Hypothyroidism and subclinical hypothyroidism are associated with fatty pancreas (Non-Alcoholic Fatty Pancreas Disease).

OBJECTIVES: Increasing visceral fat deposition with raised prevalence of obesity and metabolic syndrome is associated with many adverse conditions, especially cardiovascular diseases and diabetes. Although there are many studies that investigate hepatic steatosis in hypothyroidism and subclinical hypothyroidism, to the best of our knowledge, there is no study investigating its relationship with pancreatic steatosis. In the present study, the purpose was to investigate this relationship. METHODS: Physical and biochemical characteristics of 30 hypothyroid, 30 subclinical hypothyroid, and 30 euthyroid volunteers were recorded in this cross-sectional study. Liver and pancreatic steatosis were evaluated with ultrasonography. RESULTS: It was found that pancreatic steatosis was increased in hypothyroid and subclinical groups when compared to the control group, and hepatic steatosis was increased in the subclinical group when compared to the control group (steatosis; p = 0.002, p = 0.004, p = 0.001, p = 0.002, p = 0.002, p = 0.004). Pancreatic steatosis was positively correlated with age, hepatic steatosis, height, weight, BMI, waist circumference, hip circumference, hemoglobin, Insulin, alanine aminotransferase, Triglyceride, Creatinine, and gamma-glutamyltransferase and was negatively correlated with total cholesterol, high-density lipoproteins. CONCLUSIONS: The prevalence of pancreatic steatosis was found to be increased in hypothyroidism and subclinical hypothyroidism when compared with the euthyroid control group.

The Importance of DHEA-S Levels in Cushing's Syndrome; Is There a Cut-off Value in the Differential Diagnosis?

The purpose of this study was to determine possible cut-off levels of basal DHEA-S percentile rank in the differential diagnosis of patients with Cushing's syndrome (CS) with ACTH levels in the gray zone and normal DHEA-S levels. In this retrospective study including 623 pathologically confirmed CS, the DHEA-S percentile rank was calculated in 389 patients with DHEA-S levels within reference interval. The patients were classified as group 1 (n=265 Cushing's disease; CD), group 2 (n=104 adrenal CS) and group 3 (n=20 ectopic ACTH syndrome).ROC-curve analyses were used to calculate the optimal cut-off level of DHEA-S percentile rank in the reference interval in the differential diagnosis of CS, and the effectiveness of this cut-off level in the identification of the accurate etiology of CS was assessed in patients who were in gray zone according to their ACTH levels. The DHEA-S percentile rank in the reference interval were significantly lower in group 2 compared to the other two groups (p<0.001), while group 1 and group 3 had similar levels. The optimal cut-off level of DHEA-S percentile rank in the reference interval providing differential diagnosis between group 1 and group 2 was calculated as 19.5th percentile (80.8% sensitivity, 81.5% specificity) and the level demonstrated the accurate etiology in 100% of CD and 76% of adrenal CS patients who were in the gray zone. This study showed that the cut-off value of DHEA-S level less than 20% of the reference interval could be used for differential diagnosis of CD and adrenal CS with high sensitivity and specificity, and it should be taken into the initial evaluation.

Can Serum ACE Level Be Used as a Prognostic Indicator in COVID-19?

BACKGROUND: SARS-COV-2 virus that causes COVID-19 binds to the host cell with angiotensin converting enzyme-2 causing acute respiratory distress syndrome (ARDS) and severe mortality and morbidity. There are studies in the literature conducted on the importance of serum angiotensin converting enzyme (ACE) and ACE-2 enzymes in ARDS pathogenesis. Serum ACE levels are higher in children and adolescents than in adults, and COVID-19 has a milder progression. All these reasons suggest that there may be a relationship between serum ACE levels and COVID-19 prognosis. METHODS: The serum ACE levels were determined at the time of hospitalization due to COVID-19 diagnosis in this single-centered, prospective study. According to discharge status, patients were divided into three groups as "Discharge with Healing", "Intensive Care Need" and "Mortality", and the effect of serum ACE levels on disease prognosis was investigated. RESULTS: The present study comprised a total of 103 patients, of whom 42.7% (n = 44) were female, and 57.3% (n = 59) were male. The mean age was 59.48 ± 16.47; 91.3% (n = 94) of them were discharged with healing, 5.8% (n = 6) needed intensive care, and 2.9% (n = 3) resulted in mortality. No differences were detected in terms of serum ACE levels between the groups. CONCLUSIONS: No relationships were detected between serum ACE levels at the time of hospitalization and COVID-19 prognosis.

