ABSTRACT

BACKGROUND: The impact of lipid parameters on hearing loss has been extensively studied in the literature. However, there is currently no study investigating the prognostic factor of plasma atherogenic index in patients with sudden hearing loss. This study aimed to evaluate the relationship of plasma atherogenic index in patients with sudden hearing loss.

METHODS: Plasma atherogenic index is calculated using the logarithmic ratio of triglycerides [mg/dL] to high-density lipoprotein cholesterol ([mg/dL]) based on lipid parameters. The patients were divided into tertiles according to their plasma atherogenic index values and the role of plasma atherogenic index on prognosis was investigated among the tertiles. The difference between baseline and control audiometer values for each patient was calculated, and a linear regression analysis was used to determine its statistical significance.

RESULTS: A total of 84 sudden hearing loss patients (57 male: 68%; 27 female: 32%) were included in the study. The mean age of the study participants was 45.3 ± 14.0. There was an inverse relationship between plasma atherogenic index and difference of audiometer values. Linear regression analyses revealed odds ratio and 95% confidence intervals of 0.405 (0.123-1.331) with P=.135 for 500 Hz, 0.371 (0.071-0.990) with P=.048 for 1000 Hz, 0.319 (0.119-0.851) with P=.024 for 2000 Hz and 0.406 (0.161-0.992) with P=.049 for 4000 Hz.

CONCLUSION: To the best of our knowledge, this is the first study to demonstrate that plasma atherogenic index can serve as an indicator of a poor prognosis in the treatment of sudden hearing loss.

ABSTRACT

BACKGROUND: To compare the reliability of the House-Brackmann (HB), Facial Nerve Grading System 2.0 (FNGS 2.0), and Sunnybrook Facial Grading System (SB) which are widely used in the evaluation of peripheral facial paralysis (PFP) patients.

METHODS: Thirty-five video-recorded adult PFP patients were included in the study. The evaluators comprised 6 physicians. Evaluations were conducted twice independently, utilizing video recordings. Simultaneously, the evaluators were asked to keep time during the evaluation. For the analysis of reliability, Fleiss’ kappa coefficient was used for the HB, and the intraclass correlation coefficient (ICC) was used for the FNGS 2.0 and SB.

RESULTS: The mean evaluation time of 1 patient was found to be 1.06 ± 0.24, 1.47 ± 0.23, and 2.32 ± 0.41 minutes for the HB, FNGS 2.0, and SB, respectively. For interrater reliability, Fleiss’ kappa for the HB was 0.495 and 0.403; ICC for the FNGS 2.0 was 0.966 and 0.958; ICC for the SB was 0.960 and 0.967 for the first and second measurements, respectively. For intrarater reliability, Fleiss’ kappa for the HB was 0.391, 0.446, 0.564, 0.502, 0.626, and 0.455; ICC for the FNGS 2.0 was 0.87, 0.982, 0.966, 0.929, 0.933, and 0.948; ICC for the SB was 0.935, 0.96, 0.895, 0.941, 0.96, and 0.94 for the 6 raters, respectively.

CONCLUSION: In the present study, statistically high intra- and interrater correlations were found for the FNGS 2.0 and SB, while a moderate correlation was found for the HB. Although the HB seems to be more practical, it has been concluded that the FNGS 2.0 and SB are more reliable.

ABSTRACT

BACKGROUND/AIMS: Histones are a part of neutrophil extracellular trap molecules which were reported to have diagnostic values in some inflammatory diseases. We aimed to evaluate whether serum histone H4 can be a diagnostic and prognostic marker for ulcerative colitis.

MATERIALS AND METHODS: This case-control study included 58 ulcerative colitis patients (34 males and 24 females) and 45 healthy controls (25 males and 20 females). The Mayo clinical scoring system was used for the clinical and endoscopic features. Truelove-Witt’s method was applied to the histology activity index. The human histone H4 kit was used for the enzyme-linked immunosorbent assay of serum histone H4.

