RESUMEN
Managing dyslipidaemia is central to the management of cardiovascular disease. Statins are the cornerstone of cardiovascular prevention for general population, and in patients with type 2 diabetes mellitus. However, statin therapy predisposes to type 2 diabetes, particularly in patients with predisposition to this condition. Some statins have been associated with increases in blood glucose in patients, and others have shown to have neutral effects, varying from one another their glucose or diabetogenic capacity. Pitavastatin is a new member of the statin class. And pitavastatin has a number of pleiotropic effects that can reduce inflammation and lipid oxidation, improve endothelial function, reduce the metabolic changes associated with adiposity, and improve glucose metabolism and renal function.

OBJECTIVE: To investigate the benefits of ultrasound-assisted guided wire localization in MIP for selected cases. METHODS: In this prospective, nonrandomised study, we included 36 patients with solitary parathyroid adenomas diagnosed preoperatively by 99m Tc sesta MIBI scintigraphy and/or neck ultrasonography. An ultrasound-guided wire was placed in the solitary parathyroid adenoma preoperatively. MIPs were performed under local anaesthesia plus sedation. After the excision, the parathyroidectomy was confirmed with postoperative ultrasonography. RESULTS: There were 36 patients included in our study. The mean age was 54.89±11.28 years, and 30 patients were females (83.3%). Preoperative PTH and calcium (Ca) levels were 269.5 pg/mL (83.5-5,000 pg/mL) and 12.2 mg/dL (11.1-20 mg/dL), respectively. Postoperative serum PTH and Ca levels were 42.04±26.65 pg/mL and 8.95±0.74 mg/dL, respectively. The mean operation time was 21.69±6.4 minutes and the average hospitalisation time was 18 hours (range: 10-72 hours). CONCLUSIONS: Ultrasound-assisted guided wire localization may be useful in selected MIP cases. The MIP advantages include higher success rates and being easy to learn and practise.

Löfgren's syndrome is an acute clinical form of sarcoidosis that is first described by Sven Löfgren as bilateral hilar lymphadenopathy together with Erythema Nodosum (EN) and accompanying arthritis/arthralgia. This syndrome has some differences in terms of treatment, prognosis and recurrence compared to sarcoidosis. In this report, we describe a 70 years old lady who admitted with multiple erythematous lesions and arthralgia of both lower extremities and she was diagnosed as Löfgren's syndrome via mediastinoscopy.

AIM OF THE STUDY: Primary squamous cell carcinoma (SCC) of the thyroid gland is extremely rare. Infrequently, primary SCC of the thyroid gland is accompanied by other thyroid diseases such as Hashimoto's thyroiditis (HT). Recently, studies have demonstrated that differentiated thyroid cancer with coexisting HT has a better prognosis. However, the prognosis of patients with primary SCC of the thyroid gland and coexistent HT has not been clearly identified. We compared the clinical characteristics and disease stages of patients with primary SCC with and without lymphocytic thyroiditis (LT). MATERIAL AND METHODS: We reviewed reports of primary SCC of the thyroid gland published in the English literature. RESULTS AND CONCLUSIONS: We identified 46 papers that included 17 cases of primary SCC of the thyroid gland with LT and 77 cases of primary SCC of the thyroid gland without LT. Lymph node metastasis and local invasion rates did not differ between these two groups. Distant metastases were absent in patients with LT, and were observed in 13 (16.9%) patients without LT. A greater proportion of patients without LT had advanced stage disease (stage IV A-B-C) than patients with LT (p < 0.05). Patients with primary SCC of the thyroid gland and coexisting LT had lower tumour-node-metastasis stage and frequency of distant metastasis than those without LT. Lymphocytic infiltration in patients with SCC appears to limit tumour growth and distant metastases.
RESUMEN
OBJECTIVE: The liver is an important organ for various aspects of glucose metabolism, including glucose uptake, storage, and synthesis. It is a major organ in the metabolic process with perfusion provided by both the portal vein and hepatic artery. In diabetic patients organ perfusion is reduced and this is linked to atherosclerosis, and as a result complications occur. In this study, we aimed to evaluate liver perfusion by scintigraphic methods in diabetic patients. DESIGN AND PATIENTS: We retrospectively investigated 1,100 myocardial perfusion scintigraphies taken between January 2011 and December 2012 at Canakkale Onsekiz Mart University Medical Faculty Nuclear Medicine Department. A total of 66 patients who were diagnosed with diabetes mellitus and had myocardial perfusion scintigraphies were included in the study. The control subjects included 127 patients without diabetes mellitus who were chosen at random. Patients with chronic liver disease were not included in the study. The values from liver regions of interest (liver-ROI) rates and heart regions of interest (heart-ROI) rates were compared between the patients and controls. RESULTS: Patients were grouped according to the presence of diabetes. In the diabetes mellitus group, the liver-ROI average was lower (p = 0.66) than in the controls. In the control group, the average liver-ROI/heart-ROI ratios were higher than the ratio in the diabetes mellitus group (p = 0.019). Multivariate variance analysis showed that the diabetes mellitus liver-ROI/heart-ROI ratio was independent of other risk factors (p = 0.003; F: 9.6).