Relation of glycated hemoglobin and vitamin D deficiency with erectile dysfunction in patients with type 2 diabetes mellitus.

Erectile dysfunction (ED) is seen very often in the men with type 2 diabetes mellitus (DM). Due to the ability of vitamin D to reduce endothelial damage and oxidative stress, its role in preventing cardiovascular risk has been demonstrated in some studies. Since ED and cardiovascular disease have common pathogenic mechanisms, many studies have evaluated a possible relationship between vitamin D deficiency and ED. Total 120 patients with type 2 diabetes mellitus were evaluated in this study. Vitamin D and HbA1c values were statistically compared according to International Index of Erectile Dysfunction (IIEF-5) scores. 23.3% of 120 patients had mild, 38.3% had mild to moderate, 21.7% had moderate and 16.7% had severe ED. There was statistically difference in vitamin D levels of the patients according to IIEF-5 scores. Also, significant difference was found in HbA1c levels between the patients with severe ED and other groups. Cut-off point for vitamin D and HbA1c were determined according to IIEF-5 score in patients who were divided in to two groups (14.41 and 11.1). A statistically significant correlation was found between both cut-off points and IIEF-5 scores. Our study shows that patients with ED have a vitamin D deficiency and a poor glycemic control.

Visfatin Levels May be an Early Marker of Atherosclerosis in Patients with Acromegaly.

The purpose of the study was to compare serum visfatin levels between patients with acromegaly and healthy controls and to evaluate the relationships between visfatin levels and epicardial fat thickness (EFT), carotid intima media thickness (cIMT), and ankle brachial index (ABI). We conducted a cross-sectional case-control study of 54 patients with acromegaly (37 females and 17 males) and 34 healthy controls (22 females and 12 males). Serum visfatin was measured by ELISA. Acromegalic and control participants and those with active or controlled acromegaly were compared with respect to their serum visfatin, clinical and metabolic parameters, EFT, cIMT, and ABI. Linear correlation was used to identify associations between these parameters and visfatin in all participants. Serum visfatin and glycated hemoglobin (HbA1c) were higher in the acromegaly group than in the control group (p<0.001 and p=0.007, respectively). There was no difference in visfatin between the active and controlled acromegaly groups, but HbA1c was higher in the active than the controlled acromegaly group (p<0.04). EFT, cIMT, and ABI were similar between the acromegaly and control groups and between the active and controlled acromegaly groups. Serum visfatin positively correlated with HbA1c, growth hormone (GH), and insulin-like growth factor-1 (IGF-1)/upper limit of normal ratio (r=0.245, p=0.024; r=0.259, p=0.017; and r=0.282, p=0.009, respectively). This study has revealed that a high visfatin level is associated with glycemic dysregulation and higher levels of GH and IGF-1 in acromegalic patients.

Dermatologic manifestations of acromegaly: A case in point and a focused review.

Acromegaly is a systemic syndrome caused by overproduction of growth hormone. Cutaneous, endocrine, cardiovascular, skeletal, and respiratory systems are affected. Cutaneous changes in acromegaly relate to overexpression of growth hormone and insulin-like growth factor 1 on skin cells and adnexa. Dermal glycosaminoglycan accumulation and edema cause skin distention that is most prominent in the face, hands, and feet. Oily skin with large pores, hypertrichosis, and excessive sweating are common features. Pigmented skin tags, acanthosis nigricans, and psoriasis are also encountered. Cutaneous manifestations of acromegaly are various and prominent, and are an important clue for the early diagnosis and treatment of this high-morbidity disorder.

Effects of mesenchymal stem cells and VEGF on liver regeneration following major resection.

