Effect of surface treatments on wear and surface properties of different CAD-CAM materials and their enamel antagonists. J Prosthet Dent 2023; 129:495-506. [PMID: 34301415 DOI: 10.1016/j.prosdent.2021.06.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 06/15/2021] [Accepted: 06/15/2021] [Indexed: 10/20/2022]
Abstract
STATEMENT OF PROBLEM Which surface treatment provides optimal surface roughness, microhardness, and wear behavior for computer-aided design and computer-aided manufacturing (CAD-CAM) materials and their enamel antagonists is unclear. PURPOSE The purpose of this in vitro study was to evaluate the effect of surface treatment on the surface roughness, microhardness, and 2-body wear of different CAD-CAM materials and their enamel antagonists. MATERIAL AND METHODS Monolithic zirconia, polymer-infiltrated ceramic network, lithium disilicate, leucite-reinforced ceramic, zirconia-reinforced lithium silicate, and feldspathic ceramic specimens were sliced into 2-mm-thick rectangular plates and divided into polished or glazed subgroups (n=6). After surface roughness and microhardness measurements, the specimens were loaded at 49 N for 250 000 cycles and simultaneously thermocycled (5 °C and 55 °C). All specimens were scanned before and after the wear test by using a scanner. The volumetric loss and wear depth of the materials and the volumetric and height loss of the enamel were calculated, and scanning electron microscope images of the specimens were made. Multiple 2-way ANOVAs and Tukey honestly significant difference tests were used to assess the effect of material and surface treatment on surface roughness, microhardness, and wear behavior of materials and enamel (α=.05). RESULTS Material and surface treatment interactions affected the surface roughness (P<.001), microhardness (P<.001), volumetric loss of materials (P=.044), and height loss of enamel (P<.001). CONCLUSIONS Polishing resulted in higher surface roughness and microhardness than glazing. Volumetric loss depended on the material, which affected the height loss of the antagonists. Glazing and polishing had similar effects on the volumetric loss of materials and antagonists. No correlation was found between the wear of materials and the antagonists, nor between the surface roughness of materials and the volumetric loss of materials or antagonists.

Inadequate gonadal replacement in patients with Turner syndrome may result in pituitary volume enlargement. Curr Med Imaging 2023; 19:CMIR-EPUB-129770. [PMID: 36825729 DOI: 10.2174/1573405619666230223170130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/13/2023] [Accepted: 02/16/2023] [Indexed: 02/25/2023]
Abstract
OBJECTIVES Patients with Turner syndrome need hormone replacement therapy for puberty induction. However, it is not known whether inadequate hormone replacement therapy affects the pituitary. DESIGN AND PATIENTS Patients with Turner syndrome (n=35) and healthy control (n=20) (age/gender matched) subjects were included. MRI imaging of the pituitary was used to calculate pituitary volumes. According to the estradiol regimen, patients were divided into two groups; (i) those treated with low-dose conjugated oestrogen (CE, 0.625 mg) and (ii) those treated with combination therapy (ethinyl estradiol+sipropterone acetate; 35 mcg/2 mg). Pituitary measurements were calculated according to pituitary borders and their distances to each other via pituitary MRI. RESULTS Pituitary hyperplasia (0.58±0.15 cm3 vs. 0.40±0.17 cm3) was determined in patients with low dose conjugated estrogen compared to the other patients or healthy control subjects (0.42±0.16 cm3) (p=0.005). Serum FSH levels of the patients treated with low dose CE were also higher compared to the patients who received combination therapy (p=0.001). CONCLUSION Inadequate hormone replacement therapy can cause devastating effects on the bones and uterine health and disrupts the pituitary structure.

Diabetic foot ulcers: A devastating complication of diabetes mellitus continues non-stop in spite of new medical treatment modalities. World J Diabetes 2022; 13:1106-1121. [PMID: 36578865 PMCID: PMC9791571 DOI: 10.4239/wjd.v13.i12.1106] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 08/21/2022] [Accepted: 11/18/2022] [Indexed: 12/15/2022] Open
Abstract
Diabetic foot ulcer is a devastating complication of diabetes mellitus and significant cause of mortality and morbidity all over the world and can be complex and costly. The development of foot ulcer in a diabetic patient has been estimated to be 19%-34% through their lifetime. The pathophysiology of diabetic foot ulcer consist of neuropathy, trauma and, in many patients, additional peripheral arterial disease. In particular, diabetic neuropathy leads to foot deformity, callus formation, and insensitivity to trauma or pressure. The standard algorithms in diabetic foot ulcer management include assessing the ulcer grade classification, surgical debridement, dressing to facilitate wound healing, off-loading, vascular assessment (status and presence of a chance for interventional vascular correction), and infection and glycemic control. Although especially surgical procedures are sometimes inevitable, they are poor predictive factors for the prognosis of diabetic foot ulcer. Different novel treatment modalities such as nonsurgical debridement agents, oxygen therapies, and negative pressure wound therapy, topical drugs, cellular bioproducts, human growth factors, energy-based therapies, and systematic therapies have been available for patients with diabetic foot ulcer. However, it is uncertain whether they are effective in terms of promoting wound healing related with a limited number of randomized controlled trials. This review aims at evaluating diabetic foot ulcer with regard to all aspects. We will also focus on conventional and novel adjunctive therapy in diabetic foot management.

Abstract
ObjectiveAlthough modified Ferriman-Gallwey (mF-G) scorring has been the gold standard for assessing hirsutism, also known that this scorring could show variability according to ethnicity. Hence, false positive hirsutism diagnosis and unnecessary anti-androgen therapy can prescribed. It was aimed to disclose the regional characteristics of this scorring in healthy women living in Southern Turkey.Methods360 women between 18 and 50 years of age were randomly screened. Their medical history, including ovulation periods, gestation(s), family history, known drug use was obtained. Physical examination with mF-G scoring and serum hormone measurements were performed. Women with hirsutism who scored ≥ 8 were further investigated for any underlying disease or cause of hirsutism. After these investigations, the women were divided into three groups according to the mF-G ≥ 8 score and evaluated. Group A (n = 59) had an mF-G ≥ 8 and, revealed an underlying disease causing hirsutism; group B (n = 42) had an mF-G ≥ 8, but no underlying disease responsible for hirsutism; and the third group (Group C, n = 259) had an mF-G ≤ 8 and thus, no signs of hirsutism.ResultsThe mean mF-G scores of three groups were 12.78 ± 4.4, 11.48 ± 4.6, and 5.53 ± 3.4, respectively. Of the 59 (16.1%) women in Group A, 46 (44.2%) were diagnosed as polycystic ovary syndrome (PCOS), 8 (7.7%) had idiopathic hyperandrogenism, 7 (6.7%) had nonclassic congenital adrenal hyperplasia, and 1 (1%) had a prolactinoma. When compared to group B, group A women had significantly decreased fertility (p = .001) and menstrual irregularities (p = .001).ConclusionsIn this study, results revealed a significant rate of healthy women (11.6%) who had an mF-G ≥ 8, but no underlying disease causing hirsutism yet were considered hirsute according to their mF-G cutoff. Also, the majority of the studied women (71.9%) living in Southern Turkey were found to have a hair-pattern similar to the European Women. Therefore, we suggest that regional and ethnical body-hair patterns should be considered before prescribing anti-androgen therapy.

