RESUMO
BACKGROUND: Atypia of undetermined significance (AUS) is an indeterminate category in the Bethesda system for reporting thyroid cytopathology. Cytological features described as atypia are not always observed in every case, and it is difficult to determine how the small population of cells with enlarged nuclei, a few grooves, and rare elongated nuclei should be classified. Therefore, there is inter-intra observer variability considering these cell types, even though the cytological criteria are well defined. Therefore, this study aimed to establish a nuclear scoring system to help in the differential diagnosis of AUS. METHODS: Fine needle aspiration (FNA) samples that showed AUS and had surgical follow-up were included in this study. The aspirate was scored for the presence of intanuclear cytoplasmic inclusions, nuclear grooves, overlapping, enlargement, and elongation individually. The total nuclear score for each case was calculated. Statistical analysis of the association between each nuclear feature and the presence of papillary thyroid cancer (PTC) in the surgical specimens was performed. Cut-off points from the total score of these nuclear features were also calculated. RESULTS: Nuclear grooves and overlapping were more common in malignant cases (pâ¯<â¯0.001 and pâ¯=â¯0.048, respectively). A cut-off point of ≥5.5 for the total score was sensitive and specific for defining malignancy. CONCLUSION: The risk of PTC was higher in nodules with more prominent nuclear overlapping or nuclear groove in their FNA samples. In order to achieve a more confident AUS diagnosis, our scoring system can be helpful for thyroid FNA samples.

The prognostic nutritional index (PNI) is a new marker used to assess a patient's nutritional and immune status. It is calculated using serum albumin levels and total lymphocyte count. The aim of this study was to investigate the relationship between PNI and amputation in patients with diabetic foot ulcer (DFU). Patients with DFU were enrolled in this retrospective study. In our study, a total of 386 patient data, of 110 (28.5%) amputated and 276 (71.5%) non-amputated patients, were statistically analyzed. PNI values were significantly lower in the amputated patient group than in the non-amputee patient group (p < 0.001). According to the ROC analysis results, PNI was significant in the prediction of amputation at an excellent level (AUC = 0.937 (0.911-0.963), p < 0.001). The optimal cut-off point for PNI was found to be 39,005. There was classification success for this cut-off point: sensitivity was calculated as 82.7% (74.1-89) and specificity as 93.1% (89.3-95.7). In the multivariate model, the odds ratio (OR) (95% CI) was calculated as 81.8 (38.5-173.7) for PNI. The PNI was associated with an increase in amputation rate in patients with DFU. By using PNI, patients can be directed to advanced centers and have access to early and appropriate interventions.
RESUMO
Background/Aim: Diabetic foot infection (DFI) occurs frequently in patients, followed up with diabetic foot ulcers (DFU). For this reason, antibiotic treatment is often used in patients followed with DFU. Inappropriate use of antibiotics and increasing antibiotic resistance threaten public health. We aimed to investigate the microbial spectrum and antimicrobial resistance patterns isolated from diabetic foot infections in Turkey and help clinicians to choose optimal antibiotics empirically. Materials and Methods: This study was planned as a retrospective, single-center, cross-sectional study. Two hundred sixty-two patients whose causative microorganism was isolated in culture of tissue between 1 January 2021 and 31 December 2022 were included in this study. Bacterial profile and antimicrobial resistance patterns were analyzed. Results: Four hundred thirty two isolates from 262 patients isolated in culture of tissue were evaluated. Of these microorganisms, 57.60% were Gram-negative, 41.20% were Gram-positive bacteria, and 1.2% were Candida spp. The most frequently detected Gram-positive microorganism was Staphylococcus spp. Gram-negative microorganisms were Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa). Polymicrobial infections were observed in 40.5% of the patients. Methicillin-resistant Staphylococcus spp. rate was 51.3%, while extended-spectrum beta-lactamase (ESBL) resistance for E. coli was 66.7%. Conclusions: Due to increasing antibiotic resistance rates, treatment of common infections becomes more difficult. Knowledge of the microbiological profile and antibiotic resistance patterns of patients with DFIs is useful to guide empirical therapy.
RESUMO
BACKGROUND: Diabetic foot attack (DFA) is considered one of the worst manifestations of diabetic foot. It is necessary to act quickly to prevent amputation and save the patient's life. The aim of this study is to reveal the characteristic features of DFAs and be a guide to healthcare professionals to manage and refer these patients. METHODS: Sixty-five patients with DFAs were analyzed retrospectively. Demographics were collected. All patients' infectious dis-eases Society of America/International Working Group on the Diabetic Foot (IDSA/IWDGF) stages, site ischemia neuropathy, bacterial infection and depth (SINBAD) and laboratory risk indicator for necrotizing fasciitis (LRINEC) scores were calculated. According to these measurements, patients were categorized and statistical results were obtained. RESULTS: We found that patients who underwent emergency surgery due to DFA applied to an average of two hospitals before applying to our facility and the median acceptance time since the beginning of the first complaint was 9 days. All patients were IDSA/IWDGF stages three and four. Most of the patients had SINBAD scores between four and six. 60% of the patients were at high risk for necrotizing fasciitis according to the LRINEC score. 58.2% of patients had periferic arterial stenosis and the amputation rate was 69.2%. 21.3% of the patients were followed in the intensive care unit, and our patients' mortality rate was 4.2%. CONCLUSION: DFA is an emergency surgical condition that requires high clinical suspicion. If not diagnosed and treated with emergency surgery, it has a high mortality and amputation rate. High white blood cell count in patients, local and systemic signs of inflammation, presence of subcutaneous emphysema in the lower extremities on a direct X-ray radiography, and high blood sugar should be considered as warning signs for DFA. Emergency surgical intervention should be performed on these patients, and if the patient is not in a suitable center for emergency surgery, they should be rapidly referred to a center with experienced clinicians.