PURPOSE: The study aims to determine the effects of mesenchymal stem cell (MSC) therapy and a combination therapy of MSCs transfected with vascular endothelial growth factor (VEGF) for liver regeneration after major resection. METHODS: Thirty-eight rats were divided into four groups: group 1: control (sham operation); group 2: control (70 % hepatic resection); group 3: 70 % hepatic resection + systemically transplanted MSCs; and group 4: 70 % hepatic resection + systemically transplanted MSCs transfected with the VEGF gene. MSCs were injected via the portal vein route in study groups 3 and 4. Expression levels of VEGF, fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), epidermal growth factor (EGF), transforming growth factor (TGF), hepatocyte growth factor (HGF), and augmenter of liver regeneration (ALR) were analyzed in the remnant liver tissue. We investigated the levels of angiogenic factors, VEGF-receptor, angiopoietin-1 (Angpt1) and Angpt2. Biochemical parameters of liver function in blood samples were measured and a histologic assessment of the livers was performed. The postoperative liver weight and volume of each rat were measured 14 days after surgery. RESULTS: The expression levels of all measured growth factors were significantly increased in groups 3 and 4 compared to the control groups. The levels of Angpt1 and Angpt2 correlated with levels of VEGF and thus were also significantly higher in the study groups. There were significant differences between the estimated liver weights and volumes of group 4 and the resected controls in group 2. With the exception of portal inflammation, levels of all histological parameters were observed to be higher in MSC-treated groups when compared with the resected controls in group 2. CONCLUSIONS: Transplanted stem cells and MSCs transfected with VEGF significantly accelerated many parameters of the healing process following major hepatic resection. After the injection of MSCs and VEGF-transfected MSCs into the portal vein following liver resection, they were engrafted in the liver. They increased bile duct and liver hepatocyte proliferation, and secreted many growth factors including HGF, TGFß, VEGF, PDGF, EGF, and FGF via paracrine effects. These effects support liver function, regeneration, and liver volume/weight.

The effect of vascular endothelial growth factor overexpression in experimental necrotizing enterocolitis.

PURPOSE: Necrotizing enterocolitis (NEC) is a serious condition, predominantly observed in premature infants. We used an experimental NEC model to investigate the effects of vascular endothelial growth factor (VEGF) cloned into a plasmid. MATERIALS AND METHODS: Twenty-four newborn Wistar albino rats were randomized equally into three groups as follows: control, NEC and NEC+VEGF. NEC was induced by hyperosmolar enteral formula feeding, exposure to hypoxia/reoxygenation and cold stress. In the NEC+VEGF group, VEGF (1 µg) incorporated into plasmid (2 µg) was administered subcutaneously once daily for a total of 3 days starting on the first day of the NEC procedure. All rats were sacrificed on the 4th day of life, and the specimens were harvested for histopathological and biochemical examinations [including tissue oxidative stress (malondialdehyde and nitric oxide), inflammation (myeloperoxidase, interleukin-6 and tumor necrosis factor alpha) and apoptosis (caspase-3 activity) parameters]. RESULTS: In the NEC+VEGF group, tissue malondialdehyde, nitric oxide, interleukin-6, tumor necrosis factor alpha levels and caspase-3 activity were significantly decreased. In addition, the myeloperoxidase level was increased compared to that of the NEC group (p < 0.05). Histopathologically, VEGF overexpression enhanced angiogenesis, alleviated villous atrophy and tissue edema (p < 0.05). CONCLUSION: VEGF overexpression with plasmids seems to be a promising approach in the management of NEC.

Expert opinion on screening, diagnosis and management of diabetic peripheral neuropathy: a multidisciplinary approach.

The proposed expert opinion aimed to address the current knowledge on conceptual, clinical, and therapeutic aspects of diabetic peripheral neuropathy (DPN) and to provide a guidance document to assist clinicians for the best practice in DPN care. The participating experts consider the suspicion of the disease by clinicians as a key factor in early recognition and diagnosis, emphasizing an improved awareness of the disease by the first-admission or referring physicians. The proposed "screening and diagnostic" algorithm involves the consideration of DPN in a patient with prediabetes or diabetes who presents with neuropathic symptoms and/or signs of neuropathy in the presence of DPN risk factors, with careful consideration of laboratory testing to rule out other causes of distal symmetric peripheral neuropathy and referral for a detailed neurological work-up for a confirmative test of either small or large nerve fiber dysfunction in atypical cases. Although, the first-line interventions for DPN are currently represented by optimized glycemic control (mainly for type 1 diabetes) and multifactorial intervention (mainly for type 2 diabetes), there is a need for individualized pathogenesis-directed treatment approaches for DPN. Alpha-lipoic acid (ALA) seems to be an important first-line pathogenesis-directed agent, given that it is a direct and indirect antioxidant that works with a strategy targeted directly against reactive oxygen species and indirectly in favor of endogenous antioxidant capacity for improving DPN conditions. There is still a gap in existing research in the field, necessitating well-designed, robust, multicenter clinical trials with sensitive endpoints and standardized protocols to facilitate the diagnosis of DPN via a simple and effective algorithm and to track progression of disease and treatment response. Identification of biomarkers/predictors that would allow an individualized approach from a potentially disease-modifying perspective may provide opportunities for novel treatments that would be efficacious in early stages of DPN, and may modify the natural course of the disease. This expert opinion document is expected to increase awareness among physicians about conceptual, clinical, and therapeutic aspects of DPN and to assist them in timely recognition of DPN and translating this information into their clinical practice for best practice in the management of patients with DPN.

