Objectives: The role of hematologic, inflammatory and biochemical parameters as biomarkers, their role in identifying risky patients in the early stage and their role in prognosis in COVID-19 Coronavirus disease 2019 (COVID-19) were investigated.

Methods: The study included patients who were hospitalized and followed up with a prediagnosis of COVID-19 in the first wave in our country at the University of Health Sciences, Sisli Hamidiye Etfal Training and Research Hospital Demographic and clinical characteristics as well as complete blood count, C reactive protein (CRP), procalcitonin (PCT), fibrinogen (FIB), ferritin, albumin (ALB), lactate dehydrogenase (LDH) levels on admission, third, seventh and 14th days were analyzed. Patients were grouped and compared according to the occurrence of death during hospital follow-up. Variables considered significant on mortality were analyzed with univariate and multivariate logistic regression models.

Results: The study was conducted with 485 patients, 273 (56.3%) males and 212 (43.72%) females. The mean age of the patients was 58±16.2 years, and 71% were in the mild-moderate and 29% in the severe-critical disease group. Disease severity, the need for intensive care unit (ICU) follow-up, and the development of death were positively correlated with age, comorbidity, neutrophil (NE), leukocyte, neutrophil-lymphocyte ratio (NLR), PCT, CRP, ferritin, LDH values, and negatively correlated with lymphocyte (LE), ALB and hemoglobin (HGB) values. In multivariate analysis, elevated PCT at hospital admission (OR: 6.96 [1.63;39.65]), LDH ≥ 352U/L (OR: 4.35 [1.23;16.61]), LE<0.810 × 109/L (OR: 3.0 [1.16;7.85]) and advanced age (OR: 1.08 [1.03;1.14]) were independently associated with in-hospital death. In hemogram and acute phase reactant monitoring, PCT, CRP and LDH were the most valuable markers for predicting death, respectively (third-day AUC: 0.90;0.83;0.83 and seventh-day AUC: 0.95;0.90;0.89, respectively).

Conclusion: In our study, leukocytes, lymphocytes, NLR, CRP, PCT, ferritin, albumin and LDH at admission were valuable in predicting poor prognosis. In addition, it was determined that increases in PCT, LDH and CRP during follow-up could be used to predict in-hospital death and to identify patients requiring close follow-up.

Objectives: Struma ovarii (SO) accounts for approximately 1% of all ovarian tumors. The objective of our study is to contribute to the treatment algorithm by presenting our clinical experience in a comprehensive case series of patients diagnosed with SO, predominantly characterized by thyroid tissue within a monodermal teratoma.

Methods: Patients aged 17 years and older who underwent surgery due to ovarian masses and were histopathologically diagnosed with SO between January 2012 and January 2022 were included in the study. The patients' files were retrospectively reviewed. Demographic data, presenting complaints, radiological findings, tumor sizes, laboratory data, surgical procedures performed, pathology reports, additional treatments, and follow-up information were recorded.

Results: The median age of total 19 patients was 41.7 (17-74) years. Among them, malignant struma ovarii was present in 3 patients. In patients with histopathologically confirmed benign struma ovarii, no additional treatment was administered after tumor enucleation. In malignant cases, in addition to unilateral salpingo-oophorectomy, total thyroidectomy, radioactive iodine (RAI) ablation, and L-Thyroxine suppression were performed. No mortality occurred during the follow-up period.

Conclusion: Although conservative treatments are considered acceptable treatment in cases of benign struma ovarii, the management of cases with malignant struma ovarii is controversial. Fertility-sparing surgery followed by postoperative adjuvant thyroidectomy and radioactive iodine ablation may be preferred for young women.

Objectives: Familial Mediterranean fever (FMF) is an autoinflammatory disease more commonly observed in the Eastern Mediterranean region. Studies have shown that inflammatory processes may decrease vitamin D, vitamin B12 and folate levels, but there is no clear data on the effect of attack frequency on these levels. Our study aimed to evaluate the effect of FMF attack frequency on vitamin levels.

