Estimating the effects of the anesthesia method on delirium contributes to the prevention of possible complications. In this study, effects due to use of different anesthesia methods on the post-operative delirium development in geriatric patients who underwent orthopedic surgery were investigated.\u0000Methods: In our retrospective cohort study, scanning of the patient files was performed for 276 patients who were older than 65 years and who had undergone surgery for lower extremity fractures in Malatya education and research hospital, orthopedics department between May 1, 2022 and October 15, 2022. Demographic data, comorbid conditions, anesthesia type, lengths of surgery, and level of delirium development were recorded for each scanned patient.\u0000Results: In our study, 201 patients were included. The mean age of the patients was 74.1 (7.3) (min–max: 65–98); 133 (66.2%) were female, and 68 (33.8%) were male. It was noticed that patients who had undergone regional anesthesia developed a significantly smaller rate of delirium development (8.1%) compared to those who had received general anesthesia (20.6%; P=0.012). Ages (P<0.001), lengths of surgery (P<0.001), and lengths of hospitalization stays (P<0.001) were significantly higher in patients with delirium compared to those without.\u0000Conclusion: Based on the data obtained in this study, it was concluded that to reduce the risk of delirium development after orthopedic surgery, regional rather than general anesthesia should be selected, and the time of hospitalization stay should be minimized.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91263081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, insufficient data supports the routine use of TXA in arthroscopic meniscectomy. This study aimed to evaluate the effect of a single dose of intravenous (IV) TXA on visual clarity in arthroscopic meniscectomy without a tourniquet. \u0000Methods: A randomized, double-blind, controlled trial was conducted to assess the use of TXA for visibility in routine arthroscopic meniscectomy without a tourniquet. Between January 2021 and February 2022, 53 patients undergoing arthroscopic meniscectomy were randomly assigned to either the TXA group (n=27), who received 1 g IV-TXA, or the control group (n=26), who received 100 ml of normal saline. Visual clarity was evaluated using a Numeric Rating Scale (NRS). Patients were also assessed for the need for a tourniquet, tourniquet time, total operative time, volume of irrigation fluid, postoperative pain, hemarthrosis, and knee function on postoperative day 3 and weeks 1, 2, and 4, using the Lysholm knee scoring scale. \u0000Results: There was no significant difference in intra-operative arthroscopic visibility between the TXA and control groups (P=0.394).

Immune-based scores, such as the neutrophil-lymphocyte and the platelet-lymphocyte ratios (NLR and PLR, respectively) have been suggested as predictors of inflammation and prognosis in SLE. This study aimed to investigate the value of the systemic immune-inflammation index (SII), inflammatory prognostic index (IPI), and systemic inflammatory response index (SIRI) in SLE and lupus nephritis (LN).\u0000Methods: This case-control study consisted of 108 newly diagnosed SLE patients (separated into two subgroups, which included 34 patients with biopsy-proven LN and 74 without nephritis) and 108 age- and gender-matched healthy controls who presented to our outpatient clinic between October 2015 and June 2020. Patients with malignancy, lymphoproliferative and hematologic disorders, active infection, and autoimmune diseases other than SLE were excluded. Inflammation-based biomarkers were calculated at the first presentation of the disease and before any medication was administered. SII was calculated as Neutrophil/Lymphocyte x Platelet, SIRI as Neutrophil x Monocyte/Lymphocyte, and IPI as CRP x NLR/serum albumin. The Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) was used to measure disease activity. The capability of SII, SIRI, NLR, PLR, and IPI to distinguish between SLE patients with or without nephritis was assessed using receiver operating characteristic (ROC) curves. Correlations of inflammation-based scores (SII, SIRI, IPI, NLR) with disease activity and laboratory data of SLE patients were analyzed.\u0000Results: SII, SIRI, and IPI were significantly higher in SLE patients than in healthy controls (P=0.003, P=0.019, and P<0.001, respectively) and also significantly higher in patients with nephritis than in those without (P<0.001, P=0.009, and P=0.007, respectively). The area under the curve (AUC) for SII, SIRI, and IPI in terms of differentiating SLE patients with or without nephritis was 0.748, 0.690, and 0.663, respectively. The cut-off value of SII, SIRI, and IPI to predict LN was 552.25 (sensitivity: 64.7%; specificity: 64.9%; P<0.001), 1.08 (sensitivity: 61.8%; specificity: 62.2%; P=0.002), and 4.48 (sensitivity: 61.8%; specificity, 62.2%; P=0.007), respectively.\u0000Conclusion: SII, SIRI, and IPI may be valuable and promising inflammation-based biomarkers in SLE and for the presence of nephritis in SLE patients.