RESULTS: Serum histone H4 was significantly lower in the ulcerative colitis group compared to the control groups [268 (14-1639) vs. 598 (310-2134) ng/L, P < .001, respectively]. Among the ulcerative colitis patients, there was no correlation between serum histone H4 and disease extent, Mayo clinical scoring, Mayo endoscopic activity subscoring, histology activity index, inflammatory markers, d-dimer, and leukocyte and neutrophil counts (r < 0.20, P > .05). Histone H4 levels were not statistically significant between the patients with no medication and those taking 5-aminosalicylate and/or other agents (P > .05). The receiver operating characteristic curve analysis revealed that serum histone H4 concentrations had a 0.782 (95%CI: 0.690-0.857, P < .001) diagnostic accuracy for ulcerative colitis. The specificity and sensitivity for the cutoff level of ≤364 ng/L were 88.9% and 72.4%, respectively.

CONCLUSION: Decreased serum histone H4 values may be used as an auxiliary marker in the progression and diagnosis of ulcerative colitis. Further studies are needed to delineate this relationship between clinical and laboratory traits of ulcerative colitis and serum histone H4.

ABSTRACT

BACKGROUND/AIMS: Hepatocellular carcinoma is the main type of primary liver cancer. Macroscopic vascular invasion is usually identified during imaging, whereas microvascular invasion is usually determined by histopathological evaluation. We aim to identify the association between microvascular invasion and other markers of tumor aggressiveness and to identify the role of microvascular invasion in the prognosis of patients who were treated by liver transplantation for hepatocellular carcinoma.

MATERIALS AND METHODS: This is a single-center retrospective analysis of prospectively collected data. Patients who received liver transplantation for hepatocellular carcinoma were included in the study. Data were collected regarding sociodemographic variables, criteria of selection for liver transplantation, pretransplant alpha-fetoprotein, presence or absence of microvascular invasion, presence or absence of recurrence, overall survival, and disease-free survival. Data were analyzed using Statistical Package for the Social Sciences.

RESULTS: Sociodemographic laboratory values and radiologic tumor characteristics were found to be similar in patients with or without microvascular invasion. Our study revealed that microvascular invasion is associated with increased recurrence, decreased diseasedfree survival, and decreased overall survival, only for patients with hepatocellular carcinoma beyond Milan criteria at the time of liver transplantation.

CONCLUSION: For patients beyond Milan criteria, but not within Milan criteria, microvascular invasion plays a significant role in predicting recurrence and shorter survival after liver transplantation.

ABSTRACT

BACKGROUND/AIMS: Portal hypertension complicating liver cirrhosis is associated with vascular resistance, possibly due to overexpression of humoral vasoconstrictors, including endothelin. The study aimed to evaluate the efficacy of serum endothelin-1 levels as a noninvasive predictor of early esophageal rebleeding (within 5 days) following endoscopic treatment.

MATERIALS AND METHODS: Of the patients presented to the endoscopy unit at Mansoura University Hospital, 50 patients were chosen for this study on the basis of endoscopically proven acute esophageal variceal bleeding consequent to hepatitis C viral infection complicated by liver cirrhosis and portal hypertension. Routine laboratory parameters and serum endothelin-1 levels were assessed prior to endoscopic treatment. Patients were divided into 2 groups depending on the development of early postendoscopic rebleeding. Group A consisted of 16 patients who developed rebleeding, while group B included 34 patients who did not. Statistical analysis was performed to determine the predictors of rebleeding.

RESULTS: Multivariate logistic regression demonstrated that endothelin-1 level (P < .001) and serum albumin level (P = .04) were independent risk factors for early rebleeding. The most efficient cutoff value for endothelin-1 levels in predicting variceal rebleeding within the 5 days after endoscopic intervention was 65.29, which had an 88.2% specificity, 87.5% sensitivity, 88% accuracy, and area under the curve value of 0.89. In addition, hemoglobin, albumin, and creatinine levels were significantly different between bleeding and nonrebleeding groups (P = .03, P = .014, and P <.001, respectively), as was the duration of hospital stay (P < .001).