Methods: FMF patients aged between 4-18 years were considered as the study group, while healthy children who had vitamin levels during the same period were considered as the control group. The study group was further subgrouped according to the number of attacks. Those experiencing 2 or fewer attacks per year are classified as the attack group, while those experiencing 6 or more attacks per year are classified as the frequent attack group.

Results: A total of 494 subjects were included. The study group was composed of 333 FMF patients, 108 of them in the attack group and 225 in the frequent attack group. Control group included 161 children. The median and interquartile range (IQR: P25-75) in the frequent attack, attack, and control groups for 25(OH)D levels were 14.3 (9.57-18.9), 14.85 (10.12-21.77), and 14.95 (9.92-20.12) ng/ml, for B12 levels were 320 (238-415), 328 (250.25-439.25), and 373 (273.75-519.25) pg/ml, and for folate levels were 6 (5.13-8.12), 6.8 (5.36-8.9), and 7 (5.3-9.9) ng/ml, respectively. There is no significant difference between groups for 25(OH)D and folate (p=0.436 and p=0.25, respectively). Vitamin B12 levels are significantly lower in study group (p=0.001) but there is no difference according to attack frequency (p=0.92).

Conclusion: There is no effect of attack frequency on 25(OH)D, vitamin B12 and folate levels. The fact that vitamin B12 levels are within normal limits in patients with FMF may be explained by the adequate dietary habits of these patients.

Objectives: Chronic Limb-Threatening Ischemia (CLTI) represents a complex manifestation of peripheral artery disease distinguished by symptoms such as ischemic rest pain, non-healing ulcers on the lower limb or foot, and the development of gangrene. CLTI is associated with a high risk of limb amputation, decreased quality of life, and substantial morbidity and mortality. The Prognostic Nutritional Index (PNI), which is calculated using albumin and lymphocyte levels, reflects the immunological and nutritional status. The objective of this study was to investigate the correlation between PNI levels and mortality among patients diagnosed with CLTI who underwent endovascular therapy.

Methods: Individuals diagnosed with CLTI who received endovascular therapy below the knee in our tertiary care center were enrolled in this retrospective study. The patients were divided into two groups: survivors and non-survivors. Logistic regression analyses were performed to detect independent predictors of mortality and using Cox regression model, we assessed the relationship between PNI and mortality. Survival curves were estimated using the Kaplan-Meier method.

Results: The study comprised 113 patients diagnosed with PAD who underwent EVT. The non-survivor group (42 patients) was older (62.9±10.9 vs. 67.7±9.9, p=0.045) and had a higher prevalence of chronic renal failure (22.5% vs. 42.9%, p=0.023) and congestive heart failure (8.5% vs. 21.4%, p:0.049) than the survivor group (71 patients). The median PNI value was lower in the non-survivor group than in the survivor group (35.9±5 vs 38.2±4.4, p=0.012). Cox regression analyses showed that Low PNI was associated with increased mortality (HR=0.931, CI=0.872-0.995, p=0.035). PNI cut-off of 37.009 showed 64.3% sensitivity, 64.8% specificity, and AUC of 0.642 for predicting all-cause mortality. Kaplan-Meier analysis supported higher PNI correlating with better survival.

Conclusion: The Prognostic Nutritional Index was independently associated with mortality among individuals diagnosed with Chronic Limb-Threatening Ischemia.

