    A Rare Cause of Pituitary Apoplexy: Cabergoline Therapy

    Acta Endo (Buc) 2018 14(1): 113-116 doi: 10.4183/aeb.2018.113

    Pituitary apoplexy (PA) is a life-threatening clinical syndrome. Dopamine receptor agonists are the drugs of choice in the treatment of prolactinomas. The use of cabergoline is reported to cause an increased risk of PA, particularly in macroprolactinomas of cystic nature. In this report, we present a patient with a cystic macroprolactinoma who developed PA on the 16th week of cabergoline treatment.

    A Case of Acromegaly in the Presence of Coincidental Liver Cirrhosis

    Acta Endo (Buc) 2012 8(1): 119-124 doi: 10.4183/aeb.2012.119

    Context. Acromegaly is a rare and serious syndrome and commonly associated with pituitary neoplasm. Classic cause of acromegaly in adults is the tumors of the somatotrophs that secrete growth hormone. Cirrhosis is the end stage of chronic liver disease and commonly a cause of death. It is\r\ncharacterized by diffuse hepatic fibrosis resulting in altered construction of the lobular parenchyma with widespread connective tissue septae, circumscribed\r\nregenerative nodules of hepatocytes and anastomoses between vascular channels linking portal and central vessels.\r\nObjective. To report the simultaneous cases of acromegaly and cirrhosis.\r\nCase report. A 62-year old, male patient came to the hospital complaining of severe abdominal swelling. Laboratory and imaging findings were compatible with the\r\npresence of hepatitis B virus related cirrhosis together with acromegaly. In this case, he had high GH level but lower IGF-1 level because of hepatic failure which can\r\nimpair IGF-1 production by the liver. Definitive diagnosis was made by pituitary MR and a 1 cm in diameter tumor was\r\ndetected.\r\nConclusion. This paper showed that cirrhosis can result in a low IGF-I level in patients with acromegaly. There is no\r\nprevious report available of the in the presence of coincidental combination of acromegaly and cirrhosis in a patient.

    Is Repeat FNAB Necessary For Thyroid Nodules with ND / UNS Cytology?

    Acta Endo (Buc) 2022 18(1): 127-133 doi: 10.4183/aeb.2022.127

    Context/Objective. The standard approach is to perform repeat FNAB (rFNAB) in thyroid nodules with nondiagnostic (ND) / insufficient (UNS) cytology. However, due to the nature of these nodules, recurrent FNABs may also be insufficient. Therefore, by comparing the clinicalradiological- pathological parameters of nodules with a definite diagnosis of excision, we questioned the possibility of patient management without rFNAB. Methods. Clinical-radiological parameters of 275 nodules belonging to 264 patients in the ND/UNS aspiration group with definite pathological diagnosis after surgery were determined. Under the guidance of these parameters, those with and without rFNAB were compared. Results. The incidence of malignancy was found to be significantly higher in nodules without rFNAB compared to nodules with rFNAB (p = 0.036). In addition, the incidence of malignancy in BC-1 nodules without rFNAB was significantly higher than in nodules with rFNAB result also BC-1 (p = 0.009). In all cases, nodule size smaller than 10 mm and border irregularity were found to be statistically significant for malignancy (p <0.020, p <0.002). When looking at the distribution of rFNAB results, a significant correlation was observed with female gender, solid component, hypoechogenicity, border irregularity and halo loss around the nodule in patients with BC-4,5,6 cytology results (respectively, 0.005 / 0.031 / 0.001 / 0.012 / 0.004). Conclusion. rFNAB did not show the expected effect in ND / UNS nodules. We recommend direct surgical excision without rFNAB for nodules with border irregularity, solid structure, halo loss and hypoechogenicity, which should be considered more important in female patients.

    Association of Pancreas Volume and Insulin Resistance with Abdominal Fat Distribution in Type-2 Diabetes as Evaluated by Computed Tomography

    Acta Endo (Buc) 2017 13(2): 168-173 doi: 10.4183/aeb.2017.168

    Purpose. We aimed to assess the relationship between the regional body fat distribution and insulin resistance and pancreas volume (PV) in type-2 diabetes (DM) patients. Methods. Fifty-three consecutive type-2 diabetic and 51 non-diabetic patients matched by age, gender and body mass index (BMI) were enrolled. Subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), waist circumference, and PV were measured with computed tomography. Insulin resistance was assessed by the homeostasis model assessment of insulin resistance (HOMA-IR). Results. Patients with type-2 DM had significantly lower PV than non-diabetic individuals. HOMA-IR ranged from 0.74 to 6.24; and from 0.37 to 3.26, in type-2 DM patients and non-diabetics, respectively. VAT was positively correlated with HOMA-IR in two groups. There were inverse correlations between PV and VAT and VAT/SAT but only in diabetics. Conclusions. The VAT/SAT ratio may reflect the possible role of VAT to better understand the pathogenesis of obesity-related disorders in patients with type-2 DM.