CONCLUSION: Serum endothelin-1 levels appear to be a reliable, practical, noninvasive predictor of early variceal rebleeding and related comorbidities such as the severity of kidney affection and duration of hospital stay.

ABSTRACT

OBJECTIVE: Although Gorlin syndrome has rich skin findings, there is limited information about their subtypes, features specific to this genodermatosis, and relationships with each other.

MATERIALS AND METHODS: The demographic characteristics as well as cutaneous and extracutaneous findings of consecutive Gorlin syndrome patients diagnosed during 23 years were evaluated retrospectively. The relationship between palmoplantar pitting and basal cell carcinoma (BCC) in this localization and the relationship between odontogenic keratocysts (OKCs) and epidermoid cysts were investigated.

RESULTS: A total of 30 patients were diagnosed with Gorlin syndrome of whom 36.7% were children. BCC was the most common finding (90%) followed by OKCs (83.3%), skeletal system anomalies (76.7%), and palmoplantar pitting (76.7%). While classical BCC (63.3%) lesions were the predominant clinical subtype among all patients, acrochordon-like or small-sized papular BCCs were seen in 45.4% of pediatric patients. Three patients, 2 of whom were children, had BCC lesions in the palmoplantar region in association with palmoplantar pitting. Epidermoid cysts presenting clinically as solitary (n = 12) or a few nodules (n = 4) without punctum, located more commonly in acral areas (n = 10) were seen in 16 (53.3%) patients of whom 7 were children. Epidermoid cysts were seen in 60% of patients with OKCs, and the relationship between epidermoid cysts and OKCs was not statistically significant (P = .15). Extracutaneous tumors such as medulloblastoma (n = 3), cardiac fibroma (n = 1), and ameloblastoma (n = 1) were also recorded.

CONCLUSION: The awareness of papular or acrochordon-like BCCs, palmoplantar BCCs, and acral epidermoid cysts without punctum may facilitate early diagnosis of Gorlin syndrome in children.

ABSTRACT

OBJECTIVE: The number of admissions for severe diabetic ketoacidosis (DKA) in children with newly diagnosed type 1 diabetes (T1D) increased during the coronavirus disease 2019 pandemic. We aimed to investigate whether there has been a change in this situation in recent years.

MATERIALS AND METHODS: All children with T1D who were diagnosed in our tertiary hospital between 2019 and 2023 were included. Plasma insulin, C-peptide, hemoglobin A1c (HbA1c), and antibodies against thyroid peroxidase, thyroglobulin, insulin, islet cell, glutamic acid decarboxylase, tissue transglutaminase IgA, and endomysium IgA were measured.

RESULTS: The frequency of moderate-severe acidosis at admission, which increased after pandemic period compared to the pre-pandemic period, returns to its previous levels over time but still shows a statistical difference compared to the pre-pandemic period (P = .012). Age, blood gas pH and HCO3 level, C-peptide, HbA1c, and length of stay of children at the time of admission were compared year by year (years 2019-2023). No statistical differences were observed (P = .509, P = .181, P = .069, P = .469, P = .346, P = .946), respectively. A significant difference was observed in venous glucose (P .001) and insulin (P = .001) according to years. Also, no significant difference was found about the degree of acidosis according to age (P = .334).

CONCLUSION: Although the frequency of DKA in children with newly-diagnosed T1D increased in the first years of the pandemic, it has been decreasing over t.

ABSTRACT

OBJECTIVE: Tobacco use is an important risk factor for more than 20 types of cancer, especially cardiovascular and respiratory diseases, and many other health problems. Cigarettes are one of the most commonly used tobacco products in the world, and they can cause both physical and mental addiction. Adolescence is known to be the highest-risk period in terms of addiction among all age groups. As a result, smoke-free campus practices have become even more important in universities. This study investigates the prevalence of smoking among Pamukkale Medical School students and their views and behaviors regarding smoke-free campus practices.

