Laryngomalacia is the most frequent cause of stridor in children under 1 year. The airway obstruction generates turbulent airway flow and creates the characteristic high-frequency stridor sound. In addition, the airway obstruction can cause apnea, a following drop in oxygen saturation and sleep disturbances. The symptoms of laryngomalacia are often worsened by activity, feeding, crying and lying flat on the back. The diagnosis is made with flexible laryngoscopy when the child is awake. The children are most often treated with expectation, information and guidance, observation with help with feeding and reflux treatment. Up to 20% of patients have a severe degree of laryngomalacia with apneas, which is an indication for surgical treatment. The investigators want to examine whether sleep examinations can help us deciding which child benefit from surgery, and follow-up the child again after 4-6 weeks and 1 year. The sleep examinations are carried out with polygraphy and/or polysomnography with simultaneous audio records and video monitoring and with Somnofy from VitalThings. The investigators want to use artificial intelligence and machine learning when analyzing the sleep examinations. The investigators also want to have a control group examining the sleep and breathing during night at home. In both groups the investigators want to examine the quality of life with the questionnaire ITQoL-SF47.
To evaluate the effect of using a mathematical model developed through pre- and post-surgical hemoglobins to predict the volume to aspirate in patients undergoing primary body liposuction.
The purpose of this study is to measure the short- and long-term voice outcome and outcome predictors of glottoplasty, cricothyroid approximation, thyroplasty, and chondrolaryngoplasty using a prospective non-randomized controlled trial and a multidimensional voice assessment protocol. Secondly, a laryngeal magnetic resonance imaging protocol will be developed to measure pre- and postoperative anatomical factors and compare them with the acoustic changes.
Breast-conserving surgery is the standard treatment for young breast cancer patients, while mastectomy with breast reconstruction is an alternative for those who are not eligible for Breast-conserving surgery. Several studies have compared the quality of life and patient satisfaction among individuals receiving different types of surgery (Breast-conserving surgery, mastectomy alone, or mastectomy with reconstruction). For example, Meghan R. demonstrated that patients undergoing Breast-conserving surgery experience a higher quality of life compared to those undergoing mastectomy with breast reconstruction, whereas J. Dauplat's study showed that patients who undergo mastectomy with breast reconstruction report a higher quality of life than those who undergo mastectomy alone. However, the investigators hypothesize that the advantages of a specific type of surgery over another, such as Breast-conserving surgery versus breast reconstruction, may vary among patients with different socioeconomic factors. For instance, the benefits of breast reconstruction over Breast-conserving surgery might be more pronounced in young patients who require a more socially active lifestyle. Additionally, the benefits of one type of surgery over another may also vary at different time points during post-operative follow-up. Furthermore, it is worth noting that most current studies have been conducted in Caucasian populations. In contrast to Caucasians, Asians typically have smaller breast volumes, potentially leading to more significant defects after Breast-conserving surgery and possibly poorer aesthetic outcomes. Therefore, a study focusing on Asian young breast cancer populations is necessary.
Although unprecedented advances have been made in the field of esophageal cancer in recent decades, the prognosis for patients with locally advanced esophageal squamous cell carcinoma (ESCC) remains extremely poor, accounting for 30-40% of overall survival at 5 year. In recent years, multimodal treatments have proven to be an appropriate therapeutic approach for locally advanced ESCC. Recently, immunotherapy developed rapidly. The purpose of this study was to observe the efficacy and safety of cardonilizumab combined with chemoradiotherapy in the treatment of locally advanced ESCC.
The study is a randomized, double-blind, controlled trial evaluating the efficacy of 2% lidocaine gel in reducing postoperative pain and analgesic consumption after haemorrhoidectomy. 222 patients undergoing Ferguson haemorrhoidectomy will be randomly assigned to receive either 2% lidocaine gel or a non-anaesthetic lubricant gel control. Pain scores using a visual analog scale (VAS) will be assessed at 12 and 24 hours, and 2, 3, and 7 days postoperatively. Analgesic consumption will also be measured.
in healthy patients undergoing elective surgery, after a very slow induction, using Eleveld's kinetics as a reference, after loss of consciousness (LOC) and intubation, proceed to infuse propofol until 1% burst suppression ratio is obtained. Then return to the LOC concentration. The BISindex predicted by the model and the real one will be evaluated. The evolution of spectral density frequencies over time will also be evaluated.
The research is planned as a randomized controlled experimental at Erzurum Atatürk University Health Application and Research Center. The population of the research will include patients who come to the General Surgery Gastroenterology service for laparoscopic cholecystectomy between the specified dates and who meet the criteria for inclusion in the study. In this research, 30 experimental and 30 control group patients will be included in the study in order to perform parametric tests. The data of the research were prepared by the researcher using the literature and similar studies after obtaining ethics committee approval and written permission from the institution where the research would be conducted. "FR.3- Alertness and Sedation Observer Assessment Scale (OAA/S)" and Modified Aldrete Scoring, Awake and Sedation Observer Assessment Scale and "FR.4- MAS and OAA/S Scores Time-Dependent", which includes the Patient's Vital Signs, are used to evaluate the patient's condition. Patients determined by the "Change Table" will be collected by observing them before and after surgery. In the research; In order to more easily overcome the anxiety and confusion that patients who have undergone surgical operations experience during the orientation process while waking up after the case, the patient will be given suggestions regarding the post-anesthesia waking period by testing the menthol smell in the preoperative period. When the patient hears the menthol scent applied during postoperative awakening; It is intended for the patient to remember that his surgery is over, that he needs to wake up and that the medical staff is waiting for him to wake up. In this way, it is thought that the patient's anxiety and complexity during the postoperative awakening period will be eliminated, the patient's vital signs will remain at an optimum level, and a more comfortable reanimation will occur.
Laparoscopic and minimally-invasive robotic access has transformed the delivery of urological surgery. While associated with numerous desirable outcomes including shorter post-operative stay and faster return to preoperative function, these techniques have also been associated with morbidity such as reduced renal blood flow and post-operative renal dysfunction. The mechanisms leading to these renal effects complex are multifactorial, and have not been fully elucidated. However they are likely to include direct effects from raised intra-abdominal pressure, and indirect effects secondary to carbon dioxide absorption, neuroendocrine factors and tissue damage from oxidative stress. It is well documented that pneumoperitoneum places profound stress on the cardiovascular, respiratory and gastrointestinal systems; it also places strain on the renal system. During robotic surgery, continuous pneumoperitoneum and continuous rising of intra-abdominal pressure causes transient oliguria. Moreover, kidney function, estimated by the GFR, deteriorates during elevated intra abdominal pressure (IAP), and most of the studies identified decrease in renal blood flow (RBF) and renal cortical perfusion. Studies conducted to assess the contribution of the nitric oxide (NO) system to the renal hemodynamic/function alterations during pneumoperitoneum, concluded that these adverse effects are probably related to interference with the NO system, and could be partially ameliorated by pretreatment with nitroglycerine. Mannitol is an osmotic diuretic and a renal vasodilator that promotes tubular flow, prevents intratubular cast formation, decreases postischemic cellular swelling, and might serve as a free radical scavenger. Mannitol has traditionally been administered before renal surgeries to minimize perioperative renal dysfunction according to preclinical animal studies and clinical experience with renal transplantation. However, high-level clinical data in support of this belief are not available. The aim of this study is to characterize the effects of increased intra-abdominal pressure on renal perfusion and function in cases undergoing robotic lower tract urologic surgeries, and to assess the contribution of either mannitol or nitroglycerin infusion to the renal hemodynamic/function alterations during pneumoperitoneum.