Effect of multiple firings on surface roughness and flexural strength of CAD-CAM ceramics. J Prosthet Dent 2022; 128:216.e1-216.e8. [PMID: 35788273 DOI: 10.1016/j.prosdent.2022.05.021] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 05/23/2022] [Accepted: 05/24/2022] [Indexed: 10/17/2022]
Abstract
STATEMENT OF PROBLEM Knowledge on the effect of multiple firings on surface roughness and the flexural strength of different types of monolithic computer-aided design and computer-aided manufacturing (CAD-CAM) ceramics is limited. PURPOSE The purpose of this in vitro study was to evaluate the effect of multiple firings on the surface roughness and flexural strength of 4 different CAD-CAM ceramics after thermocycling. MATERIAL AND METHODS Four different CAD-CAM ceramics (Lava All Zirconia 3-mol yttria tetragonal zirconia polycrystal [3-YTZP] [Z], VITA SUPRINITY [S], IPS e.max CAD [EX], IPS Empress CAD [E]) (n=33) were wet-sectioned to form rectangular 18×4×1.2-mm specimens. After glaze application, the specimens were divided into 3 subgroups according to the number of firings (1, 2, and 4) (n=11). The specimens were thermocycled (10 000 cycles), and surface roughness and flexural strength values were measured (n=10). One additional specimen from each group was analyzed by using scanning electron microscopy (SEM). Data were analyzed by 2-way analysis of variance (ANOVA) and the Tukey honestly significance difference (HSD) test (α=.05). RESULTS According to the 2-way ANOVA, the material, number of firings, and the interaction between the material and number of firings affected the surface roughness (P<.001). For flexural strength, material (P<.001) and number of firings (P<.039) were found significant. Multiple firings (2 or 4 firings) affected the surface roughness of E (P<.001). Regardless of the number of firings, the Z material had the highest flexural strength (P<.001). Four firings affected the flexural strength values only for the Z material (P≤.005). CONCLUSIONS CAD-CAM ceramic type affected the surface roughness and flexural strength values. The surface roughness of E was lower when fired 2 or 4 times than when fired once. The flexural strength of Z was lower when fired 4 times than when fired once.

Effect of firing cycle and aging on long-term chemical degradation of monolithic CAD-CAM ceramics. J Prosthet Dent 2022; 128:89.e1-89.e10. [PMID: 35705433 DOI: 10.1016/j.prosdent.2022.04.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 04/29/2022] [Accepted: 04/29/2022] [Indexed: 10/18/2022]
Abstract
STATEMENT OF PROBLEM Previous studies have shown the susceptibility of dental ceramics to degradation when subjected to certain media. However, knowledge on the effect of repeated firings and thermocycling on the ion elution of computer-aided design and computer-aided manufacturing (CAD-CAM) ceramics is lacking. PURPOSE The purpose of this in vitro study was to compare the effect of repeated firings on the ion elution of CAD-CAM materials before and after thermocycling. MATERIAL AND METHODS Bar-shaped specimens were prepared from 4 different CAD-CAM materials (monolithic zirconia [Z], zirconia-reinforced lithium silicate glass-ceramic [S], lithium disilicate glass-ceramic [EX], and leucite-reinforced glass-ceramic [E]) and divided into 3 groups according to the number of repeated glaze firings (1 firing [1F], 2 firings [2F], and 4 firings [4F]). Specimens were placed into deionized water (pH 7.4) and stored at 37 °C for 168 hours. Inductively coupled plasma-optic emission spectrophotometry (ICP-OES) was used to measure the baseline values of the eluted ions in immersion. The specimens were then subjected to thermocycling. Then, surface roughness (Ra) and ion elution values were measured. The Kruskal-Wallis and Mann-Whitney U tests were used to analyze the ion elution data before and after thermocycling, and the effect of thermocycling on ion elution was assessed by the Wilcoxon signed rank test. Ra data were analyzed with 2-way analysis of variance (ANOVA) and the Tukey honestly significant difference tests (α=.05). RESULTS Elution of some ions varied depending on the material-firing pair before (Al, As, B, Ba, Cr, Cu, Li, Mg, Na, P, and Zn) and after (Al, As, B, Ba, Be, Ca, Cd, Co, Cr, Cu, K, Li, Mg, Na, P, Y, and Zn) thermocycling. Before thermocycling, all firing groups within each material showed a similar number of significantly higher eluted ions. After thermocycling, the number of significantly higher eluted ions decreased in all materials, except for EX. The effect of thermocycling on the ion elution of the 1F group of Z (Al, Be, Ca, Cd, Co, Cr, Cu, K, Li, P, Y, and Zn), S (As, Be, Cd, Co, Cr, K, P, and Y), EX (B, Cu, and P), and E (B and Ba); 2F group of Z (Al, Be, Ca, Co, Cr, Cu, K, Li, P, and Y), S (Be, Cd, Co, K, Li, and Y), EX (P), and E (P); 4F group of Z (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, K, Li, P, and Y), S (Al, Be, Cd, Co, Cr, Li, Mg, and Y), EX (Be, Ca, Cd, Co, K, Y, and Zn), and E (Ca and P) was nonsignificant (P≥.051). The interaction between material and repeated firings (P<.001) had a significant effect on Ra. For 1F groups, E showed the highest Ra (P≤.003), while Z had higher Ra than S (P=.009). For 2F groups, Z had higher Ra than S (P=.01). The differences among 4F groups were nonsignificant (P≥.677). An increased number of repeated firings (2F and 4F) decreased the Ra of E (P<.001). CONCLUSIONS The effect of repeated firings and thermocycling on the chemical stability of the tested CAD-CAM materials varied. No clear trend was observed on the elution of different ions within material-firing pairs before thermocycling. However, thermocycling increased the number of significantly higher eluted ions for EX. The effect of thermocycling on the ion elution of materials varied depending on ions. Repeated firings decreased the surface roughness of E.

Abstract
STATEMENT OF PROBLEM Dental ceramics have been reported to elute ions when subjected to nonneutral pH. However, the effect of surface treatments and thermomechanical aging on the ion elution of CAD-CAM ceramics is unclear. PURPOSE The purpose of this in vitro study was to compare the effect of surface treatment (glazed or polished) and thermomechanical aging on the ion elution of CAD-CAM materials before and after 2-body wear simulation. MATERIAL AND METHODS Specimens were prepared from 6 CAD-CAM materials-leucite (LC), feldspathic (FP), zirconia-reinforced lithium silicate (ZLS), lithium disilicate (LDS) glass-ceramics, polymer-infiltrated ceramic network (PICN), and zirconia (ZIR)-and divided into 2 groups according to the surface treatments (glazed or polished) (n=6). For baseline ion elution values, specimens were placed into polyethylene bottles containing deionized water (pH 7.4) that had been stored in an incubator for 168 hours at 37 °C. The eluted ions in the immersion solution were measured by using inductively coupled plasma-optic emission spectrophotometry. The specimens were then subjected to thermomechanical aging by using human enamel as an antagonist. After aging, the ion elution of the specimens was remeasured. Ion elution data before and after 2-body wear were analyzed by using the Mann-Whitney U test, while the effect of 2-body wear was assessed by using the Wilcoxon signed rank test (α=.05). RESULTS The presence of some ions varied depending on the material-surface treatment pair before (Al, As, B, Ba, Ca, K, Li, Mg, Na, P, and Zn) and after (Al, B, Ba, Ca, Co, Li, Mg, and P) 2-body wear. Polished materials had higher ion elution than the glazed materials before 2-body wear (P≤.041), except for LC (P and Zn) and PICN (Ca, Cu, and K) (P≤.009). After 2-body wear, polished LC (B and Ba), FP (Al, B, and Mg), ZLS (Al, Ba, Ca, and Li), ZIR (B and Ba), glazed PICN (Ca, Mg, and P), ZLS (P), and ZIR (Co) presented higher ion elution than their counterparts (P≤.041). The effect of 2-body wear on the ion elution of polished LC (Al, K), FP (Na), ZLS (Li), LDS (K, Na), PICN (Al, Na), ZIR (Na, Y), glazed LC (Na), FP (Ba, Na), ZLS (B, Ba, Y), LDS (Na), PICN (Y), and ZIR (Na) was nonsignificant (P≥.075). However, the elution of remaining ions showed a significant difference before and after 2-body wear (P≤.046). CONCLUSIONS The chemical stability of tested CAD-CAM materials was affected by the 2-body wear. Glazing led to a lower ion elution except for LDS and PICN. While polishing resulted in lower ion elution for PICN, both surface treatments resulted in similar ion elution for LDS.

