    Determination of Volume Overload by Bioelectrical Impedance Analysis and NT-ProBNP in Diabetic Pre-dialysis Patients

    Acta Endo (Buc) 2016 12(1): 19-25 doi: 10.4183/aeb.2016.19

    Abstract
    Introduction. Diabetic chronic kidney disease has more fatal clinical progresses and this situation can be related to volume overload, which is seen more commonly in diabetic chronic kidney disease patients than in non-diabetic chronic kidney disease patients. Therefore, we examined the effect of diabetes mellitus on volume overload in newly diagnosed stage 5 chronic kidney disease patients whose volume overloads were not showing signs of improvement from renal replacement therapy. Method. One hundred and five patients (46 diabetic, 59 non-diabetic) with end-stage chronic kidney disease, who had glomerular filtration rate (GFR) under 15 mL/min for at least three months were enrolled in this prospective study. We determined the body volume overload and configuration using a bioimpedance device. NT-proBNP levels were recorded. Results. There was a statistically significant difference between diabetic and non-diabetic groups according to overhydration (OH, p=0.003), extracellular water (ECW, p=0.045), intracellular water (ICW, p<0.001) and OH/ECW (p=0.003). In addition, there was a statistically significant difference between groups in terms of N-terminal Pro-brain Natriuretic Peptide (NT-proBNP levels, p=0.008). Discussion. We compared diabetic and nondiabetic end-stage chronic kidney disease patients who were not in renal replacement therapy yet. We found more volume overload and extracellular fluid volume in the diabetic group.

    A Different Perspective of Elevated Lactate in Pediatric Patients with Diabetic Ketoacidosis

    Acta Endo (Buc) 2020 16(1): 32-35 doi: 10.4183/aeb.2020.32

    Abstract
    Objective. This study aims to determine the frequency and prognostic significance of lactic acidosis in children with diabetic ketoacidosis (DKA) admitted to the pediatric intensive care unit. Methods. The study was carried out retrospectively by examining the patients admitted to the pediatric intensive care unit for the treatment of DKA. The ages of the patients ranged from 2 to 18 years. The patients with the following parameters were enrolled in the study: serum blood glucose>200 mg/dL, ketonuria presence, venous blood gas pH ≤7.1, bicarbonate <15. Results. A total of 56 patients were included in the study with a mean age of 111.07 ± 51.13 months. The recovery time from DKA was 16.05 ± 6.25 h in the group with low lactate level and it was 13.57 ± 8.34 h in the group with high lactate level with no statistically significant difference. There was a negative correlation between lactate levels and the recovery time from DKA. Conclusion. Lactic acidosis is common in DKA, and unlike other conditions, such as sepsis, it is not always a finding of poor prognosis that predicts the severity of the disease or mortality. We think that high lactate may even protect against possible brain edema-cerebral damage in DKA.

    Adult Nesidioblastosis, Diagnostic Value of the Selective Arterial Calcium Stimulation Test and Perfusion Computed Tomography. A Case Report

    Acta Endo (Buc) 2015 11(1): 85-92 doi: 10.4183/aeb.2015.85

    Abstract
    Endogenous hyperinsulinemia was found in a 38-yearold female patient with recurrent neuroglycopenic symptoms (the glucose level was 25 mg/dL, insulin 43.9 μ/mL, C-peptide 5.54 ng/mL). No lesion was found on imaging tests including enhanced computed tomography (CT) methods performed with a preliminary diagnosis of insulinoma. A suspicious hyperperfusion was present in the pancreatic tail on the perfusion CT examination performed after obtaining approval. The selective arterial calcium stimulation test (SACST) result was consistent with a diffuse disease in the body and tail. The patient underwent partial (75%) pancreatectomy and is now followed up as a diabetes patient on intensive insulin treatment at the postoperative 38th month. The most common cause of endogenous hyperglycemia in hypoglycemia patients is insulinoma. The noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS) is rarely seen in the adult age group. Although invasive, SACST seems to be the most suitable test to differentiate diffuse or multiple disease from insulinoma and to guide the surgery when advanced radiological imaging methods are inadequate to detect the presence of insulinoma. Regarding perfusion CT, it would be more appropriate to wait for comparative data to be put forward in a more consistent manner. When no response can be obtained to medical treatment in NIPHS, partial/total pancreatectomy is the most appropriate treatment option as it enables recovery from the hypoglycemic episodes despite leading to a significant condition like diabetes.