The relationship between early atherosclerosis and endothelial dysfunction in type 1 diabetic patients as evidenced by measurement of carotid intima-media thickness and soluble CD146 levels: a cross sectional study.

BACKGROUND: Detection of early vascular changes prior to clinical manifestations of atherosclerosis, such as increased arterial carotid intima-media thickness (CIMT) and impaired endothelial function is of paramount importance for early identification of subjects at increased risk of accelerated atherosclerosis. The present study was designed to evaluate the relationship between early atherosclerosis and endothelial dysfunction in type 1 diabetic patients based on measurements of CIMT and soluble CD146 (sCD146) levels. METHODS: Thirty-seven patients with type 1 diabetes, 14 males (37.8%) and 23 females (62.2%), of mean (SD) age 26.2 (4.1) years admitted to the outpatient diabetes clinic at Okmeydani Training and Research Hospital, Istanbul, between January 2008 and December 2012, and 37 healthy controls, 16 males (43.2%) and 21 females (56.8%), of mean (SD) age 25.8 (3.1) years, selected from relatives of patients, were included. Anthropometric measures; fasting plasma glucose; and serum HbA1c, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride and creatinine concentrations were compared, as were CIMT and serum sCD146. RESULTS: Mean (SD) sCD146 levels were significantly higher in patients than in controls (314.6 (141.9) ng/ml vs. 207.8 (34.5) ng/ml, p = 0.001), but mean (SD) CIMT did not differ (0.5 (0.1) mm vs. 0.4 (0.1) mm). ROC curves for sCD146 significantly differed in differentiating type 1 diabetics from healthy controls (p = 0.0047) with a significantly higher percentage of patients than controls having sCD146 levels >260 ng/ml (21/37 (56.8%) vs. 2/37 (5.4%), p = 0.00011). CONCLUSION: Our findings emphasize that sCD146 levels may be a more sensitive marker than CIMT for earlier identification of type 1 diabetic patients at high risk for atherosclerosis.

Determinants of Awareness on Diabetes and its Complications.

INTRODUCTION: Diabetes mellitus is a chronic disease that requires continuous medical care. Raising awareness and determining the factors affecting awareness about diabetes and its complications have an important role in achieving glycemic control and preventing complications. OBJECTIVE: In this study, we aimed to determine the sociodemographic properties of participants, the status of patients' awareness, and the factors affecting awareness. We also aimed to determine the relationships between these factors and diabetes regulation. MATERIALS AND METHODS: A total of 404 patients with diabetes who had presented to Istanbul Okmeydani Research and Training Hospital, Internal Medicine and Diabetes Outpatient Clinic were included in the study. They were requested to fill in a questionnaire about diabetes awareness. Data about their survey results, sociodemographic facts, glycemic control, treatment methods, and complications were analyzed. RESULTS: 61.6% of the participants were female and 38.4% were male. Mean age was 54.5±11.4 years. 55.2% of patients were graduated from primary school and 22.8% had no education. Mean HbA1c value of the participants was 8%±1.9%. The mean score of the questionnaire, consisting of 23 questions, was 16.1±3.6. The ratio of patients who replied to 50% or more of the survey was 90.3%. The knowledge score was found to be positively correlated with education and income level, negatively correlated with age. There was no significant relationship between awareness and glycemic control (p>0.05). CONCLUSION: Most of the participants had an adequate level of awareness on diabetes and its complications. However, the study showed that better awareness was not associated with regulation of the disease. It was observed that not only raising awareness but also methods for implementing knowledge to daily life are needed.