    The Effect of Diabetes Symptoms on Quality of Life in Individuals with Type 2 Diabetes

    Acta Endo (Buc) 2021 17(2): 186-193 doi: 10.4183/aeb.2021.186

    Objective. This study aimed to investigate the effect of symptoms of diabetes on the quality of life of individuals with Type 2 diabetes. Method. The study used a cross-sectional design. No sampling procedure was employed in the study; instead, 410 individuals presenting to the Balikesir Atatürk City Hospital Endocrinology and Internal Medicine Polyclinics between December 2016 and July 2017, diagnosed with Type 2 diabetes, and meeting the inclusion criteria were enrolled in the study sample. The study data were collected with a “Socio-demographic Characteristics Questionnaire”, the “Diabetes Symptom Checklist”, and the “SF-36 Quality of Life Questionnaire”. Results. The participants obtained the highest mean scores from the hyperglycemia subscale of the Diabetes Symptoms Checklist (3.35±0.60) and the mental health subscale of the SF-36 Quality of Life Questionnaire (50.65±8.10). The hypoglycemia, cardiology, psychology, and neurology variables included in the model were statistically significant and predicted 35% of the mental subscale score of the SF 36 questionnaire. SF 36 physical subscale score increased as the hypoglycemia, cardiology, psychology, and neurology scores decreased (p<0.05). Conclusion. The participants obtained high scores from the hyperglycemia subscale of the diabetes symptom checklist and mental health subscale of the quality of life questionnaire. Diabetes symptoms were found to affect the quality of life of individuals with diabetes.

    Lithium-Induced Nephrogenic Diabetes Insipidus Responsive to Desmopressin

    Acta Endo (Buc) 2019 15(2): 270-271 doi: 10.4183/aeb.2019.270

    Nephrogenic diabetes insipidus (NDI) is the most common renal side effect seen with lithium therapy. Persisting cases after the cessation of the therapy may be seen when lithium therapy is continued for too long. Although desmopressin treatment is not one of the accepted treatment modalities for NDI, there are few reports using desmopressin treatment in unresponsive cases. Herein, we reported the fourth lithium-induced NDI case in the literature responsive to desmopressin therapy.

    Diabetes Mellitus with Left Transverse and Sigmoid Sinus Thrombosis Extending into the Internal Jugular Vein

    Acta Endo (Buc) 2011 7(2): 283-290 doi: 10.4183/aeb.2011.283

    Background. Cerebral vein and sinus thrombosis (CVT) is less encountered, compared to arterial stroke. Commonly witnessed symptoms are headache, nausea, vomiting, confusion, aphasia, seizures, cranial nerve dysfunction and motor or sensorial deficits. The diagnosis is accurately determined by the help of MRI and MR venography. Multiple risk factors associated with CVT are present. Venous thrombosis tends to occur when there is an imbalance between prothrombotic and thrombolytic processes.\r\nCase report. In this report, a patient with CVT extending from left transverse and sigmoid sinuses to jugular vein and diagnosed with diabetes mellitus (DM) during this period\r\nwas discussed in light of literature. The 55-year-old man was evaluated in the neurology clinic with the complaints of headache, nausea, vomiting and blurred speech. On neurologic examination, he was diagnosed with sensorial aphasia and consequently, with DM over the hospital stay. On the cranial MR venography, CVT thrombosis was detected, extending from transverse and sigmoid sinuses to internal jugular vein. Decreased level of protein C and shortage of aPTT were\r\nfound. Anticoagulant treatment was carried out. All complaints were improved.\r\nConclusion. In our subject, the existence of decreased protein C and shortage of APTT, along with DM, is a situation to increase hypercoagulability and the risk of cerebral vein and sinus thrombosis.