MATERIAL AND METHODS: This cross-sectional study was conducted with 548 medical students at Pamukkale Universıty Faculty of Medicine during the academic year 2021-2022, between April 1-29, 2022. A face-to-face interview was conducted. Students’ smoking status and their views about a smoke-free campus were assessed. In the questionnaire, the independent variables were socio-demographic characteristics, duration of staying in a smoke-free environment, smoking status in the place of residence, areas where smoking is most common, Fagerström nicotine dependence level, knowledge about smoke-free campus applications and campuses with the smokefree application. The Statistical Package for the Social Sciences version 21.0 package program was used to analyze the data. Descriptive statistics are presented with numbers and percentages for categorical variables, while the arithmetic mean and standard deviation are used for continuous variables. The chi-square test was used to compare categorical variables,and the Kolmogorov-Smirnov analysis was used to test the compatibility of data to normal distribution.

RESULTS: The student smoking rate increased significantly as the number of semesters increased (P = .021). The smoking rate of male students was higher than that of female students (P = .001). The smoking rate of students living with their family or relatives was lower (P = .020). Smokers (14.7%) were more likely to have heard about the introduction of smoke-free zones on campus than nonsmokers (11%) (P = .280). 81.4% of students affirmed the statement, “The number of smoke-free rooms should be increased,” and 84.3% responded, “I support the existence of smoke-free spaces.” Nonsmoking students (90.8%) are more likely to agree that smoke-free spaces should be increased than those who smoke (57.7%) (P < .001). Among the students, 17.6% of nonsmokers and 37.8% of smokers find the information about smoke-free spaces sufficient (P < .001). The rate of those who consider smoke-free space inspections to be sufficient is lower for nonsmoking students than for nonsmokers (P = .017). Nonsmokers (89.5%) support the existence of smoke-free spaces to a higher degree than smokers (71.2%) (P < .001).

CONCLUSION: One-third of Pamukkale University Faculty of Medicine students smoke, and smoking rates are higher among men and those who do not live with family or relatives. All participants strongly support the existence of smoke-free zones (84.3%), while a proportion of tobacco users (31.4%) support the implementation of a smoke-free campus. Student opinions of the smoke-free zones and the smoke-free campus application are more positive among nonsmokers than smokers.

ABSTRACT

OBJECTIVE: In this study, the effect of tocilizumab (TCZ) on lung tissue in lung ischemia-reperfusion (I/R) injury in rats was investigated.

MATERIAL AND METHODS: A total of 24 Wistar rats were divided into 4 equal groups, with 6 rats in each group: Left lung I/R was applied to I/R groups. In the I/R groups, the left lung hilum was clamped for 45 minutes, and then the clamp was removed and reperfused for 120 minutes. In the TCZ groups, 4 mg/kg and 8 mg/kg of TCZ were administered intraperitoneally to the rats 30 minutes before surgery.

RESULTS: The tumor necrosis factor-alpha mean value was not statistically significant between the groups (P = .091). Statistically significant results were observed between group I/R-TCZ (8 mg/kg) and group I/R for catalase. (P = .005). Statistically significant results were observed between group I/R-TCZ (8 mg/kg) and group I/R for malondialdehyde. (P = .009). The difference in total ischemia score between group I/R-TCZ (4 mg/kg) and group I/R-TCZ (8 mg/kg) and group I/R was statistically significant (P < .001). In terms of alveolar hemorrhage, there was a statistically significant difference between group I/R-TCZ (4 mg/kg) and group I/R-TCZ (8 mg/kg) and group I/R (P = .01 and P = .002, respectively). There was a statistically significant difference between group I/R-TCZ (8 mg/kg) and group I/R in terms of neutrophil accumulation (P = .01). In terms of interstitial edema, there was a statistically significant difference between group I/R-TCZ (4 mg/kg) and group I/R-TCZ (8 mg/kg) and group I/R (P = .006 and P = .001, respectively). In terms of pulmonary edema, there was a statistically significant difference between group I/R-TCZ (4 mg/kg) and group I/R-TCZ (8 mg/kg) and group I/R (P = .01 and P = .009, respectively).

CONCLUSION: Lung tissue may be affected by I/R injury and this damage can be reversed with the use of TCZ.