CONCLUSIONS: This study shows that liver perfusion in diabetic patients is reduced compared with those without diabetes. Prospective studies with larger patient groups are required.

OBJECTIVE: Hypothyroidism (HT) has an increased risk for cardiovascular mortality and morbidity due to increased atherosclerosis. Heart-type fatty acid binding protein (H-FABP) is abundant in the cytosol of cardiomyocytes, and transports fatty acids into these cells. Although H-FABP has been shown to increase in several atherosclerotic and inflammatory conditions, there is no literature data indicating an alteration in other atherosclerotic processes such as HT. MATERIAL AND METHODS: A total of 39 patients with subclinical hypothyroidism (SCH), 26 patients with overt hypothyroidism (OH), and 29 healthy subjects were enrolled in this study. Carotid artery intima media thickness (CIMT) was measured by high resolution B mode ultrasonography. H-FABP levels, thyroid function test, and biochemical tests of all subjects were measured. The associations between H-FABP and thyroid test and CIMT were examined with correlation and regression analysis. RESULTS: OH patients had higher H-FABP levels (mean, 6.18 ± 3.08 ng/mL) than both the SCH (mean, 3.81 ± 2.16 ng/mL) and the controls (mean, 2.12 ± 1.27 ng/mL) (P < 0.01 and < 0.001, respectively). SCH patients had increased serum H-FABP levels compared with control subjects (P < 0.01). CIMT of both OH and SCH patients was also significantly greater compared with control subjects (both of p < 0.01). H-FABP was significantly and positively correlated with age, systolic blood pressure, thyroid stimulating hormone (TSH) levels, and CIMT, and negatively correlated with fT4 levels. The H-FABP levels retained an independent and positive association with systolic blood pressure, and a negative association with fT4 levels. CONCLUSION: Serum H-FABP levels progressively increased from the control group to the OH group. This suggests that H-FABP may be an indicator of low-level myocardial damage in HT, especially when used together with CIMT. Decreasing serum fT4 levels seem also to have an effect on H-FABP levels.

OBJECTIVE: Primary hyperparathyroidism (pHPT) affects the cardiovascular system, and epicardial fat tissue (EFT) thickness is closely associated with cardiovascular diseases and atherosclerosis. Despite this, the association between EFT thickness and pHPT has not been studied in a clinical setting. This study aimed to assess EFT thickness in patients with pHPT. METHODS: The study included 38 patients with pHPT and 40 healthy controls. EFT thickness, carotid intima-media thickness (CIMT), serum levels of parathormone (PTH) and calcium, and blood chemistry profiles were determined in all subjects. Correlation and regression analyses were performed with EFT thickness and CIMT as dependent variables and age; systolic and diastolic blood pressure; body mass index (BMI); presence of diabetes mellitus; and free plasma glucose (FPG), PTH, and serum calcium (Ca) levels as independent variables. RESULTS: Both the mean EFT thickness and the mean CIMT were significantly greater in the pHPT group than the control group (P < .001 for both). Correlation analysis showed that EFT thickness was significantly correlated with CIMT, age, systolic blood pressure, and PTH and serum Ca levels. Furthermore, the regression analysis revealed that EFT thickness retained its independent and positive association with FPG and serum Ca levels. CONCLUSIONS: The results of this study indicate that EFT thickness may be a useful marker of early atherosclerosis in patients with pHPT. Furthermore, the increase in EFT thickness appears to be due to hypercalcemia.