Abstract
According to the recent studies, immunohistochemical subtypes of growth hormone (GH) secreting adenomas have been considered as a predictive factor in determining the clinical outcomes including biochemical, radiologic, and endocrine remission. In a 20 year-of time period, acromegaly patients who were treated and followed at the Endocrinology Department of our University Hospital were screened for the study. Of total 98 patients, 65 patients who had been operated by transsphenoidal surgery and having postoperative specimens were included. Postoperative specimens of the surgery of the patients were classified into 3 groups based on the histochemical characteristics (densely, sparsely, and mixed). Parasellar extensions of pituitary tumors were classified into the five grades according to Knosp classification. The patients were investigated and evaluated for postoperative clinical progress, remission rates, comorbidities regarding with the histopathological patterns. Of total 65 patients, 31 were classified as densely granulated (group 1), 32 were classified as sparsely granulated (group 2), and 2 patients were assessed as mixed granulated (group 3). There was no difference between groups for age and gender. Pre-treatment of adenoma size in all groups was correlated with each other and the frequency of macroadenoma (1 vs. 2, 77.4 vs. 84.3%) was higher in two groups. Although mean initial GH levels in group 1 was higher than the other groups (p=0.03), IGF1 levels (age and gender matched) were similar in each group. Adenomas in all groups demonstrated noninvasive radiological characteristics (Knosp grade 0-1-2). Ki-67 proliferation index of both groups (64.5 vs. 50%) was predominantly 1%. With a similar follow-up period, the endocrine remission rates (GH<1 μg/l) in groups were 64 vs. 69%, respectively. In conclusion, classification according to immunohistochemical subtypes of growth hormone secreting adenomas may not be a qualified parameter to evaluate patients with patterns of aggressiveness, clinical outcomes, or treatment response.

Abstract
Patients with diabetes have an increased risk of severe acute respiratory infections, and vaccination is their life-saving option. This study aimed to investigate the interest and knowledge of patients about influenza, pneumonia, and COVID-19(coronavirus disease 2019) vaccines. Materials. We handed out a questionnaire to patients with diabetes who were admitted to the endocrinology clinic between April and August 2021. The questionnaire collected information on demographic data, knowledge about respiratory tract disease vaccines, and hesitancy about vaccines. Results. Four hundred twenty-four patients (female = 256, male = 168) enrolled in the study. In this study, 148 (34.9%) participants were vaccinated against pneumonia, 155 (36.6%) against flu, and 312 (73.6%) against COVID-19. In addition, antivaccination sentiment was recorded in 8.7% of patients with diabetes. We found that participants in the study primarily rely on doctors as the source of information about vaccines (doctor (46.7%), nurse (1.2%), television (8.7%), friend/neighbour (8.7%), and others (2.6%)). The rate of vaccination was statistically higher than the presence of comorbid diseases. Conclusions. We examined the vaccine awareness of patients with diabetes and investigated factors affecting it. İt was determined that vaccination awareness is affected by many factors, especially comorbid diseases and educational status. The study showed that patients primarily relied on doctors as their source of information for vaccination. Doctor-centered vaccination promotion programmes can increase the rate of vaccination.

Could we assess the functional status, of hormone secreting, or non-secreting of the adrenal masses regarding their Magnetic Resonance Imaging (MRI) characteristics? Endocr Metab Immune Disord Drug Targets 2021; 22:650-657. [PMID: 34931972 DOI: 10.2174/1871530322666211220111637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 09/06/2021] [Accepted: 09/22/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Diagnostic imaging techniques including magnetic resonance imaging (MRI) should also perform on all patients with incidentalomas. However, there is a limited study whether the quantitative measurements (signal intensity index, adrenal to spleen ratio) in MRI could predict the functional status of adrenal adenomas. MATERIAL-METHOD Between 2015-2020; 404 patients (265 females, 139 males) with adrenal mass who were referred to the university hospital for further investigation were included. After detailed diagnostic hormonal evaluation, all patients underwent MRI 1.5 T device (Signa, GE Medical Systems; Milwaukee, USA). The signal intensities of the adrenal lesions on T2W images were qualitatively evaluated and noted as homogenous or heterogeneous in comparison with the liver signal intensity (SI). A chemical-shift SI index and chemical shift adrenal-to-spleen SI ratio were also calculated. RESULTS While 331(81.9%) of the patients had nonfunctional adrenal mass, the rest of them (n=73, 18.1%) were patients with functional (autonomous cortisol secretion-ACS, cushing syndrome-CS, pheochromocytoma, primary hyperaldosteronism-PA) adrenal masses. In phase vs phase values of patients with NFAI, Pheo(n=17), ACS (n=30), CS (n=11), and PA (n=15) were 474.04±126.7 vs 226.6±132.4, 495.3±182.8 vs 282.17±189.1, 445.2±134.8 vs 203.3±76.2, 506.8±126.5 vs 212.2±73.6 and 496.2±147.5 vs 246.6±102.1, respectively. Mean signal intensity index (SII) and adrenal to spleen ratio (ASR) of all groups (NFAI, Pheo, ACS, CS, PA) were 52.0±24.8 and 0.51, 44.9±22.5 and 0.55, 49.5±24.5 and 0.53, 56.2±16.4 and 0.43, 47.6±25.1 and 0.54, respectively. Based the current accepted measurements in the case of ASR and SII, all lesions were similar and shown as fat rich adenomas (p*= 0.552, p** = 0.45). CONCLUSION The quantitative assessment (SII, ASR) of intracellular lipids in an incidentally discovered adrenal tumour could only help distinguish adrenal masses in case of adenomas or non-adenomas As initial diagnostic evaluation, clinical and laboratory assessment ,to distinguish hormone secretion, should be taken in all patients with adrenal incidentalomas.