Hyperthyroidism is a clinical condition that develops due to the excessive production and secretion of thyroid hormones by the thyroid gland, leading to an elevated concentration of thyroid hormones in tissues. Hyperthyroidism is characterized by low TSH and elevated T3 and/or T4, with the most common causes being Graves' disease, toxic multinodular goiter, and solitary toxic adenoma. T3 is the peripherally active form of thyroid hormone, affecting nearly each tissue and system. The most prominent aspects of hyperthyroidism are related to the cardiovascular system. The treatment of hyperthyroidism includes three options: antithyroid drugs (ATDs), radioactive iodine therapy (RAI), and surgery. Among these treatment modalities, surgery is considered as the most effective one. For patients who are candidates for surgery, preoperative preparation is required to ensure that the thyroidectomy can be performed under optimal conditions. Preoperative preparation should be a combination therapy aimed at preventing the synthesis, secretion, and peripheral effects of thyroid hormones from the thyroid gland. Medications that can be used in this treatment include thionamides, beta-blockers, iodine, corticosteroids, cholestyramine, perchlorate, lithium, and therapeutic plasma exchange. These treatment options can be combined based on the patient's condition. While it is recommended that patients be made euthyroid through preoperative antithyroid treatment to prevent the feared complication, which is the thyroid storm, the supporting evidence is limited. Preoperative treatment does not prevent against thyroid storm whether the patient is euthyroid or hyperthyroid during surgery. Whether surgery should be delayed until biochemical euthyroidism is achieved in hyperthyroid patients remains a topic of debate. Recent studies suggest that thyroidectomy can be safely performed during the hyperthyroid phase by experienced anesthesiologists and surgeons without precipitating thyroid storm or increasing intraoperative and postoperative complications. Although achieving the euthyroid state before surgery is ideal in hyperthyroid patients, it is not always possible. Factors such as allergies to medications, drug side effects, treatment-resistant disease, patient noncompliance, and the urgency of definitive treatment are critical in determining whether hyperthyroidism can be controlled preoperatively. When surgery is necessary in hyperthyroid patients without achieving euthyroidism, the patient's overall condition and comorbidities should be evaluated together by the anesthesiologist, surgeon and endocrinologist, with particular attention to stabilizing the cardiovascular system. We believe that in hyperthyroid patients who are cardiovascularly stable during the hyperthyroid phase, thyroid surgery may not need to be delayed and can be performed safely.

Objectives: There is still no clear relationship between the presence of Graves' disease (GD) and the development of papillary thyroid carcinoma. The aim of this study was to compare the clinicopathologic features of patients diagnosed with papillary thyroid carcinoma (PTC) with thyroid nodules and GD and patients with PTC with thyroid nodules but without autoimmune thyroid disease.

Methods: The study was designed in a retrospective manner and included a cohort of 239 patients with PTC who underwent total thyroidectomy. Age at diagnosis, disease stage, PTC subtypes, tumor size, radioactive iodine use, nodule ultrasonographic features, and risk of PTC recurrence were compared between patients with and without GD.

Results: Of 239 patients, 99 (41%) had GD, while 140 patients (without autoimmune thyroid disease) had only PTC. The tumor diameter was significantly smaller in the group with PTC + GD (1.45±1.28 cm vs. 1.81±1.34 cm, p<0.05). Significantly lower multifocal involvement rates were observed in the PTC + GD group compared to PTC-only group (p<0.05). The prevalence of the classic papillary thyroid carcinoma subtype was higher in patients without autoimmune thyroid disease (39% vs. 25.7%, p<0.05). Ultrasonographic features of nodules with GD and PTC do not have different characteristics from those of nodules with PTC without GD.

Conclusion: The risk of structural recurrence at the time of diagnosis appears to be similar when PTC is accompanied by GD as compared to PTC alone. Furthermore, the presence of smaller tumor sizes and less multifocality in GD-PTC coexistence may indicate a better prognosis.

Objectives: Coronary microvascular dysfunction is present in large percentage of the population, and it has been shown to have a pathological and prognostic role in many conditions. Therefore, early detection of microvascular dysfunction is important, especially in selected populations. The aim of this study was to investigate the association of galanin with coronary flow reserve (CFR) in prehypertensive individuals to determine whether it can be used as a marker to detect microvascular dysfunction.

Methods: A total of 100 participants, 50 prehypertensive and 50 normotensive were included in this prospective study. Serum galanin levels were measured and CFR was calculated by detailed transthoracic echocardiography.

Results: CFR was significantly lower in the prehypertensive group (p<0.001). Also, galanin values were numerically lower in the prehypertensive group, but the difference between the groups did not reach statistical significance (p=0.062). There was no significant correlation between CFR and galanin (r=-0.161, p=0.11).