We aimed to evaluate the prevalence of lactose intolerance (LI) in patients with Hashimoto's thyroiditis(HT) and the effects of lactose restriction on thyroid function in these patients. Eighty-three HT patients taking L-thyroxine (LT4) were enrolled, and lactose tolerance tests were performed on all patients. Lactose intolerance was diagnosed in 75.9 % of the patients with HT. Thirty-eight patients with LI were started on a lactose-restricted diet for 8 weeks. Thirty-eight patients with LI (30 euthyroid and 8 with subclinical hypothyroidism), and 12 patients without LI were included in the final analysis. The level of TSH significantly decreased in the euthyroid and subclinical hypothyroid patients with LI [from 2.06 ± 1.02 to 1.51 ±1.1 IU/mL and from 5.45 ± 0.74 to 2.25 ± 1.88 IU/mL,respectively (both P<0.05)]. However, the level of TSH in patients without LI did not change significantly over the 8 weeks (P>0.05). Lactose intolerance occurs at a high frequency in HT patients. Lactose restriction leads to decreased levels of TSH, and LI should be considered in hypothyroid patients who require increasing LT4 doses,have irregular TSH levels and are resistant to LT4 treatment.

Graves' disease and Hashimoto's thyroiditis are the most common autoimmune thyroid diseases. Hypothyroidism can develop in patients with Graves' disease, either spontaneously or as a result of radioactive iodine therapy or surgery. However, it is rare for patients with Hashimoto's thyroiditis to subsequently develop Graves' disease. We report a case of alopecia areata associated with Graves' disease in a 41-year-old woman who had previously been diagnosed with Hashimoto's disease. Alopecia areata is an autoimmune disease associated with other autoimmune diseases such as thyroid disorders, anemia, and other skin disorders.

Ischemia-modified albumin (IMA) is a novel marker of tissue ischemia. Nowadays, IMA is accepted as a marker of oxidative stress. In this study, we aimed at establishing an association between IMA and hyperglycemia, blood pressure, lipid parameters, microvascular complications, hsCRP, and microalbuminuria in type 2 diabetes patients without overt macrovascular disease and acute ischemia. Fifty type 2 diabetes mellitus patients without a history of macrovascular disease or end-stage renal disease were enrolled into the study. Age-matched 30 healthy individuals were also included in the study as a control group. Plasma IMA (0.329 ± 0.046 and 0.265 ± 0.045 AbsU; P < 0.0001) and hsCRP levels (0.51 ± 0.36 and 0.32 ± 0.17 mg/dl; P < 0.0001) were significantly higher in the diabetic group compared to healthy controls. IMA level was significantly correlated with hsCRP (r = 0.76; P < 0.0001), HbA1c (r = 0.72; P < 0.0001), microalbuminuria (r = 0.40; P = 0.004), systolic blood pressure (r = 0.28; P = 0.049), diastolic blood pressure (r = 0.44; P = 0.005), and HOMA-IR (r = 0.42; P = 0.005) levels in the entire diabetic subjects. In the diabetic patients group, presence of microalbuminuria was associated with a higher plasma IMA level (0.355 ± 0.035 and 0.265 ± 0.0045 AbsU; P < 0.0001, patients with microalbuminuria and control subjects, respectively). In the type 2 diabetes patients with nephropathy, IMA level (0.355 ± 0.035 and 0.311 ± 0.046 AbsU; P = 0.002) was determined higher compared to the diabetes patients without nephropathy. Diabetic patients without an overt cardiovascular disease still have a higher serum IMA level compared to healthy controls. The correlation of high plasma IMA levels with high hsCRP and microalbuminuria levels in diabetic subjects indicates the presence of a chronic ischemic process. Therefore, elevated IMA levels may indicate an underlying subclinical vascular disease in type 2 diabetes mellitus patients.

