An evaluation of the effect of the use of platelet-rich fibrin on tonsillectomy results.

PURPOSE: The aim of this study was to investigate the effect of liquid platelet-rich fibrin (PRF) during tonsillectomy on postoperative results. PATIENTS AND METHODS: This study included 41 patients who underwent tonsillectomy between April 2022 and January 2023. Liquid-PRF at a dose of 1 â€‹cc was injected to three different points of one of the tonsil fossae, selected at random intraoperatively. The same amount of physiological saline was injected to the symmetrical points on the opposite tonsil fossa using the same size injector. Pain, wound healing, and bleeding were evaluated on postoperative days 1, 7, and 14. The data of both sides were compared statistically as the study and control sides. RESULTS: The pain scores were the highest for both sides on postoperative day 1, and gradually decreased in the following days, with no significant difference determined between the sides (p â€‹> â€‹0.05). Wound healing rates in the 1st week and 2 â€‹nd â€‹week were similar for both sides. Although there were more patients who have 100 â€‹% epithelization in the PRF group on the postoperative day 14, the difference between the groups was not statistically significant (p â€‹> â€‹0.05). CONCLUSIONS: The injection of PRF following tonsillectomy had no significant effect on postoperative pain, wound healing, or bleeding.

Elevating precision: A thorough investigation of multiparametric prostate MRI for prolonged insights into early continence prediction after robot-assisted laparoscopic prostatectomy.

BACKGROUND: While radical prostatectomy stands out as one of the most effective curative treatments for prostate cancer, it does come with annoying side effects, such as urinary incontinence (UI). We aimed to investigate the predictability of UI using MRI measurements, along with clinical and disease-related variables. METHODS: We included 191 patients who underwent robot-assisted laparoscopic radical prostatectomy between July 2020 and October 2022 in the study. Preoperative MRIs of the patients are re-evaluated by an experienced uroradiologist, and membranous urethral length (MUL), urethra wall thickness, levator ani thickness, outer levator distance, Lee's apex shape, intravesical prostate protrusion length, prostate apex depth, and pubic height measurements were made. Additionally, retrospective data on patients' age, BMI, PSA, PSA density, prostate volume, IPSS, clinical stage, and nerve-sparing status were collected. Patients were categorized into two groups based on continence status in the third postoperative month: continent or incontinent. The definition of UI was accepted as the use of one or more pads per day. RESULTS: UI was observed in 38.21 % of the patients in the postoperative third month. Among MRI measurements, only MUL showed a significant relationship with UI (p < 0.001). IPSS (p = 0.004) and Clinical Stage (p < 0.001) were also significantly associated with continence status. Logistic regression analysis identified BMI (p = 0.023; CI 0.73-0.97), IPSS (p = 0.002; CI 1.03-1.17), MUL (p = 0.001; CI 0.66-0.90), and Clinical Stage (p < 0.001; CI 1.53-2.71) as significant predictors. In Multivariable Regression analysis, Clinical Stage emerged as the most powerful predictor of UI (p < 0.001). CONCLUSIONS: Except for MUL, MRI measurements may not predict postoperative UI. A combination of IPSS, clinical stage, and MUL effectively informs patients about postoperative outcomes. These findings contribute to enhancing preoperative counseling for patients undergoing radical prostatectomy.

The impact of preoperative ureteral stent duration on retrograde intrarenal surgery results: a RIRSearch group study.

