RESUMO
BACKGROUND: A limited number of human and animal studies suggest that a relationship exists between phthalates and obesity, although this is not supported by all research. The purpose of this study was to investigate the relationship between Body Mass Index (BMI) and the levels of phthalates in human blood and urine samples. METHODS: Sixty-four overweight or 132 obese individuals (total=196) of different ages (min-max, 17-62; mean ± SD, 42.07±11.3) and genders (F:M 97:99) enrolled in the study. BMI and waist circumference were measured to diagnose obesity. Venous blood samples were taken after overnight fasting. To compare the urine phthalates among participants, single spot urine (at least 10 mL) was collected from the subject after blood samples were taken. Urine and blood phthalate concentrations were measured using gas chromatography. RESULTS: Total blood/urinary phthalate levels significantly increased in proportion to the degree of obesity. There was a high correlation between the level of total phthalates in serum and BMI (ρ=0.697, P<0.001), and between total urinary phthalate levels and BMI (ρ=0.707, P<0.001). CONCLUSIONS: This is the first study to have shown that both blood and urinary phthalates increased in proportion to BMI. The results show a strong association between obesity and phthalates.

OBJECTIVE: To evaluate changes in calcium metabolism in patients with idiopathic benign paroxysmal positional vertigo (BPPV) on initial presentation and at the follow-up visit. SUBJECTS AND METHODS: The study comprised a total of 31 patients aged greater than 18 years who presented at the otorhinolaryngology outpatient clinic of our hospital, newly diagnosed as idiopathic BPPV based on the history compatible with BPPV and positive provocative maneuver (either Dix-Hallpike or Roll test). The first blood sample was obtained on the day of initial presentation when the patient was found to have active unilateral BPPV. After 6 months, a blood sample was again drawn in accordance with the procedure. Blood samples were analyzed for data on 25-hydroxyvitamin D (25(OH)-D), total calcium, parathormone and ionized calcium on initial presentation, and at the follow-up visit. RESULTS: The patients comprised 20 (64.5%) women and 11 (35.5%) men with a mean age of 49.78 years (range, 23-75 years). During an attack a higher prevalence of decreased serum Vitamin D is less than 20âng/ml, was determined (93.5% versus 38.7%). There were statistical differences between the Vitamin D values, parathormone, and corrected by pH ionized calcium in both periods (pâ<â0.05). CONCLUSION: A statistically significant association was determined between Vitamin D and calcium metabolism in patients with idiopathic BPPV. It can be considered that Vitamin D deficiency and decreased ionized Ca level may be a risk for BPPV, not only in patients with osteoporosis but also in all patients. Very low levels of 25(OH)-D seem to be associated with recurrence of BPPV. The recurrences might possibly be prevented with supplementary Vitamin D especially in those with recurrent idiopathic BPPV but further studies would be necessary to determine this.

BACKGROUND: Bisphenol A (BPA) has been implicated as an 'endocrine disruptor'. We aimed at exploring the association between serum BPA levels and patient characteristics, particularly the presence of diabetes mellitus, and laboratory parameters in hemodialysis patients. METHODS: This study included 47 chronic hemodialysis patients. Patient characteristics were recorded. Blood was drawn before and after hemodialysis session. Serum BPA levels were measured by the high-performance-liquid-chromatography and laboratory parameters were measured by using standard methods. RESULTS: In hemodialysis patients, postdialysis serum BPA levels were significantly higher than predialysis after a single hemodialysis session (5.57 ± 1.2 vs. 4.06 ± 0.73, p < 0.0001). Predialysis serum BPA levels were significantly higher in patients with diabetes than non-diabetics (4.4 ± 0.6 vs. 3.9 ± 0.7, p = 0.025). No association was found between serum BPA levels and patient characteristics, and particularly laboratory parameters. CONCLUSION: Serum BPA levels were rising significantly after a single dialysis session. Diabetic hemodialysis patients had higher predialysis serum BPA levels.

