    The antioxidant capacity of the methanolic extract and the fatty acid composition of C. kotschyi var. persica were investigated. Six different chemical methods were used to determine the antioxidant capacity. The fatty acid composition was analyzed using gas chromatography. The IC50 value of the extract was determined as 37.09 μg/ml (in the DPPH assay). In the β-carotene/linoleic acid system, the extract exhibited 65.22% inhibition against linoleic acid oxidation. The amount of total phenolic content and total antioxidant capacity were detected as 36.52 mg gallic acid equivalent (GAE)/g and 74.93 mg ascorbic acid equivalent (AE)/g, respectively. The major fatty acid in the composition of C. kotschyi var. persica was found to be C 18:3 ω3 (α-linolenic acid) by GC analysis. The results presented here indicate that C. kotschyi var. persica possess strong antioxidant properties. Therefore, the species can be used as a natural additive in food, cosmetic and pharmaceutical industries.La capacidad antioxidante de extractos metanólicos y composición de ácidos grasos de C. kotschyi var. pérsica fueron investigados.

    © 2020 Wiley Periodicals LLC. The side effects of synthetic antioxidants make it necessary to find a natural alternative. Therefore, the current study investigates the potential of T. spruneriana as a new alternative in terms of natural bioactive components. In this context, antioxidant activity, enzyme inhibition, and phenolic compounds of different extracts including ethanol, methanol, ethyl acetate, and aqueous were identified. The results show that the ethyl acetate (113.59 ± 2.73 mg GAE/g) has the highest phenolic content, but ethanol extract has the highest scavenging activity for DPPH and TAC. The ethanol extract showed stronger inhibition on cholinesterase and α-amylase compared to other extracts. Besides, 12 bioactive compounds were characterized in T. spruneriana extracts by HPLC-DAD. Our findings support that T. spruneriana could be considered as a new source of active phytochemicals, as well as provide remarkable data on biological activities of some main enzymes playing role in the healing of hyperpigmentation, Alzheimer, and diabetes. Practical applications: This study reports the total content, types and amounts of bioactive compounds and potential beneficial bioactivities of the different extracts of T. spruneriana. Trigonella is abundant in nature and spread over a wide geographical area, and is used in making cheese, pastries, spices, and sausages in different countries, as well as for antidiabetic purposes. Trigonella leaves are a good source of bioactive compounds that contain compounds like quercetin, catechin, cinnamic acid, and coumaric acid, along with it have also a high content of soluble fibers and is suggested for body weight control. Apart from being the first study conducted to point out the potential of T. spruneriana as being a natural food additive, this study also demonstrated its medicinal importance by revealing the anti-hyperpigmentation, antidiabetic, neuroprotective, and antioxidant properties of T. spruneriana.info:eu-repo/semantics/publishedVersio

    <p>Abstract</p> <p>Background</p> <p>The quadriceps femoris muscle ruptures usually occur in the middle-aged population. We present a 4-year-old patient with partial rupture of the quadriceps femoris muscle. To our knowledge, this is the youngest patient reported with a quadriceps femoris muscle rupture.</p> <p>Case Presentation</p> <p>A 4-year-old girl admitted to our clinic with left knee pain and limitation in knee movements. Her father reported that she felt pain while jumping on sofa. There was no direct trauma to thigh or knee. We located a palpable soft tissue swelling at distal anterolateral side of thigh. The history revealed that 10 days ago the patient was treated for upper tract respiratory infection with intramuscular Clindamycin for 7 days. When we consulted the patient with her previous doctor and nurse, we learnt that multiple daily injections might be injected to same side of left thigh. MRI showed a partial tear of vastus lateralis muscle matching with the injection sites. The patient treated with long leg half-casting for three weeks. Clinical examination and knee flexion had good results with conservative treatment.</p> <p>Conclusions</p> <p>Multiple intramuscular injections may contribute to damage muscles and make prone to tears with muscle contractions. Doctors and nurses must be cautious to inject from different parts of both thighs.</p