Abstract
Background According to neuroradiological findings, empty sella seems to be deprived of pituitary tissue in sella turcica. Changing size of the pituitary volume is closely related to the occurrence of primary empty sella. The aim of the study is to determine pituitary dysfunction in patients with partial or total primary empty sella and the significance of pituitary volume measurements in these patients. Methods This study was designed retrospectively. 67 patients (55 females, 12 males) diagnosed with primary empty sella syndrome between the years of 2015-2019 were included in the study. Patients were divided into two groups: partial (PES) and total (TES) empty sella by magnetic resonance imaging (MRI). Basal anterior pituitary and its hormones were assessed. We also included 26 healthy control subjects (19 females, 7 males) to compare the differences in pituitary volumes. Volumes were measured by using Osirix Dicom Viewer (Pixmeo SARL, Geneve, Swiss) in 3.0 Tesla scanner MRI. Results 82.1% (n=55) of all patients were PES and the others were (n=12) TES. Hypopituitarism, known as one or more pituitary hormones deficiency, was found in 12 patients (17.9%). While 9 of them had total PES, the others had partial PES. Secondary adrenal insufficiency and gonadotropin deficiency were more prevalent in patients with TES. Mean volume measurements of patients with TES, PES and healthy subjects were 0.23±0.17, 0.35±0.15, 0.54±0.17 cm3, respectively. Except for IGF1 values (p=0.026), there was not any significant correlation found between the anterior pituitary hormones and volume measurements. Conclusion Although volume measurement has helped in the diagnosis of pituitary empty sella (partial or total), it does not seem to have any significant correlation with pituitary secretory function.

Clinical Relevance and Immunohistochemical Patterns of Silent Pituitary Adenomas: 10 Years of Single-centre Experience. Curr Med Imaging 2021; 17:310-317. [PMID: 33357196 DOI: 10.2174/1573405616666201223125642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 11/11/2020] [Accepted: 11/13/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Silent pituitary adenomas are clinically non-functional (i.e., without clinically evident pituitary hormone production). INTRODUCTION The aim of this study was to investigate subjects with silent pituitary adenomas for possible variations in their clinical status. METHODS A total of 102 patients who had undergone surgery for pituitary adenoma and had been diagnosed with silent pituitary adenoma was included in the study. The patients' preoperative and postoperative hormonal parameters and magnetic resonance imaging (MRI) features were collected, and pathological specimens were re-evaluated. RESULTS Immunohistochemistry results of the 102 patients were as follows: hormone-negative adenomas (n=35) 35.5%; FSH+LH-positivity (n=32) 31.3%; ACTH-positivity (n=11) 10.7%; α-subunit- positivity (n= 9) 8.8%; prolactin-positivity (n=8) 7.8%; GH-positivity (n=6) 5.4%; and plurihormonal adenoma (n=1). The mean sizes of SGA, SGHA, and SCA were 28.0±12.7, 30.0±16.0, and 27.7±8.9mm (p>0.05), respectively. With the exception of silent gonadotroph adenomas (SGAs), female gender dominance was shown in patients with silent growth hormone adenoma (SGHA) and silent corticotroph adenoma (SCA). Although no clinical relevance was observed in relation to hormonal excess, preoperative GH (4.21±4.6, vs. 0.27±0.36 p=0.00) was slightly more elevated in SGHA than in GH-negative adenomas. Additionally, preoperative basal ACTH values (47.3±28.7 vs. 23.9±14.4, p=0.003) were also higher in SCA compared to the other types. Our findings revealed SCAs to be of more aggressive behaviour than SGHAs and SGAs due to invasiveness in radiological imaging, their elevated re-operation, and postoperative ACTH values. CONCLUSION Silent pituitary adenomas represent a challenging diagnostic tumour group. Careful initial evaluation of patients with pituitary adenomas should consider any mild signs and symptoms of functionality, particularly in cases of GH- and ACTH-secreting adenomas.

Possible role of the receptor of advanced glycation end products (RAGE) in the clinical course of prostate neoplasia in patients with and without type 2 diabetes mellitus. Int J Clin Pract 2021; 75:e13723. [PMID: 32957168 DOI: 10.1111/ijcp.13723] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 09/11/2020] [Indexed: 01/22/2023] Open
Abstract
AIM The expression of the cognate receptor of advanced glycation end products (RAGE) in malignant tissues of patients with type 2 diabetes has been suggested as a co-factor determining the clinical course and prognosis. We aimed to investigate the relationship between RAGE expression and clinicopathological features of prostate neoplasia. METHODS Tissue samples of 197 patients, 64 (24 patients with type 2 diabetes and 40 controls) with benign prostate hyperplasia (BPH) and 133 (71 patients with type 2 diabetes and 62 controls) with localised or metastatic prostate cancer (LPCa/MetPCa) were included in the study. The expression of RAGE in prostate specimens was studied immunohistochemically. RAGE scores were determined according to the extent of immunoreactivity and staining intensity. RESULTS RAGE expression in BPH group (patients with type 2 diabetes and controls) was negative. Patients with both LPCa and MetPCa had significantly higher scores than those with BPH (P < .001). The mean RAGE scores of patients with type 2 diabetes LPCa and MetPCa were 4.71 ± 3.14 and 4.97 ± 3.69. The mean scores of control LPCa and MetPCa were 1.52 ± 1.87 and 1.69 ± 1.58, respectively. The scores of patients with type 2 diabetes LPCa and MetPCa were significantly higher than those of control LPCa and MetPCa (P = .01 and P < .001, respectively). CONCLUSION We found higher RAGE expression levels in malignant prostate neoplasia than in BPH. As expected, patients with diabetes had higher scores than control patients. Disease progression and survival parameters were worse in patients with high RAGE levels. RAGE expression may be a useful biomarker for the diagnosis and prognosis of prostate cancer.

Abstract
PURPOSE Diabetic foot ulceration (DFU) is a common problem throughout the world and results in major economic consequences for the patients and country. We aim to describe the estimated cost of illness in patients with DFU in southern Turkey. METHODS A total of 148 (F=55, M=93) patients with DFU were included in this retrospective study. Patients characteristics, duration time of hospitalisations, biochemical parameters and the presence of diabetic retinopathy, nephropathy, neuropathy, coronary artery disease and peripheral artery disease were recorded from our database. The cost of each patient was recorded from financial affairs and the billing department unit of our hospital. RESULTS The average unit cost of each patient was £ 730.90±664.9. The major component in the total cost were medication (£ 258.8±360.9) and hospitalisation fees (£ 76.58±56.3). One hundred and fifteen (77.7%) of the patients had peripheral arterial diseases. While we could not determine significant correlations between the patients' demographical features (age, gender, p>0.05), biochemical parameters (plasma glucose, hemoglobin A1c % (HbA1c %)) and year of diagnoses with diabetes mellitus , the length of hospitalisation, presence of peripheral artery diseases and whether amputation (minor or major) was performed were significantly correlated with the total expenses. CONCLUSION The study revealed that the cost of DFU could show variability in relation to countries' level of development. We highlighted similar studies in other countries; the major factors of total expenses were length of hospitalisation, medication prescription and use of surgery.