Relationships of the neutrophil-lymphocyte and CRP-albumin ratios with the duration of hospitalization and fatality in geriatric patients with COVID-19.

OBJECTIVE: The aim of this study was to determine the associations of the neutrophil-lymphocyte ratio (NLR) and C-reactive protein (CRP)-albumin ratio (CAR) with the duration of hospital stay and fatality rate in geriatric patients with coronavirus disease 2019 (COVID-19). METHODS: Patients older than 65 years with polymerase chain reaction-positive COVID-19 were included. Neutrophil, lymphocyte, CRP, albumin, and demographic data and the duration of hospitalization were recorded. RESULTS: The mean length of stay was 15 days. NLR and CAR were significantly higher in patients who died than in those who survived. The cutoffs predictive of mortality were 4.02 (area under the curve [AUC] = 0.717) for NLR and 23 for CAR (AUC = 0.781). The fatality rate among patients who required inpatient treatment was 33%. CONCLUSION: NLR and CAR, which can be calculated inexpensively and quickly at the first admission to the hospital, are extremely useful for estimating the duration of hospitalization and risk of mortality in geriatric patients with COVID-19. Using these data, treatment can quickly be intensified when needed.

Prognostic significance of cardiac injury in COVID-19 patients with and without coronary artery disease.

OBJECTIVE: COVID-19 is a disease with high mortality, and risk factors for worse clinical outcome have not been well-defined yet. The aim of this study is to delineate the prognostic importance of presence of concomitant cardiac injury on admission in patients with COVID-19. METHODS: For this multi-center retrospective study, data of consecutive patients who were treated for COVID-19 between 20 March and 20 April 2020 were collected. Clinical characteristics, laboratory findings and outcomes data were obtained from electronic medical records. In-hospital clinical outcome was compared between patients with and without cardiac injury. RESULTS: A total of 607 hospitalized patients with COVID-19 were included in the study; the median age was 62.5 ± 14.3 years, and 334 (55%) were male. Cardiac injury was detected in 150 (24.7%) of patients included in the study. Mortality rate was higher in patients with cardiac injury (42% vs. 8%; P < 0.01). The frequency of patients who required ICU (72% vs. 19%), who developed acute kidney injury (14% vs. 1%) and acute respiratory distress syndrome (71%vs. 18%) were also higher in patients with cardiac injury. In multivariate analysis, age, coronary artery disease (CAD), elevated CRP levels, and presence of cardiac injury [odds ratio (OR) 10.58, 95% confidence interval (CI) 2.42-46.27; P < 0.001) were found to be independent predictors of mortality. In subgroup analysis, including patients free of history of CAD, presence of cardiac injury on admission also predicted mortality (OR 2.52, 95% CI 1.17-5.45; P = 0.018). CONCLUSION: Cardiac injury on admission is associated with worse clinical outcome and higher mortality risk in COVID-19 patients including patients free of previous CAD diagnosis.

Evaluation of the relationship between insulin resistance and plasma tumor necrosis factor-alpha, interleukin-6 and C-reactive protein levels in obese women.

OBJECTIVE: To investigate the relationship between insulin resistance and tumor necrosis (TNF)-alpha, interleukin (IL)-6, C-reactive protein (CRP) in obese women. BACKGROUND: Obesity and type 2 diabetes are associated with insulin resistance, the mechanisms of which remain poorly understood. MATERIALS AND METHODS: Forty obese (35.8 +/- 9.6 years) and 20 non-obese women (31.1 +/- 7.7) were recruited between June 2002 and February 2003 at the Okmeydaný Training and Research Hospital, Istanbul, Turkey. The obese group was equally divided into two according ?to their WHR (> 0.8 and 0.8). Subjects with blood pressure values higher than 140/90 mmHg, pathological findings on standard 12-lead EC3 and leukocytosis and glucose levels > 100 mg/dl were excluded. RESULTS: Plasma insulin (p < 0.0001) and fasting glucose levels (p<0.0001), and HOMA values (p < 0.0001) in the obese group were higher than in the controls. Serum triglyceride and VLDL levels were higher in the obese group (p < 0.0001 in both), whereas HDL cholesterol levels were higher in the lean control group (p < 0.0001). However, no difference was observed between two groups in terms of total cholesterol and LDL-cholesterol levels. The serum levels of both TNF-alpha, IL-6 and CRP were found elevated in the obese group (p < 0.05, p < 0.05, p < 0.01, respectively). In the subgroup analysis, only the HOMA values and TNF-alpha levels were found higher in the android obese group (p < 0.05 and p < 0.0001, respectively). CONCLUSION: Insulin resistance seems to be one of the major causes of obesity-related complications due to increased secretion of TNF-alpha, IL-6 and CRP together with android obesity (Tab. 5, Ref. 33).

