) could support the diagnosis of DTC tissue and offer an advantage in the surgical treatment of DTC patients. We have studied 100 patients who after bilateral subtotal thyroidectomy for benign disease in several hospitals, were found to have DTC histopathologically and referred to our clinic for subsequent re-operation. Of these, 50 underwent conventional completion thyroidectomy (Group I) and 50 underwent GPCT (Group II). We compared retrospectively Group I and Group II in terms of volume of residual thyroid tissue, thyroid stimulating hormone (TSH) values, complication rates and incidence of tumor found in the residual thyroid. Our results showed that one month postoperatively, TSH was significantly higher in Group II (P<0.001). Volumes of residual thyroid were also significantly less in Group II (P<0.000). Complications and the incidence of tumor cells found in the residual thyroid tissue between the groups were not statistically different (P>0.05). In conclusion, GPCT in patients with DTC significantly increased the success of this operation in localizing and removing residual thyroid tissue.

Systemic inflammatory response after Kugel versus laparoscopic groin hernia repair: a prospective randomized trial.

BACKGROUND: Kugel repair, a minimally invasive technique, has become an alternative to laparoscopic groin hernia repair, but the technique has not been adequately evaluated by assessment of objective parameters. A prospective randomized clinical study was carried out to compare the systemic inflammatory response to surgical trauma and clinical outcomes in patients who underwent groin hernia repair by the Kugel and totally extraperitoneal (TEP) laparoscopic methods. METHODS: Forty consecutive patients admitted for unilateral groin hernia were randomized to Kugel (n = 20) or TEP (n = 20) repair under general anesthesia. Operation time, length of hospital stay, pain severity, time to return to normal activities, cost, and systemic inflammatory and hormone responses to surgical trauma were compared. RESULTS: There were no significant between-group differences in duration of operation, length of hospital stay, time to return to normal activities, or mean visual analogue scale (VAS) score (p > 0.05 for each). Serum cortisol, high-sensitivity C-reactive protein (hsCRP), and interleukin (IL)-6 concentrations before surgery, and 1 and 24 h after surgery, did not differ significantly in the two groups (p > 0.05). There were no recurrences or complications during follow-up. Cost per patient was US $546 lower in the Kugel group. CONCLUSION: Kugel herniorrhaphy is a minimally invasive technique that offers all the advantages of TEP and is more cost-effective.