    Hormonal Regulation of Carbohydrate and Fat Metabolism in Women with Different Obesity Types in the Food Deprivation Test

    Acta Endo (Buc) 2019 15(3): 355-359 doi: 10.4183/aeb.2019.355

    Context. The dominant type of adipose tissue accumulation in the body is associated with the peculiarities of using key substrates in energy metabolism and their hormonal regulation. Hormonal and metabolic parameters were investigated in women with android and gynoid obesity before and after the short-term food deprivation test. Results. At baseline, at gynoid obesity as compared to android obesity, the women’s blood contained lower glucose and insulin levels and higher FFA levels. The reaction to food deprivation manifested by a decrease in glucose level and an increase in FFA level in the blood is less pronounced in women with gynoid obesity than in those with android obesity. At the same time, a similar (though varying in expression) decrease in insulin level and elevated levels of glucagon, growth hormone and thyroxine were revealed in women’s blood in both groups. Blood cortisol level increased in women with gynoid obesity and remained unchanged in those with android obesity. Conclusions. More pronounced activation of hormonal mechanisms for maintaining blood glucose levels at gynoid obesity as compared to android one suggests that glucose is the preferable substrate for energy metabolism at gynoid obesity in women.

    Plurihormonal Pituitary Adenoma: Acromegaly Associated with Subclinical Cushing’s Disease

    Acta Endo (Buc) 2015 11(3): 389-393 doi: 10.4183/aeb.2015.389

    A 52-year old women was diagnosed with acromegaly 5 years ago, and transseptal transsphenoidal pituitary microsurgery has been performed. Later the patient did not come to controls and the complaints prior to operation growth of the hands and feet, headache, sweating and resistant hypertension have continued. She was referred to our clinic with the same complaints. Physical examination showed typical acromegalic features without typical Cushingoid features. Magnetic resonance imaging of the brain revealed the presence of a pituitary macroadenoma. Basal plasma levels of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels were high. GH suppression was not observed in 75 gr oral glucose suppression test. Due to refractory hypertension and central obesity hypothalamo-pituitaryadrenal (HPA) axis was evaluated. HPA showed a lack of circadian rhythm of adrenocorticotropic hormone (ACTH) and cortisol, non-suppressibility to 1 mg overnight and classical 2 day low-dose dexamethasone, but suppressibility to high-dose (8 mg) dexamethasone. The tumour resected by transsphenodial surgery was histopathologically consistent with the diagnosis of adenoma. Immunostaining showed GH and ACTH producing cells. After surgery plasma GH and IGF-1 levels decreased to normal along with normalization of HPA axis. Hypertension disappeared without medical treatment after removal of the pituitary tumour. This is a very rare case of GH-producing pituitary adenoma causing typical acromegaly with concomitant production of ACTH causing subclinical Cushing’s disease.

    Normocortisolemia after Ten Days Octreotide Treatment in a Patient with Ectopic Cushing's Syndrome Due to Bronchial Carcinoid

    Acta Endo (Buc) 2013 9(3): 467-472 doi: 10.4183/aeb.2013.467

    Context. We report the use of subcutaneous somatostatin injection three times a day to decrease hypercortisolism in a patient who had Cushing’s syndrome induced by bronchial carcinoid tumour progressive pneumonia due to immune suppression. Subject and Method. A 46-yearold man with 7-month history of DM type-2, hypertension and cerebrovasculardisease, vertebral compression-fracture was admitted to our clinic. Physical examination was consistent with Cushing’s syndrome. Laboratory results revealed hyperglycemia (143 mg/dL; reference range, <100 mg/dL) and hypokalemia (2.29 mEq/L; reference range, 3.5-5.1 mEq/L). His morning serum cortisol was 40 μg/dL (reference range 6.7- 22.6 μg/dL), urine cortisol-excretion was 2245 μg/24 hours (reference range 58-403 μg/24 hours), after 1 mg dexamethasonesuppression test serum cortisol was 28 μg/dL (6.7-22.6 μg/dL) and ACTH 354 pg/mL (reference range 7.9-66 pg/mL). Adrenal CT and hypophyseal MRI were normal. An ectopic source was searched for Cushing’s syndrome. Chest CT scan of the right lung showed 12x9 mm nodule. High fever cough occurred on the followp. Chest radiograph revealed diffuse pneumonic infiltration. Despite 3-drug antibiotic combination therapy, infection did not improve. Subcutaneous injection of octreotide 3x100 μ/g was initiated to decrease hypercortisolism. The infection improved rapidly after the therapy. The morning serum cortisol, urine cortisol-excretion, ACTH was at the upper normal range (77.1 pg/mL, reference range 7.9-66 pg/mL) on 10th day of treatment. The patient was a consulted for surgery and the nodule was excised. The pathology was consistent carcinoid tumor. Conclusion. Subcutaneous octreotide treatment may be helpful to gain time for exploring the focus in ectopic cushing’s syndrome and to control the serious infections due to hypercortisolism.