OBJECTIVES: This study aims to investigate the types of wounds and wound care in earthquake victims rescued from collapsed buildings after the 2023 Kahramanmaras earthquake. PATIENTS AND METHODS: Between February 8th, 2023 and March 1st, 2023, a total of 94 patients (46 males, 48 females; mean age: 40.2±15.5 years; range, 16 to 77 years) with earthquake-related wounds who were trapped under rubble were retrospectively analyzed. Data including age, sex, duration of being trapped under rubble, type and location of the wound, bacterial cultures from deep tissue, and wound care methods used were recorded. RESULTS: The mean duration of being trapped under rubble was 58±38.1 h. Wounds were most commonly located on the lower extremities, followed by the upper extremities. The most common type of wounds were abrasions, followed by necrotic wounds due to crushing. Wound and skin antiseptics, debridement and negative pressure wound therapy (NPWT) were the most common wound care methods used. CONCLUSION: Various types of injuries and wounds may occur after natural disasters. Chronic wound care is as important as the management of life-threatening acute pathologies. Preparations should be made properly for the long-term treatment of patients after disasters. Methods such as NPWT, debridement creams containing collagenase, wound and skin antiseptics, and hyperbaric oxygen therapy can provide satisfactory short-term results. A broader and more intense application of these treatments is thought to be beneficial, particularly in crush injuries.

BACKGROUND: Hospitalizations in emergency general surgery (EGS) cases in the USA have increased by 28% since 2001. The costs of these cases are estimated to increase by 45% annually until 2060, reaching 41.20 billion dollars. According to the literature, the general surgery clinic team allocates an average of 5.5 hours a day for emergency room consultations. The aim of this study is to determine the effects of consultations from the emergency room in our country on the EGS approach and to create appropriate solution proposals with the data obtained from the regional hospitals. METHODS: The source of the data in our study is the number of EGS cases presented by 10 regional hospitals at the Central Anatolia regional meetings of The Turkish Association of Trauma and Emergency Surgery between 2017 and 2020. MATLAB R2021b (The MathWorks, Inc., Natick, Massachusetts, USA) and SPSS (IBM SPSS Statistics for Windows, version 22.0, IBM Corp., Armonk, NY, USA) programs were used for data analysis and graphics creation. RESULTS AND CONCLUSIONS: The hospitalization/consultation rate was evaluated as the success of the doctors working at the emergency department in recognizing EGS cases; the average value was 20.15% across all hospitals. The surgery/emergency hospitalization rate, which shows rate of the hospitalized patients underwent surgery, is 59.17% when all centers are taken into account. The rate of surgery/admission in acute cholecystitis cases is 31.49% for all centers. It is seen that the hospitalization/consultation rate decreases with the increase in hospital workload. The rate of laparoscopic/total appendectomy is 22.78% across all centers. There is a correlation between acute appendicitis cases and EGS consultation numbers, but there is no correlation between laparoscopic appendectomy and consultation numbers. In addition, it is seen that medical follow-up is preferred in acute cholecystitis cases in centers where the consultation burden is increased; cholecystectomy is preferred at a higher rate in centers where the consultation burden is less. National EGS systems are needed and tried to be developed in order to improve the approach and outcomes of EGS patients worldwide. It is considered essential to establish a national EGS maintenance system that coordinates country resources and optimizes outcomes.

