ACTA ENDOCRINOLOGICA (BUC)

Context. Red cell distribution width (RDW) has been associated with type 2 diabetes (T2DM), however data in relation to diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar non-ketotic acidosis (HONK) remains unclear. Objective. The aim of this study was to evaluate the association between RDW, MCV, and RDW/MVC values and acute complications in T2DM. Patients and Methods. RDW was measured in 90 T2DM patients (30 DKA, 30 HONK and 30 T2DM without acute complications). Clinical variables were analyzed by One –Way ANOVA, Kruskal-Wallis and Pearson analysis with SPSS software. Diagnostic screening tests and ROC curve analysis determined the cut-off point of MCV,RDW and RDW/MCV values. Results. DKA patients had higher levels of plasma glucose (524.20±201.43mg/dL, p<0.001), HbA1c (10.73±2.29%, p<0.001), osmotic pressure (310.32 mosm/L, p<0.001), RDW (14.61±1.75g/L, p<0.01), and the RDW/MCV ratio (0.17±0.04%, p<0.01), compared to HONK patients. RDW/MCV cut-off value was 0.15 with 90% sensitivity 50% specifity these values for only MCV were 76.67%-70%, for only RDW were 76.67%- 63.33% respectively. The area under curve values for the ability to reflect DKA for RDW and the RDW/MCV ratio were 0.708 and 0.766, respectively (p<0.001). Conclusions. RDW and RDW/MCV ratio were found associated with DKA and valuable in predicting DKA. However these parameters were not valuable in predicting HONK.

Evans syndrome is a rare combination of autoimmune hemolytic anemia and immune thrombocytopenia. Evans syndrome in cases of Graves’ disease is extremely rare. The coexistence of these autoimmune diseases suggests that they may share a common pathogenic pathway. The case here presented is of a 36-year old female patient who was admitted for anemia and thrombocytopenia and was diagnosed with Evans syndrome associated with Graves’ disease, and was then treated with methimazole and methylprednisolone (MPSL). During follow-up, MPSL was discontinued gradually over the course of two months. Interestingly, while Evans syndrome is characterized by frequent relapses, this patient has been in remission of Evans syndrome for approximately 1 year without MPSL therapy. The remission of Evans syndrome associated with Graves’ disease in the absence of immunosuppressive therapy suggests that these 2 diseases have a common pathogenetic mechanism.

Objective. TSH-secreting pituitary adenomas (TSH-omas) are very rare disorders. This report describes the diagnosis and treatment of a thyroid-stimulating hormonesecreting ectopic pituitary adenoma in the nasopharyngeal region. Subjects and Methods. We report a 37-year-old male patient with thyroid-stimulating hormone-secreting ectopic pituitary adenoma in nasopharyngeal region. Results. A patient suffering from sweating, palpitations, dizziness and abnormality in thyroid tests was referred to our clinic. Thyroid function tests showed high basal levels of free thyroxine (FT4), free tri-iodothyronine (FT3), and serum TSH. TRH stimulation test results indicated blunted response. Scintigraphy showed increased radionuclide uptake (iodine-123), and a thyroid ultrasound scan revealed diffuse enlargement of the thyroid gland. A pituitary MRI indicated a normal pituitary. However, MRI showed a mass in the nasopharynx that was confirmed with endoscopy. Endoscopic total endonasal resection was done and the mass was removed. The pathology reported a TSHsecreting pituitary adenoma. Conclusion. In this report, an identified case of thyroid-stimulating hormone-secreting ectopic pituitary adenoma in nasopharyngeal region is reported and it is the only tenth case in the literature indicated in the nasopharyngeal region. Ectopic TSH-omas should be considered during inappropriate secretion of TSH as a candidate cause to enable correct diagnosis and improve the treatment of patients.

Objective. This study aims to investigate the effect of job characteristics and protective factors on burnout, one of the common medical staff issues. So far, little attention has been paid to testing protective factors' role on medical staff exhaustion. Design. Using a correlation design, these constructs were tested on a sample of 221 participants, doctors, and nurses. Main Outcome. The present study revealed protective factors power in predicting burnout, over job characteristics, and the moderation effect of role-playing in the medical care unit and clinical department. Measures. For assessing burnout were used a Romanian translated version of the Maslach Burnout Inventory – General Survey (MBI). Results. Protective factors like physical activities, vacation, and hours spent with family introduced an explanatory model and had a predictive validity over job characteristics in predicting medical staff's burnout. Finally, the effect of physical activities on burnout was moderated both by the role played in the medical care unit and clinical department, while the effect of time served in other medical institutions was moderated only by the role played in the medical care unit. Conclusion. These results provide guidance for better burnout programs interventions, which are addressed to medical healthcare experts.

Background. Mosaic karyotype 45,X/46,XY related mixed gonadal dysgenesis. Aim. To report a case of mosaic karyotype and petroclival meningioma. Methods. Presentation of a clinical case with comments. Results. The case of a 37-year-old woman mosaic karyotype - 45,X/46,XY, infertility, virilisation, Turner syndrome-like phenotype, primary amenorrhea, the absence of labia majora and petroclival meningioma. Concentrations of dehydroepiandrosterone sulphate (DHEAS), testosterone, luteinizing hormone (LH) and follicular stimulating hormone (FSH) were increased indicating hypergonadotropic hypogonadism. Low and high dose dexamethasone suppression tests demonstrated incomplete suppression of DHEAS concentration without connection between pulses of LH/FSH and DHEAS. Response to adrenocorticotropic hormone (ACTH) was normal. The morning/evening concentration ratio of DHEAS was very low in comparison with cortisol, ACTH and testosterone. Head magnetic resonance imaging (MRI) demonstrated petroclival meningioma without any adrenal or ovary abnormality. Menstruation started after treatment with 2 mg of estradiol. At control visit 1.5 years later she had no complaints. MRI did not demonstrate any signs of tumour progression. Conclusions. The main lesson learned from this case is that in searching the DHEAS secreting tumours one can find unusual cases with sustained high DHEAS and lack of confirmations of polycystic ovary syndrome, adrenal or ovary tumours using available ultrasound, CT and MRI.