Abstract
OBJECTIVES Prolactinoma is the most common cause of pituitary tumours. Current medical guidelines recommend dopamine agonists (cabergoline or bromocriptine) as the initial therapy for prolactinoma. However, surgical removal can also be considered in selected cases, such as patients with macroadenomas with local complications (bleeding or optic chiasm pressure) or those not responding to medical treatment. METHODS The present retrospective study included patients with prolactinomas (n=43; female, 24; male, 19) who were primarily managed with medical (n=32) or surgical (n=11) treatment. RESULTS Macroadenoma (n=29.67%) was commonly detected in both genders (female, 54%; male, 84%). Moreover, the mean pre-treatment prolactin levels were similar in both genders (female, 683.3 ± 1347 ng/mL; male, 685.4 ± 805 ng/mL; p=0.226). Surgically treated patients had a greater reduction in tumour size (27.7 ± 17.9 mm pre-treatment vs. 8.72 ± 14.2 mm post-treatment) than non-surgically treated ones (12.5 ± 7.5 mm pre-treatment vs. 4.1 ± 4.2 mm post-treatment; p=0.00). However, the decrease in prolactin levels was similar between the two patient groups (p=0.108). During the follow-up period (10.6 ± 7.0 years), the average cabergoline dose of the patients was 1.42 ± 1.47 mcg/week. CONCLUSIONS Although a surgical approach was considered for selected cases of prolactinoma, the average dose used for medical treatment was highly inadequate for the patients in the present study.

Abstract
BACKGROUND Hemoglobin A1c (HbA1c) is the major form of glycosylated hemoglobin. There are conflicting data on changes in HbA1c levels in patients with iron deficiency anemia (IDA). The present study aimed to investigate the effects of HbA1c levels in the presence of IDA, the effects of iron treatment on HbA1c levels, as well as the relationship between the severity of anemia and HbA1c levels in patients without diabetes. DESIGN AND METHODS A total of 263 patients without diabetes mellitus (DM) who were admitted to Cukurova University, Faculty of Medicine, Department of Endocrinology and Hematology or who were followed up in this clinic and diagnosed as having IDA were included in the study. A total of 131 patients had IDA. The control group comprised 132 age-matched and sex-matched healthy individuals. RESULTS The mean HbA1c level was significantly lower in the group with IDA (5.4%) than in the healthy control group (5.9%; p < 0.05). When the patients were divided into three groups according to the severity of anemia through Hb levels, HbA1c levels were observed to decrease as the severity of the anemia increased (5.5%, 5.4%, and 5%, respectively; p > 0.05). The HbA1c levels of the patients with IDA were higher after iron therapy (from 5.4 ± 0.5 to 5.5 ± 0.3; p = 0.057). The mean hemoglobin (Hb), hematocrit (Hct), mean cell volume (MCV), mean corpusculer hemoglobin (MCH), and ferritin values also increased after iron therapy (p < 0.05). CONCLUSION The study results showed that IDA was associated with low HbA1c levels, and increased after iron therapy. Based on the study findings, it is necessary to consider the possible effects of IDA on HbA1c levels.

Abstract
To assess the demographic characteristics and hormonal status of patients who presented to our clinic with pituitary adenoma and to demonstrate the presence, prevalence, and relationship of metabolic syndrome parameters in these patients. The study included 303 patients with known or newly diagnosed pituitary adenoma and 52 age- and sex-matched healthy controls. The patients were classified into 3 groups; acromegaly (ACRO) (n=54),prolactinoma (PRLoma) (n=163), and non-functional adenoma (NFA) (n=86). in 55.6% (n=172) and 52% (n=163) of the patients, respectively. The waist circumference of all patients (p<0.001) and body mass index (BMI) of patients with PRLoma (p=0.03) and ACRO (p<0.001) were found to be significantly higher than in the controls. The HbA1c, insulin and HOMA-IR values were significantly higher in the ACRO and PRLoma groups, whereas the insulin and HOMA-IR values were significantly higher in the NFA group compared with the control group (p<0.001 and p<0.001, respectively). When the 3 patient groups were compared, waist circumference and BMI were significantly higher in the ACRO group than in the PRLoma group (p=0.04 and p=0.03, respectively). In patients developing pituitary failure after treatment, age, waist circumference, plasma glucose, low-density lipoproteins and triglyceride values were significantly increased when compared with those without pituitary failure after treatment (p<0.001). In our study, it was found that there was increased metabolic and cardiovascular risk in functional pituitary adenoma and NFA.

Anemia in Patients with Diabetic Foot Ulcer: Effects on Diabetic Microvascular Complications and Related Conditions. Endocr Metab Immune Disord Drug Targets 2019; 19:985-990. [DOI: 10.2174/1871530319666190111121913] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Revised: 11/07/2018] [Accepted: 01/02/2019] [Indexed: 01/13/2023]
Abstract
Objective:
We aimed to investigate the etiology and prevalence of anemia in patients with
diabetic foot ulcers and the relationship between both microvascular complications and related
conditions and anemia.
Methods:
We retrospectively collected and evaluated the data of 225 patients with diabetic foot ulcer
followed at our clinic. The demographic characteristics of the patients were analyzed. Complete blood
count for those with anemia, serum iron, iron-binding capacity, ferritin, transferrin saturation index,
vitamin B12, folic acid and thin blood film were performed. The diabetic microvascular complications
and related conditions such as osteomyelitis, peripheral artery disease, and amputations were also determined.
IBM SPSS Statistics Version 20.0 package software was used for the statistical analysis of
the data.
Results:
Of 225 patients were 67 (29%) female and 158 (70.2%) male. The mean age of the patients
was 62 ± 10.5 years (30-87). Duration of diabetes was 16.2 ± 6.7 years (2-31). Of the 225 patients, 41
had hypertension, 14 had chronic kidney failure, and 34 had coronary artery disease. Anemia was
found in 192 (85.3%) of the 225 patients. Of 192, 126 (56%) had iron deficiency anemia, 50 had folate-
deficiency anemia, and the remaining 16 had anemia of chronic disease. Iron deficiency anemia
was significantly found to be higher in women. There was no significant difference between patients
with and without anemia in terms of diabetic microvascular complications (neuropathy, retinopathy,
nephropathy) and the related conditions.
Conclusion:
We have found that the most common cause of anemia was iron deficiency anemia.
However, in our study, the prevalences of microvascular complications did not vary between patients
with and without anemia. On the other hand, since all of our patients are having DFU and the high
rates of microvascular complications and correlation with the presence of anemia could not be clearly
portrayed.

Diagnostic efficacy of 18F-FDG PET/CT in patients with adrenal incidentaloma. Endocr Connect 2019; 8:838-845.