BACKGROUND: This study aimed to detect the presence of the parasite Demodex folliculorum (DF) in various obese groups according to BMI Levels. MATERIALS AND METHODS: A total of 182 patients (40.8 ± 14.8 years, min-max age 19 - 73 years) were enrolled in the study, of those 65 (35.7%) were female and 117 (64.3%) were male. They had previously applied to Mustafa Kemal University (Faculty of Medicine, Endocrine Outpatient Clinic) during 2012. A standardized skin surface biopsy method was used to research the existence of DF. Patients were classified into four main groups, including: obese (n = 89), overweight (n = 31), normal (n = 32), and underweight (n = 30). RESULTS: There was no significant difference between groups in terms of age and sex. The total DF positivity was 19 (21.3%) in obese patients. Among those with positive DF, the mean BMI was 35.7 ± 12.1 kg/m(2), while those with negative DF had a mean BMI of 29.2 ± 9.2 kg/m(2). There was a significant difference between two groups (P = 0.002). Also, the underweight group has significantly higher DF positivity in comparison to the normal weight group. CONCLUSION: The DF positivity was significantly higher in obese patients in accordance with the physiopathologic nature of the disease.

The determination of phthalates in edible oils (virgin olive oil, olive oil, canola oil, hazelnut oil, sunflower oil, corn oil) sold in Turkish markets was carried out using gas chromatography-mass spectrometry. Mean phthalate concentrations were between 0.102 and 3.863 mg L(-1) in virgin olive oil; 0.172 and 6.486 mg L(-1) in olive oil; 0.501 and 3.651 mg L(-1) in hazelnut oil; 0.457 and 3.415 mg L(-1) in canola oil; 2.227 and 6.673 mg L(-1) in sunflower oil; and 1.585 and 6.248 mg L(-1) in corn oil. Furthermore, the influence of the types of oil and container to the phthalate migration was investigated. The highest phthalate levels were measured in sunflower oil. The lowest phthalate levels were determined in virgin olive oil and hazelnut oil. The highest phthalate levels were determined in oil samples contained in polyethylene terephthalate.

BACKGROUND: Post-adolescent acne has been defined as acne in a patient aged >25 years. Acne vulgaris first develops at the onset of puberty as a result of hormonal changes. During puberty, there is a transient decline in insulin sensitivity. We hypothesized that insulin resistance might persist after puberty in patients with post-adolescent acne. OBJECTIVES: This study was conducted in order to investigate the relationship between post-adolescent acne and insulin resistance. METHODS: The study population comprised 35 patients with post-adolescent acne and 35 healthy control subjects. The parameters measured were fasting blood glucose, insulin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). The homeostasis model assessment of insulin resistance (HOMA-IR) index was calculated for each individual. RESULTS: No significant differences were observed between patients with post-adolescent acne and control subjects in fasting blood glucose, fasting insulin, AST, ALT, triglyceride and HDL-C levels, and HOMA-IR index. There were also no correlations between these parameters and the severity of acne. CONCLUSIONS: This study suggests that insulin resistance may not play a major role in the pathogenesis of post-adolescent acne. Hormonal changes, genetic susceptibility, stress, the use of cosmetics, drugs, and environmental factors should be considered in the development of post-adolescent acne.

Alström syndrome (ALMS) is an autosomal recessive disease characterized by multiple organ involvement, including neurosensory vision and hearing loss, childhood obesity, diabetes mellitus, cardiomyopathy, hypogonadism, and pulmonary, hepatic, renal failure and systemic fibrosis. Alström Syndrome is caused by mutations in ALMS1, and ALMS1 protein is thought to have a role in microtubule organization, intraflagellar transport, endosome recycling and cell cycle regulation. Here, we report extensive phenotypic and genetic analysis of a large cohort of Turkish patients with ALMS. We evaluated 61 Turkish patients, including 11 previously reported, for both clinical spectrum and mutations in ALMS1. To reveal the molecular diagnosis of the patients, different approaches were used in combination, a cohort of patients were screened by the gene array to detect the common mutations in ALMS1 gene, then in patients having any of the common ALMS1 mutations were subjected to direct DNA sequencing or next-generation sequencing for the screening of mutations in all coding regions of the gene. In total, 20 distinct disease-causing nucleotide changes in ALMS1 have been identified, eight of which are novel, thereby increasing the reported ALMS1 mutations by 6% (8/120). Five disease-causing variants were identified in more than one kindred, but most of the alleles were unique to each single patient and identified only once (16/20). So far, 16 mutations identified were specific to the Turkish population, and four have also been reported in other ethnicities. In addition, 49 variants of uncertain pathogenicity were noted, and four of these were very rare and probably or likely deleterious according to in silico mutation prediction analyses. ALMS has a relatively high incidence in Turkey and the present study shows that the ALMS1 mutations are largely heterogeneous; thus, these data from a particular population may provide a unique source for the identification of additional mutations underlying Alström Syndrome and contribute to genotype-phenotype correlation studies.