Conclusion: Lower CFR values in prehypertensives suggest that microvascular dysfunction starts above normotensive values even if hypertension does not develop. The reason why low galanin levels were not statistically significant in prehypertensives and no correlation was found between galanin and CFR may be due to the small study population. Relationship between galanin, prehypertension and microvascular dysfunction will become clearer if large-scale population studies are carried out.

Objectives: Thyroglossal cysts (TGCs) usually present during childhood and before the age of 30, however, they can also be seen in adults, even in advanced age. Nodular thyroid disease is also common in adults. In the literature, there is an ongoing debate regarding the differences in clinical presentation, gender, and postoperative recurrence of TGC between children and adults. In this study, we aimed to process the data of adult patients who underwent surgery for TGC in our clinic, along with the data on concurrent thyroid disease and thyroid surgery.

Methods: The data of patients over 18 years old who were operated on for TGC at the General Surgery Clinic of Sisli Hamidiye Etfal Training and Research Hospital between 2018 and 2024 were retrospectively evaluated.

Results: A total of 16 patients with a mean age of 43.94±12.98 (21-67) years, were included in the study (11 F/5 M). The diagnosis of TGC was made in 12 patients (75%) by ultrasonography (USG), in 1 patient (6.25%) by computed tomography, in 1 patient (6.25%) by magnetic resonance imaging (MRI), and in 2 patients (12.5%) incidentally intraoperatively. 13 patients (81.25%) underwent the Sistrunk procedure, and 3 patients (18.75%) underwent cyst excision. Among the 16 TGC patients, papillary thyroid cancer in the cyst was detected in one patient (6.25%) preoperatively. During preoperative evaluation, nodular thyroid disease was found in 12 patients (75%). Of these, papillary thyroid cancer was detected in 3 patients (18.75%) preoperatively. Of the TGC group, 3 (18.75%) underwent thyroidectomy for thyroid malignancy, and five (31.25%) underwent additional thyroid surgery for nodular thyroid disease. The patients were followed for a mean of 22.63±18.32 months (3-67 months), and no recurrence of TGC was observed during the follow-up period.

Conclusion: In patients with TGC, thyroid diseases and the requirement for thyroidectomy due to benign or malignant thyroid disease are not uncommon. Patients with TGC should be evaluated for thyroid disease before surgical treatment. While the Sistrunk procedure is the standard surgical technique in the treatment of TGC, in adults, if the cyst terminates below the hyoid bone, total cyst excision without removing the central portion of the hyoid bone may be sufficient.

Objectives: To compare the pain perception and treatment duration in patients undergoing panretinal photocoagulation (PRP) for high-risk proliferative diabetic retinopathy (PDR) using Navilas laser versus conventional laser.

Methods: A study was conducted involving 40 patients with bilateral high-risk PDR. Each patient underwent PRP with conventional laser in one eye and Navilas laser in the other. Laser parameters, including spot size and pulse duration were standardized. Pain perception was evaluated using Verbal Rating Scale (VRS) and Visual Analogue Scale (VAS).

Results: The Navilas and conventional laser groups showed no significant differences in baseline visual acuity, lens status, intraocular pressure, cup-to-disc ratio, or cystoid macular edema. The duration of laser treatment was significantly shorter with Navilas laser group (517.3±48.78 seconds, p<0.001). Pain scores (VAS and VRS) were significantly lower in the Navilas laser group (p<0.001, p=0.002 respectively) than in conventional laser group. There was no correlation between VAS and VRS scores and laser time in both the Navilas and conventional laser groups (p>0.05).

Conclusion: Utilizing the Navilas laser for PRP in PDR patients offers advantages over conventional lasers, including reduced pain and expedited procedures. These findings contribute valuable insights for optimizing clinical decisions, potentially enhancing patient compliance and minimizing the risk of visual deterioration in diabetic retinopathy treatment.