Abstract
BACKGROUND The management of adrenal incidentaloma is still a challenge with respect to determining its functionality (hormone secretion) and malignancy. In this light, we performed 18F-FDG PET/CT scan to assess the SUVmax values in different adrenal masses including Cushing syndrome, pheochromocytoma, primary hyperaldosteronism and non-functional adrenal adenomas. METHODS Total 109 (73 F, 36 M) patients with adrenal mass (incidentaloma), mean age of 53.3 ± 10.2 years (range, 24-70) were screened by 18F-FDG PET/CT. Data of 18F-FDG PET/CT imaging of the patients were assessed by the same specialist. Adrenal masses were identified according to the calculated standardized uptake values (SUVs). Clinical examination, 24-h urine cortisol, catecholamine metabolites, 1-mg dexamethasone suppression test, aldosterone/renin ratio and serum electrolytes were analyzed. RESULTS Based on the clinical and hormonal evaluations, there were 100 patients with non-functional adrenal mass, four with cortisol-secreting, four with pheochromocytomas and one with aldosterone-secreting adenoma. Mean adrenal mass diameter of 109 patients was 2.1 ± 4.3 (range, 1-6.5 cm). The 18F-FDG PET/CT imaging of the patients revealed that lower SUVmax values were found in non-functional adrenal masses (SUVmax 3.2) when compared to the functional adrenal masses including four with cortisol-secreting adenoma (SUVmax 10.1); four with pheochromcytoma (SUVmax 8.7) and one with aldosterone-secreting adenomas (SUVmax 3.30). Cortisol-secreting (Cushing syndrome) adrenal masses showed the highest SUVmax value (10.1), and a cut-off SUVmax of 4.135 was found with an 84.6% sensitivity and 75.6% specificity cortisol-secreting adrenal adenoma. CONCLUSIONS Consistent with the similar studies, non-functional adrenal adenomas typically do not show increased FDG uptake and a certain form of functional adenoma could present various FDG uptake in FDG PET/CT. Especially functional adrenal adenomas (cortisol secreting was the highest) showed increased FDG uptake in comparison to the non-functional adrenal masses. Therefore, setting a specific SUVmax value in the differentiation of malignant adrenal lesion from the benign one is risky and further studies, including a high number of functional adrenal mass are needed.

Abstract
OBJECTIVES The objectives of the study were to analyze the clinical characteristic of diabetic cheiroarthropathy (DCA) in patients with type 1 diabetes mellitus (DM), type 2 DM, and prediabetes and to evaluate the frequency of DCA among groups. METHOD The cross-sectional study was conducted at the Division of Endocrinology and Metabolism outpatient clinic over a 14-month period. A total of 239 patients (160 female, 79 male), who had type 1 DM, type 2 DM, and prediabetes, were enrolled. The demographics, clinical variables, and laboratory outcomes were recorded. Diabetic cheiroarthropathy was defined according to physical examination. The functional disability of patients with DCA was assessed by the self-administered questionnaire (disabilities of the arm, shoulder and hand-DASH). RESULTS Diabetic cheiroarthropathy was determined in 35.1% of all patients. The frequency of DCA was higher in patients with prediabetes (x2 = 0.009, post hoc power = 0.794). According to the logistic regression analysis, prediabetes (OR = 4.52, 95% CI 2.16-9.47, p < 0.001), presence of polyneuropathy (OR = 3.82, 95% CI 1.61-9.07, p = 0.002), and fasting glucose level (OR = 1.01, 95% CI 1.00-1.01, p = 0.004) found as the most effective risk factors in determining DCA. DASH disability scores were significantly higher in prediabetic patients than that in type 2 DM group (p = 0.021). CONCLUSION High frequency of DCA and impaired hand function are observed in prediabetic patients. Musculoskeletal manifestations can emerge as an early sign of diabetic status. Also, people who suffer from hand involvement should be examined for diabetes along with rheumatologic diseases.

Abstract
OBJECTIVE Adrenal incidentalomas are diagnosed incidentally during radiological screenings and require endocrinological investigations for hormonal activity and malignancy. In certain studies, it has been reported that non-functional incidentalomas can be associated with high adipocytokines levels affecting the insulin resistance just like the adipose tissue with metabolic syndrome. Here, we studied serum adipocytokine levels including leptin, resistin, visfatin, omentin 1 and adiponectin in subjects with non-functional adrenal incidentaloma. METHODS Seventy-seven (77) patients (Female 57; Male 20) with non-functional adrenal incidentaloma (NFAI) were enrolled in the study. All patients' past medical history, physical examination including Body Mass Index (BMI) and waist circumference were performed. The patients' demographic, radiologic, hormonal and biochemical parameters were recorded. To compare the parameters, a control group (CG) (n=30) was formed from healthy volunteers. Both groups were matched for age, gender, waist circumference and BMI. Serum adipocytokines including leptin, resistin, visfatin, omentin 1 and adiponectin were measured quantitatively by ELISA. Fasting plasma glucose, insulin, sodium, potassium, cortisol, adrenocorticotropic hormone (ACTH), lipid profiles, and dehidroepiandrostenedion sulphate (DHEAS) were measured. RESULTS Mean age of the patients was 52.2±10.4 years. BMI and waist circumference of NFAI patients were 26.2±3.28 kg/m2 and 90.2 ±7.5cm, respectively. The mean age of the control group was 48.0±8.16. BMI and waist circumference values for the control group were 25.3±3.5 kg/m2 and 88.3±9.6 cm, respectively. When both groups were compared for age, gender, BMI and waist circumference were non-significant (p>0.05). Serum fasting insulin, total cholesterol, LDL, triglyceride levels of the NFAI group were significantly higher than CG (p<0.05). The insulin resistance index (HOMAIR) values of the NFAI subjects were found to be higher than CG (2.5±1.37, 1.1±0.3 p=0.00). Resistin level of NFAI group was also found to be higher than CG [286.6 ng/L vs. 197 ng/L; (P=0,00)], respectively. Leptin levels of NFAI were significantly higher than CG [441.1 ng/mL vs. 186.5 ng/mL; (P=0.00)] respectively. Adiponectin levels were significantly reduced in the NFAI group than in the CG [10.7 mg/L vs. 30.8 mg/L; (P=0.00)]. Comparision of visfatin and omentin levels was nonsignificant. CONCLUSION In this study on subjects with non-functional adrenal incidentaloma, we found not only significantly decreased serum adiponectin levels but also increased leptin, resistin levels as well as dyslipidemia, hypertension and high insulin resistance index. All of which could affect insulin resistance and cardiovascular risk factors. The underlying mechanisms of these findings are unknown, hence further studies are needed.

Abstract
BACKGROUND Adrenal incidentalomas are adrenal masses that are discovered by imaging tests performed for other reasons. AIMS In this retrospective study, we analysed 229 Turkish patients with adrenal masses and who presented with or without complaints. STUDY DESIGN Descriptive retrospective study and review of the literature. METHODS This study conducted a retrospective review of 229 patients with adrenal incidentalomas that were referred to Cukurova University Hospital's endocrinological department between 2009 and 2014. We reviewed detailed patient histories, physical examination findings, and symptoms and signs related to hormonal hypersecretion or malignant neoplasm and recorded clinical indications for performing diagnostic radiological imaging. The statistical analysis of data was performed using SPSS-19 software. RESULTS Of the 229 patients reviewed, 195 (85.2%) had non-functional, benign adrenal adenomas, and 34 (14.8%) had functional lesions. Among those with functional lesions, 8 (3.5%) had lesions that secreted excess cortisol, 11 (4.8%) had lesions that secreted aldosterone, and 15 (6.6%) had lesions that secreted catecholamines. Eighty-four patients included in the study (36.8%) underwent adrenalectomy; in 14 of these cases, the adrenalectomy was performed before surgical treatment criteria occurred. The most frequent pathologic diagnosis was adrenal cortical neoplasia (n = 38); 32 of these patients had adenomas (Weiss <4 criteria), and 6 had carcinomas (Weiss >4 criteria). Other patient diagnoses included benign pheochromocytoma (n = 13), pseudocyst (n = 12), metastasis (n = 10), haemorrhage (n = 3), necrosis (n = 1), hyperplasia (n = 2), and other (n = 5). CONCLUSIONS Detailed endocrinological and radiological assessments of the mass nature and hormone status are necessary in cases of adrenal incidentaloma. Appropriate surgical treatment or periodic follow-up must be determined based on the assessment results.