A JJ stent placed before retrograde intrarenal surgery (RIRS) may ease the procedure. However, it is important to note that a prolonged duration of double J stent (DJS) placement before RIRS may increase the risk of postoperative urinary tract infection (UTI). Various publications have established this association, although the duration of the DJS before surgery is scarce. Our study investigates the relationship between the pre-stenting period and postoperative UTI and establishes a cut-off period to minimize this risk. We included a total of 500 cases with preoperative DJS prior to RIRS. The patients were divided into five groups according to their preoperative stenting duration (Group 1: 0-15 days; Group 2: 16-30 days; Group 3: 31-45 days; Group 4: 46-60 days; Group 5: >60 days). Demographic and clinical data of the patients, stone properties, operation data, perioperative and postoperative complications (including fever and UTI), hospitalization time, and stone-free rates (SFR) were compared. The groups contained 53, 124, 102, 63, and 158 patients. The demographics of the patients in each group were similar. There was no statistically significant difference between DJS duration, perioperative/postoperative complications, and SFR, except for the ureteral access sheath (UAS) insertion rate. (p = 0.001). The postoperative fever/UTI rate was the lowest in Group 1 (p = 0.046) compared to other durations. Stent duration does not impact SFR. Longer stents enhance UAS insertion success but increase postoperative infection risk. Our results suggest that RIRS should be performed within two weeks, ideally 20 days following stent insertion, to minimize postoperative infection risk.

Comparison of a coronary bypass surgery using a combination of both on-pump beating heart and cardioplegic arrest with conventional coronary bypass surgery using cardioplegic arrest on-pump.

Objective: Antegrade cardioplegia may cause maldistribution in patients with multivessel coronary artery disease. Surgically bypassing large epicardial vessels before the cross-clamp and then administering cardioplegia from both the aortic root and the anastomosed grafts significantly prevent maldistribution and provide better cardiac protection. Methods: This study included 80 patients, all older than 70 years with an ejection fraction between 25 and 35%. Patients were equally divided into two groups. Distal anastomoses to some of large epicardial coronary arteries were performed before the cross-clamp was placed. Grafted veins were attached to multi-perfusion set ports. Then, cross-clamping was performed, and the multi-perfusion set was disconnected from the aortic cannula and attached to the cardioplegia route. Antegrade cardioplegia was administered to both the aortic root and saphenous vein grafts. After all distal anastomoses were completed, the cross-clamp was removed, and the multi-perfusion set was connected to the aortic cannula again. Conventional coronary bypass techniques were used in group 2 patients. Results: Inotropic agents were administered in 12 patients in group 1 and 29 patients in group 2 (p < 0.001). The average troponin I value in coronary sinus blood was 1.05 ± 0.8 ng/mL in group 1 and 3.12 ± 0.7 ng/mL in group 2 (p < 0.001). The average lactate value in coronary sinus blood was 1.15 ± 0.55 mmol/L in group 1 and 3.7 ± 2.4 mmol/L in group 2 (p < 0.001). Six patients died in the early postoperative period in group 2 (p = 0.028). Conclusion: The current technique considerably reduces cross-clamping time and allows better distribution of the cardioplegic solution, preserving myocardium. Reduced coronary sinus lactate and troponin I levels also indicate better myocardial protection.

Still Using Only ChatGPT? The Comparison of Five Different Artificial Intelligence Chatbots' Answers to the Most Common Questions About Kidney Stones.

Objective: To evaluate and compare the quality and comprehensibility of answers produced by five distinct artificial intelligence (AI) chatbots-GPT-4, Claude, Mistral, Google PaLM, and Grok-in response to the most frequently searched questions about kidney stones (KS). Materials and Methods: Google Trends facilitated the identification of pertinent terms related to KS. Each AI chatbot was provided with a unique sequence of 25 commonly searched phrases as input. The responses were assessed using DISCERN, the Patient Education Materials Assessment Tool for Printable Materials (PEMAT-P), the Flesch-Kincaid Grade Level (FKGL), and the Flesch-Kincaid Reading Ease (FKRE) criteria. Results: The three most frequently searched terms were "stone in kidney," "kidney stone pain," and "kidney pain." Nepal, India, and Trinidad and Tobago were the countries that performed the most searches in KS. None of the AI chatbots attained the requisite level of comprehensibility. Grok demonstrated the highest FKRE (55.6 ± 7.1) and lowest FKGL (10.0 ± 1.1) ratings (p = 0.001), whereas Claude outperformed the other chatbots in its DISCERN scores (47.6 ± 1.2) (p = 0.001). PEMAT-P understandability was the lowest in GPT-4 (53.2 ± 2.0), and actionability was the highest in Claude (61.8 ± 3.5) (p = 0.001). Conclusion: GPT-4 had the most complex language structure of the five chatbots, making it the most difficult to read and comprehend, whereas Grok was the simplest. Claude had the best KS text quality. Chatbot technology can improve healthcare material and make it easier to grasp.