Hyperhomocysteinemia is a well-defined risk factor for endothelial dysfunction and atherosclerosis. A point mutation (677 C-T) of MTHFR gene results in a significant increase at plasma homocysteine levels. In this study we aimed to evaluate the effects of MTHFR gene mutation and consequent hyperhomocysteinemia on the development of diabetic microvascular complications in comparison with the other defined risk factors. Diabetic patients without a history of macrovascular complication or overt nephropathy enrolled into the study. The presence of MTHFR 677 C-T point mutation was evaluated by Real-Time PCR technique by using a LightCycler. MTHFR heterozygous mutation was present in 24 patients over 52. Patients with diabetes were divided into two groups according to the presence of MTHFR gene mutation. Both groups were well matched regarding age and diabetes duration. Metabolic parameters, plasma homocysteine, microalbuminuria, folic acid, and vitamin B12 levels were also studied. Presence of neuropathy and retinopathy were evaluated by specific tests. Duration of diabetes, BMI, systolic and diastolic blood pressure, plasma CRP, HbA1c, and lipid levels were not different between the two groups. Plasma homocysteine (12.89 +/- 1.74 and 8.98 +/- 1.91 micromol/l; P < 0.0001) and microalbuminuria levels (73.40 +/- 98.15 and 29.53 +/- 5.08 mg/day; P = 0.021) were significantly higher in the group with MTHFR gene mutation while creatinine clearance levels (101.1 +/- 42.6 and 136.21 +/- 51.50 ml/min; P = 0.008) were significantly lower. Sixteen over 22 (73%) of the patients with diabetic nephropathy had MTHFR gene mutation, while this was only 27% (8 over 30) in normoalbuminuric patients (P = 0.017). There was a significant correlation of plasma homocysteine level with microalbuminuria (r = 0.54; P = 0.031) in the patients with diabetic nephropathy who had C677T polymorphism. We did not find any specific association of MTHFR gene mutation and hyperhomocysteinemia with retinopathy or neuropathy.

Adequate exposure to sunlight and fortification of dairy products with vitamin D have eliminated vitamin D deficiency secondary to inadequate endogenous production or nutrition in the majority of countries. Insufficient vitamin D intake secondary to using unfortified foods and social customs (such as avoiding sun exposure), however, contribute to the development of disease. Poor diet, a lack of sun exposure, and the age related decline in the dermal synthesis of 7-dehydrocholesterol are among the factors that predispose to vitamin D deficiency and consequent bone disease. Here, we present a case of severe osteomalacia presenting with multiple vertebral fractures due to poor diet and a lack of exposure to sunlight.

Thyroid dermopathy is not a frequent feature of hyperthyroid Graves' disease, being present in less than 5% of the patients. Graves' disease has been shown to exist in euthyroid or hypothyroid forms in untreated patients. Here, we describe a case of hypothyroid Graves' disease with elephantiasis nostras verrucosa (ENV), which is an extreme form of thyroid dermopathy (TD). A 58-year-old female patient was admitted to the emergency department with somnolence, hypothermia, and bradycardia. Her mental status gradually worsened, resulting in a deep coma. She was intubated and followed in the intensive care unit, as she needed mechanical ventilatory assistance due to respiratory failure. She also had bilateral non-pitting edema, a cobblestone-like appearance, and hyperkeratotic greenish-brown-colored lesions in the pretibial and dorsal regions of the feet that were compatible with ENV. Hypothyroid Graves' disease is a very rare condition among autoimmune thyroid disorders, and ENV is an extremely rare form of TD. Here, we present a patient with hypothyroid Graves' disease and ENV.

Type 2 diabetes mellitus is the leading cause of macrovascular diseases and related death. Additionally, diabetes mellitus is frequently complicated by other cardiovascular risk factors, such as hypercholesterolemia, hypertension, obesity, hypercoagulability, and inflammation. We wanted to evaluate and compare the effects of treating with a one-year course of atorvastatin or simvastatin on inflammatory markers such as high sensitive C-reactive protein (hsCRP), fibrinogen, and ferritin in uncontrolled type 2 diabetic patients. Also, we planned to investigate the correlation between inflammatory markers and metabolic parameters. Fifty type 2 diabetic patients (30 women, 20 men; mean age: 49.9 +/- 8.5 years) were enrolled into the study. Twenty healthy subjects, matched on body mass index and age, were also included in the study as a control group. Diabetic patients were divided into two groups and received simvastatin or atorvastatin (Group S and A, respectively). After 1 year of statin treatment (Group A), there were significant decreases in total cholesterol (217.3 +/- 46.5-173.8 +/- 37.2 mg/dl; P < 0.0001), LDL-cholesterol (146.7 +/- 50.3-102.3 +/- 31.1 mg/dl, P < 0.0001), hsCRP (0.88 +/- 0.62-0.35 +/- 0.18 mg/dl, P < 0.0001), fibrinogen (258.2 +/- 16.9-215.5 +/- 10.6 mg/l; P < 0.0001), and ferritin (118.2 +/- 73.9-81.2 +/- 72.5 ng/ml, P < 0.0001) levels compared to basal values. In the S group, there were significant decreases in total cholesterol (224.4 +/- 61.2-175.0 +/- 47.8 mg/dl; P < 0.0001), LDL-cholesterol (140.9 +/- 56.7-110.9 +/- 42.2 mg/dl, P < 0.0001), hsCRP (0.98 +/- 1.3-0.46 +/- 0.25 mg/dl, P < 0.0001), fibrinogen (265.7 +/- 26.8-222.1 +/- 20.6 mg/l; P < 0.0001), and ferritin (136.7 +/- 101.1-85.6 +/- 32.1 ng/ml, P < 0.0001) levels compared to basal values. At the end of the study, hsCRP, fibrinogen, and ferritin levels were correlated with LDL (r = 0.42; P = 0.005, with hsCRP), (r = 0.40; P = 0.008, with fibrinogen), (r = 0.46; P = 0.002, with ferritin) and HDL (r = -0.50; P < 0.0001, with hsCRP), (r = -0.32; p = 0.042, with fibrinogen), (r = -0.48; P < 0.0001, with ferritin) cholesterol levels. Atorvastatin and simvastatin treatments were found to be effective for the control of hypercholesterolemia and resulted in a significant decrease in acute phase reactants in uncontrolled type 2 diabetic patients.