Histological findings determine their management. Here we compare volumetric apparent diffusion coefficient (ADC) histogram analysis of carcinomas and benign pathologies identified by histopathology from excisional biopsies.\u0000Methods: This retrospective study included 524 patients who underwent breast magnetic resonance imaging (MRI) for a suspicious breast mass from January 2018 to October 2022. Patients with benign lesions, incompatible ultrasound-guided CNB results with papillary neoplasia, and those with MRI exams insufficient for diagnosis due to motion artifacts were excluded. After applying the exclusion criteria, the study included 48 patients (average aged 61.5 (14.8) years; range, 31 to 72 years). After excisional biopsies, 30 benign lesions and 18 carcinomas were identified. MRI was acquired at 1.5 T (Verio; Siemens Medical Solutions, Erlangen, Germany), and the b-values for diffusion-weighted imaging were calculated at 1000 s/mm2. Histogram parameters were computed. Receiver operating characteristic (ROC) curve analysis was performed to investigate diagnostic accuracy, evaluate histogram analysis performance, and determine threshold values.\u0000Results: The ADCmin, ADCmean, ADCmax, and all ADC value percentiles were significantly lower in the carcinoma group than in the benign group (P<0.001).

Although studies have shed light on the relationship between the factors affecting the healing process after fracture, this process is still not fully understood. In this study, we aimed to investigate the changes in serum biomediator levels and fracture healing in different trauma patterns, such as head trauma (HT), long bone fracture (LBF), a combination of HT + LBF injury (CI), and in different time points of the healing period. \u0000Methods: Forty Wistar rats were included in the study and divided into five groups. Group 1, the donor group, included rats with HT; Group 2 included rats with LBFs who were administered the serum taken from rats in Group 1; Group 3 included the rats with isolated LBFs; and Group 4 the rats with CI. Group 5 comprised the control rats. An experimental closed HT and fracture model was applied to rats. The rats in Groups 2, 3 and 4 were sacrificed on the 10th, 20th, and 30th days. The biomediator levels in the serum taken after sacrification were studied, while closed femoral fracture models were examined radiologically. \u0000Results: Statistically significant differences were found among the groups regarding radiological scores on the 10th, 20th, and 30th days. On Day 10, Group 2a had significantly higher scores than Group 3a (P=0.03), and Group 3a had lower scores than Group 4a (P=0.01). On Day 20, Group 2b had significantly higher scores than Group 3b (P=0.004) but lower than Group 4b (P=0.03). On Day 30, Group 2c had significantly higher scores than Group 3c but lower than Group 4c (P=0.001). The mean Ca, TGF beta 1, beta-catenin, IL-10, IL-17A, TNF alpha, CRP, Wnt-16, ALP, GH, PTH, IL-1 beta, IL-6, and IL-22 levels were significantly different among the groups (P<0.05). No significant difference was observed in the biomediator levels among the groups at different time points of the healing period. \u0000Conclusion: We concluded that inflammatory cytokines (IL-1 beta, IL-6, IL-17A, IL-17F, IL-23, and TNF alpha) were elevated in the early period in individuals with isolated head trauma and that this effect could be transferred to other individuals by serum transfer. On the other hand, the negative relationship between the IL-10 level, which is a negative modulator in fracture union, and callus thickness was significant. Our study contributes by providing a molecular description of the positive union effect transferred between individuals by serum. We believe our findings will play a significant role in developing new therapeutic agents for fracture healing.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87543420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to summarize the cases in which graded motor imagery therapy is used, study protocols, and outcome measures in studies.\u0000Methods: The literature search was done with Web of Science, Pubmed, Scopus, and PEDro databases. The last search was carried out on September 13, 2022. A series-specific bias risk assessment tool was used with randomized, non-randomized, and case reports. All clinical studies that performed graded motor imagery, available in full text, describing their methods and findings, were included. The gender of the participants was not significant. The intervention was graded motor imagery. Outcome measures were mainly pain severity, other pain-related measures (e.g., pressure pain threshold, pain catastrophe), range of motion, strength, reaction time, kinesiophobia, neurophysiological measures, depression, function, or quality of life measures.\u0000Results: Complex regional pain syndrome, distal radius fracture, phantom limb pain, stroke, cancer, pathological pain (phantom pain after amputation, pain after brachial plexus avulsion), elbow stiffness, frozen shoulder, chronic shoulder pain, and osteoarthritis conditions were included. The intervention duration in the studies varies from 2 to 8 weeks. A common outcome measure could not be determined among studies. The pain was assessed in 15 studies, although different rating scales were used. Graded motor imagery resulted in a reduction in pain in 14 of the 15 studies.\u0000Conclusions: Due to the heterogeneity of the studies, a general conclusion regarding the effect of the disease-specific intervention was not possible.