A Novel and Simple Method for a Differentiation of Alcohol Types.

BACKGROUND: Alcohol poisoning is a significant global problem that has become an epidemic. The determination of the alcohol type is hereby essential as it may affect the course of the treatment; however, there is no routine laboratory diagnostic method for alcohol types other than for ethanol. In this study, we aimed to define a simple method for alcohol type differentiation by utilizing a combination of breathalyzer and spectrophotometrically measured serum ethanol results. METHODS: A breathalyzer and spectrophotometry were used to measure four different types of alcohol: ethanol, isopropanol, methanol, and ethylene glycol. To conduct serum alcohol analysis, four serum pools were created, each containing a different type of alcohol. The pools were analyzed using the spectrophotometric method with an enzymatic ethanol test kit. An experiment was conducted to measure the different types of alcohol using impreg-nated cotton and a balloon, simulating a breathalyzer test. An algorithm was created based on the measurements. RESULTS: Based on the results, the substance consumed could be methanol or isopropanol if the breathalyzer test indicates a positive reading and if the blood ethanol measurement is negative. If both the breathalyzer and the blood measurements are negative, the substance in question may be ethylene glycol. CONCLUSIONS: This simple method may determine methanol or isopropanol intake. This straightforward and innovative approach could assist healthcare professionals in different fields with diagnosing alcohol intoxication and, more precisely, help reducing related morbidity and mortality.

Injection, hematoma, abscess, systemic inflammatory response syndrome, stairway to hell: Case report.

RATIONALE: Intramuscular injections are routine outpatient procedure performed at healthcare institutions worldwide. In the current literature, there have been very few reports of gluteal superior artery injuries due to incorrect injection techniques. However, no one has ever reported a healthy middle-aged man with systemic inflammatory response syndrome with possible injection-related bleeding from the gluteus superior artery, followed by a hematoma, and then a deep abscess after 3 weeks of not receiving treatment. PATIENT CONCERNS: A 40-year-old man presented with pain in his buttock, a fever of 40°, and a lump after a dorso-gluteal injection. (November, 2022) The patient was diagnosed with systemic inflammatory response syndrome due to a deep abscess related to a hematoma caused by a possible superior gluteal artery branch injury. DIAGNOSES: He was admitted to our institution with a lump, pain in his buttock, and a fever of 40° after a dorso-gluteal injection. The patient had diffuse swelling and tenderness in the upper-posterior aspect of the gluteal region. Systemic examination revealed yellow sclera and icteric skin appearance. Blood tests showed low hemoglobin levels and increased pre-sepsis parameters (procalcitonin and indirect bilirubin). Pelvic MRI and ultrasonography revealed a gluteal abscess. INTERVENTIONS: The patient was transferred to the operating theater, where a curved incision was made behind the trochanter. The gluteus maximus was bluntly dissected, and abscess fluid was drained from the muscle. Continuous bleeding was detected, suggesting iatrogenic superior gluteal artery branch injury at the time of the injection. OUTCOME: After drainage and antibiotic treatment, the patient's parameters normalized within 5 days, and the patient was discharged. The patient's weekly follow-up examinations were normal, and he was able to walk without a limp. A postoperative visit to the outpatient clinic 2 months after the operation and a telephone call 17 months later showed that the patient was completely healthy and able to work. LESSONS: The dorso-gluteal technique has potential risks, including possible injury to the sciatic nerve and superior gluteal artery and irritation of the subcutaneous adipose tissue. This article aims to highlight the potential risks of a particular technique and advocate the use of the ventrogluteal technique instead of the traditional dorso-gluteal technique.

Follicular Thyroid Carcinoma with Unusual Mandible Metastasis.