Abstract
Spontaneous calcaneal fractures in diabetic patients without obvious trauma may occur, sometimes accompanying diabetic foot ulcers. In the current study we report four cases who were hospitalized for diabetic foot ulcer with concomitant calcaneal fractures. There were four diabetic patients (one type 1 and three type 2) who registered with diabetic foot ulcers with coexisting calcaneal fractures, all of which were classified as Type A according to Essex Lopresti Calcaneal Fracture Classification. Two of the patients with renal failure were in a routine dialysis program, as well as vascular compromise and osteomyelitis in all of the patients. The diabetic foot ulcer of the 61 years old osteoporotic female patient healed with local debridement, vacuum assisted closure and then epidermal growth factor while the calcaneal fracture was then followed by elastic bandage. In two patients could not prevent progression of diabetic foot ulcers and calcaneal fractures to consequent below-knee amputation. The only patient with type 1 diabetes mellitus improved with antibiotic therapy and split thickness skin grafting, while the calcaneal fracture did not heal. In the current study we aimed to emphasize the spontaneous calcaneal fractures as possible co-existing pathologies in patients with diabetic foot ulcers. After all the medical treatment, amputation below knee had to be performed in 2 patients. It should be noted that other accompanying conditions such as impaired peripheral circulation, osteomyelitis, chronic renal failure, and maybe osteoporosis is a challenge of the recovery of calcaneal fractures and accelerate the progress to amputation in diabetic patients.

Abstract
OBJECTIVE Impaired cellular immunity and reduced phagocytic function of polymorphonuclear leukocytes facilitate the development of skin fungal and bacterial infections due to uncontrolled hyperglycemia in diabetic patients. In our study, we aimed to assess onychomycosis and/or tinea pedis frequency in diabetic patients, and effects on the development of chronic complications, particularly foot ulcer. METHODS We included 227 diabetic patients in the study. Forty-three patients had diabetic foot ulcer. We screened and recorded demographic characteristics, HbA1c levels of patients, and presence of complications We examined patients dermatologically, and collected samples by scalpel from skin between toes, and from sole, toe nail, and area surrounding nails from suspected to have fungal infection. RESULTS Native positivity between toes was higher in men compared to women (p<0.05). We obtained significant relation between HbA1c elevation and native positivity between toes (p<0.05). Fungal infection between toes, at sole and toe nail significantly increased in patients with diabetic foot ulcer compared to patients without diabetic foot ulcer (p<0.05). Moreover, native positivity in patients with diabetic foot ulcer correlated with presence of fungal infection examination findings (p<0.05). CONCLUSION Fungal infections were more frequently observed in the presence of poor glycemic control and peripheral vascular disease in diabetic patients in compliance with the literature, and the presence of fungal infection may also responsible for the development of foot ulcers.

Abstract
Background Our purpose was to show the association of adrenal incidentaloma and metabolic syndrome in consideration of the studies and to detect the increase in the carotid intima-media thickness which is regarded as the precessor of atherosclerosis. Material/Methods Eighty-one patients who were diagnosed with adrenal mass were included in the study. Hormonal evaluation, insulin rezistance measurement with the HOMA-IR and 1-mg DST were performed of all patients. The patients were classified as follows: mass size <3 cm (K1) and mass size of at least 3 cm (K2). Echocardiography and carotid intima-media thickness of the patients were measured using B-mode ultrasound. Thirty-three healthy individuals were enrolled as the control group. Results Mass size of 64.19% K1, while mass size of the remainder (35.81%) K2 was calculated. Five of the patients with adrenal mass were detected to have subclinical Cushing syndrome. The remaining 76 patients were accepted as nonfunctional. It was seen with regard to metabolic and biochemical parameters that plasma glucose (p=0.01), insulin (p=0.00) and triglyceride (p=0.012) values of all patients were significantly high compared to those of the control group. It was detected that measured heart rate (p=0.00), end-diastolic diameter (p=0.02), end-systolic diameter (p=0.014) and carotid intima-media thickness (p=0.00) values of the patients with adrenal mass were significantly higher than those of the healthy control group. Conclusions We found that the increased insulin resistance, increased risk of cardiovascular disease with the increase in the thickness of carotid intima-media and diastolic disfunction parameters, although the patients with adrenal incidentaloma are nonfunctional.

Abstract
OBJECTIVE The objective of this study is to evaluate the impact of sequential telephonic interviews on treatment persistence and daily adherence to insulin injections among insulin-naïve type 2 diabetes patients initiated on different insulin regimens in a 3-month period. METHODS A total of 1,456 insulin-naïve patients with type 2 diabetes (mean [standard deviation, SD] age: 56.0 [12.0] years, 49.1% were females) initiated on insulin therapy and consecutively randomized to sequential (n=733) and single (n=723) telephonic interview groups were included. Data on insulin treatment and self-reported blood glucose values were obtained via telephone interview. Logistic regression analysis was performed for factors predicting increased likelihood of persistence and skipping an injection. RESULTS Overall, 76.8% patients (83.2% in sequential vs 70.3% in single interview group, (P<0.001) remained on insulin treatment at the third month. Significantly higher rate for skipping doses was noted in basal bolus than in other regimens (27.0% vs 15.0% for premixed and 15.8% basal insulin, respectively, P<0.0001). Logistic regression analysis revealed sequential telephonic interview (odds ratio [OR], 1.531; 95% confidence interval [CI], 1.093-2.143; P=0.013), higher hemoglobin A1c levels (OR, 1.090; 95% CI, 0.999-1.189; P=0.049), and less negative appraisal of insulin therapy as significant predictors of higher persistence. Basal bolus regimen (OR, 1.583; 95% CI, 1.011-2.479; P=0.045) and higher hemoglobin A1c levels (OR, 1.114; 95% CI, 1.028-1.207; P=0.008) were the significant predictors of increased likelihood of skipping an injection. CONCLUSION Our findings revealed positive influence of sequential telephonic interview, although including no intervention in treatment, on achieving better treatment persistence in type 2 diabetes patients initiating insulin.

Abstract
Background Primary hyperparathyroidism is one of the most common causes of hypercalcemia. Inherited forms of primary hyperparathyroidism like Multiple Endocrine Neoplasia Type 1, Multiple Endocrine Neoplasia Type 2a, Hyperparathyroidism-Jaw Tumor Syndrome or isolated familial tumors are not common for our population. Results We present a case of primary hyperparathyroidism in a 38-year-old Turkish man with hyperaldosteronism (Conn’s syndrome). Conclusion Genetic studies could not reveal any mutation. We could not identify any inherit form of the diseases. We wanted the first-line relatives examination of the suspected gene mutation, but they refused.