One of the tests used in latent TB screening is the interferon gamma release test. In rheumatology practices, it is routinely used to screen for latent tuberculosis infections before treatment with biological agents and Janus kinase (JAK) inhibitors, and it can also be used to exclude tuberculosis infection in clinical practice. In our study, we aimed to evaluate the reasons for requesting interferon gamma release tests and the results of this test in patients who requested it. Methods: Patients admitted to internal medicine and rheumatology outpatient clinics were retrospectively screened within the retrospective cohort study. In total, 364 patients who requested interferon gamma release testing were included in the study. Nine patients with unclear test results were excluded. Laboratory results, demographic data, reasons for requesting the interferon gamma release test, and results were evaluated. Results: The interferon gamma release test was requested by 355 patients. Of these, 266 patients (74.9%) asked for latent tuberculosis screening before treatment with biological agents and JAK inhibitors. This was followed by patients with peripheral lymphadenopathy-lung nodules, patients with unexplained elevated acute phase reactants, and patients with constitutional symptoms, respectively. Ten out of 107 patients (9.3%) had an active tuberculosis infection, while six out of ten patients (60%) had pulmonary tuberculosis, and four (40%) had extrapulmonary tuberculosis. Conclusion: The most common reason for requesting the interferon gamma release test in internal medicine and rheumatology clinics was screening for latent tuberculosis before treatment with biologic agents and JAK inhibitors. In internal medicine, it has been observed that this test can also be requested by patients with constitutional symptoms, unexplained elevated acute phase reactants, and a preliminary diagnosis of tuberculosis in order to rule out or strengthen the preliminary diagnosis.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74206858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Approximately 75% of the patients are diagnosed at an advanced stage, and high-grade serous-type ovarian cancer is detected in most of these patients. The final pathology result in our case was high-grade serous ovarian carcinoma. Our patient, 39 years old, applied to our emergency department with complaints of inability to urinate for three days and new onset abdominal pain. We were consulted because of detection of an 11 cm solid mass and globe vesicle in the pelvic region detected on the computed tomography (CT) taken in the emergency department. The patient's initial hemoglobin value was 11.2 g/dL and the beta-human chorionic gonadotropin (ß-HCG) value was negative. During the follow-up, the patient’s hemoglobin values were 9.2 and then decreased to 8.6, 8.1, and 6.5 g/dL after which hypotensive shock developed in the patient. The patient was taken for an emergency laparotomy. Intra-operatively, 1500 mL of intra-abdominal hemorrhagic fluid and diffuse tumor fragments were observed. In the right adnexal area, approximately 11 cm of ruptured tumor tissue, which may originate from the ovary or uterus, was observed. It was observed that the Douglas pouch and uterine, internal iliac , and some parts of the external iliac arteries were extensively invaded by the tumor and active bleeding occurred. Total Abdominal Hysterectomy + Bilateral Salpingo-Oopherectomy (TAH+BSO) was performed on the patient. Additional surgical intervention could not be performed because the patient had extensive vascular tumor invasion, heavy bleeding, and was in hypotensive shock. Six anti-bleeding sponges were placed on intra-abdominal bleeding areas. In addition, packing was applied to the patient by placing four sterile compresses and soft drains inside the abdomen. Tranexamic acid was administered to the patient, and six units of red blood cell suspension and four units of fresh frozen plasma were transfused.