Follicular thyroid cancer is the second-most common type of thyroid cancer after papillary thyroid cancer. Metastases to the mandible and maxillofacial region are rare. Our study presents a 55-year-old patient who underwent total thyroidectomy for follicular thyroid cancer and subsequent radioactive iodine therapy. Sixteen years after diagnosis, elevated thyroglobulin levels suggested disease recurrence. Using advanced imaging techniques - Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography scan, bone scintigraphy, and posttreatment I-131 scan-an unexpected metastatic site was identified: the left mandibular condyle. A biopsy confirmed the presence of metastatic follicular thyroid cancer.

The Efficacy and Safety of Retrograde Intrarenal Surgery in Elderly Patients: A Propensity Score Matching Study by the RIRSearch Group.

INTRODUCTION: The aim of the study was to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) in elderly patients by comparing them with propensity score-matched age-groups. METHODS: Patients who underwent RIRS to treat upper urinary tract stone disease at seven centers were included in the study and were divided into four groups. The age intervals of the patients in group 1, group 2, group 3, and group 4 were 18-29 years old, 30-49 years old, 50-64 years old, and over 65 years old, respectively. Propensity score matching analysis was used to homogenize the groups in terms of demographic and clinical properties. Operative results, preoperative complications, perioperative complications, postoperative complications, duration of hospitalization time, and stone-free status were compared between groups. RESULTS: A total of 1,017 patients were included in the study. There were 69 (9.9%) patients in group 1, 324 (46.5%) in group 2, 217 (31.1%) in group 3, and 87 (12.5%) in group 4 after propensity score matching. The operation time and postoperative complication rates were significantly different among groups, whereas the hospitalization time, perioperative complication rates, and stone-free status were similar. The operation time was significantly higher in patients over 65 years old (p = 0.001). The postoperative complication rates were significantly higher in group 1 with Clavien I-II complication predominance (p = 0.003). CONCLUSION: The efficacy and safety of RIRS did not change with aging, and RIRS was an effective option for the treatment of upper urinary system stones in elderly patients.

Evaluation of information accuracy and clarity: ChatGPT responses to the most frequently asked questions about premature ejaculation.

Background: Premature ejaculation (PE) is the most prevalent sexual dysfunction in men, and like many diseases and conditions, patients use Internet sources like ChatGPT, which is a popular artificial intelligence-based language model, for queries about this andrological disorder. Aim: The objective of this research was to evaluate the quality, readability, and understanding of texts produced by ChatGPT in response to frequently requested inquiries on PE. Methods: In this study we used Google Trends to identify the most frequently searched phrases related to PE. Subsequently, the discovered keywords were methodically entered into ChatGPT, and the resulting replies were assessed for quality using the Ensuring Quality Information for Patients (EQIP) program. The produced texts were assessed for readability using the Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), and DISCERN metrics. Outcomes: This investigation has identified substantial concerns about the quality of texts produced by ChatGPT, highlighting severe problems with reading and understanding. Results: The mean EQIP score for the texts was determined to be 45.93 ± 4.34, while the FRES was 15.8 ± 8.73. Additionally, the FKGL score was computed to be 15.68 ± 1.67 and the DISCERN score was 38.1 ± 3.78. The comparatively low average EQIP and DISCERN scores suggest that improvements are required to increase the quality and dependability of the presented information. In addition, the FKGL scores indicate a significant degree of linguistic intricacy, requiring a level of knowledge comparable to about 14 to 15 years of formal schooling in order to understand. The texts about treatment, which are the most frequently searched items, are more difficult to understand compared to other texts about other categories. Clinical Implications: The results of this research suggest that compared to texts on other topics the PE texts produced by ChatGPT exhibit a higher degree of complexity, which exceeds the recommended reading threshold for effective health communication. Currently, ChatGPT is cannot be considered a substitute for comprehensive medical consultations. Strengths and Limitations: This study is to our knowledge the first reported research investigating the quality and comprehensibility of information generated by ChatGPT in relation to frequently requested queries about PE. The main limitation is that the investigation included only the first 25 popular keywords in English. Conclusion: ChatGPT is incapable of replacing the need for thorough medical consultations.
