ACTA ENDOCRINOLOGICA (BUC)

Background. Thyroid nodules are common; however, the association of two or more different tumors in the thyroid gland is unusual. We present a first case with the association of three histological types of thryroid tumors. To the best of our knowledge, this association has not been reported in the literature before. We aim here to highlight the possible coexistence of many lesions in the thyroid gland and to discuss treatment options. Case presentation. We report the case of a female patient who presented with a multinodular goiter. The final pathology after total thyroidectomy found the association of a multifocal papillary thyroid microcarcinoma arising within a Hurthle cells adenoma in a lobe and a noninvasive follicular thyroid neoplasm with papillary nuclear features in the other lobe. Due to the very low risk of recurrence, the patient was not treated with radioactive iodine. Conclusions. Many controversies remain about the management of Hurthle cells tumors and many variants of papillary thyroid carcinoma. Although the management of our case did not change, more studies are necessary to analyze the evolution of patients with multiple thyroid neoplasms. When discussing therapeutic options, the advantages and disadvantages should be considered case by case based on disease staging.

Zygomycosis is a frequently fatal infection in the immunocompromised and diabetic host. A 12 year old girl with type 1 diabetes presented in diabetic ketoacidosis and consolidation of right lung along with thymic abscess causing persistent respiratory symptoms. A diagnosis of\r\nmucormycosis was made on smear examination of the thymic aspirate. Intravenous amphotericin along with surgical excision of the abscess resulted in clinical cure. Thymic involvement as seen in this case is an extremely rare occurrence in a diabetic patient which has not been\r\nreported in literature so far .

Context. Adrenocortical carcinoma (ACC) is a rare neoplasm with an aggressive course and poor prognosis. The worldwide incidence is about 0.5 to 2 cases per million population per year. Oncocytic adrenocortical carcinoma is a rare histopathological variant of ACC with only a few reported cases in the literature. Case report. We report a case of an oncocytic variant of adrenocortical carcinoma in a 21-year-old male patient who presented with a left adrenal mass. Imaging studies confirmed a large left adrenal mass with involvement of the left renal vein and inferior vena cava. Endocrine workup showed mildly elevated serum cortisol levels. Discussion. Oncocytic AAC is a rare histopathological variant of ACC, as well as a rare subgroup of oncocytic adrenal neoplasms Hormonally active or functioning adrenocortical carcinomas most commonly secrete cortisol whereas co-secretion of multiple steroid hormones is a rare phenomenon. Conclusions. Surgery remains the mainstay of treatment, but most of the patients present late with large masses and eventually become unsuitable for curative resection.

We reported that in a 29-year-old male patient with hyperthyroidism, bilateral breast swelling appeared in three days after starting methimazole and gradually aggravated. Several days later, a small amount of transparent liquid could be squeezed out from bilateral mammary glands. Breast ultrasound confirmed gynaecomastia. The level of testosterone, estradiol and luteinizing hormone increased. After the patient continued taking methimazole for a while, gynaecomastia relieved. Testosterone, luteinizing hormone and thyroid functions restored to normal. The possible mechanisms included increased levels of serum total cholesterol and relatively decreased T3 after initiating methimazole.

Background. Prevention of complications is widely considered as the main aim of diabetes control. And diabetes education is the cornerstone for type 2 diabetes (T2D) management. However, traditional lecture-based diabetes patient education activities have small and shortlasting efficacy. Therefore, technology-based initiatives for diabetes patient education are urgently required. Objective. To evaluate Guessing, a popular game, as tool in increasing complication awareness of patients with newly diagnosed T2D during diabetes care. Patients and Methods. In a cohort study, 103 patients were split into Guessing Game group and control group. The opinions of patients and educators in Guessing Game group were surveyed. Patient performance was evaluated by test scores and the attendance to diabetes complication screening clinic. Results. A majority of patients and all educators believed that Guessing Game enhanced complication awareness. Educatees achieved higher total scores and test scores in “Fill in the Gaps” (one of 2 types of test item), more actively attended complication screening clinic, after using Guessing Game as an education tool. Conclusion. Guessing Game is an attractive and effective educational intervention to increase complication awareness of T2D patients.

