Objective: Fear of falling (FoF) is common in patients with cognitive impairment. However, the role of sarcopenia and malnutrition, which are two important factors that cause falls, on FoF is unknown. The aim of this study was to explore the association between FoF and malnutrition and sarcopenia in older patients with dementia.

Methods: Two hundred and sixty-six dementia patients underwent comprehensive geriatric assessment. The Falls Efficacy Scale-International (FES-I) was applied to assign and classify FoF. Scores for the FES-I scale were categorized as ≥28, 20-27, or 16-19, representing high concern, moderate, and no or low concern about FoF, respectively. Mini Nutritional Assessment (MNA) scores <17, 17-23.5, or >23.5 were categorized as malnutrition, malnutrition risk, and well-nourished, respectively. Sarcopenia was defined using the SARC-F tool. SARC-F score ≥4 was categorized as sarcopenia. Serum folate, Vitamin B12, and Vitamin D deficiencies were also evaluated. The relationship between FoF groups and nutritional status, presence of sarcopenia, and micronutrient status was evaluated.

Results: The mean age was 80.83±6.61 years. The prevalence of moderate and high FoF in dementia patients was 51%. There was a significant difference in terms of cerebrovascular events, the history of falling, instrumental and basic activities of daily living (IADL and BADL), MNA, and SARC-F scores between the FoF groups (p<0.05). The association between sarcopenia and FoF persisted in multivariable analysis adjusted for MNA scores, cerebrovascular events, falls history, BADL, and IADL (OR=2.67, 95% CI: 1.50-4.50), but there was no significant association between malnutrition/micronutrient deficiencies and FoF (p>0.05).

Conclusion: Sarcopenia is associated with the severity of FoF, but malnutrition or micronutrient deficiencies are not associated with the severity of FoF in older patients with dementia.

Objective: Telogen effluvium (TE) is a type of alopecia that is frequently seen in women. Among factors resulting in hair loss, many reasons such as endocrine diseases, nutrition disorders, stress, anemia, low ferritin levels, vitamin B12 deficiency, and thyroid diseases are found. A digital phototrichogram is one of the non-invasive methods of diagnosis in the evaluation of alopecia. In this study, it was aimed to compare biochemical parameters of female patients with diffuse hair loss with phototrichogram findings.

Methods: 108 female patients with diffuse hair loss were included in the study. Patients were divided into two groups: acute and chronic TE, and a hair pull test was applied. Total blood count, blood biochemistry, iron, iron binding capacity, ferritin, thyroid stimulating hormone (TSH), sT3, sT4, folic acid, and vitamin B12 levels were examined. The telogen/anagen ratios and hair densities of patients were determined with a phototrichogram.

Results: The serum biochemical parameters (aspartate aminotransferase, alanine aminotransferase, urea, creatinine), TSH, sT3, sT4, and folic acid levels of patients were within normal limits. Telogen ratio, anagen ratio, hair density, number of shed hairs, family history, blood ferritin, TSH, and vitamin B12 levels were found to be similar between groups having acute and chronic TE. In our study, while mean anagen and telogen ratios with trichoscan were similar to literature data, no statistically significant correlation was determined between patients' ages and examined trichoscan findings (p>0.05). The hair pull test positivity of patients with chronic TE was higher compared to patients with acute TE (p<0.05). In patients with positive hair pull tests, the telogen ratio and hair density were found to be higher. In the group with <40 ng/mL ferritin level, the mean telogen ratio was detected to be significantly higher than the mean anagen ratio (p<0.05). No significant correlation was determined between vitamin B12 and TSH levels in patients and phototrichogram findings (p>0.05).

Conclusion: The findings of this study showed that ferritin has an important role in diffuse hair loss, and the phototrichogram method is an auxiliary method for the physician in the diagnosis of TE.

Objective: The rate of cardiovascular disease is increasing in developed countries progressively with estimates predicting 22 million by 2030. Based on these cardiovascular events lies atherosclerosis, a condition intricately linked to chronic inflammatory processes. Among fundamental clinical biomarkers, C-reactive protein (CRP) stands out as a backbone of inflammatory activity. Notably, the excessive production of CRP, often linked with obesity, plays a pivotal role in the dysregulation of triglyceride apo B-100 fractional catabolism, thus emerging as a significant cardiovascular risk factor. Apart from atherosclerotic processes, the interplay between high CRP levels and impaired fasting glucose (IFG) is also gaining recognition as a messenger of disrupted glucose metabolism, potentially ushering in the onset of a prediabetic state.

Methods: Our retrospective analysis scrutinized the biochemical data - namely low-density lipoprotein cholesterol (LDL-C), triglycerides, fasting blood sugar, and CRP levels-of 3500 patients from an internal medicine outpatient clinic seen from August 2006 to May 2007. Our objective was to dissect the correlations among these parameters. Exclusion criteria were omitting individuals with acute or chronic inflammation, known inflammatory diseases, diagnosed diabetes, coronary artery disease, lipid metabolism disorders, those on lipid-lowering agents, and anyone outside the age bracket of 18-65 years. This study was conducted in strict adherence to the ethical principles outlined in the Declaration of Helsinki.