    Hypercalcemic Crisis in Systemic Lupus Erythematosus

    Acta Endo (Buc) 2018 14(1): 102-104 doi: 10.4183/aeb.2018.102

    Abstract
    Severe hypercalcemia is often caused by primary hyperparathyroidism (PHP), which is not commonly seen in patients with systemic lupus erythematosus (SLE). In this case report a 77 years old woman with a history of SLE develops mild hypercalcemia secondary to unrecognized PHP that leads to a hypercalcemic crisis with a prolonged recovery. Therefore, early diagnostic evaluation of persistent hypercalcemia in patients with SLE is important for detection and appropriate treatment of PHP to avoid a hypercalcemic crisis and associated prolonged morbidity.

    Is Repeat FNAB Necessary For Thyroid Nodules with ND / UNS Cytology?

    Acta Endo (Buc) 2022 18(1): 127-133 doi: 10.4183/aeb.2022.127

    Abstract
    Context/Objective. The standard approach is to perform repeat FNAB (rFNAB) in thyroid nodules with nondiagnostic (ND) / insufficient (UNS) cytology. However, due to the nature of these nodules, recurrent FNABs may also be insufficient. Therefore, by comparing the clinicalradiological- pathological parameters of nodules with a definite diagnosis of excision, we questioned the possibility of patient management without rFNAB. Methods. Clinical-radiological parameters of 275 nodules belonging to 264 patients in the ND/UNS aspiration group with definite pathological diagnosis after surgery were determined. Under the guidance of these parameters, those with and without rFNAB were compared. Results. The incidence of malignancy was found to be significantly higher in nodules without rFNAB compared to nodules with rFNAB (p = 0.036). In addition, the incidence of malignancy in BC-1 nodules without rFNAB was significantly higher than in nodules with rFNAB result also BC-1 (p = 0.009). In all cases, nodule size smaller than 10 mm and border irregularity were found to be statistically significant for malignancy (p <0.020, p <0.002). When looking at the distribution of rFNAB results, a significant correlation was observed with female gender, solid component, hypoechogenicity, border irregularity and halo loss around the nodule in patients with BC-4,5,6 cytology results (respectively, 0.005 / 0.031 / 0.001 / 0.012 / 0.004). Conclusion. rFNAB did not show the expected effect in ND / UNS nodules. We recommend direct surgical excision without rFNAB for nodules with border irregularity, solid structure, halo loss and hypoechogenicity, which should be considered more important in female patients.

    Development of Clinical Risk Assessment Tool for Osteoporosis (Osteoriskapp) Using a Syndromic Approach

    Acta Endo (Buc) 2018 14(1): 133-141 doi: 10.4183/aeb.2018.133

    Abstract
    Context. DEXA is recommended for osteoporosis screening. However, the rate of screening with DEXA is very low. Therefore, methods that can be used more easily and cost effectively are needed. Objective. The objective of this study is to develop a clinical risk assessment tool of osteoporosis (OSTEORISKAPP) by using syndromic approach. Design. A methodological study was performed. Subjects and Methods. Three hundred and fiftysix participants who are above 50 years old are participants of study and take history and physical examination. Positive likelihood ratio (LR), pre and post test probability, is calculated. A logistic regression analysis and a ROC analysis are made with the model constructed by those criteria. Results. Eighteen different clinical risk indices are diagnosed. According to LR, 4 of these criteria are minimally effective, 11 of them are weakly effective and 3 of them are medium effective criteria According to results of logistic regression analysis, back pain, waist pain, and usage of cortisone for more than 3 months, vertebra tenderness in physical examination, having dorsal kyphosis and being obese are turned out to be statistically significant in 89.9% confidence interval. AUC is found to be 0.948 and diagnostic test is found to have perfect distinction ability. Conclusion. Syndromic diagnostic criteria that will be used for osteoporosis screening of population and that is cost effective, no need to refer, practical, reliable and has tried to be developed.