Introduction. Subacute thyroiditis (SAT) is a self-limiting thyroid disease associated with a triphasic clinical direction of hyperthyroidism, hypothyroidism and back to normal thyroid function. Precise etiology of this clinical condition is unknown. Generally diagnosis is based on clinical-laboratory parameters. Considerable cases of SAT develop after several types of viral infections. We herein describe two cases that developed SAT after dental extraction. Cases. Two-female patients in the forties ages experienced fever and neck pain after dental extraction. The patients presented elevated sedimentation rates and SAT symptoms. After clinical diagnosis and therapy administration, symptoms resolved after one week. Conclusion. We have presented two cases experiencing SAT after dental extraction. The management and possible association with current literature were discussed.

Objective. We aimed to reach a diagnosis for patients with pituitary failure (PF) with more detailed multifaceted examination, to obtain new gains in this way and to apply this experience to our future patients. Patients and Method. The study included 72 patients with pituitary failure diagnosis. Patients were divided into two groups of 32 female patients with Sheehan syndrome (SS) and 40 non-Sheehan syndrome patients (20 female and 20 male). Results. The mean age of the 32 patients with Sheehan syndrome was 56.1±11.7 years with mean disease duration 20.3±8.3 years and mean age at disease onset 34.3±7.6 years. For the 40 non-SS pituitary failure patients mean age was 46.5±16.6 years, mean disease duration was 4.7±5.1 years and mean age at disease onset was 41.8±18.2 years. The prolactin response (PRL) on the TRH test was found to be significantly lower in SS patients compared to non-SS patients(p<0.05). Both patient groups had low basal pituitary hormones, with mean PRL level in SS patients 4.9±4.0 ng/mL which was significantly low compared to non-SS patients with 36.8±84.7 ng/mL(p=0.022). Conclusion. Pituitary failure patients may present with a broad range of clinical symptoms and findings. Early diagnosis and timely replacement treatment have vital importance for SS patients.

Context. Sodium-glucose co-transporter 2 inhibitors (SGLT2-I) are a new class of oral antidiabetic drugs. Objective. Side effects of drugs are frequently encountered with increasing use in clinical practice. Design/Subjects and Methods. We present a case with an unidentified body odor that has not been described yet in the literature as an adverse effect of SGLT2-I. Results. A 49-year-old female patient with Type 2 DM was applied to our clinic for routine control. She had been receiving sitagliptin/metformin 50/1000 mg b.i.d. Her fasting plasma glucose was 160 mg/dL and HbA1c was 8%. Empagliflozin 10 mg/day was added to therapy. The patient noticed that two weeks after starting empagliflozin treatment, she began to smell herself and felt a bad/foul odor was released from her body. The patient associated these complaints with the new drug(empagliflozin) stopped two weeks ago. She also stated that all these complaints had disappeared one week after stopping the medication and there were no complaints at the moment. Conclusions. Here we report an unidentified body odor as a potential empagliflozin-associated adverse event. There was a close temporal relationship between empagliflozin intake and the development and the occurrence of the described odor.

Thyroid carcinomas associated with Graves? ophthalmopathy had been described in the literature, before. The rate of this coincidence is 1.1% - 7.1%. Papillary carcinoma is more common than thyroid cancer in Graves? disease. Herein, we present a 37-year-old male Graves? disease patient with thyroid papillary carcinoma.

Background. Fine needle aspiration biopsy (FNAB) is an important tool in the diagnosis of thyroid nodules. Aim. Our aim was to investigate the malignancy criteria in thyroid nodules by gray-scale ultrasonography (US) and duplex Doppler ultrasonography (DDUS), and their usefulness in reducing the number of unnecessary FNAB’s. Study design. This was a prospective observational study. Subjects and methods. 181 benign and 18 malignant thyroid nodules were evaluated by US and DDUS before FNAB or thyroidectomy. US was used to note size, shape, internal structure, nodule echogenicity, marginal properties, peripheral hypoechogenic halo, and microcalcifications. DDUS studies were used to evaluate the maximum and minimum flow velocity (Vmax and Vmin), systolic/diastolic flow velocity ratio (S/D), pulsatility index (PI), resistive index (RI), acceleration time (AT) and acceleration value. Results. Contour irregularity, size and presence of microcalcifications (p<0.001, p=0.02 and p=0.002, respectively) and S/D, Vmin, PI, RI and AT were significantly different (p=0.004, p=0.007, p=0.032, p=0.003 and p=0.003, respectively) were significant for malignant nodules. Benign and malignant nodules with or without suspicious US findings had similar DDUS findings. Vmax, Vmin, PI, RI, and AT were significantly different in the presence of microcalcification (p=0.043, p=0.001, p=0.031, p=0.04, and p=0.019 respectively). AT was significantly different in the case of absence of microcalcification (p=0.019). Comparing the irregular margins, Vmin, PI and RI were significantly different (p=0.014, p=0.003, and p=0.014 respectively). Conclusion. Benign and malignant thyroid nodules can be differentiated using gray-scale US findings and DDUS based indices together to reduce the number of unnecessary FNAB’s.