Diagnosis of polycystic ovary syndrome (PCOS) is very difficult in women with ovulatory cycles. We assessed the diagnostic value of prostate-specific antigen (PSA) and free prostate-specific antigen (fPSA) in women with ovulatory or anovulatory PCOS. Study group consisted of 62 women with PCOS and 35 healthy female controls. PCOS group was divided into two subgroups as anovulatory (n = 42; 68%, Group A) and ovulatory group (n = 20; 32%, Group B). A cut-off level of PSA and fPSA was established for the sensitivity, specificity, positive likelihood ratio, area under curve, diagnostic accuracy, and positive and negative predictive values of diagnosis of PCOS. In group A, a PSA level of greater than 10 pg/ml yielded a sensitivity of 73.2%, a specificity of 80%, and a diagnostic accuracy of 73%, with a positive predictive value of 88.2% and a negative predictive value of 59.3%. An fPSA level of greater than 2.1 pg/ml yielded a sensitivity of 71.2%, a specificity of 80.4%, and a diagnostic accuracy of 87%, with a positive predictive value of 87.2% and a negative predictive value of 58.4%. In group B, a PSA level of greater than 10 pg/ml yielded a sensitivity of 65%, a specificity of 80%, and a diagnostic accuracy of 73%, with a positive predictive value of 76.5% and a negative predictive value of 69.6%. An fPSA level of greater than 2.1 pg/ml yielded a sensitivity of 65.4%, a specificity of 80.4%, and a diagnostic accuracy of 87%, with a positive predictive value of 75.5% and a negative predictive value of 68.4%. Circulating androgens and hirsutism are independently associated with the degrees of PSA and fPSA in PCOS women. Increased plasma levels of PSA (>10 pg/ml) and fPSA (>2.1 pg/ml) could be helpful as a diagnostic tool for women with ovulatory or anovulatory PCOS.

Carbohydrate intolerance is a common feature of acromegaly. Frank diabetes mellitus is seen in about 10-20% of patients. There is no report of acromegaly presenting with diabetic ketoacidosis (DKA), associated with retinitis pigmentosa (RP), in the literature. We report the occurrence of DKA and RP in a patient with acromegaly. A 39-year-old Turkish man was admitted to the emergency ward with a 1-mo history of thirst, polyuria, weight loss of 10 kg, and loss of consciousness for 2 d. Physical examination revealed findings suggestive of acromegaly, including coarse facial features and enlargement of his hands and feet. At ophthalmological examination, funduscopy showed RP. Laboratory studies confirmed the diagnoses of DKA and acromegaly. Magnetic resonance imaging disclosed the presence of a pituitary adenoma. During the medical treatment with octreotide, symptomatic sinusoidal bradycardia was developed (pulse rate 45 bpm, and blood pressure 70/40 mmHg). Octreotide therapy was stopped. Pituitary adenoma was removed surgically. For treatment of DKA, insulin need was very high in the first days after the onset of ketoacidosis, but decreased after initiation of treatment with octreotide and after successful operation. Insulin was stopped 7 d after surgery. Follow-up showed normalization of growth hormone levels and plasma glucose levels. Only six other cases of DKA associated with acromegaly and only three other cases of RP associated with acromegaly were found in the medical literature. In conclusion, to our knowledge, the present case is a first report of DKA and RP in patient with acromegaly.