The aim of the study was to investigate serum 25-hydroxyvitamin D (25(OH) D3) levels in patients with vitiligo vulgaris in terms of causal relation and extension of the disorder. This study is a clinical cross-sectional study carried out in order to determine 25-hydroxyvitamin D levels among 25 patients with vitiligo vulgaris and in 41 controls. Fitzpatrick skin phototypes, history of autoimmune disease, family history of vitiligo, and duration of the disease were also evaluated. The mean levels of vitamin D in patient and the control group were 15.2±5.2 ng/dL and 14.4±6.2 ng/dL respectively (P>0.05). In our study, 48% of the patients had insufficient (<30 ng/mL) and 52% had very low (<15 ng/mL) levels of vitamin D. There was no correlation between age, duration of the disease, and body surface area affected with vitamin D levels. There was no significant difference in vitamin D levels between patients who had family history of vitiligo (5 patients, 20%) and those that did not. Vitamin D levels were found to be insufficient (<30 ng/mL) or very low (<15 ng/mL) in most of the patients with vitiligo vulgaris, but not statistically significantly different as a group when compared to the controls. More studies are needed to differentiate between the effects of low vitamin D levels on pathogenesis of vitiligo vulgaris and lower vitamin D levels as a result of the disease.

INTRODUCTION: Diabetic foot is a clinical disorder, which is commonly seen in patients with diabetes mellitus. It is also the major cause of below knee amputation in the world. There are many underlying causes such as neuropathic, ischemic, and infectious causes for diabetic foot. Local or systemic complications may develop after snake bite. CASE PRESENTATION: We reported a very rare case, involving a 78-year-old male admitted to the Emergency Department, who developed anaphylactic shock and diabetic foot after the snake bite. CONCLUSIONS: Reviewing the literature, this is the second reported case of snake bite associated with diabetic foot.
RESUMO
OBJECTIVE: Platelets have an important role in atherosclerosis and arterial thrombosis. Cardiovascular complication prevalence of type 2 diabetes mellitus (type 2 DM) may be associated with glycosylated hemoglobin (HbA1c) and mean platelet volume (MPV). The aim of the study was to investigate if platelets were activated in diabetes and its associated vascular complications by measuring the MPV in the diabetics compared to the non-diabetics, and to determine the correlation of MPV with fasting serum glucose (FSG), HbA1c and duration of diabetes in the diabetic patients, respectively. MATERIALS AND METHODS: The study carried out in 65 patients with type 2 DM and 40 non-diabetic subjects. In addition to non-diabetic patients, all diabetic patients were divided into two groups according to their HbA1c levels: group A consisted of patients with HbA1c levels ≤7% and group B consisted of patients with HbA1c levels >7%. RESULTS: MPV was significantly higher in Group B as compared to both non-diabetics and Group A. MPV had a high positive correlation with HbA1c and FSG, as with diabetes duration. It is found that MPV was increased in type 2 DM. CONCLUSION: Our findings suggested an association between MPV and HbA1c. Therefore, MPV would be a beneficial prognostic marker of cardio-vascular complications in patients with type 2 DM.
RESUMO
Accompanying comorbidities observed during the cancer treatment usually affect the course and outcome of the therapy. Hypovitaminosis D, which is one of these conditions, is a resolvable problem, if recognized. In this study, we investigated whether the serum 25(OH)D levels of the patients who were presented to our outpatient clinic were different from the serum levels of the healthy population living in the same area. Our study included 90 patients who were presented to the Medical Oncology outpatient clinic and 90 age, gender, body mass index and ethnic origin matched controls without a known disease, who were presented to the outpatient clinics of the Departments of Internal Diseases and Family Medicine for routine controls. Blood count tests, detailed biochemistry tests (including serum levels of Cr, Ca and P), measurement of serum 25(OH)D levels and C-reactive protein were performed in serum samples of all of the patients and controls. Mean serum levels of 25(OH)D were 13.5 ng/ml (SD 5.1) in all cancer patients, 13.1 ng/ml (SD 4.2) in the patients who were presented for adjuvant therapy, 13.8 ng/ml (SD 5.5) in the patients who were presented at metastatic stage and 18.4 ng/ml (SD 12.5) in the controls. Mean serum CRP levels were 5.4 mg/dl (SD 1.2) in the control group, 8.4 mg/dl (SD 4.3) in the adjuvant therapy group and 20.3 (SD 16.8) in the patients with metastatic disease. Generally, all cancer patients (p 0.003) and the patients with metastatic cancer (p 0.004) had lower serum 25(OH)D levels compared to controls, and there was an inverse correlation between serum 25(OH)D and CRP levels in patients with metastatic cancer (p 0.036). In metastatic cancer patients, hypovitaminosis D may be a comorbidity and it is recommended to consider during initial evaluation and follow-up. Because it might improve these patients quality of life and chemotherapy adherence.