Context. Diabetic peripheral neuropathy (DPN) is a common complication associated with long-term type 2 diabetes mellitus, although early diagnosis can improve prognosis. Objective. Our objective was to develop a simple protocol for early diagnosis of DPN in Chinese type 2 diabetic patients. Subjects and Methods. A total of 209 type 2 diabetic patients were included; these patients were categorized as symptomatic and asymptomatic group based on their symptoms. Clinical data of these patients were recorded and they were screened for DPN by vibration perception threshold test (VPT), 10-G nylon monofilament test, temperature identification, and the tendon reflex test. Results. The total combined rate of patients who were tested positive for DPN with all four screening methods was 68.7%. Patients tested positive for DPN were significantly older and had a longer disease duration than those who were tested negative (p<0.01); however, glycated hemoglobin levels, presence of hypertension, and gender did not differ significantly between them (p>0.05). Among screening methods, the highest positive rate observed among patients screened with the VPT test was 63.64% as compared to other tests. The total positive rate for temperature discrimination, 10-G monofilament and tendon reflex test were 26.79%, 11.96 % and 17.22 % respectively. In asymptomatic group VPT showed the highest positive rate for DPN (48.41%). Conclusions. The combination of four simple methods can improve the detection rate of DPN and identify subclinical cases. Abnormal vibration perception was the most common feature of DPN and it was associated with both disease duration and the age of the patient.

Objective. Type 2 diabetes mellitus (T2DM) is a major health problem worldwide. Earlier studies have reported that pancreatic fat content (PFC) and liver fat content (LFC) are risk factors for T2DM. The aim of the present study was to demonstrate the relationship between PFC, LFC and T2DM. Methods. A total of 70 T2DM subjects and 30 nondiabetic volunteers who underwent Dixon-based magnetic resonance imaging (MRI) method at Yixing People’s Hospital between December 2018 to December 2020 were included in the study. The three-point Dixon (3p-Dixon) method was used to measure the fat content in the pancreas and liver. Clinical indices including gender, age, body mass index (BMI), total cholesterol, triglyceride, glucose and C peptide levels were collected. The association between PFC, LFC, and OGTT-derived parameters was examined by Pearson and Spearman correlation analyses. Results. T2DM subjects had higher PFC and LFC than those measured in the non-diabetic subjects (p <0.05). PFC and LFC were associated positively with OGTT-derived parameters such as insulin secretion, insulin resistance, and early- and late-phase insulin secretion in the male T2DM subjects(p <0.05), but not in the non-diabetic and female T2DM subjects. The relationship between PFC and OGTTderived parameters was also more obvious than that for LFC in overweight and obese male patients with T2DM whose BMI was >24 kg/m2. Conclusion. PFC and LFC were both associated with β-cell dysfunction and insulin resistance in males with T2DM. The relationship between PFC and β-cell dysfunction and insulin resistance was more obvious than that observed for LFC in overweight and obese male T2DM patients. More attention should therefore be paid to PFC in clinical settings.

Context. Polycystic ovary syndrome (PCOS) is associated with increased prevalence of preeclampsia (PE); microRNAs (miRs) could play an important role in the pathogenesis of PE and PCOS. Objective. To investigate the expression levels of miRs 155-5p and 518b in blood leukocytes of patients with PE and PCOS. Design. Using real-time quantitative PCR method, miR-155-5p and miR-518b were examined from PE, PCOS, PE+PCOS, and controls. Subjects and Methods. The relative expression of the target miRs in patient samples was compared to control samples. The results were calculated as relative quantification values. Results. Confounding variables were controlled using analyses for covariance. Significant differences were observed in miR-155-5p (p=0.008) and miRNA-518 (p=0.016) expression levels among the groups. miR-155- 5p (p=0.014) and miR-518b (p=0.036) were upregulated in PCOS patients and miR-518b (p=0.028) were increased in cases with PCOS+PE. Near significant difference was found (p=0.06) in miR-518b expression levels in cases with PE, compared to controls. miR-518b was observed to be positively correlated with alanine transaminase in cases with PE (r=0.80; P=0.017) and PE+PCOS (r=0.80, p=0.017). Conclusions. Our preliminary findings suggested that expression profiling of miR-155-5p and miR-518b in blood leukocytes were upregulated in pregnant women with PCOS. Moreover, miR-518b was found to be related to PE in cases with PCOS

The hemostatic balance is a complex system where the delicate equilibrium is regulated by several factors including hormones. Hypothyroidism, as a common disease in the general population, affects both the coagulation and fibrinolytic systems. However, the reliable clinical evidence is so far lacking and published data remain conflicting. According to the severity of the disease, we divided all study subjects into four groups: 50 controls, 47 patients displaying subclinical hypothyroidism, 41 patients displaying moderate hypothyroidism (TSH≤50 mU/L), and 53 patients displaying severe hypothyroidism (TSH>50 mU/L). We investigated various coagulation parameters including: activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen (FIB) and international normalized ratio(INR). Compared with control subjects, patients with subclinical hypothyroidism displayed hypercoagulability, as reflected by shorter APTT levels and increased FIB levels. The patients with moderate hypothyroidism had only increased TT levels without any significant variation in the other studied parameters, which suggested neither obvious bleeding tendency nor clotting tendency. The patients with severe hypothyroidism displayed a bleeding tendency, as reflected by higher APTT, PT, TT, INR levels and decreased FIB levels. The patients with different hypothyroidism stages display various abnormalities of coagulation.