BACKGROUND: In the presence of advanced age and comorbidities, patients with gallstones may face gangrenous and perforated cholecystitis during their follow-up. In the literature, dynamic thiol/disulfide homeostasis has been shown to play an important role in detoxification, antioxidant protection, regulation of enzymatic reactions, and apoptosis and cellular signaling mechanisms. In this study, we aimed to evaluate the efficacy of IMA and thiol/disulfide homeostasis in the preoperative diagnosis of patients with cholelithiasis, acute/chronic cholecystitis, and perforated gallbladder. METHODS: Sixty-six patients that presented to the General Surgery Clinic of Ankara City Hospital for a cholecystectomy operation between February 2019 and May 2020 were included in this study. The patients were divided into three groups depending on the condition for which they were scheduled for surgery: cholelithiasis, cholecystitis, and perforated gallbladder. The demographic data, history of cholecystitis, chronic disease, white blood cell (WBC), amylase, lipase and liver function tests (AST and ALT) were recorded before the operation. Gallbladder appearance was evaluated using hepatobiliary ultrasonography. The duration of surgery, pericholecystic adhesions, hospital stay, body mass index (BMI), postoperative complications, and pathology results of specimens were recorded. In addition, thiol/disulfide and IMA values were analyzed in the blood samples taken from the patients preoperatively. RESULTS: The mean native thiol and total thiol values of the patients with an adhesion score of 0 were significantly higher than those with an adhesion score value of 1, 2 or 3. In addition, the disulfide, disulfide/native thiol, native thiol/total thiol and IMA values of the cases with an adhesion score of 2 or 3 were significantly higher than those with an adhesion score of 0. The native thiol and total thiol averages of the patients with normal cholecystectomy were higher than the others. The disulfide, native thiol/total thiol and IMA averages of those who underwent cholecystectomy due to a perforated gallbladder were also higher than the other groups. The mean preoperative WBC of the patients who underwent cholecystectomy due to a perforated gallbladder was also significantly higher than the other groups. Lastly, the native thiol and total thiol values had a statistically significant negative correlation with age, operation time, and hospital stay, and a statistically significant positive relationship with BMI. CONCLUSION: We consider that in the preoperative diagnosis of the perforated gallbladder, the evaluation of thiol/disulfide hemostasis and IMA parameters can be used as an effective and reliable method to predict intraoperative difficulties.

BACKGROUND: We aimed to compare the cytology and histopathology results of hot, cold, and warm nodules in patients who had thyroidectomy due to toxic multinodular goiter (TMNG). METHODS: Five hundred and nine thyroid nodules from 413 patients who had operation with TMNG were included in this retrospective study. The nodules were categorized as hot, cold, and warm groups. The cytology and histopathology results were compared. RESULTS: The 509 thyroid nodules were grouped as hot (n = 364 [71.5%]), cold (n = 122 [24.0%]), and warm (n = 23 [4.5%]) according to scintigraphy. Cytological evaluations of 364 hot nodules were as follows: 80 (22%) nondiagnostic (ND), 259 (71.2%) benign, 17 (3.6%) atypia of undetermined significance/follicular lesion of undetermined significance (AUS/ FLUS), 2 (0.5%) follicular neoplasm/suspicious for follicular neoplasm (FN/SFN), 2 (0.5%) suspicious for malignancy (SM), and 4 (1.1%) malignant. The cytology of 122 cold nodules were ND in 25 (20.5%), benign in 86 (70.5%), AUS/FLUS in 8 (6.6%), FN/SFN in 1 (0.8%), and finally SM in 2 (1.6%). The 23 warm nodules were determined as ND, benign, and FN/SFN in 7 (30.4%), 15 (65.2%) and 1 (4.3%), respectively. There were no differences according to cytological results between groups (P = .616). However, malignancy rate was 3.8% in hot nodules, it was found as 6.6% in cold nodules. The malignancy was detected in 4.3% of warm nodules. There were no differences in malignancy rates between groups (P = .459). CONCLUSION: We demonstrated similar malignancy rates in hot nodules when compared with cold and warm nodules.

PURPOSE: We aimed to investigate the relation between preoperative serum thyrotrophin (TSH) and clinicopathological features in patients with papillary thyroid carcinoma (PTC) and microcarcinoma (PTMC). METHODS: Patients who underwent thyroidectomy and diagnosed to have benign nodular disease or PTC/PTMC in our clinic were evaluated retrospectively. Patients with a previous history of thyroid surgery, patients using antithyroid medications or thyroid hormone and patients with tumors known to be unresponsive to TSH were excluded. RESULTS: Data of 1632 patients were analyzed. Histopathological diagnosis was benign in 969 (59.4%) and malignant in 663 (40.6%) patients. Preoperative median serum TSH was significantly higher in malignant compared to benign group (1.41 IU/dL vs. 0.98 IU/dL, p < 0.001). Malignancy risk increased gradually as going from hyperthyroidism to euthyroidism and hypothyroidism (20, 40.6, and 59.1%, respectively, p < 0.05). Serum TSH was lowest in benign nodular disease, higher in PTMC and highest in PTC (p < 0.001). This was also true when patients with positive antithyroid peroxidase/antithyroglobulin and with lymphocytic thyroiditis were excluded from the analysis (p < 0.001). Serum TSH was higher in patients with bilateral tumor, capsular invasion and lymph node metastasis (LNM) compared to patients with unilateral tumor, without capsule invasion and without LNM, respectively (p = 0.036, p = 0.002, and p = 0.001, respectively). Patients with aggressive variant PTC had higher serum TSH than nonaggressive ones (p < 0.05). CONCLUSION: Preoperative serum TSH is associated with PTMC, PTC and LNM. Serum TSH seems to be related with thyroid cancer regardless of autoimmunity. With the present study, for the first time, we showed an association between serum TSH and aggressive variants of PTC.