Results: As a result of our study, the ratio of CRP levels above 0.8 was significantly higher in patients with IFG according to the World Health Organization criteria (6.1-6.9 mmol/L or 109-124 mg/dL) than in individuals with normal fasting glucose (70-108 mg/dL). (19.7%, 17.2%, respectively) (p<0.001). In addition, the ratio of CRP levels above 0.8 was also higher in patients with triglyceride levels between 151 and 199 mg/dL) and over 500 mg/dL. (23.2%, 24.1%, respectively) (p<0.012). However, the relationship between CRP levels and LDL-C total cholesterol was not statistically significant (p>0.05).

Conclusion: This retrospective study suggests the imperative for a proactive approach in the clinical evaluation of patients exhibiting elevated CRP, especially in the context of preemptive management of prediabetes. In light of these findings, we think that elevated CRP may be a warning sign for prediabetic status and may be useful in early diagnosis.

Objective: We always confirm the diagnosis of syndesmotic injury with a Hook test for all ankle fractures and fixed if necessary. Then, we noticed a discrepancy between preoperative radiology and the Hook test. Moreover, we want to report the reliability of syndesmotic fixation decisions with Hook test and preoperative radiology.

Methods: A total of 37 surgically treated patients with isolated Weber type C ankle fractures were included in the study. In all patients, the syndesmosis joint was injured in preoperative computed tomography and X-ray imaging. However, only patients with (+) Hook tests had undergone a syndesmosis fixation. Patients were divided into two groups: Group A: Hook tests (+) and Group B: Hook test (-). Also, the groups were compared according to clinical outcomes with the Visual Analog Scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS), and foot and ankle disability index (FADI) scores.

Results: The mean participant age was 39 (19-80) years, and the mean follow-up period was 47.27 (22-68) months. Groups A and B consisted of 17 (45.9%) and 20 (54.1%) patients, respectively. The mean VAS, AOFAS, and FADI scores were 17.7±14.3, 90.32±8.06, and 92.9±6.88, respectively. "Excellent" and "good" results were found in 34 (%91.8) patients according to AOFAS nad FADI. The malreduction rate was 8.1% in all patients, 5% in group A, and 11.8% in group B. No statistically significant differences in final functional scores were found between groups A and B.

Conclusion: Hook test is reliable and adequate for evaluating the stability and quality of syndesmosis reduction. Weber type C lateral malleolar fractures in the decision of syndesmosis fixation; although syndesmosis injury is diagnosed in preoperative radiology, we recommend that the diagnosis be confirmed with the Hook test.

Objective: We aimed to study myocardial functions of infants appropriate and large for gestational age (IDM-AGA, IDM-LGA) of diabetic mothers (IDM) and AGA and LGA infants of non-diabetic mothers comparatively.

Methods: Newborns were assessed between 24 and 72 h. M-Mode, pulsed wave, and tissue Doppler echocardiography were performed.

Results: A negative correlation was found between shortening fraction and maternal weight at delivery in the LGA group (p=0.009, r=-0.58). E/Early diastolic (E') ratio and deceleration time were increased in IDM-AGA than AGA group (p=0.02, p=0.02). There was a negative correlation between maternal blood glucose and E/A ratio (p=0.015 r=-0.63), a positive correlation between maternal blood glucose and mitral A, late diastolic (A') wave in IDM-AGA (p=0.014 r=0.63, p=0.016 r=0.62). Maternal weight gain during pregnancy was in correlation with measured and tei index in IDM-AGA group (p=0.008 r=0.72). Maternal age, pre-pregnancy weight, and weight at delivery and mitral E were higher in IDM-LGA group than IDM-AGA (p=0.03, p=0.01, p=0.003, p=0.012).

Conclusion: We found that maternal weight has a negative effect on myocardial function in LGA newborns. Diastolic functions were found impaired in IDM-AGA infants and in infants of mothers with high blood glucose. Maternal weight gain during pregnancy has a negative effect on myocardial functions.

Objective: This study aimed to determine the factors that increase nosocomial infections (NIs) in pediatric patients with traumatic brain injury (TBI) and the effects on both treatment cost and length of hospital stay.

Methods: We performed a case-control study on patients admitted to the pediatric intensive care unit (PICU) with (n=66) or without (n=120) TBI between 2012 and 2014. The risk factors, length of stay, and costs of NIs were determined.

Results: Data for 186 patients were analyzed. One hundred and twenty patients were controls (54 males vs. 66 females), while 66 were cases (27 males vs. 39 females). Seventeen out of the 186 PICU patients had NIs. About 7.6% of TBI patients had infections whereas 10% of control groups had NIs (p=0.58). The most isolated microbial agent was Acinetobacterbaumannii (four cases). Thirteen (76.5%) out of the 17 infections were catheter-related bloodstream infections. The mean expenses per PICU patient were $762, with an additional cost of $2081 for patients with nosocomial contamination.