    Warthin-like Tumor of the Thyroid - A Rare Variant of Papillary Thyroid Cancer: Report of Two Cases

    Acta Endo (Buc) 2014 10(1): 150-154 doi: 10.4183/aeb.2014.150

    Abstract
    Background. Warthin-like tumor of the thyroid (WALTT) is a very rare variant of papillary thyroid cancer.We want to draw attention to this rare condition by reporting two cases. Patient reports. Patient 1 was a 24 year-old woman presented with 14×12 mm solid nodule on the left lobe of the thyroid gland. Fine needle aspiration biopsy of the nodule was reported as suspicious for papillary thyroid carcinoma. Patient 2 was a 40 year-old woman who had multinodular thyroid gland with a 31×26 mm major nodule on the left lobe. On fine neddle aspiration, cytologic findings were consistent with papillary thyroid carcinoma. Both underwent total thyroidectomy and histological examination of the cases revealed Warthin-like tumor of the thyroid. Summary and conclusion. We report two patients with WALTT. This rare variant of papillary thyroid cancinoma has four main histologic criteria: papillary architecture, oxyphilic cytoplasmic changes, papillary nuclear features and dense lymphoid infiltrate. WALTT can be distinguished from other aggressive variants with these distinct histological features. Since variants show different clinical behaviour, classification of these might be helpful to predict patient prognosis.

    Possible association between hormonal status and adipose tissue culture characteristics in obese and non-obese sujects

    Acta Endo (Buc) 2008 4(2): 151-160 doi: 10.4183/aeb.2008.151

    Abstract
    The aim of this study is to investigate the possible association between hormonal status and adipose tissue characteristics in obese and non-obese subjects. Fourteen obese and 15 nonobese premenopausal female patients were enrolled in the study. Stromal vascular cells were isolated and cultured using modified procedures described by Entenmann and Hauner. In the non-obese group, omental SVCs seeded at a density of 4.12?1.1x103/cm2 in 25-cm2 in culture flasks for measuring cell proliferation and subcutaneus SVCs seeded at a density of 2.05?0.76x103/cm2 in 25-cm2 at culture flasks. In the obese group, omental SVCs seeded at a density of 6.11?1.98x103/cm2 in 25-cm2 at culture flasks for measuring cell proliferation and subcutaneous SVCs seeded at a density of 2.94?0.75x103/cm2 in 25-cm2 in culture flasks. Mean GPDH activity levels were significantly higher in SVCs from the omentum in obese compared to those from the omentum in nonobese (651.9?65.7 vs 405.1?60.1 mU/mg protein). However, GPDH activities were similar in SVCs from the subcutaneous SVCs in obese subjects, compared to those from the subcutaneous SVCs in non-obese subjects (303.5?63.2 vs 367.4?73.7 mU/mg protein). In obese group, omental SVCs number was positively correlated with plasma estradiol (E2) (r=0.604, p=0.017), and fasting insulin levels (r=0.843, p=0.01). It was negatively correlated with plasma progesterone (r=-0.793, p=0.006), prolactin (r=-0.655, p=0.008) and free T3 (FT3) levels(r=-0.630, p=0.01). These findings suggest that there are differences in adipose tissue proliferation capacity and metabolic activity between obese and non-obese subjects. In obese group, the number of omental stromal vascular cells was positively correlated with plasma estradiol and insulin levels.

    Determination of Mandibular Bone Changes in Patients with Primary Hypothyroidism Treated with Levothyroxine Sodium

    Acta Endo (Buc) 2023 19(2): 201-207 doi: 10.4183/aeb.2023.201

    Abstract
    Background. This study aimed to assess fractal dimension (FD) and the radiomorphometric indexes on the digital panoramic radiography (DPR) of patient with primary hypothyroidism receiving levothyroxine sodium replacement therapy. Methods. A total of 115 subjects were included in this cross sectional retrospective study. According to the results of the thyroid function tests, the subjects were divided into two groups as primary hypothyroidism (levothyroxine sodium replacement therapy given), (n = 57) and the healthy control group (n = 58). The fractal dimension (FD), panoramic mandibular index (PMI), mandibular cortical width (MCW), gonial index (GI) and mandibular cortical index (MCI) values of all patients were calculated on DPRs. The statistical analysis of all data was performed with SPSS version 22. Results. The distributions of age and gender in the primary hypothroidism group were similar to control group (p = 0.19 and p = 0.62, respectively). The two groups did not differ statistically significantly in terms of FD, PMI, MCW, GI, and MCI. Conclusion. We determined that mandibular cortical and trabecular bone structure did not significantly differ between healthy individuals and patients receiving drug replacement theraphy due to hypothyroidism, but our results should be further supported with the investigation of clinical parameters.