Abstract
BACKGROUND This study aimed to report the clinical and outcome data from a large cohort of patients diagnosed with acromegaly and treated at our institution over a 20-year period. METHODS Sixty-two acromegaly patients (32 women and 30 men) treated and monitored at the endocrinology polyclinic between 1984 and 2013 were enrolled in this retrospective study. Clinical features and patients' treatment outcomes were evaluated. A level of growth hormone (GH) of <2.5 ng/ml was considered as the criterion for remission, and the normal insulin-like growth factor (IGF) range was based on gender and age. RESULTS The mean age at the time of diagnosis was 38.8 ± 1.4 years, the time to diagnosis was 4.5 ± 0.3 years, and the follow-up duration was 7.3 ± 0.8 years. Among patients' symptoms, growth in hands and feet and typical facial dysmorphism were the most prominent (92%). The number of patients with diabetes mellitus, hypertension and hyperprolactinemia were 22 (35%), 13 (21%) and 13 (21%), respectively. Microadenomas and macroadenomas were found in eight and 54 patients, respectively. A significant correlation was found between the initial tumor diameters and GH levels (p = 0.002). The mean GH and IGF-1 levels were 39.18 ± 6.1 ng/ml and 993.5 ± 79 ng/ml, respectively. Visual field defect was found in 16 patients (32%). Thirty-one patients were treated by transsphenoidal surgery. Four of these were cured, 10 patients developed postoperative anterior pituitary hormone deficiency, and one patient developed diabetes insipidus. Twenty patients were treated by transcranial surgery, of which two were cured, while 17 patients developed postoperative anterior pituitary hormone deficiency. In total, five of the patients who were not cured after surgery were given conventional radiotherapy, of which two were cured. Four of 15 patients, on whom Gamma Knife radiosurgery was performed, were cured. Biochemical remission was achieved in 32 of 52 patients who received octreotide treatment, and in two of five patients who received lanreotide treatment. CONCLUSIONS The rate of surgical success in our patients was found to be low. This could be explained by an absence of experienced pituitary surgical centers or surgeons in our region, and the fact that most patients presented late at the macroadenoma stage.

Abstract
OBJECTIVES The objective of this prospective, controlled clinical study was to determine the outcomes of dental implant therapy with staged guided bone regeneration procedures in patients with type 2 diabetes. PATIENTS AND METHODS Twenty-four patients were included in the study. Half of the patients were diagnosed with type 2 diabetes mellitus (group 1) while the other half (group 2) of the patients consisted of patients without diabetes. The edentulous maxillary anterior/premolar regions with sufficient vertical height but inadequate horizontal width were treated with staged guided bone regeneration technique and with one or two implant-supported fixed restorations. The patients were followed up at least for 12 months. The parameters that were evaluated were radiographic evaluations on CBCT images and periapical radiographs, histomorphometric analysis, resonance frequency analysis (RFA) and wound-healing parameters. The data were analyzed statistically. RESULTS A total of 43 implants were placed in 24 patients (22 implants in group 1 and 21 implants in group 2). The survival rates of implants were 100% for both groups. The success rate of implants was 95% for group 1 and 100% for group 2. None of the parameters including CBCT findings, RFA values, success rates and wound-healing scores showed a significant difference between the two groups. CONCLUSION Staged guided bone regeneration is a feasible augmentation procedure for the treatment of horizontal bone deficiencies of the maxillary anterior/premolar regions in well-controlled type 2 diabetic patients.

Abstract
Previous studies have suggested an influence of vitamin D receptor alleles on bone metabolism and on susceptibility to type 1 diabetes mellitus in different ethnic populations. We aimed to investigate the distribution of vitamin D receptor (VDR) alleles in relation to biochemical bone turnover parameters and bone densitometry measurements in a group of Turkish type 1 diabetic patients. One hundred and seventeen patients (M/F 57/60, 27.6 ± 7.3 y duration of diabetes 8.1 ± 6.3 y) and 134 healthy controls (M/F 61/73, 26.2 ± 5.3 y) were included in the study. Bone mineral density (BMD) was evaluated by dual-energy X-ray absorptiometry (DEXA). The vitamin D receptor gene (VDR) polymorphisms FokI, Bsm1, Apa1, and Taq1 were examined using a PCR-based restriction analysis. Serum levels of calcium, phosphor osteocalcin, intact parathyroid hormone, and C telopeptide were measured. Vitamin D receptor Bsm1 Fok1, Apa1, and Taq1 genotype distributions were not different between patient with diabetes and control groups. BMD was 0.77 ± 0.2 g/cm(2) vs. 0.97 ± 0.2 g/cm(2) (P = 0.0001) for the femur, 1.0 ± 0.1 g/cm(2) vs. 1.13 ± 0.1 g/cm(2) (P = 0.001) for type 1 diabetic patients and controls. Bone turnover markers were significantly lower in type 1 diabetic group. BMD measurements and bone metabolic markers were not different between the genotypes in either the patient with diabetes or the controls. The VDR gene polymorphisms, Bsm1, Fok 1, Apa1, and Taq1 showed no influence on bone metabolism in our group of type 1 diabetic patients.

Abstract
Charcot-Marie-Tooth (CMT) disease is a hereditary demyelinating peripheral neuropathy, and CMT Type 1A is the most common form. In most cases, CMT1A is usually caused by duplication at chromosome 17p11.2-12. Type 2 diabetes mellitus (Type 2 DM) is a common metabolic disorder, characterized by chronic hyperglycemia that can be associated with micro- and/or macrovascular complications. Only a few studies reported CMT1A duplication in association with Type 2 DM. This article explores the characteristics of a large family of 69 members with respect to CMT1A and Type 2 DM. CMT1A was detected in 28 of them. Molecular genetic study was performed in 22, and duplication was detected in all of them. Six of the 22 members with CMT1A also had Type 2 DM based on the American Diabetes Association diagnostic criteria. Association of these two conditions may be coincidental; however, the occurrence of these two diseases in this large family may also suggest a genetic basis. More extensive reports and further investigations of such families having this combination will certainly provide a better understanding of this link.

Abstract
In this study, we investigated the safety and toxicity of isoniazid (INH) intervention therapy to the patients with latent tuberculosis who were given tumor necrosis factor alpha (TNFalpha) for the treatment of their rheumatologic diseases. In this prospective clinical study, we enrolled 86 patients receiving anti-TNFalpha therapy for their rheumatologic diseases between April 2005 and September 2006. Of all the subjects, 45 had rheumatoid arthritis, 36 had ankylosing spondylitis, and 5 had psoriatic arthritis. In addition to anti-TNFalpha therapy, 60 of the 86 patients were given INH intervention for revealed latent tuberculosis. INH at a dosage of 300 mg daily was given for 9 months. Hepatotoxicity due to the INH therapy was considered when the serum alanine aminotransferase (ALT) and/or aspartate aminotransaminase (AST) levels showed at least threefold increase with respect to their baseline serum levels. Serum ALT and AST levels were measured by enzymatic colorimetric method in fasting peripheral blood samples at 0 (baseline), 1, 2, 3, 6, and 9 months. Of 86 patients, 47 (54.7%) were women (mean age+/-SD, 44.1 +/- 10.9 years) and 39 (45.3%) were men (38.8 +/- 10.1 years). Except five patients (8.3%), liver toxicity due to the INH therapy was not encountered among the patients, and after temporarily discontinuing the INH therapy of these five subjects, serum transaminase levels returned to the normal ranges. No hepatotoxicity was observed in the non-INH group. However, there was no statistical significance between INH-treated and non-INH-treated group (p = 0.317). In addition, none of the 86 patients developed active tuberculosis infection during the treatment period. In conclusion, for those patients who were assigned to the TNFalpha treatment for their rheumatologic disorders and carrying risk for latent tuberculosis, INH intervention therapy was found to be safe and efficacious.