Neutrophil- and Platelet- to Lymphocyte Ratio in Patients with Euthyroid Hashimoto's Thyroiditis.

BACKGROUND: Hashimoto's thyroiditis (HT) is the most prevalent autoimmune thyroid disorder. Both neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are reported to be increased in various inflammation-related diseases, but their clinical significance in HT remains unclear. OBJECTIVES: The aim of this study was to investigate the relationship between thyroid autommunity and NLR and PLR as markers of systemic inflammation in HT. METHODS: In this study, we evaluated 145 women with HT and 60 age-matched healthy controls. We compared the PLR and the NLR of HT patients with controls and the correlation between the NLR, PLR, and C-reactive protein (CRP), thyroid-stimulating hormone (TSH) and thyroid antibody titers in the patient group. Also we compared the PLR and the NLR of HT patients that received levothyroxine with those who did not receive levothyroxine RESULTS: There were no significant differences between patient and control groups in terms of overall leukocyte counts, neutrophil counts, and other laboratory tests. In the patient group lymphocyte counts were lower while the platelet counts, NLR (2.29±0.65 vs1.68±0.40), PLR (164.95±55.14 vs106.88±32.19) were higher than those of the control (p<0.001 for all comparisons). CONCLUSION: In this study we found that NLR and PLR were higher in euthyroid Hashimoto patients than in a healthy control group. NLR and PLR are likely non-specific indicators of immune disorder and their implications for HT and other conditions remain to be elucidated.

Kruppel-Like Transcription Factor-4 Gene Expression and DNA Methylation Status in Type 2 Diabetes and Diabetic Nephropathy Patients.

BACKGROUND/AIM: Diabetic nephropathy (DN) is one of the most serious microvascular complications in diabetic patients. The kruppel-like transcription factor-4 (KLF-4) affects the expression of genes involved in the pathogenesis of DN. The present study aims to identify the KLF-4 expression and DNA methylation (DNAMe) status in patients with type-2 diabetes (T2D) and DN and to reveal the contribution of the KLF-4 to the development of DN. MATERIAL AND METHODS: The cohort study was performed with blood samples from 120 individuals; T2D group (n = 40), DN group (n = 40) and control group (n = 40). The expression level of the KLF-4 gene was analyzed using the real-time polymerase chain reaction (qRT-PCR) and the methylation profile detected using the methylation-specific PCR (MS-PCR) technique. RESULTS: According to our findings, KLF-4 mRNA expression in the T2D group was 1.60 fold lower than in the control group (p = 0.001). In the DN group, the expression of KLF-4 mRNA was 2.92-fold less than that of the T2D group (p = 0.001). There was no significant alteration in the DNAMe status among the groups. CONCLUSION: Our findings showed that regardless of the DNAMe status, KLF-4 gene expression may play a role in the development of T2D and DN. This suggests that the KLF-4 gene may be the target gene in understanding the mechanism of nephropathy, which is the most important complication of diabetes, and planning nephropathy-related treatments, but the data should be supported with more studies.

Pachychoroid Pigment Epitheliopathy and Choroidal Thickness Changes in Coeliac Disease.