OBJECTIVE: Leukocytosis is thought to be directly associated with the pathogenesis of atherosclerosis and metabolic syndrome. Increased white blood cell (WBC) count is related to cardiovascular disease in patients with type 2 diabetes mellitus; raised neutrophil lymphocyte ratio (NLR) is associated with metabolic syndrome. There is little information, however, concerning a correlation between glycosylated haemoglobin (HbA1c) and NLR. The aim of the present study was to investigate the relationship between NLR and blood glucose regulation. METHODS: This retrospective study was conducted in patients with type 2 diabetes mellitus, divided into two groups according to HbA1c levels: group 1, HbA1c levels ≤ 7%; group 2, HbA1c levels > 7%. Venous WBC, neutrophil and lymphocyte counts were determined. RESULTS: Of 71 patients included, fasting serum glucose, neutrophil and WBC counts were significantly higher in group 2 compared with group 1. NLR had a positive correlation with HbA1c. CONCLUSION: There may be a significant relationship between NLR and blood glucose regulation. The authors propose that increased NLR may be associated with elevated HbA1c in patients with type 2 diabetes mellitus.

Obstructive sleep apnea syndrome (OSAS) is a common health problem, and associated with obesity, metabolic syndrome (MetS), and diabetes. Growing evidence shows that 25-hydroxyvitamin-D3 (25-OH-D) insufficiency and high parathyroid hormone (PTH) levels may be correlated to glucose intolerance, MetS, obesity, and cardiovascular abnormalities similar to OSAS. Bisphenol A (BPA) is an endocrine disruptor agent which exerts a wide variety of metabolic effects. It has estrogenic activity and its exposure may contribute to weight gain, obesity, impaired glucose metabolism, and the development of diabetes, also similar to OSAS. The aim of this study is to investigate the relationships between OSAS and serum BPA, 25-OH-D, and PTH levels. This study enrolled 128 subjects, with all of the OSAS patients having been diagnosed by polysomnography. The 128 subjects were divided into three groups: a control (n = 43), a moderate OSAS (n = 23) (AHI = 15-30), and a severe OSAS groups (n = 62) (AHI > 30). The serum BPA, 25-OH-D, and PTH levels for each subject were analyzed. 25-OH-D was lower in both OSAS groups, and PTH was higher in the OSAS groups than in the control subjects. The BPA levels were higher in the severe OSAS group than the moderate OSAS and control. There was a positive correlation between the BPA and body mass index, and a negative correlation between the 25-OH-D and BPA levels in all of the individuals. OSAS is related to high BPA and PTH levels, and low vitamin D levels. There is a positive association between BPA levels and OSAS, and the severity of OSAS. These results suggest that the BPA levels may have a role in the pathogenesis of OSAS.