Conclusion: The use of catheters was the most critical risk factor for NIs in our study probably underestimated the cost for several reasons. Nevertheless, the findings supported our hypothesis about the additional burden of nosocomial spread on PICU patients. This study's results should help provide evidence on cost-effectiveness or calculate the cost-benefit ratio of reducing NIs in children.

Objective: Current evaluations of pediatric food allergies are very important, many studies have shown that the frequency of food allergies is increasing in the pediatric age group. In this study, we retrospectively investigated the epidemiology and clinical features to better understand the clinical effects of food allergy, to contribute to the literature on this subject, and to evaluate the data of our country.

Methods: The epidemiological and clinical data of patients with food allergies diagnosed at the Erciyes University Pediatric Allergy Outpatient Clinic between 2014 and 2019 were analyzed. The outcomes were analyzed by a statistical analyzing program and compared with the literature.

Results: As a result of our retrospective evaluation, we found that the mean age of 854 patients who were diagnosed with food allergy was 21.2±30.7 months (min 0 months, max 16.5 years). 512 (60%) of our patients were female, and 342 (40%) were male. The most common complaint was rash at the rate of 75.2% and followed by itching 27.6%, angioedema 10.5%, bloody defecation 10.5%, wheezing 8.4%, vomiting 8.3%, diarrhea 6.7%, frequent bronchiolitis 6.6%, cough 6.2%, and shortness of breath 4.4%. It was shown that 32.2% of the patient had multiple food allergies and the highest sensitivity rates were 65.9% with egg allergies and 39.2% with milk. In the classification, it was found that 75.1% of the patients who were followed up with food allergy had IgE-mediated food allergy, and 24.9% had a non-IgE-mediated food allergy.

Conclusion: The results of this study of a 5-year cross-sectional evaluation of the patients diagnosed with food allergy and followed up in our clinic may contribute to the growing body of literature on pediatric-age food allergy.

Objective: In this study, the utility of histogram parameters derived from diffusion-weighted imaging for differentiate renal cell carcinoma (RCC) from oncocytoma was investigated.

Methods: This research tracked 126 individuals who were diagnosed with RCC and oncocytoma through histopathological analysis, using magnetic resonance imaging (MRI) assessments from 2015 to 2023. We observed various attributes of these patients, including demographic details, surgical records, pre-surgery MRI results, MRI apparent diffusion coefficient (ADC) histogram analysis, and post-surgery histopathological outcomes. Calculations of ADC measurements such as mean, minimum, and maximum in conjunction with the 5^th, 10^th, 25^th, 50^th, 75^th, 90^th, and 95^th quantile points were made. In addition, we also noted the skewness, kurtosis, and variance of these data points.

Results: The focus group for this investigation consisted of 75 male and 51 female patients. Out of these, 82 were diagnosed with RCC and 44 with oncocytoma. All ADC parameters including ADCmin, ADCmedian, ADCmean, and ADCmax, including the 5^th, 10^th, 25^th, 50^th, 75^th, 90^th, and 95^th quantile divisions among the oncocytoma cohort were observed to be higher than the corresponding ones in the RCC group. A statistically meaningful difference was discovered between the minimum ADC value along with the 5^th ranking of ADC measurements (p<0.001), in addition to mean of ADC (p=0.050), and the 10^th (p=0.002) and 25^th (p=0.015) quantiles of ADC data. When considering the region below the curve (AUC) in ROC analysis, the value of ADCmin was recorded as 0.739, with a sensitivity of 75.0%, and specificity of 68.2%.

Conclusion: To distinguish oncocytoma from RCC, it may be useful to conduct a whole-tumor histogram and textural analysis of ADC values.

Objective: Mammary Paget's disease (MPD) is a rare presentation type of breast cancer. The aim of this study was to evaluate the clinicopathological and imaging features affecting the invasive component, loco-regional recurrence, prognosis, and survival of MPD.

Methods: Patients who had undergone surgery due to MPD in a 10-year period were included. Parameters including mammography and magnetic resonance imaging (MRI) findings, tumor stage, molecular subtype, axillary involvement, presence of invasive carcinoma, loco-regional recurrence, overall survival (OS), and disease-free survival (DFS) were recorded and statistically analyzed. P<0.05 was determined as statistically significant.

Results: The study group consisted of 49 women with a mean age of 67.05±14.43 (range: 23-90) years. There was a significant association between the presence of invasive carcinoma and a mass lesion in the MRI (p=0.002). The frequency of sentinel lymph node (SLN) metastasis was significantly higher in patients with multicentric tumors (p=0.029; p<0.05). Locoregional recurrence and distant metastasis were significantly more frequent in patients with axillary involvement (p=0.0336; p<0.05). The mean DFS was 115.02±7.28 months, while the mean OS was 119.29±6.57 months.

Conclusion: The presence of a mass lesion on MRI was determined to be significant in recognizing invasive carcinoma in MPD. The rate of SLN metastasis was higher in patients with multicentric tumors than in patients with unifocal tumors. Axillary involvement was associated with impaired DFS.