PURPOSE: To evaluate choroidal thickness in patients with coeliac disease (CD) using spectral domain optical coherence tomography (SD-OCT) and to compare the results to normal eyes. METHODS: Seventy patients with CD and 70 healthy controls were included in this prospective, comparative study. All participants underwent a complete ophthalmologic evaluation and SD-OCT. Subfoveal, nasal (nasal distance to fovea 500 µm, 1000 µm, and 1500 µm), and temporal (temporal distance to fovea 500 µm, 1000 µm, and 1500 µm) choroidal thickness measurements were performed using SD-OCT. RESULTS: There were no significant differences in sex, ages, and axial lengths between the groups (p=1.0, p=0.601, p=0.314, respectively). The mean choroidal thickness measurements at all predefined measurement point areas were higher in the coeliac group than in the healthy controls (p < 0.001). Of all patients with coeliac disease (70 eyes of 70 patients), 64 eyes (84.2%) had uncomplicated pachychoroid (UCP), one eye had pachychoroid pigment epitheliopathy (PPE), and five eyes in the UCP group had PPE in fellow eyes. CONCLUSION: It is probable that systemic inflammation in coeliac patients causes the enlargement of choroidal vessels and increasing choroidal thickness. PPE, which is believed to be the precursor of central serous chorioretinopathy, can be observed in coeliac patients.

The relationship between left ventricular mass and insulin resistance in obese patients.

OBJECTIVE: In this study, we investigated the relationship between left ventricular mass and insulin resistance in obese patients. METHODS: A total of 90 subjects, 66 women, and 24 men, with an age range from 24 to 56 years, were enrolled in the study. Forty-nine patients were in the obesity group whose body mass index (BMI) was >29.9kg/m(2) and 41 subjects were in the control group with a BMI <25kg/m(2). All of them were normotensive, nondiabetic, and did not have any cardiovascular disease. They were not taking any medication. Weight, height, and waist circumference were measured and BMI was calculated. Plasma glucose, insulin, serum total, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, and triglyceride levels were measured, and insulin resistance was calculated via homeostasis model of assessment-estimated insulin resistance (HOMA-IR). Subjects were examined by echocardiography and left ventricular mass (LVM) and index (LVMI) were calculated with Devereux formula. RESULTS: Insulin levels, HOMA-IR, LVM, and LVMI were significantly higher in obesity group (p<0.01). Fasting glucose, triglyceride, fasting insulin levels, and waist circumference did not correlate with LVMI. CONCLUSION: In conclusion, though findings of the present study suggest increased left ventricular hypertrophy (LVH) in obese subjects compared to controls, it appears that the increased LVM or LVH is not linked to BMI and insulin resistance in this study population.

Successful intracavitary tissue plasminogen activator treatment of gastrocnemius intramuscular hematoma in a patient following anticoagulant therapy with warfarin: case report.

Warfarin is an anticoagulant used in a variety of clinical indications and may rarely cause severe bleeding that can be life-threatening. Although intramuscular bleeding frequently occurs, secondary to trauma, it can be induced in cases with bleeding tendency. Hematoma is often treated with conventional methods. However, surgical decompression can also be applied. In this article, we report a case of gastrocnemius intramuscular hematoma, which was successfully treated with intracavitary tissue plasminogen activator that was recently used in the treatment of abdominal and pelvic abscess.

The relationship between glycated hemoglobin and blood glucose levels of 75 and 100 gram oral glucose tolerance test during gestational diabetes diagnosis.

OBJECTIVE: The diagnosis of gestational diabetes mellitus (GDM) is an important issue in terms of prevention of maternal and fetal complications. In our study we aimed to evaluate the relation of HbA1c and blood glucose levels of 75 and 50-100 gram oral glucose tolerance test (OGTT) in pregnant patients who were screened for GDM. MATERIALS AND METHODS: The parameters of 913 pregnant women screened for GDM are evaluated retrospectively. The two steps screening with 50-100 gram OGTT were used in 576 patients. The remaining 337 patients were screened with 75 gram OGTT. RESULTS: The HbA1c levels of patients having high blood glucose (≥153 mg/dl) levels at 2(nd) hour in 75 gram OGTT were significantly higher than patients having normal blood glucose levels at 2(nd) hour of 75 gram OGTT (P=0.038). Correlation analyses showed no significant relation between any blood glucose level of 100 gram OGTT and HbA1c level. Whereas in 75 gram OGTT 1(st) and 2(nd) hour blood glucose levels were found to have a significant relation with A1c levels (P=0.001, P=0.001 respectively). CONCLUSION: HbA1c may be used as an important tool in the diagnosis of GDM. But due to the variation of HbA1c in pregnant women and there is not an absolute cut-off level for A1c, it may be more reliable to evaluate HbA1c level together with the blood glucose levels in OGTT.