BACKGROUND: Radioactive iodine (RAI) therapy is preferred in the treatment of hyperthyroidism because of its effectiveness, noninvasiveness, and low costs. I has been detected in extrathyroidal tissues, such as in gastric mucosa, salivary glands, and lacrimal glands. To the best of our knowledge, there is no publication concerning the effects of RAI therapy for hyperthyroidism on tear production. In the present study, we evaluated whether or not the lacrimal glands are affected after RAI therapy when compared with pretreatment period. METHODS: The Schirmer and tear break-up time (TBUT) tests were used to assess 32 eyes of 16 patients with conditions that were diagnosed as hyperthyroidism before and at 3 and 6 months after RAI treatment. In addition, pretreatment values of patients were compared with that of controls. It was evaluated whether or not a correlation exists between the results and the dose or iodine uptake values. RESULTS: There was no significant difference between pretreatment values of Schirmer and TBUT tests obtained in the patient group and those of the control group (P > 0.05). In the patient group, there was a significant difference between the posttreatment and pretreatment values (P < 0.05). There was a positive correlation between uptake values obtained at 24 hours and the values obtained by TBUT and Schirmer tests on both eyes at 3 and 6 months. At 6 months, the uptake value at 24 hours was 28.83 ± 60 for both eyes in patients with TBUT test values less than 10, whereas it was 39.25 ± 7.88 for the right eye and 39.00 ± 6.85 for the left eyes in patients with TBUT test values greater than 10. The difference was statistically significant (P < 0.05). CONCLUSIONS: In our study, we concluded that the decrease in mucin and aqueous production occurs due to affected lacrimal glands by RAI therapy; however, this effect is not dose dependent.

OBJECTIVES: To evaluate the effect of mean platelet volume (MPV) on diabetic retinopathy in patients with type 2 diabetes mellitus. MATERIALS AND METHODS: In this study, ocular findings and MPV values were retrospectively reviewed in 192 patients with type 2 diabetes mellitus. The patients were classified into four groups according to ocular findings, as follows: group 1, diabetic patients without diabetic retinopathy (n = 70); group 2, diabetic patients with non-proliferative diabetic retinopathy (n = 64); group 3, diabetic patients with proliferative diabetic retinopathy (n = 58); and group 4, healthy controls (n = 100). RESULTS: A significant difference was found in MPV values between groups 2 and 4 (P = 0.001), between groups 3 and 4 (P = 0.001), and between groups 1 and 4 (P = 0.004). No significant difference was found in MPV values between groups 1 and 2 (P = 0.241) and between groups 2 and 3 (P = 0.460); whereas there was a statistically significant difference between groups 1 and 3 (P = 0.015). The three diabetic groups (groups 1, 2, and 3) were compared with each other. While there was a statistically significant difference between groups 1 and 3 (P = 0.015), there was no significance between groups 2 and 3 (P = 0.46), and between group 1 and 2 (P = 0.241). Logistic regression analysis found a 1.40-fold increase in the risk of retinopathy development (OR: 1.404; P = 0.002) and a 1.46-fold increase in the risk of proliferative diabetic retinopathy (OR: 1.466; P = 0.002) as the MPV value increased. CONCLUSIONS: In diabetic patients, the risk of retinopathy development increases with higher MPV values.

OBJECTIVES: To measure the rate of Demodex folliculorum mite infestation in patients with type 2 diabetes mellitus and to investigate if it was related to blood glucose control. METHODS: Patients with type 2 diabetes were classified according to their glycosylated haemoglobin (HbA(1c)) level into two groups: a well controlled blood glucose group (HbA(1c) ≤ 7%) and a poorly controlled blood glucose group (HbA(1c) > 7%). A standardized skin surface biopsy method was used to determine if the patients had D. folliculorum infestation (>5 mites/cm² of skin). RESULTS: A total of 69 patients (38 female) were enrolled in the study. Seventeen (24.6%) patients had D. folliculorum infestation. There were no significant differences in age, sex or body mass index between patients with and without D. folliculorum infestations. A significantly higher proportion of patients with poor blood glucose control had D. folliculorum infestation compared with patients with well controlled blood glucose. CONCLUSIONS: These current findings suggest that poor blood glucose regulation increases the susceptibility to D. folliculorum mite infestation in patients with type 2 diabetes.