    Objectives: We aimed to evaluate the effect of American Society of Anesthesiology (ASA) classification scoring and age on complications and surgical outcomes during and after percutaneous nephrolithotomy (PCNL) operation. Material and methods: The records of 263 patients, above the age of 18 years, that underwent PCNL surgery between October 2014 and May 2017 were evaluated retrospectively. The patients were divided into three groups based on their ASA risk scores (ASA 1, 2, 3) and into two groups based on their age (younger and older than 65 years). Postoperative complications were assessed according to the ASA groups and age and according to the Clavien classification system. Results: The number of patients in the ASA 1, 2, and 3 groups were 97 (36.8%), 131 (49.8%) and 35 (13.3%), respectively. Four patients in ASA4 were not included in the study. There was no significant difference in ASA 1, 2, 3 groups in terms of changes in Hgb values, mean duration of operation, and mean hospital stay. When ASA1 was compared to ASA3 and ASA2 was compared to ASA3, there was no significant difference in the incidence of all complication rates. There were 159 (60.4%) patients in the young group and 104 (39.5%) patients in the elderly group. Postoperative PCNL complications of these 2 groups were compared according to Clavien classification system and no significant difference was found in incidence of complications. Conclusions: We believe that PCNL operation can be performed effectively and safely in both ASA3 patients and patients above the age of 65 years

    Purpose. The aim of this study was to present the computed tomography (CT) findings of bezoars that cause obstruction in the small bowel and to emphasize that some CT findings can be considered specific to some bezoar types. Materials and Methods. The records of 39 patients who underwent preoperative abdominal CT and subsequent operation with a diagnosis of intestinal obstruction due to bezoars were retrospectively analyzed. Results. In total, 56 bezoars were surgically removed from 39 patients. Bezoars were most commonly located in the jejunum (n=26/56, 46.4%). Sixteen (41.0%) patients had multiple bezoar locations in the gastrointestinal tract. Common CT findings in all patients were a mottled gas pattern and a focal ovoid or round intraluminal mass with regular margins and a heterogeneous internal structure. Furthermore, some CT findings were determined to be specific to bezoars caused by persimmons. Conclusions. Preoperative CT is valuable in patients admitted with signs of intestinal obstruction in geographic regions with a high bezoar prevalence. We believe that the correct diagnosis of bezoars and the identification of their number and location provide a great advantage for all physicians and surgeons. In addition, some types of bezoars have unique CT findings, and we believe that these findings may help to establish a diagnosis

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Get PDF
    Objectives: This study aims to report our experience regarding patients who were surgically treated due to hypothenar hammer syndrome and review the related literature. Patients and methods: The study included 11 hands of eight patients (5 males, 3 females; mean age 48 years; range 29 to 60 years) who underwent surgery due to hypothenar hammer syndrome between September 2004 and March 2013. Mean follow-up period was 50 months (range 3-103 months). The time of symptom onset, occupational history, and detailed physical examination findings were recorded. Surgery was performed under sedation and axillary anesthesia. Distal segment of the forearm, all thrombosed segments of the Guyon and superficial arch were removed. Reconstruction of the ulnar artery and the superficial arch was performed using vein grafts obtained from the forearm. Results: While all patients' dominant hand was affected, both hands were affected in three patients. All patients complained of pain and color change in one finger or multiple fingers. While minimal amputation and debridement of fingertip pulp was performed in two patients, all other patients recovered uneventfully. Patency of the ulnar artery was uneventful at follow-up in five of the eight patients, whereas three patients were performed revision surgery for a new vein graft. Most patient complaints resolved during the follow-up period. Conclusion: Hypothenar hammer syndrome is a disease of the upper extremities that should be considered in patients with digital ischemia, and a history of manual labor and smoking. Although this disease can be treated with conservative therapy, advance-stage patients who fail to respond to conservative treatment can be treated surgically with vein grafts

    Background. This study was conducted to compare and evaluate the effect of adding lornoxicam or nitroglycerine as adjuncts to lidocaine in intravenous regional anesthesia (IVRA). Methods. 60 patients were randomly separated into three groups, lidocaine group (group L), lidocaine + lornoxicamgroup (group LL), and lidocaine + lornoxicam + transdermal nitroglycerine group (group LL-N). Hemodynamic parameters, sensory and motor blocks onset, and recovery times were recorded. Analgesic consumption for tourniquet pain and postoperative period were recorded. Results. Sensory block onset times and motor block onset times were shorter in the LL-N and LL groups compared with L group. Sensory block recovery time and motor block recovery time were prolonged in the LL and LL-N groups compared with group L. The amount of fentanyl required for tourniquet pain was less in group LL and group LL-N when compared with group L. VAS scores of tourniquet pain were higher in group L compared with the other study groups. Postoperative VAS scores were higher for the first 4 hours in group L compared with the other study groups. Conclusion. The adjuvant drugs (lornoxicam or TNG) when added to lidocaine in IVRA were effective in improving the overall quality of anesthesia, reducing tourniquet pain, increasing tourniquet tolerance, and improving the postoperative analgesia
